The Neotropical species of the genus Osoriellus FAGEL, 1959 (Coleoptera: Staphylinidae: Osoriinae) Irmler, Ulrich Beiträge Zur Entomologie = Contributions to Entomology 2014 2014-12-15 64 2 231 354 6TBP4 Irmler, 2014 Irmler 2014 [189,405,915,942] Insecta Staphylinidae Osoriellus GBIF Animalia Coleoptera 15 246 Arthropoda species pubescens sp. nov.  ( Figs 23A-C, 27D)   Type material:  Holotype, male:  Panama: Veraguas,  6.1 kmN of Santa Fe, Cerro Tute( 81°07.06'W, 8°30.30'N),  1220 melevation, cloud forest litter,  13.6.1996, leg. R. Anderson, #PAN2A96 96-127D ( KNHM).   Paratypes:  Panama: Chiriqui, La Fortuna, Continental Divide Trail( 82°12.0'W, 8°46.0'N),  1200 melevation, berlese forest litter, abdomen lost,  9.6.1995, leg. R. Anderson, #PAN 2A95 10B ( UIC);   Costa Rica: Alajuela, Peñas Blancas,  850 melevation, sifted fruit and flower fall, female,  18.5.1989, leg. J. Ashe, R. Brooks, R. Leschen ( KNHM).   Diagnosis: The species resembles  O. setosuscencerning the size and shape of the pronotum. It can be differentiated from that species by the asymmetric shape of the aedeagus and the evenly punctate head.   Description: Length: 6.5 mm. Colouration: Black; legs and antennae brown.  Head: 0.91 mmlong, 1.29 mmwide; eyes moderately large; as long as temples; sides of fore-head emarginate; anterior edge of clypeus even; setiferous punctation even; on average, interstices between punctures as wide as diameter of punctures; small area on central posterior vertex and at base of antennae impunctate; punctures close to neck partly granulate; netlike microsculpture weak; surface shiny.  Antennaeslightly longer than head; second antennomere globular; as long as third; following antennomeres four to seven approximately quadrate; antennomeres eight to ten slightly longer than wide.  Pronotum: 1.32 mmlong; 1.52 mmwide; widest at anterior angles; evenly narrowed to widely rounded posterior angles; anterior angles produced to short acute teeth; lateral margin fine; finer at anterior angles than at posterior angles; setiferous punctation dense and deep; narrow midline impunctate; interstices between punctures one fourth as wide as diameter of punctures; without microsculpture except remains of weak netlike microsculpture close to posterior margin; surface shiny.  Elytra: 1.53 mmlong, 1.44 mmwide; as densely and deeply punctate as pronotum, but setiferous punctures hardly visible in deep coriaceous ground-sculpture.  Abdomenwith sparser setiferous punctation than forebody; moderately wide midline on tergites impunctate; netlike microsculpture distinct.  Protibia: 0.92 mmlong, 0.27 mmwide; 8 long spines at outer edge; apical four spines inserted on moderately long digits; WLR: 0.8; in posterior aspect, comb of inner emargination visible throughout its total length; posterior face with moderately dense setation; on average, setae as long as half of protibial width.  Aedeagusrectangularly angulate; asymmetric; left side of apical lobe with moderately large basal plate; right side without central tooth; both sides of inner edge with few setae.   Etymology: The specific name refers to the dense setiferous punctation of the total body. 3447076306 1996-06-13 KNHM R.
