Diagnosis

Differs from the only congener E. sifnium gen. et sp. nov. by the apical margin of the promere being concave, the opisthomere not compressed meso-laterad, e.g., the lateral process (lp on Fig. 4 A-D) parallel to the promere, the lateral process (lp) much broader and the apical posterior process (app) broader and blunter.

Material examined

GREECE: 1 ♂, 2 ♀♀, Antiparos Island, litière [litter], 22 Dec. 1982, leg. P. Beron & St. Andreev, det. Mauriès 1983 (NMNHS); 1 ♂, Sporadhes, Anatoliko Mauri [east Mavri Islet] (Levitha Islands), 18.i.1990 [18 Jan. 1990], S. Sfendourakis leg., ex coll. M. Karamaouna (ZMUC).

Remarks

Male body length 16.9-17.9 mm; height 1-1.2 mm; body ring number: 39-41 podous rings + 2-3 apodous rings + telson; number of ocelli: right side: 30-38, left side: 32-38; developmental stadium IX-X with

8-9 rows of ocelli. Female body length 13.4-18.3 mm; height 1-1.3 mm; body ring number: 37-41 podous rings + 3-5 apodous rings + telson; developmental stadium VIII-IX with 7-8 rows of ocelli.

This species was described on the basis of two males and four females and has only been found once since its description, viz., by Mauriès & Karamaouna (1984) from Antiparos. The new specimens from east Mavri belong to the collection of Karamaouna, but they are slightly different: the apical posterior process (app) of the solenomere is not bifurcated, but undivided and slightly serrated (serration visible in posterior view) (Fig. 4A, C-D).

Distribution

Greece: Cyclades: Naxos Island (type locality), Antiparos Island (Mauriès & Karamaouna 1984); Dodecanese Islands: east Mavri Islet.
