Ambonoides caraguata OPITZ nov. sp.

( Figs 63 , 111, 112 , 146 , 175 )

Holotype: ♀. Rio Caraguatá , M. Grosso, Brasil, XII:8: 1953, 21°48'; 52°27', 400 m, F. Plaumann ( FMNH) .

Paratypes: Two specimens. Brazil, Rio Caraguatá: 17-VIII-1953, 21°48' 52°27', Fritz Plaumann ( FMNH, 1) ; idem, 31-VIII-1953, 21°48' 52°27', F. Plaumann ( WOPC, 1) .

Diagnosis: The members of this species resemble superficially those of Ambonoides retinoides . However, in A. caraguata specimens the legs are bicolored, whereas in specimens of retinoides the legs are entirely black.

Description: Size: Length 7.0 mm; width 2.0 mm. Form: As in Fig. 146 . Color: Cranium mostly black, lower frons and clypeus flavotestaceous; pronotum mostly black, upper sides, anterior margin, and small anterior wedged-shaped macula flavotestaceous; elytral disc mostly black, with midelytral flavotestaceous fascia, humeral angle faintly testaceous. Head: Antennal capitulum very long ( Fig. 63 ), each capitular antennomeres nearly as long as combined length funicular antennomeres; antennal carina very prominent; EW/FW 10/15. Thorax: Pronotal anterior margin not projected at middle, sides of disc depressed; side margin of disc rounded; PW/PL 38/38; elytra rectangular, sides sharply deflexed; EL/EW 165/33. Abdomen: Male pygidium not incised at distal margin; aedeagus as in Figs. 111, 112 , tegminal lobes acuminate, phallic apex particularly elongate.

Natural history: Specimens were collected during August.

Variation: Size: length 6.0-7.0 mm; width 1.5-2.0 mm. The elytra may be entirely black, or flavotestaceous in elytral basal half and black in remainder.

Distribution ( Fig. 175 ): This species is known only from the type locality.

Etymology: The trivial name, caraguata, constitutes a noun in apposition and refers to the type locality.
