Megaphloeus yasuni OPITZ nov.sp. ( Figs 84 , 189 , 301 )

Holotype: ♀. Type locality: ECUADOR, Napo, Yasuni Res. Sta. 19-30 Oct 1998, W. J. Hanson 250 m ( FSCA).

D i a g n o s i s: In this beetle, the elytral disc shows a testaceous crescentic marking extended from the elytral basal margin. Also, the elytral disc shows a rectangulate testaceous fascia at the middle. These two characteristics will distinguish the members of this species from congeners. The genus Megaphloeus OPITZ was revised in 2011 ( OPITZ 2011a).

D e s c r i p t i o n: Size: Length 5.0 mm; width 1.5 mm. Form: As in Fig. 301 . Color: Cranium mostly castaneous, frons with black spot, epicranium black; antenna mostly black, scape yellow; prothorax mostly black; pronotal arch testaceous; mesepisternum black, rest of pterothorax testaceous; elytron mostly black, with testaceous crescentic marking extended from elytral basal margin, and with rectangular testaceous fascia at middle. Head: Antenna ( Fig. 84 ) capitate, funicular antennomeres shorter towards capitulum, capitular antennomeres 9 and 10 triangular, antennomere 11 ovoid; eyes large, finely facetted, eye slightly wider than frons (EW/FW 25/20). Thorax: Pronotum ( Fig. 189 ) quadrate (PW/PL 60/45), disc finely punctate, lateral tubercle well developed; elytra sculptured with profusely distributed small asetiferous punctures (EL/EW 220/50). Abdomen: Pygidium scutiform.

N a t u r a l H i s t o r y: The holotype was collected during October at 250 m.

D i s t r i b u t i o n: This species is known from Ecuador.

E t y m o l o g y: The trivial name, yasuni, is a noun in apposition and refers to the type locality.
