Pelonium falcatum OPITZ nov.sp. ( Figs 17 View Figs 1-27 , 178, 243, 333)

Holotype: ♂. Type locality: FRENCH GUIANA: Amazon Nature Lodge , 30 km SE Roura on Kaw Rd., 2-9-VI-2005, J. E. Eger & M. T. Messenger, coll. A second label reads: N04°33.570' W052°12.433', 300 m, UV Trap ( FSCA).

D i a g n o s i s: The available specimen superficially resembles members of Pelonium niveum (CHEVROLAT), from which the holotype of this species differs by showing a sickle-shaped 8 th antennomere ( Fig. 17 View Figs 1-27 ). The genus Pelonium SPINOLA was revised by OPITZ (2018b).

D e s c r i p t i o n: Size: Length 5.2 mm; width 2.0 mm. Form: As in Fig. 333 View Figs 330-333 . Color: Cranium castaneous; antenna brown; prothorax bicolorous, venter and pronotal disc black; pronotal sides testaceous; mesosternum and metasternum black; mesepisternum and metepisternum testaceous; legs and abdomen testaceous. Head: Cranium coarsely punctate; antenna ( Fig. 17 View Figs 1-27 ) capitate, funicular antennomeres shorter towards capitulum, 8 th antennomere sickle-shaped, capitular antennomeres 9 and 10 with collateral branch, antennomere 11 oblong; eyes large, coarsely facetted, eye wider than frons (EW/FW 37/8). Thorax: Pronotum ( Fig. 178 View Figs 171-178 ) oblong (PW/PL 68/82), disc subglabrous, lateral tubercles well developed, disc densely covered with white setae; elytra sculptured with small asetiferous punctures that diminish near elytral middle, disc profusely covered with short white setae (EL/EW 230/60). Abdomen: Pygidium scutiform; aedeagus as in Fig. 243. View Figs 243-248

D i s t r i b u t i o n: This species is known from French Guiana. E t y m o l o g y: The trivial name, falcatum, is a Latin name that stems from falcatus (= sickle-shaped); with reference to the shape of the 8 th antennomere.
