Maddison, Agnarsson, Iturralde, Salazar, WPM#04–032 (UBC-SEM AR00149). Etymology. Latin adjective foliosus (leafy), referring to the leaf-like marking on the dorsum of the abdomen. Diagnosis. Similar to Ilargus macrocornis in the color and marking patterns, and the presence of guanine deposit in the eye area (Figs 53–54), but differs in the absence of a spur on the front surface of the male chelicera.

Embolus long with a relatively wide spiral; proximal tegular lobe large; retrolateral sperm duct loop occupying more than half of bulb width; retrolateral tibial apophysis finger-like; ventral tibial bump absent. Measurements of legs: I 3.3, II 2.9, III 3.4, IV 3.6. Color in alcohol (Fig. 53): carapace dark brown, eye area with guanine deposit, behind eye area with a medial and two marginal yellowish stripes; abdomen dark brown, with many silvery white speckles and a large leaf-like mark medially; legs yellowish to dark brown. Female (paratype, UBC-SEM AR00149). Carapace length 1.4; abdomen length 1.8. Chelicera (Fig. 57): red brown. Measurements of legs: I 2.4, II 2.2, III 2.6, IV 3.2.

Paratype: 1♀ (UBCZ; KYU-SAL451), same data as holotype. Other material examined. 3♁ (UBCZ; KYU-SAL452), same data as holotype. Etymology. The specific epithet is from Malay, meaning “burnt”, corresponding to the color of the new species that looks like it has been burned. Diagnosis. It can be recognized from other congeners of daiqini -group by its dark color (Figs 70–74). The male can be distinguished from all other congeners by the S-shaped embolus (Fig. 80; vs. not S-shaped in other species). The female resembles C. logunovi sp. nov. by the relatively short copulatory ducts, but it can be distinguished by the relatively low turning point of copulatory ducts which is close to the spermathecae (Fig. 83; vs. the turning point is at the median part of copulatory ducts in C. logunovi sp. nov.).

Confocal quality imaging of afferent neurons from semi-thin sections of Drosophila ganglia
No full textThe aim of this study was to develop protocols for computer imaging of the thoraco-abdominal ganglion of Drosophila from serial semi-thin sections, in which specific neurons were stained and related to neuropilar structures. The central projections of a subset of transgenically labelled sensory neurons were revealed by immunohistochemistry, while Nomarski optics were used to show motor neuron targets in the neuropil. Digital photomicrographs of each section were aligned and the resultant image stacks rendered into three-dimensional (3D) images that can be rotated in real time. The result is a detailed, in-depth visualization of labelled neurons at a resolution comparable with that in confocal reconstructions, which also allows investigation of their relationships with other components of the neuropil.<br/

No full textLapsias lorax Maddison, 2012 Figs 32–39, 57 Lapsias lorax Maddison, 2012: 53, figs 2–8 (male holotype from Bellavista Cloud Forest Reserve, Pichincha, Ecuador, deposited in QCAZ, not examined); WSC, 2022. Diagnosis. The placement of the embolus (e), tegular apophysis (Ta) and median apophysis toward the distal tip of the palp is more extreme in L. lorax that in other Lapsias species (Maddison 2006). Males recorded from Colombia (Quindio) do not present the yellow bars across the chelicerae. Females can be recognized by the semirounded spermathecae (sp) placed posteriorly, the short and lateral copulatory ducts (cd), the anterior copulatory openings (co), and the long overhanging projection that arise in the anterior edge of the epigynal plate and exceed the posterior edge.

Epigynum (Figs 36–39) with copulatory openings (co) in a single anterior oval cavity, overhanging lobe that exceed the posterior margin of the epigynal plate and arises in the upper side of the cavity, short copulatory ducts (cd) and semirounded spermathecae (sp) placed posteriorly. Variation. (n= 2 females) Total length 6.00–3.60. Carapace length 2.33–1.77. Distribution and Comments. Ecuador (Pichincha) (Maddison 2012). New record from Colombia (Quindío) (Fig. 57). The specimens were collected in a well-conserved high Andean ecosystem.Published as part of Muñoz-Charry, Valentina, Galvis, William & Martínez, Leonel, 2022, Jumping spiders of the tribe Lapsiini Maddison (Salticidae: Spartaeinae) from Colombia: new species and records, pp. 356-373 in Zootaxa 5129 (3) on pages 365-366, DOI: 10.11646/zootaxa.5129.3.2, http://zenodo.org/record/650112

Females can be distinguished by the relatively large atria and the slightly rounded spermathecae (Figs 35–36).</p> <p> <b>Description. Male.</b> Habitus as shown in Fig. 29. Measurements of holotype (KYU-SAL401): carapace 1.80 long; abdomen 1.86 long; measurements of eyes: AME 0.40, ALE 0.26, PME 0.08, PLE 0.21; measurements of legs: I 3.58 (1.07, 0.79, 0.81, 0.53, 0.38), II 2.59 (0.85, 0.39, 0.52, 0.48, 0.35), III 2.67 (0.94, 0.44, 0.41, 0.59, 0.29), IV 3.08 (0.98, 0.49, 0.60, 0.67, 0.34); leg formula 1432. Endite with anterior lateral subtriangular extension. Color in ethanol (Fig. 29): Body dark, covered with dense khaki setae except for face, palp and tibia I, these parts conspicuously black compared to other body parts; dorsal abdomen with indistinct hollow longitudinal light mark on axis, and three pairs of light setal bands on each side of posterior part (Fig. 29).</p> <p>Palp as in Figs 33–34, 37–38: Cymbium slightly longer than palpal bulb, cymbial process (CyP) present, slightly visible in ventral view of palp; tegular lobe wide and stout, distal part prolaterally pointed; short embolus sticking out of large and oblong embolic disc which hidden behind bulb, with retrolateral distal hump (RdH); small apical extension of embolus (aE) sticking out of wide and deep groove around itself; retrolateral tibial apophysis (RTA) straight, distal part digitiform.</p> <p> <b>Female.</b> Habitus as shown in Fig. 30. Measurements of paratype (KYU-SAL402): carapace length 1.74; abdomen length 1.86; measurements of eyes: AME 0.37, ALE 0.25, PME 0.06, PLE 0.21; measurements of legs: I 2.57 (0.81, 0.48, 0.52, 0.38, 0.38), II 2.36 (0.79, 0.36, 0.47, 0.41, 0.33), III 2.54 (0.78, 0.42, 0.41, 0.53, 0.40), IV 3.00 (0.98, 0.48, 0.56, 0.63, 0.35); leg formula 4132.
