Amboakis expandosa OPITZ nov.sp. ( Figs 54 , 187 , 286 )

Holotype: ♀. Type locality: PERU, Madre de Dios, Rio Tambopata Res. , 30 km (air) sw Pto. Maldonado, 290 m, 12°50'S 069°20'W. A second label reads: Smithsonian Institution Canopy Fogging Project, T. L. Erwin et al. colls, 14 Sep 84, 01/02/086. A third label reads: FOGGING 0021270 ( USNM).

D i a g n o s i s: The genus name Amboakis OPITZ, and its 24 species, were made available in 2006 (OPITZ 2006). This work included a key to Amboakis species. Amboakis expandosa specimens key out to A. barinas OPITZ, from which A. expandosa specimens differ by showing a more transverse pronotum.

D e s c r i p t i o n: Size: Length 5.0 mm; width 1.6 mm. Form: As in Fig. 286 . Color: Cranium bicolorous, frons and epicranium black, remainder testaceous; antenna black; prothorax bicolored, anterior 1/2 of pronotum testaceous, piceous in posterior 1/2, prothoracic sternum testaceous; pterothorax piceous; elytra mostly brown, epipleural fold partially yellow; legs bicolorous, femora mostly yellow, posterior margin brown, tibiae brown. Head: Antenna ( Fig. 54 ) capitate, funicular antennomeres expanded laterally, capitular antennomeres oblong; eyes large, finely facetted, ocular notch large, eye much wider than frons (EW/FW 30/20). Thorax: Pronotum ( Fig. 187 ) transverse (PW/PL 77/57), anterior transverse depression deeply impressed; disc finely punctate, lateral tubercle well developed, disc concave paralaterally near pronotal collar; discal and lateral trichobothria prominent; elytral asetiferous punctures profusely distributed, punctures substriate in elytral basal 1/2 (EL/EW 240/60); anterior margin of protibia with 5 spines. Abdomen: Pygidium scutiform.

N a t u r a l H i s t o r y: The available specimen was collected during September, at 290 m.

D i s t r i b u t i o n: ThisspeciesisknownfromPeru.

E t y m o l o g y: The trivial name, expandosa, is a Latin name that stems from expando (= spread out); with reference to the transverse condition of the funicular antennomeres.
