Fig. 24

Eotrechus pilicaudatus Tran & Zettel, 2006: 40-43, figs 1-8 (type locality: Meghalaya, NE India).

Material examined.

Holotype: India • ♂ (apterous); Meghalaya, 3 km E Tura; 25°30'N, 94°14'E; 1150 m a.s.l.; 18 Apr. 1999; L. Dembický & P. Pacholátko leg.; NHMW.

Diagnosis.

Size: apterous male: length (excluding genitalia) 6.50; width 2.40. Mesosternum ca. 4.0 × length of metasternum. Male: fore femur incrassate at basal part and tapering towards apex; middle and hind trochanters and basal part of middle and hind femur with many small spines; sternum VII about twice as long as two preceding sterna combined, posterior margin slightly emarginated. Male genitalia: abdominal segment VIII large; pygophore suboval, without lateral projections but with large tufts of long, black posterolateral setae, posterior margin with paired, small, pointed, black processes consisting of tightly packed, thick setae; proctiger with paired long, bristle-like, black setal tufts distolaterally. Female unknown.

Remarks.

This species is unique in having thick pilosity on the genitalia. Based on the absence of a caudal projection on the pygophore, this species can be placed in the E. hygropetricus species group. A comparison between E. pilicaudatus and E. hygropetricus was discussed in detail by Tran and Zettel (2006: 41, 43).

Distribution.

India: Meghalaya (Tran and Zettel 2006) (Fig. 24).

Eotrechus longipes species group

Diagnosis. Male: fore femur moderately incrassate, tapering towards apex; posterior margin of sternum VII emarginated medially; genitalia large: pygophore with a pair of posterolateral projections; proctiger slender, with subtriangular apex. Female: sternum VII 1.1-1.5 × length of two preceding sterna combined, posterior margin medially produced (except in E. anderseni sp. nov.); genitalia visible in lateral view (only partly visible in E. anderseni sp. nov.).

Species included. E. longipes Andersen, 1982, E. terrestris Andersen, 1982, and E. anderseni sp. nov.
