Edaphus foveolicollis nov. sp. (figs 12, 23, 50)

Type material: Holotype (): PERU: Dept. Loreto, 1.5 km N Teniente Lopez , 2 o 35’66’’S, 76 o 06’92’’W, FIT, 210-240m, 26.VII.1993, R. Leschen #211; 1 - paratype: ibidem, 24.VII.1993, idem # 189: iin the KSEM.

D e s c r i p t i o n: Macropterous, brown, shiny, pronotum very finely punctate and with numerous puncture-like impressions on disc (fig. 12), elytra impunctate, pubescence short, semierect on pronotum elsewhere recumbent.

L e n g t h: 1.4-1.5mm (forebody 0.8-0.9mm).

PM of the ht: HW: 43.5; DE: 25; LE: 13; LT: -; LG: 2; PW: 49; PL: 40; dlbc: 39.5; EW: 72; EL: 61; SL: 49.

M a l e: Sternite 8 (fig. 23). Sternite 9 acute apicomedially, no fields of ha. SpP tubular, nearly twice as long as the median lobe, vs? Aedeagus (fig. 50), anterior portion of median lobe acutely angled, two long setae medially, parameres shorter than median lobe, narrow, with one short apical and one short preapical seta.

Head slightly narrower than pronotum, eyes very large, no distinct temples present, ptfF inclusively alfF distinct, ampF broader than each of the alpF, flat, alpF moderately elevated, no special separation between ampF and clp. Antennae robust, when reflexed slightly extending beyond the posterior margin of the pronotum, club 2-segmented, segment 10 as long as segments 6-9 combined, distinctly somewhat longer than broad, segment 11 slightly longer than segment 10. Pronotum much broader than long, sides moderately convex anteriorly, lateral margination slightly curved up anteriorly, sides distinctly constricted posteriorly; base with short lbc and 6 moderately large bf, no mbc present; pronotal disc with about 30 puncture-like impressions, punctuation (setiferous punctures) very fine, dense. Elytra very large, broader than long, sides moderately convexely dilated, shoulders with a short intrahumeral stria extending cariniform mediad toward a small puncture-like impression. Mbct3 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 by habitus generally E. ecuadorensis sp. n., but may be easily distinguished by the missing mbc, more and smaller pronotal impressions and by the humeral characters; see also the key.

E t y m o l o g y: Because of the small puncture-like impressions on the disc of the pronotum I name this new species " foveolicollis " (Lat.= with small puncture-like impressions on pronotum).
