Oxypoda incurvata View in CoL nov.sp. ( Figs 61-63 View Figs 54-63 , 71-74 View Figs 64-75 , Map 4 View Map 4 )

T y p e m a t e r i a l: Holotype: "E - Andalusien, Sierra Nevada, Meybohm 24.2.2000 / N 37°7' W 3°27', westl. Str. zur Veleta, Bachtal, 1600 m / Holotypus Oxypoda incurvata sp.n. det. V. Assing 2008" (cAss).

D e s c r i p t i o n: Body length 3.4 mm. Habitus as in Fig. 61 View Figs 54-63 . Coloration: head blackish-brown; pronotum dark-brown; elytra brown; abdomen blackish-brown, with the apex (posterior 1/3 of segment VIII and segments IX-X) yellowish-brown; legs brownish; antennae completely dark-brown.

Head ( Fig. 62 View Figs 54-63 ) of subcircular shape and slightly wider than long; punctation moderately sparse and extremely fine, barely noticeable; interstices with distinct microreticulation; eyes large, but weakly convex, slightly longer than postocular region in dorsal view. Maxillary palpi slender, with the penultimate palpomere approximately 3.5 times as long as broad. Antennae long and slender, weakly incrassate apically; antennomere III almost as long as II; IV and V approximately as long as wide; VI-VIII weakly transverse; IX-X approximately 1.5 times as wide as long; XI conspicuously oblong, approximately as long as the combined length of VIII-X ( Fig. 63 View Figs 54-63 ).

Pronotum ( Fig. 62 View Figs 54-63 ) approximately 1.35 times as wide as long and almost 1.45 times as wide as head, widest slightly behind middle; posterior angles weakly marked; punctation very fine, but slightly more distinct than that of head; interstices with distinct microreticulation and subdued luster.

Elytra approximately 1.05 times as long and 1.2 times as wide as pronotum ( Fig. 62 View Figs 54-63 ); punctation dense and fine, much more distinct than that of head and pronotum; interstices with shallow microreticulation and subdued luster. Hind wings fully developed. Legs moderately long; metatarsus approximately 0.8 times as long as metatibia, the latter 0.4 mm long; metatarsomere I approximately as long as the combined length of II-IV.

Abdomen with lateral margins of segments III-VI subparallel, segments VII-VIII weakly tapering; punctation very fine and dense, slightly less dense on posterior than on anterior tergites; microsculpture distinct everywhere; posterior margin of tergite VII with palisade fringe; tergite VIII with convex posterior margin ( Fig. 71 View Figs 64-75 ).

: posterior margin of sternite VIII strongly convex, but not distinctly pointed in the middle; median lobe of aedeagus of distinctive morphology, ventral process long in relation to basal capsule, weakly curved and slender (lateral view); crista apicalis relatively small; internal sac with moderately long and almost straight flagellum, and with strongly bent apical sclerotised structures ( Figs 72-73 View Figs 64-75 ); apical lobe of paramere as in Fig. 74 View Figs 64-75 .

: unknown.

E t y m o l o g y: The name (Latin, adjective: curved) alludes to the shape of the apical internal structures of the aedeagus.

C o m p a r a t i v e n o t e s: This species is distinguished from the similar O. telifera , O. imminuta , and O. haemorrhoa particularly by the shape and internal structures of the median lobe of the aedeagus and additionally by the much longer and more slender antennae with a much more oblong antennomere XI, by the more transverse pronotum, and by the longer metatarsomere I.

D i s t r i b u t i o n a n d b i o n o m i c s: Oxypoda incurvata is known only from the type locality in the Sierra Nevada (Andalucía), which is identical to that of O. imminuta ( Map 4 View Map 4 ). The holotype was collected in a stream valley at an altitude of 1600 m.
