Description

Description. Males: Maximal length ca 50 mm, width of midbody PT 2.4 mm, 67 - 69 PT + telson. Body colour: uniformly white-yellowish, without particular coloration pattern; metazonites without posterior band. Head: uniformly white, cephalic suture visible. Antennae: long, extending beyond the posterior edge of PT 9 when folded backwards; antennomeres 2 - 5 light brown; 1, 6, 7 - white (Fig. 1); length of antennomeres: 1 - 0.3 mm, 2 - 1.4 mm, 3 - 1.8 mm, 4 - 1.2 mm, 5 - 1.3 mm, 6 - 0.7 mm, 7 - 0.4 mm; antennomere ratio: 3> 2> 5> 4> 6> 7> 1; tip of antennomere 7 with four cones protruding beyond posterior margin (Fig. 2). Eyes: black, well delineated, composed of 33 ocelli in 5 rows (Fig. 3). Width of PT 2 = 3 <1 = 4 <5 <6 <7. PT higher than broad, ratio: 1.05: 1. Dorsal side of collum and PT 2 - 3 smooth, lateral sides ribbed. Crests poorly developed, broad and flattened anteriorly, abruptly narrowing and more pronounced posteriorly; 5 + 5 between the ozopores on midbody PT. Ozopores small, barely visible on most PT, lying between crests 5 and 6 in midbody PT. Paraprocts divided into smaller dorsal and larger ventral sclerites. Dorsal sclerite surmounted with two macrosetae in a vertical row. Spinnerets: long and slender, ending with a long seta. All legs white-yellowish, long and slender, ending with a long claw. Tarsal pads very poorly developed, present on leg-pairs 3 - 12. No particular modifications on coxae of pregonopodal legs, prefemora of legs 4 - 7 swollen. Leg-pair 9 (Figs 4, 26): coxa subtrapezoidal; trochanter expanded medio-ventrad forming a rather elongated process (h) with a pointed tip and a smaller process z. Chaetotaxy: unknown, all setae broken off. Gonopods (Fig. 5): similar to those of congeners; coxae (cx): process g moderately large and swollen, ca 1.5 times the length of process k; processes g and k apically rounded, not truncated as in Sinocallipus jaegeri. Femoroid (fe): with three slender, acicular (n), and one short and subfalcate (m) terminal projections. Cannula (ca): long, and slender, not coiled. Female: unknown.
