Name: To emphasize the provenance of material from caves in the High Kabylia, Algeria.
Diagnosis: Differs from all congeners except G. albida Mauriès & Vicente, 1978 and G. monostriata sp. n. in the clear troglomorphy (in particular, the lack of pigmentation), coupled with two striae crossing the collum and 1-2 striae crossing the thoracic shield, and usually with (6)7+1 ocelli.
Description: Length of extended adults of both sexes ranging between 13.5-14.0 (♁) and 15.0- 17.5 mm (♀), width 3.4-4.2 (♁) and 5.0- 5.8 mm (♀), body broadest at thoracic shield. Holotype ca 13.5 mm long and 3.65 mm wide (extended), or ca 9.5 and 3.5 mm, respectively (unextended). Juveniles with 12 segments (like adults) and 5 ocelli, ca 4.8 mm long and 2.2 mm wide. Juveniles with 11 segments and 5 ocelli, ca 4.5 mm long and 2.2 mm wide. Juveniles with 10 segments and 3 ocelli, ca 3.4 mm long and 1.75 mm wide. Juveniles with 8 or 9 segments and 2-3 ocelli, ca 2.7-2.8 mm long and 1.13-1.40 mm wide.
Coloration entirely pallid.
Head usual, transverse; Tömösváry’s organ transversely oval, strongly elongate ( Fig. 1A View Figure 1 ); antennae long, antennomere 6 longest, 2.5-2.8 times longer than wide ( Fig. 1B View Figure 1 ); ocelli usually 7+1, rather convex but usually transparent and thus poorly visible ( Fig. 1A View Figure 1 ), only rarely pigmented (5+1 or 6+1 grey ocelli in ♁♁ from Anou Tahalouant and n’Tarzout caves, respectively).
Collum with two transverse striae.
Thoracic shield with a narrow hyposchism reaching the caudal tergal contour ( Fig. 1C View Figure 1 ); 3-4 transverse striae, of which 1-2 anterior, starting well in front of schism, crossing entire dorsum, while the others, starting just above schism, are abbreviated ( Fig. 1C View Figure 1 ).
Tergal surface very finely punctate. Terga 3 and 4 rather broadly rounded laterally, tergum 3 being only slightly narrower ( Fig. 1C View Figure 1 ). Tergal pilosity and mid-dorsal sinuosity lacking. Pygidium usually with a completely regularly rounded caudal margin, only rarely extremely faintly sinuated medially at margin.
♁ leg 17 ( Fig. 1D View Figure 1 ) with a medium-sized, regularly rounded, outer coxal lobe; telopodite 4-segmented.
♁ leg 18 ( Fig. 1E View Figure 1 ) with a broadly ogival syncoxital notch; telopodite 4-segmented.
Telopods ( Figs 1F, G View Figure 1 ) with a rather high, regularly rounded, bare, central syncoxital lobe flanked by two setose horns, each crowned with a very small bulb and a long, setiform filament. Femur with a large caudomedial outgrowth, subquadrate at base. Tibia with a caudomedial unciform process. Tarsus rather broadly rounded apically.
Remarks: This species is the only clearly troglomorphic congener to be reported from Algeria. It is noteworthy that some specimens show rudimentary pigmentation of the ocelli.
Based on the shape of tergum 3, this new species can be regarded as somewhat intermediate between the “ Stenopleuromeris ” and “ Eurypleuromeris ” types, although closer to the former.
