Description

Length of holotype ca 4.1 mm, width (maximum on tergum 2) ca 1.8 mm; length of paratypes ca 4.0-4.3 mm, width on tergum 2 ca 1.8-2.0 mm, or 4.3-5.0 and 2.0-2.6 mm in males and females, respectively. Body entirely pallid (Fig. 3).

Ocelli ca 6+1, convex, completely translucid, poorly discernible (Fig. 3). Tömösváry’s organ pallid, transverse-oval, ca 1.4-1.5 times wider than long. Antennomere 6 rather long, ca 2.1-2.2 times as long as high.

Collum with two transverse striae. Tergum 2 with a narrow hyposchism extending behind to reach the caudal tergal margin; 6-7 superficial transverse striae, two starting below schism, one level with, all others above schism, with only one (never last one from below) crossing the dorsum. Male anal shield regularly rounded at caudal margin.

Male leg 17 (Fig. 4a) with a rather low, regularly rounded, outer coxal lobe; telopodite 3-segmented, tarsus with two strong apical spines.

Male leg 18 (Fig. 4b) with a narrow syncoxital notch; telopodite 4-segmented, tarsus with one apical spine.

Telopods (Fig. 4c, d) with a medium-sized, regularly rounded, central syncoxital lobe flanked by two setose horns, each latter clearly higher than central lobe and crowned by a small, elongate membranous lobule devoid of adjacent structures. Prefemur and, to a lesser extent and only parabasally, femur micropapillate laterally. Caudomedial femoral process prominent, directed distomedially at ca 100 º to femur, mostly strongly chitinized, only apically with a small membranous sac, on caudal face slightly setose. Caudomedial process of tibia evident, sac-shaped, membranous, at base with an evident, parabasally poorly setose tubercle on caudal face. Tarsus rather strongly curved, subacuminate apically.

Diagnosis

Differs from congeners in a completely unpigmented body, coupled with a rather long antennomere 6 which is ca 2.1-2.2 times as long as high, as well as by a narrow hyposchism which only reaches the caudal margin of tergum 2, 6-7 transverse striae of which only 1-2 cross the dorsum on tergum 2, a 3-segmented male telopodite 17, and a caudally slightly setose distomesal process of the telopod femur.

Etymology

To emphasize the fully unpigmented, translucid body. An adjective.

Taxon discussion

Due to such a clearly troglomorphic feature as the completely unpigmented body, this species may prove to be a troglobite.
