Length of holotype ca 5.5 mm, width (maximum on tergum 2) ca 2.5 mm; length of paratypes ca 5.0-6.0 mm, width on tergum 2 ca 2.1-3.0 mm, or males and females, respectively. Body from nearly entirely pallid (especially so in smaller specimens) to coloration remnants persisting on head and terga (Fig. 1a, b, c). Head usually with a considerably infuscate, large, brownish to blackish patch around Tömösváry’s organ and ocelli each side (Fig. 1b, c), antennae pallid to very faintly brownish yellow. Trunk from entirely pallid to very faintly brown or grey-brown, in the latter case with a peculiar pattern (Fig. 1a, b, c). Collum very slightly marbled brownish on sides and with a rather wide, light brownish, subcaudal band in front of a narrowly flavous caudal margin (Fig. 1a, b). Tergum 2 (= thoracic shield) with a similar pattern, but subcaudal band wider, slightly broadened and remaining only above schism laterally while central part subtriangular and extending nearly up to front margin (Fig. 1a, b, c). Following terga with a similar pattern as well, each with a paramedian pair of large, transversely oval, flavous, sublateral, anterior spots above broadly flavous lateral margin. Last tergum (= pygidium) nearly entirely and uniformly light brown or grey-brown, with a broad flavous band at caudal margin (Fig. 1a, b, c). Ocelli 5+1 or 6+1, convex, completely translucid, but mostly clearly discernible due to an infuscated nearby background (Fig. 1b, c). Tömösváry’s organ pallid, transverse-oval, ca 1.4 times wider than long. Antennomere 6 rather long, ca 2.0–2.1 times as long as high. Collum with two transverse striae. Tergum 2 with a narrow hyposchism extending behind to reach the caudal tergal margin; 7-8 superficial transverse striae, only one starting below schism, one level with, all others above schism while three (never last one from below) crossing the dorsum. Male anal shield regularly rounded at caudal margin. Male leg 17 (Fig. 2a) with a rather high, regularly rounded, outer coxal lobe; telopodite 4-segmented, tarsus with three strong apical spines. Male leg 18 (Fig. 2b) with a regularly rounded syncoxital notch; telopodite 4-segmented, tarsus with one apical spine. Male legs 19, or telopods (Fig. 2c), with a high, regularly rounded, central syncoxital lobe flanked by two setose horns, each latter only slightly higher than central lobe and crowned by a minute, elongate, acuminate, 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 100º to femur, mostly strongly chitinized, only apically with a small membranous sac, but devoid of any chitinized lobe. Caudomedial process of tibia evident, sac-shaped, membranous, with an evident, rounded tubercle on caudal face at base. Tarsus rather strongly curved, subacuminate apically.

Differs from congeners in a partly to completely unpigmented body, coupled with sometimes still persisting remnants of a peculiar colour pattern, a rather long antennomere 6 which is ca 2.0–2.1 times as long as high, as well as by a narrow hyposchism which only reaches the caudal margin of tergum 2, and 7-8 transverse striae of which three cross the dorsum on tergum 2. Differs clearly from all known Greek congeners, including two new ones described below, also by a 4-segmented male telopodite 17 (Fig. 2a).

To emphasize the nearly fully to fully reduced body coloration similar to the condition observed in the southern Chinese cavernicole, H. reducta Golovatch, Geoffroy & Mauriès, 2006. An adjective.

Due to such a troglomorphic feature as the completely or nearly completely unpigmented body, this species may well prove to be a troglobite. This cave on Chios is known to harbour at least one more endemic troglobite, the false-scorpion Chthonius chius Schawaller, 1990 (Pseudoscorpiones, Chthoniidae) (Harvey 2008).

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 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 100º 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.

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.

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

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

Length of holotype ca 6.0 mm, width (maximum on tergum 2) ca 3.0 mm; length of paratypes ca 6.0-6.2 mm, width on tergum 2 ca 3.0-3.1 mm, or 6.2-7.5 and 3.2-3.4 mm in males and females, respectively. Body nearly entirely pallid (Fig. 5), only dorsal side of head retaining a faint to mediocre, rather uniform brownish coloration often growing a little darker on antennae and pale grey to nearly blackish around ocelli (Fig. 5b).

Male anal shield regularly rounded at caudal margin.

Male leg 18 (Fig. 6b) with a narrow syncoxital notch; telopodite 4-segmented, tarsus with one apical spine.

Telopods (Fig. 6c) with a high, rounded, clearly emarginate, central syncoxital lobe flanked by two setose horns, each latter only slightly higher than central lobe and crowned by a minute, elongate, acute, membranous lobule devoid of adjacent structures. Only prefemur micropapillate laterally. Caudomedial femoral process prominent, directed distomedially at ca 100º to femur, mostly strongly chitinized, only apically with a small membranous sac, but devoid of any chitinized lobe. Caudomedial process of tibia evident, sac-shaped, membranous, with an evident, rounded tubercle on caudal face at base. Tarsus rather modestly curved, subacuminate apically.

Differs from congeners in a partly unpigmented body with only the head retaining some pigment, coupled with a long antennomere 6 which is ca 2.3–2.4 times as long as high, as well as by a rather broad hyposchism produced considerably behind the caudal margin of tergum 2, and only 4-5 transverse striae, of which three cross the dorsum on tergum 2.

To emphasize the provenance from an island. An adjective.

Due to such a troglomorphic feature as a nearly completely unpigmented body, this species may well prove to be a troglobite. This cave on Kalimnos is known to support at least one more endemic troglobite, the woodlouse Cordioniscus kalimnosi Andreev, 1997 (Isopoda, Oniscidea, Styloniscidae) (Schmalfuss 2003).
