03A0AB75E648FF9BFE988DD6FDCBAA78.taxon	description	DESCRIPTION. Length of adults 8 – 9 (♂) or 9 – 11 mm (♀), width 0.8 – 0.9 (♂) or 1.0 – 1.1 mm (♀). Holotype ca 8 mm long and 0.8 mm wide. Coloration of adults and subadults yellowish to brown, often apparently faded due to long preservation in ethanol (Fig. 1), sometimes with marbled, brown to blackish spots dorsally and on sides of prozonae, divided by a pale axial line and paler patches laterally and ventrolaterally. Metazonae almost entirely pale yellowish to brown, only sometimes with somewhat darker, marbled knobs supporting macrochaetae. Antennae brown to dark brown throughout, except for a pallid tip. Head especially dark on vertex, distinctly marbled. Venter yellowish. Legs pale to brown, increasingly darker toward distal podomeres. Body with 28 segments, including telson (26 p + 1 a + T), subcylindrical, without evident lateral swellings, let alone keels, on metazonae (Fig. 1), somewhat more slender in ♂ compared to ♀. Antennae long and slender, in situ reaching past segment 4 or 5 when stretched laterally, antennomere 3 being the longest. Frons flattened (♂) or regularly convex (♀). Eyes black, 16 – 18 ocelli in a roundly triangular field from each side of head. In width, collum <head = segment 2 = 3 <4 – 22 (23), gently and regularly tapering thereafter. Only two or three postcollum segments with poorly-developed, rounded, lateral swellings instead of paraterga. Metatergal macrochaetae borne on minute knobs, arranged in an almost transverse row, either medium-sized, pointed and thin on two or three anteriormost segments or increasingly thick, short, blunt and subbacilliform thereafter towards telson; lateral macrochaetae longest, reaching in length ca 1 / 4 metatergal width (Figs 1, 8). Legs long and slender, a little shorter in ♀, with accessory claws, but only ♂ tarsi 3 – 6 (7) sometimes with ventral papillae (Fig. 9), mostly apapillate (Figs 3, 4). Pairs 1 and 2 distinctly reduced in size as usual, ♂ pairs 3 – 7 almost normal, only slightly enlarged due to coxites; ♂ leg 7 (Figs 3, 9) with a peculiar distoventral swelling on coxa and a smaller caudoparabasal cone on prefemur; ♂ pairs 10 and 11 each with coxal glands (Fig. 4), like a number of following pairs each with a ventral row of strong and spiniform setae on both femur and, especially, prefemur (Fig. 4); each ♀ coxa 2 with a strong, ventral, distally rounded, digitiform process forming a medially subcontiguous pair. Anterior gonopods (Figs 5, 6, 10 – 14) placed on an evident plate-like sternum (st) with lateral tracheal apodemes, high, held parallel to each other, fully independent, curved caudally, clearly tripartite: each composed of a lateral, relatively short, blunt to subacuminate, hyaline lamella (hl), vs slender and finger-shaped in E. reductum sp. n., semi-circular with a basal constriction in E. chichkan sp. n., and linguiform and blunt in E. speophilum; more mesally a longer, conspicuously divided solenomere (sl) carrying a small, midway, caudal lobule (j) and a barbed / fringed distal quarter; and a very long pseudoflagellum (pfl), slightly serrate or undulate at caudal margin. Posterior gonopods (Fig. 7, 10, 15 – 17) particularly simple, mostly composed of medially contiguous, elongated coxites, both somewhat excavate on caudal face, usually produced apically into a small and setose appendage (telopodite remnant) of varying shapes (Figs 15 – 17), often showing traces of a dark pigment inside, and only occasionally with discernible coxal pouches or sacs (cs) with small projections medially. Vulva with a characteristic beak-shaped caudolateral structure behind operculum (Fig. 18).	en	Golovatch, S. I., Spelda, J.

03A0AB75E64CFF98FCA28FB9FE74A95F.taxon	diagnosis	DIAGNOSIS. Differs from congeners by a pallid coloration with only five light brown ocelli on each side of the head. ♂ legs 7 are with a pair of strong hooks on the coxae and small glandular parabasal knobs on the prefemora (Fig. 26). Coxal pouches (cs) of the posterior gonopods are membranous (see also key below). BRIEF REDESCRIPTON. Length ca 14 mm, width 1.1 mm on mandibular genae, 1.0 mm on midbody segments (♂). All characters as in E. reductum sp. n., except as follows. Coloration pallid, only 5 ocelli on each side of head light brown. Body with 28 segments. Antennae longer, reaching segment 6 when stretched laterally, antennomere 3 being the longest. Metatergal macrochaetae mostly bacilliform and blunt (Fig. 24). ♂ leg-pairs 3 – 6 only slightly enlarged, with tarsal papillae distally; each ♂ leg 7 (Fig. 26) with a laterally micropapillate coxa carrying a strong ventral hook directed distad, while prefemur with a small, glandular, parabasal knob ventrally; ♂ legs 10 and 11 with coxal sacs / glands (Figs 27, 28), usual, devoid of tarsal papillae like following legs. Anterior gonopods (Figs 29, 30) much like in E. reductum sp. n., but differing in the absence of a lobule (j) on each solenomere (sl), thus being very similar to those of E. chichkan sp. n .. Posterior gonopods (Fig. 31) also very similar to those in E. chichkan sp. n., both coxites being quite high, sac-shaped and densely setose, while coxal pouches or sacs (cs) with membranous projections.	en	Golovatch, S.
