Glyphiulus obliteratoides View in CoL n. sp. ( Figs 9-11 View FIG View FIG View FIG )
TYPE MATERIAL. — China. Ghizhou Prov. , Anshun County, Luangshuijing , Tian Xian Dong Cave (aquatic), 22.II.2004, leg. S. Prevorčnik & B. Sket, holotype ♂ ( MNHN GA 047 About MNHN ) ; paratypes 1 ♂, 1 ♀, 4 juvs ( MNHN GA 047 About MNHN ) ; 1 ♂, 1 ♀, 2 juvs ( ZMUM) ; 1 ♀ ( OBBFUL) ; 1 ♀ ( SEM) ; 1 subad. ♀ ( ZMUC). — Same cave , 23.II.2004, leg. B. Sket & S. Prevorčnik, 1 juv. ( OBBFUL) .
ETYMOLOGY. — To emphasize the very close resemblance to G. obliteratus n. sp.
DIAGNOSIS. — Differs from congeners by the pigmented ocelli and body, coupled with the more distinctly undulate collum, the undivided crests, etc. (see also key below).
DESCRIPTION
Holotype with 59p+1a+ T, about 32 mm long and 1.9 mm wide; adult paratypes (♂, ♀) with 45-60p+2- 1a+ T, length 22-35 mm, width 1.3-1.9 mm.
Coloration entirely pallid in young juvenile stadia, becoming marbled red-brown in adults, tergal crests dark castaneous brown; antennae, legs and venter light red-brown in adults. Adults with 7-9 blackish ocelli in a subtriangular eye patch.
Antennal sensilla, segment shape ( Fig. 10B View FIG ), tergal crests (including ozoporiferous ones) ( Figs 9 View FIG ; 10B View FIG ), epiproct ( Fig. 9E, F View FIG ), paraprocts ( Fig. 9E View FIG ), male legs 2 and 3 ( Fig. 11D, E View FIG ), penes ( Fig. 11D View FIG ), gonopods ( Fig. 11G, H View FIG ) generally as in G. obliteratus n. sp., but antennae ( Figs 9A View FIG ; 11A View FIG ) slightly shorter, gnathochilarium (mentum divided, n = 3) ( Fig. 11B View FIG ) more polytrichous; collum ( Fig. 9A, B View FIG ) with 1a-4a+ma+4a-1a undulations at caudal margin, undulation ma being shortest; hypoproct ( Fig. 10A View FIG ) very faintly emarginate caudomedially, conspicuous pleurosternal crests on segments 2-4 wanting ( Fig. 9A View FIG ); tergal crests similarly low and undivided, even adding another lateral crest below ozoporiferous one, which is barely traceable as a low anterior tubercle, but anterior end of all dorsal crests broadened ( Fig. 9 View FIG ); carinotaxy pattern thus 1/0+1+I/i+3+I/i+1+1/0 ( Figs 9C, D View FIG ; 10B View FIG ); a small accessory spine present at base of claw on legs 2 and 3 only ( Fig. 11D View FIG ), onward nearly missing ( Figs 10B View FIG ; 11F View FIG ); legs about as long as body diameter ( Fig. 10B View FIG ); male leg 1 with 5-segmented but shortened telopodites ( Fig. 11C View FIG ).
Head width = segment 2 = 6 <collum = 7(8)> segment 3 = 5 <7 <8 <9 <10 <11 = midbody segments; body gradually tapering toward telson. Postcollar constriction evident ( Fig. 9B View FIG ).
REMARKS
The samples contain five haplopodous juveniles with 30-33p+1-3a+T, each with the ozoporiferous tubercles fully developed only on segments 5 and 6. In general, even juveniles of later, diplopodous, stadia are easily recognised due to the ozoporiferous cones being especially well developed on segments 5 and 6 only.
In the absence of any troglomorphic traits, this species can only be considered troglophilic at most.
