Paratypes. Two specimens. Ecuador: Orellana: Reserva Ethnica, Waorani , 1 km S Onkone Gare Camp, 00 o 39’10S 76 o 26’W, 9-II- 1995, 220 m, Fogging terre firme T.L. Erwin ( USNM, 1) ; Tiputini Biodiversity Station, near Yasuni National Forest , 00 o 37’S 76 o 08’W, 7-II-1999, 220- 250 m, Fogging terre firme T.L. Erwin ( WOPC, 1)

Diagnosis ( Fig. 48 ): The members of this species resemble superficially those of Amboakis nova (Opitz) and A. barinas Opitz. From A. nova specimens, A. antegalba , new species, specimens differ by having the pronotal arch yellow at the middle, and from Amboakis nova specimens by having minute pronotal punctations.

Description. Size: Length 5.0 mm: width 1.5 mm. Integument: Cranium bicolorous, mostly yellow, frons infuscated; pronotum mostly black, arch yellow at middle; elytra dark brown, slightly pale at middle; front pair of legs mostly yellow, infuscated, middle and hind pair of legs yellow. Head: Wider than pronotum (31:29); vertex narrower than eye (6:12); funicular antennomeres considerably expanded ( Fig. 9 ). Thorax: Pronotum, transverse (57:52), side margins behind anterior transverse depression more convex than tuberculate, punctations minute, discal trichobothrium set in deep, transverse shallow, and spheroid depression; elytra, form narrow rectangular, ratio of elytral length to elytral width 2:5, ratio of elytral length to pronotal length 4:4, punctations small, punctations somewhat aseriate near sutural margin, punctations shallowly impressed, not wider than width of interstitial spaces, distal margin of epipleuron not spinous, disc vested profusely with dark setae; protibial anterior margin with 10 spines. Abdomen: Aedeagus as in figure 26.

Variation. Size: Length 4.8-5.0 mm: width 1.2-1.5 mm. Other than size, the available specimens are quite homogeneous.

Natural History. Specimens were collected during February, at 216- 250 m.

Distribution. From the Reserva Ethnica Waorani and the environs of the Yasuni National Forest of eastern Ecuador.

Etymology. The specific epithet antegalba is a Latin compound name derived from ante (= before) and galbus (= yellow). I refer to the yellow marking on the pronotal arch.

Taxonomic Notes. Among the Amboakis species keyed in Opitz (2006: 119) A. antegalba , is most closely related to the Brazilian A. capitata Opitz. The following changes are made to the aforementioned key:

10(9'). Funicular antennomeres very expanded ................................................................................... 11 – Funicular antennomeres slightly expanded (Fig. 91, in Opitz 2006) ( Brazil: Amazonas) .............

...................................................................................................... Amboakis funebris Opitz

11(10). Pronotum uniformly black ( Venezuela: Barinas) .............................. Amboakis barinas Opitz – Pronotum not uniformly lack, pronotal arch yellow at middle ( Ecuador: Orellana) .....................
