Oxypoda (Deropoda) lencinai nov.sp. ( Figs 9-15 )

T y p e m a t e r i a l: Holotype: " E. Molina de Segura ( MU), El Rellano, 1.VI.- 15.VII.2000, J. L. Lencina leg., Trap Pit-Fall, Parque Ecologico Vicente Blanes, 38°13'6.02'' N, 1°13'5.47 O, 400 m. / Holotypus Oxypoda lencinai sp. n. det. V. Assing 2010 " (cAss).

D e s c r i p t i o n: Body length 3.0 mm. Habitus as in Fig. 9 . Coloration: body probably reddish, with abdominal segment VI infuscate; legs and antennae reddish-yellow. (The holotype is of somewhat dark-brownish coloration, but this is evidently a result of post-mortem darkening.)

Head approximately as wide as long; dorsal surface matt due to extremely dense and confluent punctation ( Fig. 10 ). Eyes large ( Fig. 11 ) and bulging, approximately twice as long as postocular portion in dorsal view. Antennae of moderate length and weakly incrassate apically; antennomere I approximately 1.5 times as long as broad; II about as long as I and twice as long as broad; III slightly less than twice as long as broad and slightly shorter than II; IV-X weakly transverse and gradually, but weakly increasing in width; X less than 1.5 times as wide as long; XI slightly longer than the combined length of IX and X. Maxillary palpus slender, preapical palpomere approximately 3.5 times as long as broad.

Pronotum 1.45 times as wide as long and 1.53 times as wide as head, maximal width approximately in the middle; posterior margin weakly sinuate between middle and posterior angles; dorsal surface matt due to very dense and confluent punctation ( Fig. 10 ).

Elytra slightly narrower than, and 0.75 times as long as pronotum; laterally weakly, but extensively impressed; lateral margin sharply carinate, this carina straight, distinctly elevated, and not depressed in the middle; posterior margin with small and not very deep concavity near posterior angles; punctation similar to that of pronotum ( Fig. 10 ). Hind wings reduced to short rudiments (slightly protruding beyond posterior margin of elytra). Legs slender, metatarsus almost as long as metatibia, metatarsomere I almost as long as the combined length of II-IV.

Abdomen widest at base and gradually tapering posteriad ( Fig. 9 ); tergites III and IV matt due to very dense and coarse punctation; punctation of tergites V-VII increasingly fine and sparse; posterior margin of tergite VII without palisade fringe.

: posterior margin of sternite VIII convex, not pointed in the middle; median lobe of aedeagus as in Figs 12-13 , apex of ventral process bifid, deeply incised in ventral view ( Figs 13-14 ); apical lobe of paramere moderately slender ( Fig. 15 ).

: unknown.

E t y m o l o g y: The species is dedicated to José Luis Lencina (Jumilla, Murcia), who collected the holotype, also in gratitude for the generous gift of numerous Staphylinidae collected with various trapping methods in Spain.

C o m p a r a t i v e n o t e s: Based on external and the male sexual characters (habitus, punctation, shape of legs, antennae, and maxillary palpi, large bulging eyes, the depressed and laterally carinate elytra, morphology of the median lobe of the aedeagus, long and slender apical lobe of the paramere), O. lencinai is most closely allied to O. magnicollis FAUVEL 1878 and O. arabs FAUVEL 1904 . It is distinguished from both by the shape of the aedeagus, from the former additionally by the darker coloration, the much more transverse pronotum, the shorter antennae, and the straight and more elevated lateral carinae of the elytra. It is separated from O. arabs particularly by much shorter antennae, distinctly shorter, flattened and extensively impressed elytra with pronounced lateral carinae, the shape of the median lobe of the aedeagus, and the less slender apical lobe of the paramere. Oxypoda (Deropoda) andalusiaca ASSING 2003 , whose distribution too is confined to southern Spain and which has reduced hind wings, has a much more slender body, distinctly smaller eyes, a weakly transverse pronotum, and longer elytra without impressions and without lateral carinae. For illustrations of O. arabs and O. andalusiaca see ZERCHE (1996) and ASSING (2003a), respectively.

D i s t r i b u t i o n a n d b i o n o m i c s: Thetypelocality is situated in Murcia, southeastern Spain, at an altitude of only 400 m. The reduced wings and the absence of previous records suggest the species has a restricted distribution and may live in a subterranean habitat.
