Brooks, ( PERU1B00 100), flight intercept trap( KU).   Diagnosis: At present, only 2 species of the genus are known from the Neotropics. Therefore, the diagnosis given in  P. crassulusinforms about the differences between the two species.   Description:  Length: 2.0 mm. Colour: yellow, antennae and legs lighter yellow.  Head: 0.25 mmwide, 0.35 mmlong; 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. Antennaewith 2 ndand 3 rdantennomere equal in length; 4 thto 6 thantennomeres not wider than preceding antennomeres; 4 thand 5 thantennomeres quadrate, 6 thone shorter, wider than long; antennomeres 7 to 11 distinctly wider than preceding antennomeres; 7 thantennomere quadrate, 8 thdistinctly shorter and smaller; the penultimate antennomeres wider than long.  Pronotum: 0.28 mmlong, 0.38 mmwide; 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 mmlong, 0.45 mmwide; with similar punctation as on pronotum; surface polished.  Abdomenwith 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. 3118920349 [189,627,690,712] Brazil Bresil 4 335 1 1 holotype 3118920391 IRSNB Guadeloupe Base 4 335 1 1 syntype 3118920358 [251,956,799,821] Alto 4 335 1 Madre de Dios 3118920329 2000-10-23 2000-10-26 2000-10-23 KU R.
