Edaphus lineationifer nov.sp.

T y p e m a t e r i a l Holotype (): NEPAL: Annapurna Mountains , Telbrung Danda near Gangpokhara, 2700m, 12./ 13.VI.1997, O. Jäger: in the MTD.

D e s c r i p t i o n: Micropterous, reddish brown, shiny, frons distinctly, pronotum very finely punctate, pubescence recumbent.

Length: 1.6mm (fore body: 0.9mm).

PM of the HT: HW: 40; DE: 32; LE: 9; LT: -; LG: 3; PW: 48; PL: 41; dlbc: 32; EW: 63; EL: 47; SL: 38.

M a l e: Unknown.

Head distinctly narrower than pronotum, eyes moderately coarsely facetted, moderate in size, no distinct temples, ptfF missing, alfF distinct, short, ampF as broad as each of the alpF, convex, no distinct separation between ampF and clp, the whole frons distinctly punctate, punctures slightly smaller than eye facets, interstices wider than punctures. Antennae moderately long, when reflexed nearly extending to the posterior margin of the pronotum, club 2-segmented, segment 10 distinctly broader than long. Pronotum broader than long, sides slightly convex anteriorly, strongly constricted behind, lbc distinct, mbc extending to base proper, 6 bf present; mbc very narrowly elongated anteriad, separate from anterior margin of pronotum by about one eye length; beside the elongates mbc there can be seen extremely narrow longitudinal furrows; furthermore there are two short transverse, narrow furrows in about the middle of pronotum between mbc and anterior ends of lbc; punctuation on disc very fine, sparse, interstices about twice as wide as punctures. Elytra trapeziform, much broader than long, shoulders simple, minute setiferous punctures sparse, interstices more than 3x as wide as minute punctures. Mbct3 short, less long than half the tergite.

C o m p a r a t i v e n o t e s: This new species is the sister species of E. lineolatus PUTHZ , from which it may be distinguished by distinct (coarser) punctuation of frons, finely punctate pronotum, sparser elytral punctuation (in E. lineolatus interstices between minute setiferious punctures are about twice as wide as punctures) and by the shorter mbct3 (in E. lineolatus mbct3 extends to the posterior margin of the tergite). Because of the short elytra this new species should be inserted in my key (1979b) at column 38; from E. fossicollis PUTHZ it is at once distinguished by the 6 much smaller bf and the punctate frons.

E t y m o l o g y: Because of the thread like longitudinal furrows of the pronotum I name this species " lineationifer " (Lat.= with lines on the pronotum).
