T y p e m a t e r i a l: Holotype (): VIETNAM: Hatinh Prov. , Raô An, 13 km W Huang Son, rt. 8 7 km S Nuòc Sôt village, 18 o 21’N, 105 o 15’E, 300m, flight interception trap, 9.-22.V.1998, Lee Herman GoogleMaps ; Paratypes: 1: ibidem, 220m, litter as base of boulders in forest, 6.V.1998, L. Herman; 1 Hatinh Prov. , Ke Co Reservoir, 18 o 09’N, 105 o 55’E, 12.IV.1998, L. Herman: HT and 1 pt in the AMNH, 1 pt in cP GoogleMaps .

D e s c r i p t i o n: Large, macropterous, chestnut brown, shiny, impunctate, pubescence dense, semierect.

Length: 2.0- 2.6mm (fore body: 1.1-1.3mm).

PM of the ht: HW: 49; DE: 38; LE: 12: LT: -; LG: 3; PW: 59; PL: 54; dlbc: 43; EW: 83; EL: 75: SL: 61.

M a l e: Unknown.

Head distinctly narrower than elytra, eyes large, finely facetted, no distinct temples, ptfF and (short) alfF distinct, ampF nearly twice as broad as each of the alpF, flat, not distinctly separated from clp, alpF nodiform, each with one minute punctures, few minute punctures near alfF anteromedially. Antennae long, when reflexed extending to the posterior margin of the pronotum, club 2-segmented, segment 10 distinctly, but not much, longer than broad. Pronotum broader than long, sides convex anteriorly, strongly constricted behind, lbc distinct, mbc extending to base proper, 6 large bf present; along the middle of the pronotum there can be seen a strong, narrow incision/furrow, which is separated from the anterior margin of the pronotum by the length of antennal segment 3. Elytra very large, broader than long, sides moderately convex, shoulders simple. Tergite 3 and 4 with long mbc, mbct5 longer than half of the tergite.

C o m p a r a t i v e n o t e s: In my key (1979b) this remarkable new species should be inserted at column 83; from E furcaticollis PUTHZ it may be easily distinguished by the median carinae of tergites 3-5 and the size.

E t y m o l o g y: Because of the narrow longitudinal furrows of the pronotum I name this species " incisionicollis " (Lat.= with an incision on pronotum).
