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

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.

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.

The beginnings of pPhilosophy in Greece
No full textHow can we talk about the beginnings of philosophy today? How can we avoid the conventional opposition of mythology and the dawn of reason and instead explore the multiple styles of thought that emerged between them? In this acclaimed book, available in English for the first time, Maria Michela Sassi reconstructs the intellectual world of the early Greek “Presocratics” to provide a richer understanding of the roots of what used to be called “the Greek miracle.”
The beginnings of the long process leading to philosophy were characterized by intellectual diversity and geographic polycentrism. In the sixth and fifth centuries BC, between the Asian shores of Ionia and the Greek city-states of southern Italy, thinkers started to reflect on the cosmic order, elaborate doctrines on the soul, write in solemn Homeric meter, or, later, abandon poetry for an assertive prose. And yet the Presocratics, whether the Milesian natural thinkers, the rhapsode Xenophanes, the mathematician and “shaman” Pythagoras, the naturalist and seer Empedocles, the oracular Heraclitus, or the inspired Parmenides, all shared an approach to critical thinking that, by questioning traditional viewpoints, revolutionized knowledge.
A unique study that explores the full range of early Greek thinkers in the context of their worlds, the book also features a new introduction to the English edition in which the author discusses the latest scholarship on the subject

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>
