SASSI and the MSC: How effective have they been with reaching consumers in Cape Town and raising their awareness
No full textThe 'sustainable seafood movement' is over 20 years old, and has made use of numerous methods in an attempt to educate consumers about seafood. In South Africa, there are two such campaigns: the Marine Stewardship Council (MSC) and the Southern African Sustainable Seafood Initiative (SASSI). This study aimed to investigate the awareness of consumers at major retail outlets in Cape Town of these initiatives, and to link awareness with seafood consumption behaviour. It used face-to-face surveys, which were conducted at all times of the week in outlets of three major supermarket chains located at five middle-class shopping centres. Aspects investigated included consumers': recognition of the MSC and SASSI; preferred seafood species; production method(s); and favoured sources of seafood. The data were analysed by means of chi-squared (χ2) analysis. The MSC label was recognised by slightly over a tenth of the consumers and SASSI by just less than half. Overall it was found that shoppers were more concerned about the quality and value for money, than the type, sustainability and size of their seafood. Consumers who shopped at the retail outlets which have a working relationship with SASSI did not show a higher awareness of SASSI. Even the consumers who were the most aware of SASSI and/or the MSC, and indicated that they considered sustainability a factor when making seafood choices, still favoured species from fisheries the sustainability of which is classified as problematic. The results point to raised awareness, yet unchanged purchasing behaviour

The species belongs to the subgroup with longitudinal dorsal color pattern. It resembles <i>M. albivittis</i> because of the dorsal overall light hue in which only yellow and reddish are present wereas black or dark brown patches are totally lacking. However, <i>M. albivittis</i> shows two longitudinal reddish lines on elytron (only one, much larger in <i>M. sekerkai</i>). Besides, <i>M. albivittis</i> has narrower, less transverse pronotum with stronger and closer punctuation. Median lobe of aedeagus is different as well.</p> <p> <i>Description of male</i>.

All paratypes with our label: Pachybrachis holerorum n. sp. paratypus Montagna & Sassi des. [red, printed]. Paratypes in MSNM, DSPC, MMPC, MSPC, MDPC. Etymology. The name is genitive plural of holus, used by the Roman poet Lucilius to indicate leguminous forbs. Description of male. Total length: male = 2.9 ± 0.1 mm. Head yellow except vertex, a median longitudinal stripe with bifurcated apex along frons, antennae sockets, anterior margin of clypeus black. Frons shining, covered with fairly impressed punctation, denser on clypeus and above insertion of antennae, sparser on frons. Antennae filiform, brownish, segments 1–5 partly yellowish. Pronotum black with yellow bands along anterior and lateral borders; anterior band lightly thickened at anterior angles and with short median posteriorly directed vitta; two anteriorly directed yellow lines from basal margin at sides of scutellum, 1.5 times wider than long, regularly curved at sides, with maximum width at about middle; punctation deep, denser at sides, slightly sparser on disc. Scutellum elevated, black, minutely punctate, apically truncate. Elytra coarsely punctured, partially arranged in striae; interstices raised, black with yellow pattern slightly raised from black surface, arranged as follows (spots and vittae may be interrupted or absent): narrow bands and vittae along anterior, lateral and posterior margins; narrow vitta along posterior half of sutural margin; two elongated spots near suture, plus one behind scutellum and one larger, in median position; longitudinal vitta on anterior margin lateral to humeral callus; post-median spot on disc; several smaller spots variously arranged on elytral surface. Epipleura black in posterior half, partly yellow anteriorly, with one or two series of irregularly aligned punctures on edges. Venter black, mesepimera with yellow spot, sometimes indistinct. Abdominal ventrites sparsely punctured and covered with rather sparse, long whitish hairs; ventrite 5 with shallow depression, glabrous. Legs yellow, fore femora blackish along posterior edge; median and hind femora largely darkened along basal half, fore tibiae yellow; meso and metatibiae darkened at apex; tarsi mostly yellow, more or less darkened towards apex. First protarsomere moderately broadened, as wide as apex of tibia. Apex of aedeagal median lobe (figure 4) acute, lateroventrally with row of white hairs, shaft thin and elongated, slightly careened along ventral surface, venter straight in lateral view. Female differs from male in: larger and stouter body (length 3.3 ± 0.1 mm); frons broader and, as result, eyes more separated; generally reduced yellow pattern; first protarsomeres significantly narrower than tibiae apically; rectal apparatus (figure 5 a,b) with two dorsal and one ventral sclerites; dorsal sclerites short and narrow, slightly wider than rectum, transverse connection across dorsal fold not perceptible, so sclerites essentially reduced to the apodemes only; ventral sclerite ribbon-like, evenly pigmented in the middle, with large and rounded apodemes at both ends, wider than rectum; dorsal and ventral sclerotizations of lateral fold present; spermatheca (figure 5 c) sickle-shaped, lightly pigmented, basal part not swollen; base reflexed, with gland and duct insertions well sclerotized, so that it seems bifurcated; duct not coiled, quite short, its insertion on bursa copulatrix not enlarged and only feebly and briefly pigmented. Diagnosis. Pachybrachis of medium-small size, characterized by elytral pattern, with marginal yellow stripe from anterior edge, to and around posterior margin, then along apical half of suture. This stripe interrupted only at humeral callus. Similar elytral marginal stripes are present in P. karamani Weise and P. fimbriolatus Suffrian, with which the new species forms a group, based on morphology. In P. karamani, the elytral yellow spots are generally smaller, and the irregularly distributed small spots that characterize P. holerorum are almost entirely missing. Pachybrachis fimbriolatus is distinguished from the new species by: less transverse and more minutely and densely punctured pronotum, reduced elytral yellow spotting, particularly, postmedian dot nearly always absent. The new species clearly differs from the all Pachybrachis species in the shape of the median lobe of aedeagus (figures 4 and 6). Distribution. The new species is endemic to Northern Apennines, Italy. The type locality is Emilia Romagna, Piacenza Prov., Passo del Pellizzone (also written “Pelizzone”) (44 ° 40 ' 48.84 "N 9 ° 44 ' 42.66 "E). Remarks. The biology of P. holerorum is poorly known. At Passo del Pellizzone it was collected in early June on Lotus herbaceus. This possible host was confirmed by the gut analysis of plant DNA from specimens at this locality. The preference of many species of the genus Pachybrachis for Fabaceae is well known (Jolivet and Hawkeswood 1995). Pachybrachis holerorum is restricted to the north and west Apennines and P. k a r a m a n i is on the Adriatic slopes of North and Central Apennines (Sassi 2006). Molecular and morphological evidence show that Pachybrachis holerorum and P. karamani are recently diverged sister species in adjacent allopatric ranges, suggesting vicariant origin for the two species. We take the opportunity here to designate a lectotype for P. karamani, to fix the identity of this species which is similar to P. holerorum. The syntypic series of P. k a r a m a n i consists of five specimens. We designate a male as lectotype, labelled as follows: Spalato (handwritten, white label) / Typus (printed, red label) / karamani Ws. (handwritten, white label) / Zool. Mus. Berlin (printed, yellow label) / Sintypus (printed, red label) / Pachybrachis karamani Weise, 1893 labelled by MNHUB 2012 (printed, red label).

Concluding remarks In our study of these Pachybrachis populations, the combination of three different approaches (morphological features of the aedeagus, nucleotide distance values and a method delimiting species based on single-locus molecular data), has provided evidence for a new species and its sister taxon. The results contained in this work strongly confirm the urgent need to increase efforts to uncover the real biodiversity of the European fauna, in particular the Mediterranean region.

Brazil.</p> <p> <i>Diagnosis</i>. The most similar species to <i>M. geiseri</i> in colouration is <i>M. taeniatellus</i>, and the strong chromatic variability makes the attribution of specimens to one or to the other species problematic based on this characteristic alone; however, on the ventral surface of the aedeagal median lobe, the setose depression on each side in <i>M. geiseri</i> is downwardly sharply delimited from the deep rounded pit, while in <i>M. taeniatellus</i>, the setose depressions and pits are not clearly separated from each other. The longitudinal median carina is also significantly wider at the aedeagal apex in <i>M. geiseri</i> than in <i>M. taeniatellus</i>.</p> <p> <i>Description of male.</i> Habitus in Fig. 9a–b (HT). BL = 3.3–4.1 mm, BW = 1.9–2.4 mm, PL = 1.2–1.4 mm, PW = 1.7–2.1 mm. Interocular distance 4.9–6.1 % of BL.</p> <p>Head black with bell-shaped yellow marking on frons and clypeus. Small sickle-shaped yellow spot along upper margin of eyes. Labrum piceous, slightly lighter on sides. Vertex quite dull with few, scattered setigerous punctures close to eyes margins. Frontoclypeal area with sparse, pale setae above all along eyes rim, and few shallow punctures. Mid-cranial suture short, well impressed. Ocular lines narrow, strictly adhering to ocular rim. Ocular canthus deep, quite densely punctured with short, semi-erect setae. First five antennomeres sublucid, yellowish, 3-5 rod-shaped, 6-11 totally darkened, dull, more flattened, and more diffusely setose (Fig. 9h).</p> <p>Pronotum black with yellow pattern as follows: two large yellow stripes along lateral margins, briefly widened close to anterior margin; linear stripe along median line, sometimes very short or missing, not reaching anterior and posterior margins; little U-shaped spot just in front of scutellum. Sometimes this U-shaped spot almost straightened in narrow transverse band running along central section of posterior margin. Pronotal shape tronco-conical. Lateral margins thin, almost not visible in dorsal view, evenly and mildly curved with maximum width just behind half length. Surface moderately shiny with scattered, very fine, slightly lengthened punctation in central part of disc, rounded and coarser toward sides. Posterolateral impressions shallow but detectable.</p> <p>Scutellum black, moderately raised, trapezoidal, with truncated apex. Surface smooth, with few, tiny, recumbent, whitish setae.</p> <p>Elytron yellow with large black band just behind midline, extended from suture to lateral margin, often broadened at middle in angulate, forwardly directed projection. Suture narrowly black. Epipleuron yellow, narrowly darkened along margin. Elytral outline parallel-sided, very weakly flattened on disc. Lateral margin narrow, in dorsal view visible from apex up to midline. Elytral surface moderately shiny with well impressed punctures arranged in almost regular rows, easily discernible on elytral apex. On lighter area bottom of punctures only slightly darker than interval surface. Intervals flat. Postscutellar area not raised. Humeral callus prominent, impunctate. Epipleuron smooth, impunctate, with mildly convex surface.</p> <p>Pygidium piceous with yellow patches along sides, covered with recumbent whitish setae and sparse shallow punctures.</p> <p>Ventral parts of thorax piceous with first visible abdominal ventrites bordered with yellow. Hypomera, mesoepimera and mesoepisterna almost glabrous, impunctate or with scarce shallow punctures. Metaepisterna, metasternum and abdominal ventrites densely setose. Prosternal process weakly grooved, sparsely punctured with long setae, and slightly raised short triangular apex. Legs yellow to brownish, often with tibial apex and tarsi infuscate.</p> <p>Fifth abdominal ventrite with deep, elliptical, transversally arranged, bald, impunctate median depression. Posterior margin almost straight. Median lobe of aedeagus (Fig. 9c–e) almost square in transverse section, slightly compressed laterally with fairly widened, bluntly triangular apex. Setose depressions deeply impressed, ear-shaped, with setae short and scattered, also distributed along lateral rim of wide, flat, longitudinal carina running across whole ventral surface. Setose depression neatly separated downward by sharp rim from large, deep, elliptical pit. Aedeagal ventral surface convex in lateral view with a large depression at middle.</p> <p>Endophallus (Fig. 9f) with sclerite I weakly sclerotized and pigmented, reduced to flattened fold on edge of membranous part, terminated with small denticle. Dorsal spicule not detectable. Sclerite II well pigmented, in lateral view slightly lengthened with slender process upward directed. Sclerite III sickle-shaped, with rounded arch and very short, blunt, straight apex. Branches of sclerite IV slightly shorter than sclerite III in folded-up structure, regularly arched towards ventral direction, weakly broadened at base. Surface of sclerite IV smooth.</p> <p> <i>Female</i>. BL = 4.3–4.6 mm, BW = 2.6–2.8 mm, PL = 1.5–1.6 mm, PW = 2.3–2.6 mm. Interocular distance 11.6–13.0 % of BL.</p> <p>Females differ in a stouter body and wider interocular distance. The light colour pattern on the head is reduced to a small, subrounded spot at the center of the frontoclypeal area; the lateral pronotal yellow stripes are fairly wide and the remainder of yellow patches on pronotum are missing.</p> <p>The vasculum of the spermatheca (Fig. 9g) is moderately pigmented, S-shaped, slender, with the proximal lobe not swollen. The distal lobe is long, slender, rather straight along the median section, then tapered and bent downward at the apex. The ampulla is scarcely pigmented, sitting just at the basal apex of the vasculum. The duct and sperm gland insertions are perceptibly distinct. The duct is short, quite rigid near the vasculum, forming a series of several turns more than coils, then almost straight, more slender in proximity to the bursa copulatrix. The insertion on the bursa copulatrix is robust, shortly conical, strongly pigmented.</p>Published as part of <i>Sassi, Davide, 2022, Revision of the Metallactus taeniatellus species group (Coleoptera: Chrysomelidae: Cryptocephalinae), pp. 251-282 in Zootaxa 5125 (3)</i> on pages 273-275, DOI: 10.11646/zootaxa.5125.3.1, <a href="http://zenodo.org/record/6443765">http://zenodo.org/record/6443765</a>

The synonymy appears without further comments in the subsequent catalogues (Clavareau, 1913 and Blackwelder, 1946) but with the acknowledgement of the priority of the epithet <i>larvatus</i>. In the collections studied by me (for instance BMNH and MNHUB) the two species appear mixed up and in any case with confused determination, and the epithets <i>larvatus</i>, <i>decoratus</i> and <i>spadiceus</i> used in a very imprecise way. Even though the epithet <i>decoratus</i> appears in a recent work (Niño-Maldonado <i>et al.</i>, 2014) correctly referring to the taxon present in Mexico but without any comments or critical discussion, it is considered useful to formally confirm the species status of <i>G. decoratus</i> as a distinct species from <i>G. larvatus</i>.</p> <p> <i>Scolochrus spadiceus</i> Suffrian, 1852: 131 (original description); Suffrian, 1858: 392 (taxonomic notes).</p> <p> <i>Scolochrus decoratus spadiceus</i>: Jacoby 1880: 61 (as subsp. of <i>G. decoratus</i>, taxonomic notes).</p> <p> <i>Griburius spadiceus</i>: Clavareau, 1913: 90 (as syn. of <i>G. larvatus</i>, catalogue); Blackwelder, 1946: 640 (as syn. of <i>G. larvatus</i>, catalogue). <b>Syn. nov.</b></p> <p> <i>Griburius spadiceus</i> was given the status of “variety” by Jacoby (1880), so, strictly speaking, it should have been considered at a subspecific level, but in the following brief discussion, Jacoby seemed to give no weight to this chromatic form. Confirming this, there is the fact that the taxon was no longer mentioned in the <i>supplementum</i> (Jacoby, 1889). However, given the present confusion in the literature among the three epithets <i>larvatus</i>, <i>decoratus</i> and <i>spadiceus</i>, a formal statement of new synonymy is given here to clearly establish the status as a full synonym of <i>G. decoratus</i>.</p> <p> <i>Types.</i> Suffrian did not mention the number of the specimens of <i>Griburius decoratus</i> available for the study, but he gave a long and detailed description of the colour pattern variability and pointed out some features for both males and females, therefore he was able to study a quite high number of specimens. To confirm this, he gave an unusual long (10 items) list of private and public collections as depositories of the available material. He pointed out seven “variants” on the basis of the elytral colour pattern, but he clearly did not give this variation any taxonomic significance because none of those “variants” were given a name, and no described chromatic pattern was linked to a geographic datum. On the other hand, he was convinced he was describing a Mexican species, as he wrote: “From Mexico (Oaxaca) and probably widespread there and not rare, since it is present as the most common species in almost all the collections that I have compared”. The inspection of the collections available at present, allowed to trace down four syntypes in MNHUB (two from Mexico and two from Texas, which is not mentioned in the original description) and three syntypes in BNHM (all of them from Mexico). Unexpectedly, the two specimens from Texas in MNHUB turned out to belong to a different species with respect to the reminders. Since Suffrian stated that his species was a Mexican species, as mentioned above, the name-bearing specimen was chosen accordingly. Consequently, the Texan specimens turned out to belong to a new taxon which is described below (<i>Griburius rileyi</i> n. sp.). It might be objected that, being the locality not mentioned in the description, the specimens should be excluded from the type series. This would be a sensible point, but it should be noticed, on the other hand, that the catalogue number (23993) makes them fully embedded in a long list of material unquestionably seen by Suffrian and used as the basis for the description of several taxa. Moreover, it has already been pointed out (Sassi, 2018) that Suffrian was sometimes not very precise in reporting all the data on the attached labels. Taking all these circumstances into account, the Texan specimens were considered part of the type series.</p> <p> In order to stabilize the epithet, the typification was made as follows.

Tamaulipas (Niño-Maldonado <i>et al.</i>, 2014). The ambiguous type locality of <i>G. spadiceus</i> could indicate its presence in Nicaragua, but this country record remains unconfirmed.</p> <p> <i>Distribution.</i> Belize, Guatemala, Honduras, Nicaragua?, Mexico (new to Belize, Guatemala).</p> <p> <i>Diagnosis</i>. Very similar to <i>G. rileyi</i> and <i>G. larvatus</i>, this species is distinguished from both by the greater extension of the dorsal black pattern. In particular, the two spots on the disc of the pronotum tend to be angular, and almost always touch the anterior margin and, sometimes, also the posterior one. The tendency of the elytral spots to fuse is more developed than in the two species mentioned above, and therefore the pattern with two dark transverse bands, one basal and one postmedian, is very common. The examination of the aedeagal median lobe allows a more reliable identification: in ventral view, in <i>G. decoratus</i> the apex is shorter, its sides forming almost right angles with the profile of the aedeagal tube. In <i>G. rileyi</i> and <i>G. larvatus</i> the sides of the apex form a much more open angle.</p> <p> <i>Description of male.</i> BL = 3.9–4.8 mm, BW = 2.4–3.0 mm, PL = 1.4–1.9 mm, PW = 2.3–2.8 mm. Interocular distance 2.6–4.2 % of BL.</p> <p>Head (Fig. 5d) yellow with vertex, surface between upper lobes of eyes and insertion of antennae black. Labrum yellow. Vertex matt, sparsely and shallowly punctured with very short, recumbent, whitish setae. Surface of frontoclypeal area matt as well, with sparse, weakly impressed punctation and scattered setae. Longer setae only between antennal insertions. Mid-cranial suture well detectable on lower part of vertex and between upper lobes of eyes. Upper lobes of eyes close to each other along midline, but always separated by distinct strip of frons space. Ocular lines narrow, marked by row of punctures, strictly adhering to ocular rim up to ocular canthus. Ocular canthus large not differentiated in punctation and setosity from the remainder of frontoclypeal surface. Antennae (Fig. 5m) with antennomeres 1–2 yellow, 3–11 progressively darkened; antennomeres 3–5 bright, subcylindrical; antennomeres 6–11, dull, more flattened and more diffusedly setose.</p> <p>Pronotum yellow with two large, angulate black spots extended from anterior margin up to posterior half of disc. Sometimes such spots reaching posterior margin. Pronotal shape roughly elliptical, moderately transverse, perceptibly flattened on disc. Lateral margins narrow, not visible from above, regularly curved so that maximum width nearly at middle. Surface moderately shiny with scattered, fine punctation at middle of disc. Punctures coarser and more deeply impressed along sides and in proximity of posterolateral impressions. Posterolateral impressions well distinguishable and obliquely arranged, marked by some strong punctures at bottom of depression. Pronotal posterior margin thickened along posterolateral impressions.</p> <p>Scutellum yellow, sometimes vaguely tinged with brownish at center, subtriangular with apex shortly truncated. Surface minutely and sparsely punctured, with scarce, very short setae.</p> <p>Elytron usually yellow with large subrectangular black band along basal margin, occupying whole anterior fourth, leaving free only postscutellar area. Second transverse, slightly sinuous black band extended between midline and apical clivus. Further black spot, rising from latter, extended along suture, broadened onward and generally meeting the anterior black band. Suture along apical clivus narrowly black. Quite frequently black design less developed, with transversal bands fractioned into separate, roughly rounded spots, giving 4 + 1 + 3 pattern on total area of two elytra. More rarely, part of those spots missing or very small. Epipleuron yellow. Elytral outline short with sides almost straight and convergent posteriorly. Lateral margins narrow, simultaneously visible from above only along posterior half. Elytral surface slightly flattened on disc, moderately shiny with well-impressed punctation arranged in almost regular rows, distinct up to posterior clivus. Intervals flat. Postscutellar area fairly raised. Humeral callus prominent, impunctate. Epipleuron smooth, impunctate, with convex surface.</p> <p>Pygidium totally yellow. Surface matt, covered with close shallow punctures and appressed, pale setae.</p> <p>Ventral parts of thorax black usually with yellow spot on metasternum. Prosternal process spotted with yellow as well. Abdominal ventrites 1–4 black with yellow margins. Fifth abdominal ventrite almost completely yellow. Hypomera, mesepimera and mesepisterna almost bare, shiny, with scattered punctures. Remainder of ventral surface of thorax matt, covered with rather dense, short, regularly distributed setae and fine, shallow punctures. Prosternal process large, with sides almost straight between anterior coxae, then converging in large, round apex; surface anteriorly almost flat, then slightly concave toward apex, covered with coarse, shallow punctures and sparse, long, semi-erect setae. Legs totally light yellow.</p> <p>Median depression on fifth abdominal ventrite very shallow and hardly detectable, but with fewer setae and punctures than remainder of ventrite surface.Ventrite posterior margin very feebly notched. Median lobe of aedeagus (Fig. 5g –k) with apex bluntly terminated in almost straight line, with median short, acute denticle. Ventral outline marked with low, straight carina along nearly whole aedeagal shaft. Setose depressions narrow, shallow laterally, with surface covered by small punctures and long arcuate setae.</p> <p> <i>Female</i>. Habitus in Fig. 5a–b (LT). BL = 5.0– 5.8 mm, BW = 3.3–3.8 mm,
