Edaphus ecuadorensis   nov.sp. (figs 11, 33, 48)

Type material: Holotype (): ECUADOR: Napo, Yuturi Lodge, Rio Napo, 0 o 32‘57‘‘S, 76 o 2‘18‘‘W, FIT, 20.-21.III.1989, R. Brooks & D. Brzoska: in the KSEM. GoogleMaps  

D e s c r i p t i o n: Macropterous brownish, basal half of elytra less dark than apical half, shiny, pronotum with about 17 puncture-like impressions, as elytra very finely punctate, pubescence short, semirerect on pronotum, recumbent elsewhere.

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

PM of the ht: HW: 47; DE: 30; LE: 14; LT:-; LG: -; PW: 50; PL:37; dlbc: 40; EW: 67; EL: 57; SL: 45.

M a l e: Sternite 8 (fig. 33). Sternite 9 acute apicomedially, no fields of ha present. SpP about as long as the median lobe, tubular, vs smaller than apical portion of the median lobe. Aedeagus (fig. 48), apical portion of median lobe lanceolate, with two setae, parameres much shorter than median lobe, with one short apical and one also short subapical seta.

Head slightly narrower than elytra, eyes very large, no distinct temples present, ptfF distinct, alfF very short, ampF much broader than each of the callus-like elevated alpF, flat, no special separation between ampF and clp. Antennae robust, when reflexed about the last segment extends beyond the posterior margin of the pronotum, club 2-segmented, segment 10 slightly longer than segments 5-9 combined, nearly twice as long as broad, segment 11 about as long as segment 10. Pronotum much broader than long, sides moderately convex anteriorly, lateral margination curved up in anterior fifth, sides moderately concavely constricted behind; base with short lbc, a distinct mbc extending to base proper and 6 bf about equal in size; about 17 small puncture-like impressions on disc (fig.11); punctuation very fine, rather dense, interstices larger than punctures. Elytra large, distinctly broader than long, sides very shallowly convexely dilated, shoulders simple; punctuation fine, moderately dense, punctures different in size, interstices up to twice as wide as diameter of punctures. Mbct3 two thirds 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 E. poulaini OROUSSET   , from which it may be at once distinguished by the greater size, see also the key.

E t y m o l o g y: The name refers to the country in which the new species was found.
