Peru: Provincia de Tambopata , Madre de Dios , Rio Tambopata Reserva, 30 km SW Puerto Maldonado, 12°50S' 69°20W' , 2-V- 1984 , 290 m, fogging tree canopy, T. L. Erwin ( USNM ). D i a g n o s i s: The genus Aphelocerus KIRSCH was revised in 2005 (OPITZ 2005). This work included a key to species. Aphelocerus ligulus specimens key out to A. batesi OPITZ from which A. ligulus specimens differ by showing shorter phallobasic lobes that are shorter, wider, and more acuminate. D e s c r i p t i o n: Size: Length 4.0 mm; width 2.0 mm. Form: As in Fig. 263 . Color: Black; row of white setae at base of elytral sutural margin contiguous with anterior patch of white setae, elytral disc posterior patch of white setae minimally developed. Head: Interocular depression and frontal umbo shallow; antenna ( Fig. 8 ) capitate, funicular antennomeres filiform, progressively shorter and wider towards capitulum, capitulum compact; eyes finely facetted, eye narrower than frons (EW/FW 16/34). Thorax: Pronotum ( Fig. 101 ) quadrate, very finely punctate; (PW/PL 65/65); elytral disc with two patches of white setae, anterior patch obliquely positioned and oblong, posterior patch very small, disc impressed with small setiferous punctures (EL/EW 200/60). Abdomen: Pygidium transverse / scutiform; aedeagus as in Fig. 202. N a t u r a l H i s t o r y: The available specimen was collected during May, at 290 m , by fogging tree canopy. D i s t r i b u t i o n: ThisspeciesisknownfromPeru. E t y m o l o g y: The trivial name, ligulus , is a Latin noun with the meaning of "ladle"; with reference to spoon-shaped aedeagus.
