Glyphiulus parobliteratus View in CoL n. sp.

( Figs 12 View FIG ; 13 View FIG )

TYPE MATERIAL. — China. Guizhou Prov., Zhuanyankong, 107°18’55.0”E, 28°14’30.9”N, emergence porch, 750 m,

1.III.2003, leg. M. Pouilly (CHI-Pouilly4), holotype ♂ ( MNHN GA 048).

OTHER MATERIAL. — China. Guizhou Prov., Shuanghe River, Wenquan, Dafen Dong Cave, 107°18’44”E, 28°14’25.4”N, 680 m, 20.II.2003, leg. M. Pouilly (CHI-Pouilly6), 1 ♂ ( MNHN GA 048).

ETYMOLOGY. — To again emphasize the very close resemblance to G. obliteratus n. sp.

DIAGNOSIS. — Differs from congeners by the unpigmented ocelli, coupled with the particularly polytrichous gnathochilarium, as well as certain details of gonopod structure (see also key below).

DESCRIPTION

Holotype with 41p+5a+ T, about 26 mm long and 1.3 mm wide; non-type ♂ with 44p+5a+ T, length about 22 mm, width 1.2 mm.

Coloration light grey-brown with contrastingly dark brown ozoporiferous cones, with head, antennae, legs and venter light yellow-brown (holotype), or rather uniformly dark grey-brown to brown (nontype). Ocelli barely discernible as slightly convex tubercles, unpigmented, two or three in eye patch on each side of head.

Antennae ( Fig. 13A View FIG ), collum with 1a-4a+ma+4a- 1a undulations at caudal margin, undulation ma being shortest ( Fig. 12A View FIG ), tergal crests (including ozoporiferous ones) ( Fig. 12B, C View FIG ), postcollar constriction, telson, segment shape ( Fig. 12B View FIG ), male legs 2 and 3 ( Fig. 13D, E View FIG ), other legs ( Figs 12B View FIG ; 13F View FIG ) generally as in G. obliteratus n. sp., but gnathochilarium (mentum divided, n = 2) ( Fig. 13B View FIG ) even more polytrichous; conspicuous pleurosternal crests on segments 2-4 wanting ( Fig. 9A View FIG ); tergal crests divided, second lateral crest below ozoporiferous one barely traceable as a low anterior tubercle, carinotaxy pattern thus 1/0+1+I/i+3/3+I/i+1+1/0 ( Fig. 12B, C View FIG ); legs slightly longer than body diameter ( Fig. 12B View FIG ); male leg 1 with 5-segmented, normal telopodites ( Fig. 13C View FIG ).

Anterior gonopod coxosternum ( Fig. 13G View FIG ) with still longer paramedian processes. Posterior gonopods ( Fig. 13H View FIG ) with long, distally plumose flagella.

REMARKS

Because the non-type ♂ shows some minor differences from the holotype – the slightly better developed crests on the collum and subsequent terga, thus showing two crests, not one, below the ozoporiferous cones – the conspecificity of these samples remains to be verified.

Such troglomorphic traits as the unpigmented ocelli and the elongated appendages allow this species to be considered as troglobitic.
