Description.
Female. (Figs. 31–38). Dimensions. Idiosoma: length 585; width 405 (fairly distended); length hypognathum 312; width hypognathum 119; length palp 323; length chelicera 262; length gnathosoma 470; length legs: I 443, II 385, III 447–450, IV 497–501; length sensillae vi approximately 270, sce 250; ovum 146 x 216.
Dorsum (Fig. 31). The reticulate propodosomal shield (Fig. 31 a) carries four pairs of setal structures: the two pairs of sensillae vi and sce (Figs 31 b & c) and the st-setae ve and sci. Distance sci-sci smaller than sci-sce. Setae ve very close to sce; the length of the latter are less than half the distance between them. Two small lateral hysterosomal “shields”. Except for setae f2 the usual pairs of hysterosomal setae are present; setae h1 longest, followed by f1. Other setae all about equal length.
Venter (Fig. 32). The venter of this specimen is torn. The venter is normal for the genus. The genito-anal region (Fig. 32) carries 4 pairs of g- setae on the genital valves with g3 laterad to line g1 - g2 - g4, one pair of anal setae on anal valves, one pair of para-anal setae and 1 pair of cupules ih on the integument between the two regions. A paragenital seta occurs laterad to each genital valve.
Gnathosoma (Figs. 33–35). The gnathosomal components are very much extended as compared to those of Dactyloscirus condylus Den Heyer, 1979.
Hypognathum (Fig. 33). Ratio length: width of the hypognathum is 2.9:1.
Palp (Fig. 34). The palp chaetotaxy is: trochanter 0, basi- and telofemur 1 dorsal spine-like seta each, telofemur also with a median small apophysis, genu with a small median apophysis, 2 sts and a distal spine, tibiotarsus with 1 ventromedian seta, 1 tubercle, 2 small setae, 1 terminal solenidion and a terminal claw.
Chelicerae (Fig. 35). This structure is nearly needle-like. Proximodorsal region of segment II with papillae in reticulate pattern. Segment I with random papillae.
Legs (Figs. 36–38) Tibiae I nearly twice the length of genua I. Leg setae vary from thin sts to stout macrosetae. Leg chaetotaxy: coxae I– IV 3 sts, 1 peg – 2 – 3 – 2 sts; trochanters I–IV 1 – 1 – 2 – 1 sts; basifemora I–IV 5 – 5 – 3 – 2; telofemora I–IV 5 – 5 – 4 – 4; genua I–IV 2 asl (very close but not duplex), 1 asl, {asl, 1 sts} 4 sts – 2 asl, 5 stout sts – 1asl, 1 stout ms, 4 stout sts – 2 asl, 5 sts (almost all stout); tibiae I – IV {1 asl, 1 sts}, 1asl, 4 sts – 1 bsl, 5 sts – 1 bsl, 5 sts (all stout) – 1T, 4 sts(3 of these stout); tarsi I – IV 3 asl, {1 bsl, 1 sts, 1fmls}, 1 dtsl, 2 tsl, 18 sts (of which 3 are spinose and situated ventrally on the anteromedian aspect) – 1 bsl, 1 dtsl, 1 tsl, 21 sts – 1 tsl, 21 sts – 20 sts.
Remarks. This species closely resembles Dactyloscirus smileyi Swift, 1996 with relation to size and other aspects. Differences, however, are given in Table 3.
