Description

Description. Males: Maximal length: ca 54 - 55 mm, width of midbody PT 2.5 mm, 67 - 71 PT + telson. Body colour: generally white-yellowish; head and PT 1 - 4 white, remaining PT mottled light brown-grayish, the last 1 / 5 of the body brownish; metazonites with a narrow transverse posterior band. Head: white-yellowish, pilose; epicranium marbled light brown; cephalic suture visible. Antennae: moderately long, extending beyond the posterior edge of PT 7 when folded backwards; antennomeres 1 and 7 white, 2 - 6 - brown; length of antennomeres: 1 - 0.4 mm, 2 - 1.1 mm, 3 - 1.3 mm, 4 - 0.8 mm, 5 - 0.9 mm, 6 - 0.7 mm, 7 - 0.3 mm; antennomere ratio: 3> 2> 5> 4> 6> 1> 7; tip of antennomere 7 with four cones protruding well beyond the edge. Eyes: black, well delineated, composed of 33 - 35 ocelli in 5 rows (Fig. 20). Width of PT: 2 - 3 <1 = 4 <5 <6 <7 <8 <9 <10. PT slightly higher than broad; ratio: 1.07: 1. Dorsal side of collum and PT 2 - 3 smooth, ribbed only laterally; complete crests series appearing from PT 4 onwards. Midbody PT with 3 + 3 crests between ozopores; no secondary crest series, all crests flattened, almost equally broad along the metazonal length, only slightly narrowed posteriorly and touching each other anteriorly. Ozopores on midbody PT lying between crests 3 and 4, visible from sixth to last but two PT. Paraprocts divided into smaller dorsal and bigger ventral sclerites. Each dorsal sclerite with a pair of macrosetae in a vertical line. Spinnerets: long and slender, ending with a long seta each. All setae on telson dark brown, contrasting with the whitish background. All legs white-yellowish, moderately long and slender, ending with a long claw. Tarsal pads poorly developed, present only on leg-pairs 3 - 12. No particular modifications on coxae of pregonopodal legs. Prefemora of legs 4 - 7 swollen. Leg-pair 9 (Figs 21, 29): coxa subtrapezoidal; trochanter with two processes: anterior one (h) higher, leaf-shaped, its tip very sharpened, spine-like, curved cephalad; posterior process (z) rounded with a small triangular bulge; a small pore opening (p) below the bulge. Chaetotaxy: pleurotergal setae barely visible, minute, one each on PT 1 and 2, others presumably broken off. Gonopods (Figs 22, 23): similar to those of congeners, but process k is longer. Coxae (cx): process g laterally narrowed, not clavate as in the other congeners; apical part slighly truncated (in lateral view); k 2 / 3 the height of process g, slightly bent lateralwards at midlength; apex with a small hook pointing towards process g. Femoroid (fe): with three slender, acicular (n), and one shorter and subfalcate (m) terminal projections, latter almost half length of the longest projection. Cannula (ca): long and slender, not coiled, its distal part lying between processes h and z on trochanter of leg 9 in close proximity to the pore opening (p). Female: unknown.
