Edaphus brachati nov.sp. (figs 38, 59)

Type material: Holotype (): VENEZUELA: Carabobo, Mun. Montalban, Mt. La Copa , 1400- 1500m, 11.I.1007, V. Brachat .- Paratypes: 1, 4: Carabobo, Mun. Bejuma, Cerrode Paja , 1500m, 10 o 16’N, 68 o 14’W, 12.I.2007, V. Brachat GoogleMaps ; 1: Mun. Bejuma, El Maquero , 1200-1300m, 9.-21.I.2007, idem GoogleMaps ; 2: Mun. Bejuma, Palmichal , 950m, 10 o 19’04’’N, 68 o 13’53’’W, 21.I.2007, idem.- HT and PTT in coll. Assing (Hannover), PTT also in the KSEM and in cP GoogleMaps .

D e s c r i p t i o n: Macropterous, reddish brown, shiny, frons finely punctate, rest of surface aside of distinct and dense setiferous punctures impunctate; pubescence recumbent.

L e n g t h: 1.1-1.4mm (forebody: 0.7-0.8mm).

PM of the ht: HW: 35.5; DE: 25; LE: 11; LT: 1; LG:1.5; PW: 36; PL: 33; dlbc: 25; EW: 57; EL: 55; SL: 46.

M a l e: Sternite 8 (fig. 38). Sternite 9 acute apicomedially, no fields of ha present. SpP about as long as the median lobe, with a small double trumpet, vs about one fifth as long as the median lobe. Aedeagus (fig.59), apical portion of median lobe acutely angled, parameres shorter than median lobe, slightly bifid, with 1 very long apical and 1 also very long seta at the small median branch.

Head nearly as broad as the pronotum, eyes large, finely facetted, minute temples indistinct, ptfF distinct, slightly angular, ampF broader than each of the slightly elevated alpF, flat, no distinct separation between ampF and clp, ampF and alpF finely punctate. Antennae slender, when reflexed not extending to the posterior margin of the pronotum, club 2-segmented, segment 10 slightly longer than broad, segment 11 about as long as segment 10. Pronotum slightly broader than long, sides convex anteriorly, shallowly concavely constricted behind; lbc distinct, mbc absent, 6-8 very small bf present. Elytra subtrapezoid, broader than long, sides distinctly, slightly convexely, dilated posteriad, shoulders simple. Mbct3 one third as long as the tergite.

C o m p a r a t i v e n o t e s: This new species resembles strongly E. andersonianus PUTHZ but may be distinguished by the longer antennal segment 10 and the aedeagus.; see also the key.

E t y m o l o g y: This new species is named in honour of the collector Volker Brachat (Geretsried).
