( Figs 30–34 View FIGURE 30 View FIGURE 31 View FIGURE 32 View FIGURE 33 View FIGURE 34 )
Adult male
Idiosoma elongate, slightly narrowed between bases of legs III and IV; length 550 µm, maximum width 315 µm. Sejugal furrow clearly evident, hysteronotum about twice as long as prodosum ( Fig. 30 View FIGURE 30 ).
Prodorsum. About two-thirds as long (160 µm) as wide (250 µm). Prodorsal plate much longer (185 µm) than wide (125 µm), extending anteriorly beyond anterior edge of propodosoma, with 27 lanceolate setae on each side, anteriormost pair 40 µm long, posteriormost pair 32 µm long. Crista metopica linear, rod-like, 140 µm long, widest anteriorly, ca 7 µm. A pair of lanceolate setae (40 µm) posterolateral to prodorsal plate, each on a platelet. A pair of posterolateral plate each bearing 9 setae of ca 35–40 µm long. Eyes absent.
Hysterosomal dorsum. Hysterosoma with traces of segmentation, each with large lateral plates bearing several to numerous setae.
C row with medial setae each on a platelet, but lateral setae clustered on a pair of large plates; setae 32–40 µm long, all lanceolate.
D row with medial setae (30–35 µm long) each on a platelet, a pair of sublateral plates each with 3 setae (32–40 µm long) and a pair of lateral plates each with 11–12 setae (35–40 µm long).
E row with a pair of lateral plates each with 8 lanceolate setae (35–40 µm long) and numerous lanceolate setae each on a platelet between them (a couple of them have joined platelets) and also a few lateral to them above trochanter III.
F row with similar setal and plate arrangement as in E, but only several setae between the pair of large plates.
H row with a pair of lateral plates each with 18 setae and about 12 setae between them each on a platelet.
PS row with a pair of large plates each bearing numerous lanceolate setae mostly 50 µm long; the pair of plates ventrally touching each other.
Idiosomal venter. Intercoxal area of leg I with 4 short setae (20–34 µm long; posterolateral pair 1a 25 µm long, on its own platelet). Intercoxal area of leg II with 3–4 pairs of setae on a pair of plates. Intercoxal area of leg III with 6 pairs of setae and that of leg IV with several numerous setae not separable from those anterior to genital area. Coxal I with 13–15 setae. Coxa II with 14 setae. Coxa III with 9 setae. Coxa IV with 8–9 setae. Opisthoventer with a large plate enclosing anus and genital area (240 µm long and180 µm wide), with numerous short setiform setae similar to coxal setae. Genital opening 78 µm long. A pair of central valves each bearing 7–8 setae, anterior and posterior ones setiform, but median 3 pairs thickened and branched distally. A pair of lateral valves each bearing 8–9 setae of similar size (up to 20 µm long). Five pairs of eugenital setae, all nude, setiform, the posterior three pairs relatively close together ( Fig. 33 View FIGURE 33 B). Anal opening 85 µm long, its valves each with a pair of setae.
Legs. Length of legs in decreasing order: leg I> leg IV> leg III> leg II.
