Holotype.
VENEZUELA, Amazonas, Cerro de la Neblina (Smithsonian Basecamp), 140 m, 0.0148°N, 66.1604°W, 10-20 February 1985 (PJ Spangler, PM Spangler, RE Faitoute & WE Steiner)(NMNH: ADP124944, female).
Derivation of specific epithet.
The epithet “neblinensis” is a Latinized noun in apposition, based on a geographic name formed from Pico de Neblina, a tipui on the border of Venezuela and Brazil, the area in which adults of this species have been found, and the Latin suffix „-ensis,“ meaning of, or from that place.
Proposed English vernacular name.
Tipui trough beetle.
Diagnosis.
With the attributes of the genus as described above and medium sized for the genus as it is presently understood; adults have castaneous integument, except anterior parts of mandible, baso-lateral corner of labrum, and clypeal suture piceous. Frons with nearly effaced rugae, punctulate. Occiput punctulate. Pronotum nearly quadrate with lateral margins straight to hind angle, hind angle a very small tooth; base densely rugulose. Elytra broad and short, slightly wider than the width of pronotum across anterior third, and with 6 evident shallowly impressed interneurs, 7-8 nearly effaced; margins behind humeri moderately serrulate. Foreleg femur with markedly developed and produced ridge on postero-ventral margin.
Description.
( Figs 15 View Plate 4 , 35 View Plate 10 ). Size: See Appendix 1. Medium sized for the genus, ABL = 6.4-6.9 mm, SBL = 5.54-6.12 mm, TW = 2.25-2.46 mm. Color: see diagnosis, above. Luster: Head, pronotum, elytra and legs shiny, microsculpture absent. Head: Labrum quadrate and apico- medially emarginate. Eye large, moderately convex. Gena moderately long, straight. Frons, occiput, and gena glabrous. Prothorax: Broad, narrowed slightly toward base, margin narrowly explanate except wider at hind angle, hind angle a very small tooth; surface punctulate, punctures widespread, glabrous. Pterothorax: Elytron moderately convex, disk flat, intervals flat, interneurs striato-punctate, punctures small, shallow, apex oblique and straight, sutural apex narrowly rounded. Metasternum sparsely setiferous in male. Legs: Normal in both sexes; foreleg femur (as in Fig. 22 View Plate 6 ) ridged along the posterio-ventral margin and markedly produced at middle of ridge; posterior trochanter narrowly rounded at apex, about half the length of the femur. Abdomen: Abdominal sterna moderately setiferous; sternum IV of female with denser patch of setae at midline. Male genitalia: Median lobe ( Fig. 35 View Plate 10 ) short and robust with ostium moderately elongate, over half the length of the median lobe; apex a short blunt distal end, slightly curved in lateral aspect, ventral margin proximal to apex evenly arched and barely curved to apex; endophallus with complexly folded tracheal fields; phallobase hooded, opening more or less five degrees off axis of shaft. Parameres large, left a third longer than the right, both broadly rounded, asetose. Female genitalia: Not investigated; however, it is likely similar to that illustrated on Plate 11 View Plate 11 .
Dispersal potential.
These beetles are macropterous and capable of flight. They are moderately swift and agile runners.
Way of life.
The adult holotype was collected in a flight intercept trap in the rainforest understory. Adults are active in February, in the rainy season.
