Type material examined:

Brazil: Brésil , without further data, 1 female   , Guadeloupe: Base terre, without further data, 1 female (syntypes, IRSNB)   .

Additional material examined:

Peru: Madre de Dios, Pentiacolla Lodge, 5.5 km NW El Mirador Trail, Alto   Madre de Dios River (12°30.10'S, 71°15.28'W), 500 m elevation, 23.-26.Oct.2000, 1 female, leg. R. Brooks, ( PERU 1B00 100), flight intercept trap ( KU) GoogleMaps   .

Diagnosis:

At present, only 2 species of the genus are known from the Neotropics. Therefore, the diagnosis given in P. crassulus   informs about the differences between the two species.

Description:

Length: 2.0 mm. Colour: yellow, antennae and legs lighter yellow.

Head: 0.25 mm wide, 0.35 mm long; eyes large, 3 times longer than temples; temples with distinct angles; punctation distinct, but sparse and moderately fine; distance between punctures on average wider than diameter of punctures; surface shiny with weak and sparse microsculpture. Antennae with 2 nd and 3 rd antennomere equal in length; 4 th to 6 th antennomeres not wider than preceding antennomeres; 4 th and 5 th antennomeres quadrate, 6 th one shorter, wider than long; antennomeres 7 to 11 distinctly wider than preceding antennomeres; 7 th antennomere quadrate, 8 th distinctly shorter and smaller; the penultimate antennomeres wider than long.

Pronotum: 0.28 mm long, 0.38 mm wide; distinctly emarginate in front of posterior edge; 0.3 times as wide as at anterior angles; punctation slightly coarser and denser than on head, in particular on both sides of the midline; distance between punctures on average smaller than diameter of punctures; surface shiny and nearly polished; with weak irregular microsculpture.

Elytra: 0.43 mm long, 0.45 mm wide; with similar punctation as on pronotum; surface polished.

Abdomen with finer and sparser punctation than on elytra and microsculpture more distinct than on fore body; scarcely shiny; laterally with long dark setae, tergite of last abdominal segment with distinct central tooth.
