Figure 1 , 25 , 47 .

Holotype. Female. ECUADOR: Orellana: Reserva Ethnica Waorani , 1 km S Onkone Gare Camp, 00 o 39’10S 76 o 26’W 30-VI- 1995, 220 m, Fogging terre firme T.L. Erwin ( USNM). (Specimen point mounted, antenna and gender label affixed to paper point; locality label; second locality label; USNM acronymic label; Holotype label; plastic vial with abdomen and aedeagus.)

Paratypes. Two specimens. Ecuador: Orellana: Reserva Ethnica Waorani , 1 km S of Onkone Gare Camp, 76 o 27’W 00 o 39’S, 9-II- 1995, 216 m, T.L. Erwin ( WOPC, 1) ; Tiputini Biodiversity Station, near Yasuni National Forest , 76 o 08’W 00 o 37’S, 8-II-1999, 220- 250 m, T.L. Erwin ( USNM, 1) .

Diagnosis ( Fig. 47 ). The members of this species most closely resemble those of Amboakis capitata (Gorham) . However, in members of A. ampla , the funicular antennomeres are considerably more expanded (compare Figure 1, 2 ). Moreover, the aedeagus is much longer in A. ampla , than it is in A. capitata (compare Figure 25, 28 ).

Description. Size: Length 6.0 mm: width 2.0 mm. Integument: Cranium reddish-yellow; pronotum black; elytra dark brown, with slight paleness at humerus and at middle; front pair of legs mostly yellow, infuscated, middle and hind pair of legs yellow. Head: Wider than pronotum (38:36); vertex narrower than eye (9:15); funicular antennomeres considerably expanded ( Fig. 1 ). Thorax: Pronotum, transverse (71:51), side margins behind anterior transverse depression more convex than tuberculate, punctations minute, discal trichobothrium set in deep, transverse shallow, and spheroid depression; elytra, form broad rectangular, ratio of elytral length to elytral width 2:5, ratio of elytral length to pronotal length 4:9, punctations small, somewhat aseriate near sutural margin, shallowly impressed, and not wider than width of interstitial spaces, distal margin of epipleuron not spinous, disc vested profusely with dark setae; protibial anterior margin with 6 spines. Abdomen: Aedeagus as in figure 25.

Variation. Size: Length 3.5-6.0 mm: width 1.2-2.0 mm. The small paratype does not show the pale regions of the elytra.

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

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

Etymology. The generic name Amboakis is feminine. The specific epithet ampla is an adjective derived from amplus (= large). I refer to the large size of the terminal antennomere ( Fig. 1 ).

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