Edaphus variipunctus nov.sp. (figs 7, 52, 60)

Type material: Holotype (): PERU: Dept. Loreto, Campamento San Jacinto , 2 o 18’75’’N, 75 o 51’77’’W, 175-215m, 3.VII.1993, R. Leschen # 13: in the KSEM.

D e s c r i p t i o n: Macropterous, moderately shiny, pronotum with 16 small puncturelike impressions on disc (fig. 7), elytra with dense setiferous punctures and some interspersed large punctures; pubescence short, recumbent.

L e n g t h: 1.0mm (forebody: 0.6mm).

PM of the ht: HW: 28; DE: 17.5; LE: 9; LT: -; LG: 2; PW: 31; PL: 26; dlbc: 25; EW: 45; EL: 40.5; SL: 31.

M a l e: Sternite 8 with a small notch in about posterior third. Sternite 9 acute apicomedially, no fields of ha present. SpP about 2x as long as the median lobe, tubular with a curved distal tube, vs small (fig. 52). Aedeagus (fig. 60), apical portion of median lobe acutely angled narrowed, parameres shorter than median lobe, with one short apical and one short subapical seta.

Head slightly narrower than pronotum, eyes very large, no distinct temples present, ptfF distinct, alfF short, ampF broader than each of the moderately elevated alpF. Antennae short, when reflexed not extending to the posterior margin of the pronotum, club 2-segmented, segment 10 about as broad as long, segment 11 slightly longer than segment 10. Pronotum broader than long, sides moderately convex anteriorly with a minute tooth apicolaterally, sides moderately constricted behind; base with short lbc and 6 moderately large bf, no mbc present; pronotal disc with about 8 puncture-like impressions on each lateral half, impressions smaller than bf. Elytra subquadrate, broader than long, sides moderately convex; shoulders with a short intrahumeral stria extending cariniform mediad toward a small puncture; setiferous punctures very dense, numerous fine punctures interspersed on the median area of each elytron (fig. 7). 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 is remarkable by the elytral punctuation and the peculiar SpP. It may be distinguished from its relatives as indicated in the key.

E t y m o l o g y: Since the elytra have punctures of different size I name this new species " variipunctus " (Lat.= with different punctures).
