    Lasiacantha aemula (Drake, 1947), nov. comb. (Fig. 7b) Tingis aemula Drake, 1947: 115 (sp. nov.); Drake and Ruhoff, 1965: 390 (catalogue); Cassis and Gross, 1995: 435 (catalogue). Holotype. ♀, AUSTRALIA: South Australia: Ooldea, 30°27’S 13150’ E, A. M. Lea (USNM, Drake collection). Dorsal habitus photo of type (Fig. 7b). Diagnosis. Lasiacantha aemula is recognised by the following combination of characters: broadly uniform colouration, with medium to dark brown band across costal area; major setiferous tubercles on pronotum and hemelytra very short, terminal seta subequal or longer than tuberculate base and mostly recurved, except for anteriorly on the paranota where straight; anterior margin of pronotum, keel of collum and pronotal carinae with major setiferous tubercles; costal area with setiferous tubercles extending halfway along hemelytral margin; carinate margins of discoidal area with major setiferous tubercles, posterior angle without clump of setiferous tubercles; head with flattened, elongate scalelike setae; pronotum with hairlike setae only, moderately elongate, weakly thickened; hemelytra with sparsely distributed hairlike setae at base, in subcostal and costal areas; cephalic spines greatly elongate, medial spine straight; AIV weakly clavate apically; collum subtriangular; carinae mostly uniseriate; paranota two areolae wide; costal area uniformly two areolae wide; subcostal area two areolae wide; areolae on paranota and costal area moderately small and uniformly round shaped; areolae in discoidal and subcostal areas subequal in size to areolae in sutural area. Host plant. Unknown. Distribution. Known only from the type locality at Ooldea (Oldea [sic] in original description (Drake 1947)) in southern South Australia, on the eastern edge of the Nullarbor Plain. Remarks. Lasiacantha aemula is most closely related to L. vittata, L. serraseta, and L. discordis, with all four species possessing a subtriangular collum, highly elevated pronotal carinae, and a brown band across the costal area of the hemelytra. It is very similar to L. vittata and L. serraseta (and all differing from L. discordis) in its overall uniformly reddish to pale brown colouration, smallish and uniformly sized areolae in the paranota and costal area, and all the areolae in the hemelytra are subequal in size. Lasiacantha aemula and L. serraseta have mostly uniseriate pronotal carinae, differing from L. discordis and L. vittata by the mostly biseriate pronotal carinae. However, L. aemula is easily distinguished from these three species by the paranota with two rows of areolae (rather than three rows in the other species; or sometimes biseriate in L. discordis with large irregularly shaped areolae), costal area uniformly biseriate with areolae moderately small and uniformly round shaped (triseriate in vittata and serraseta; mostly biseriate in discordis, but sometimes triseriate at widest point wide and cells mostly large and irregularly shaped), slightly more elongate discoidal area, and setiferous tubercles on posterior half of paranota, and costal area very short with recurved terminal setae (rather than all mostly very short and straight terminal setae). Also, the occipital cephalic spines in L. aemula do not appear to be as greatly elongate and curved as in the other related species. The recurved terminal setae on the setiferous tubercles in L. aemula is a putatively autapomorphic character for the Australian Lasiacantha species, however these recurved terminal setae are also present in one Inoma species, I. arrernte Cassis and Symonds.Published as part of Cassis, Gerasimos & Symonds, Celia, 2011, Systematics, biogeography and host plant associations of the lace bug genus Lasiacantha Stål in Australia (Insecta: Hemiptera: Heteroptera: Tingidae) 2818, pp. 1-63 in Zootaxa 2818 (1) on page 18, DOI: 10.11646/zootaxa.2818.1.1, http://zenodo.org/record/528906

    Megadrymus brigalow n. sp. (Figs 1 & 2) Holotype: &female;, AUSTRALIA: Queensland: 3 km S of Pine Mt, 21.77133 °S 148.8393 °E, 230 m, 24 Mar 2000, G. Monteith, ex. Malaise trap in vine scrub (AMNH _PBI 00399811) (QM). Diagnosis. Megadrymus brigalow n. sp. is distinguished by the following characters: very small size, <3.5 mm, ovate, robust body, general colour reddish brown, entire forefemora and apical three quarters of meso- and metafemora orange-brown, remainder of legs pale cream brown; corium with distinct patches of light cream and darker reddish brown; inner corium without distinct distal pale spot, only diffusely pale; posterior pronotal lobe pale overall; transparent (colourless) wing membrane; sparse distribution of very short simple setae on abdominal venter, denser laterally; middle of posterior pronotal lobe with v-shaped depression; tricarinate keel of pronotum removed from anterior margin of scutellum, scutellum strongly inclined anteriorly, keel without thickened anterior arms; prosternum slightly elevated but without longitudinal ridge between forecoxae; posterior lobe of metapleuron punctate; forefemur weakly incrassate, only with anteroventral row of spines, hind tarsi with 1 st tarsomere less than twice 2 nd and 3 rd together. Description. Female. COLOURATION. Head: dark reddish brown; labium cream, labial segment orangish. Antennae: orange-brown. Pronotum: explanate pronotal margins cream; anterior pronotal lobe uniformly redbrown; posterior pronotal lobe cream, with prominent red-brown v-shaped marking medially from anterior margin and two diffuse semi-circular orangey patches from posterior margin, punctations red-brown, posterolateral corners orange-brown. Scutellum: mostly red-brown, anterolateral corners slightly darker, lighter cream markings along posterolateral margins adjacent to clavus. Hemelytra: punctations red-brown; clavus orange-brown, cream dash posteriorly; corium banded, orange-brown basally, red-brown medially and apically, cream brown in between; inner third of corium without distal cream spot, just diffusely lightened; embolium cream basally, orangey distally; membrane transparent, no colour. Thoracic pleura and sterna: red-brown; posterior margins of pro- and metapleuron and supracoxal lobes slightly lighter orange-brown; scent gland evaporative area and peritreme dark brown. Legs: trochanters yellowish; coxae orange-brown; forefemur entirely orange-brown; mid and metafemora yellowish at base, apical three quarters orange-brown; tibiae and tarsi yellowish. Abdomen: red-brown. SURFACE AND VESTITURE. Punctation present over entire inner third of corium and most of outer third of corium, outer third with three rows of punctuations; antennal segments with moderate distribution of semi-erect setae, apical half of AIII +AIV also with short adpressed simple setae; abdominal venter with sparse distribution of short simple setae, denser laterally. STRUCTURE. Very small size, body length 3.37 mm; body shape ovate, robust. Head: length 0. 36 mm; width 0.75 mm; without bent or stepped gula; clypeus prominently elevated above mandibular plate; interoccular distance 0.47 mm. Pronotum: anterior pronotal lobe 0.47 mm long, 1.07 mm wide; posterior pronotal 0.40 mm long, 1.38 mm wide; anterior pronotal lobe a half longer than posterior pronotal lobe; latter 0.47 mm; anterior pronotal lobe moderately elevated; posterior pronotal lobe with medial depression from anterior margin. Scutellum: length 0.77 mm; tricarinate keel over posterior two thirds of scutellum, strongly elevated, anterior arms not thickened. Hemelytra: macropterous. Thoracic pleura and sterna: prosternum elevated medially; posterior section of metapleuron with row of punctations along posterior margin and on lateral margin. Forefemora: weakly incrassate; with one row of spines on ventral surface; anteroventral row of spines straight, major spine small, much shorter than width of tibia, directed straight; anteroventral margin not apically excavated/concave between major spine and apex; posteroventral swollen spine absent. Hind tarsi: 1 st tarsomere less than twice length of 2 nd and 3 rd tarsomeres combined. Remarks. We did not place this new species in Megadrymus (Cassis & Symonds 2012) based on its lack of a stepped gula; transparent wing membrane; scutellar keel being more weakly defined, without thickened anterior arms; presence of a v-shaped impression medially on the posterior pronotal lobe; forefemora with only one (anteroventral) row of spines and only very weakly incrassate; contrasting colouration on corium with very distinct patches of light and dark (whereas in other Megadrymus spp. edges between light and dark patches are more diffuse); lack of distinct and relatively large pale spot distally on inner corium; posterior pronotal lobe pale overall; clypeus prominently elevated above mandibular plate; hind tarsi with 1 st tarsomere less than twice 2 nd and 3 rd together. As a consequence M. brigalow n. sp. was placed sister to the clade of Paradrymus exilirostris Gross + Megadrymus, in our phylogenetic analysis (Cassis & Symonds 2012, see Figure 1). However, on re-examination of the specimen and more extensive study of Australian Drymini in collections, we have determined this species to be a member of Megadrymus. We have observed that within other Drymini, that with very small species many characters seem to be reduced in expression or absent compared to other seemingly congeneric morphospecies (i.e. shape of the head, pronotum and scutellum and structure of the forefemora), as seen also in Megadrymus brigalow n. sp. Megadrymus brigalow n. sp. is the smallest species in the genus and most atypical with respect to the pronotal and scutellar colouration and structure, and colouration of corium as described. In particular, colouration of the tricarinate keel of the scutellum is for the most part the same as the ground colour of the scutellum, as opposed to most other species of Megadrymus where the keel colouration is contrasting, being lighter in colouration. Megadrymus tenuicornis (Gross) is also very small (Female = 3.76 mm) and also more pale in colour but can be differentiated most easily by the shape of the pronotum and scutellum structure. Megadrymus brigalow n. sp. is similar to M. kakadu Cassis and Symonds, but differs by being smaller, and by having a more ovate and robust body shape (rather than the more slender shape of M. kakadu), and again the pronotal and scutellar structure. Setae on the abdominal venter of M. brigalow n. sp. are slightly shorter than in M. kakadu but with same distribution. In addition, M. brigalow n. sp. has the forefemora only weakly incrassate and without any outer swelling or spine, which we refer to as the posteroventral basal tumescence (see Figure 7, Cassis and Symonds 2012). Distribution. Megadrymus brigalow n. sp. is known from a single locality on the Great Dividing Range, southwest of Mackay on the mid coast of Queensland (See Figure 2). The specimen was collected from semievergreen vine thicket, a scattered dry rainforest habitat found in the Brigalow Belt (North and South) and Nandewar IBRA Bioregions (mapped in Figure 2), and nationally listed as an endangered ecological community, mainly due to loss and fragmentation from clearing and degradation of remnants (Department of the Environment 2013). Pine Mountain is located within the Brigalow Belt North IBRA Bioregion. Etymology. After the biogeographic region of the type locality.

    Silvia Pot&igrave;,1 Laura Palareti,1 Frederica RMY Cassis,2 Sonia Brondi11Department of Education Studies &ldquo;Giovanni Maria Bertin&rdquo;, University of Bologna, 40126 Bologna, Italy; 2Faculty of Medicine Clinics Hospital, University of S&atilde;o Paulo, S&atilde;o Paulo, SP, 05403-000, BrazilBackground: Assessing the viewpoints of health care professionals concerning their work with chronic patients is a relatively new research topic, widely overlooked in the literature. However, understanding their subjective work experience is highly relevant for identifying problems and perceived resources, enhancing health service organisation, improving relationships or communication with patients, and maintaining well-being.Purpose and method: Qualitative data from the &ldquo;Haemophilia Experience, Results and Opportunities&rdquo; Initiative &ndash; a research program aimed at investigating the psychosocial aspects of hemophilia &ndash; were used to evaluate the experiences of 62 professionals from seven countries around the world. Semi-structured interviews were submitted to thematic analysis of elementary contexts with the aid of T-Lab software.Results: Five dominant themes emerged, identifying the main challenges that professionals have to deal with in their everyday work practice: caring for impaired adult patients; handling policies and stakeholders; providing counselling on diagnosis and reproductive choices; considering the role of family dynamics; coping with adolescent patients.Conclusion: The outcomes of the study provide an opportunity to develop the area of the non-technical skills in the core curriculum of those who work with chronic illnesses by focusing on cross-professional competences and by improving a comprehensive care model for hemophilia patients.Keywords: health care professionals, subjective experience, chronic illness, hemophilia, cross-cultura

Remarks. Until recently, Emesopsis was diagnosed by the presence of a small, subquadrate basal cell in the forewing (Wygodzinsky 1966). This has since been shown not to be the case, with the recently described Australian mainland species E. infenestra Tatarnic Wall and Cassis, and now the Norfolk Island species E. cirratus, both shown to lack this trait. These species correspond in all other characters with the genus, prompting a revision of the diagnosis (Tatarnic et al. 2011). This species is also unique among congeners as the only one to exhibit any form of wing reduction.Published as part of Tatarnic, Nikolai J. & Cassis, Gerasimos, 2011, The thread-legged bugs (Hemiptera: Heteroptera: Reduviidae: Emesinae) of Lord Howe and Norfolk Islands, pp. 21-43 in Zootaxa 2967 on pages 32-35, DOI: 10.5281/zenodo.20700

The hairlike setae in this species are not as elongate as in other species with very fine, apically hooked, hairlike setae.&lt;/p&gt; &lt;p&gt; Additionally, the woolly setae on the head and pronotum is the same in the above two species, whereas in other Clade 3 species it tends to be slightly longer, less curly and more upright on pronotum than on the head. &lt;i&gt;Lasiacantha luritja&lt;/i&gt; fifth instar larvae can be distinguished from those of &lt;i&gt;L. aureolus&lt;/i&gt; as follows: overall colouration darker; dorsal processes are more greatly elongate, with a tapering apex, with moderate distribution of longer setiferous setae (these setiferous setae on dorsal processes in &lt;i&gt;L. aureolus&lt;/i&gt; are very sparse and very short), and marginal dorsal processes on pronotum and abdominal tergites being unicolourous&mdash;all dark brown.

However, it is only known from two specimens, and we regard this as a sitting record. It should be noted that Eremophila species were also sampled from the type locality, and although no specimens of L. quilpie were found on them, their sympatry with Frankenia at this site raises doubts about the authenticity of the host record. Distribution. Known from one locality in semi-arid, southwestern Queensland (Fig. 3a). Etymology. After the type locality. Remarks. Lasiacantha quilpie is most closely related to L. eremophila, but differs as follows: AI and base of femur being dark red brown, only orange brown in L. eremophila and not significantly darker than AII and AIII and rest of leg; collum much larger; cephalic spines greatly elongate; medial spine forked basally (rather than medially); occipital spines with a small dorsal branch; areolae in hemelytra and paranota larger than those in L. eremophila; and the costal area being only ever two areolae wide. This species is similar to L. eremophila by having rather dark dorsal colouration, thickened lateral carinae and patches of white microtrichiae on the hemelytra, which distinguish both from L. dysmikos.

Host plants. Host plant records are known only for W. viridimaculatus, which is known from two chenopod species. Mirids have been commonly collected from chenopods in arid and semi-arid Australia, with many of them new to science (Tatarnic & Cassis 2008). However, much of the chenopod-inhabiting mirid fauna, particularly new species belonging to the Orthotylini and Phylini are awaiting description. Remarks. The systematic position of Witchelinamiris is uncertain. On colouration characters the species shares some similarities with members of the Zanchius genus group (sensu Schuh 1974), with W. viridimaculatus sp. nov. having a green spotted dorsum. However, the head of both species of Witchelinamiris is elongate and the postocular margins are straight. In comparison, the head of members of the Zanchius genus group is short and not elongate in front, and the postocular margins are convex. In addition, the endosomal membrane is reduced, and both species have an elongate smooth endosomal spicule. The spicule structure differs considerably from Austromirini, typified by the Lattinova complex, which have two elongate spicules with limited endosomal membrane (Cassis 2008). It is also unlike examined Australian members of the Orthotylini, such as Harveycapsus (Cassis et al. 2010) and an undescribed genus of myrtaceaous inhabiting orthotylines (Cheng & Cassis in preparation), which have three endosomal spicules, which like austromirines have elongate spicules. Unlike these genera, the spicules of Witchelinamiris are smooth, and do not possess the sawlike margins of the spicules in the other abovementioned orthotylines. In addition, the parameres of both species of Witchelinamiris are distinctive, with the left paramere Cshaped with a small bifurcation at its apex, and the right paramere is simple, and is somewhat club-shaped. The female genitalia are simple, with the posterior wall of the genital chamber with simple paired processes that are unlike the inter-ramal lobes of other orthotylines (cf. Slater 1950; Cassis et al. 2010). Moreover, the opening of the vestibulum is symmetrical, which is akin to what is found in the Halticini (Tatarnic & Cassis in press) and species of the Hadronema complex (Forero 2008), and unlike asymmetry found in many Austromirini and Orthotylini. At present, it is difficult to assess the systematic position of Witchelinamiris because of the inadequacy of the tribal classification of the Orthotylinae. We tentatively place it within the Ortothylini pending further investigation and any future formalisation of the Zanchius genus group at the tribal level.Published as part of Namyatova, Anna A., Elias, Michael & Cassis, Gerasimos, 2011, A new genus and two new species of Orthotylinae (Hemiptera: Heteroptera: Miridae) from central Australia, pp. 38-48 in Zootaxa 2927 on pages 39-42, DOI: 10.5281/zenodo.27799

    CaSSIS color and multi-angular observations of Martian slope streaks

    No full text
    Slope streaks are albedo features that form frequently on equatorial Martian slopes. Most slope streaks are dark relative to surrounding terrains, a minor fraction is bright, and there are rare transitioning streaks that exhibit a contrast reversal partway downslope. Their formation mechanisms and physical surface properties are not well understood. New observations acquired by the Colour and Stereo Surface Imaging System (CaSSIS) on board ESA's ExoMars Trace Gas Orbiter (TGO) provide insights into slope streaks' surface microstructure, roughness and particle size ranges. Using multiple phase angle observations, we show that dark slope streaks are substantially rougher and possibly more porous than their bright counterparts, which are likely composed of more compact regolith. Color data acquired in the four wavelength bands suggest that dark streaks are spectrally similar to bright streaks but are composed of larger particles. The comparison of our orbital results to the laboratory measurements of Martian regolith analogs indicates that particles within dark slope streaks may be up to a factor of four larger than the granular material of the surrounding terrains. At one study site in Arabia Terra, using complementary imagery from other orbiters, we identify a case where dark slope streaks turned fully bright in a twenty-year period. These and CaSSIS observations suggest that bright slope streaks are old dark slope streaks, likely formed by deposition of dust or decomposition of surface aggregates into smaller particles

    Adetomyrma cassis sp. nov. (Figs 14, 15, 32, 41, 50, 67) Holotype. Male: CASENT0163620, BLF 24309: MADAGASCAR, Toamasina, Réserve Spéciale Ambatovaky, Sandrangato river, 16 ° 46.36´S, 49 ° 15.93´E, 450 m alt., rainforest, 4 Malaise traps, 20–24.ii. 2010, B.L.Fisher et al. [CASC] Worker and queen unknown. Male. Description. Measurements: holotype. HL 0.74, HW 1.08, SL 0.3, EL 0.43, WL 2.22, MnW 1.33, CI 144.8, SI 27.9, EI 58.1, MnI 123.8. Eye well-developed and prominent, posterior margin not exceeding posterior margin of mid ocellus in fullface view. Distance between lateral ocellus and eye long, about 3 × longer than diameter of lateral ocellus. Palpal formula 3,2? (three maxillary and two? labial: observed without dissection). Notaulus absent on mesoscutum (Fig 41). Parapsidal line clearly impressed. Anterior margin of petiole as long as dorsal margin in lateral view. Subpetiolar process well-developed, with dense hairs ventrally. Left and right parameres narrowly overlapping on dorsal small part of basimere (Figs 14, 15). Distinct, flattened projection present on each posterior portion of paramere with small denticles on distal and mesal portions of projection (Figs 14, 15). Hair on compound eyes long, longer than diameter of mid ocellus (Fig 50). Mesofemur in dorsal view with anterior face covered in dense, subdecumbent hairs. Ventral margin of eye edged with darker pigment but without minute punctures on the area. Body color almost uniform dark brown but head darker (Fig 32). Etymology. This species name is derived from the Latin word cassis (helm), and refers to the shape of its genital capsule, which looks like a Corinthian helm. The species epithet is treated as a noun in apposition, and thus invariant. Distribution. MADAGASCAR: as in Figure 67. Remarks. Adetomyrma cassis is only known from a single male collected in Réserve Spéciale Ambatovaky. The male of A. cassis is distinguished easily from other Adetomyrma males by a distinct and flatted projection on the posterior portion of the paramere (Fig 15). This projection is not separated from the paramere by a deep notch (Fig 14) as in A. bressleri (Fig 13). This genital character observed in Adetomyrma cassis is completely unique and sufficient to regard this male as a distinct species, although we have found neither another specimen nor sympatric distribution with other Adetomyrma species.Published as part of Yoshimura, Masashi & Fisher, Brian L., 2012, A revision of the Malagasy endemic genus Adetomyrma (Hymenoptera: Formicidae: Amblyoponinae), pp. 1-31 in Zootaxa 3341 (1) on page 19, DOI: 10.11646/zootaxa.3341.1.1, http://zenodo.org/record/21381
