Lusitanopsis segurica sp. n. ( Figs 5-7 , Map 1 )

Type material:

Holotype ♂: E - Castilla-La Mancha, Sierra de Segura , 20 km WSW Nerpio, 1490 m, 38°04 '02N, 02°30 ' 14W, 17.XII.2005, C. Andújar / Holotypus ♂ Lusitanopsis seguricasegurica sp. n. det. V. Assing 2007 (cAss) . Paratype ♂: same data as holotype (cAss) .

Description:

2.5-2.6 mm. Coloration uniformly reddish.

Head as in L. andujariandujari ( Fig. 5 ), but with antenna of different morphology ( Fig. 6 ): antennomere I larger, distinctly flattened, and of subrectangular shape; II large, almost as wide as I; antennomere III wider than long.

Pronotum of similar shape and relative size as in L. andujari ; dorsal rows composed of 5-6 punctures; area between these rows almost completely without microreticulation ( Fig. 5 ).

Elytra narrow, 0.90-0.95 times as wide and at suture 0.75-0.80 times as long as pronotum; shape (of both elytra combined) not distinctly transversely rectangular, lateral margins weakly convex in dorsal view; at humeral angles only with narrow rudiment of carina; humeral angles weakly marked ( Fig. 5 ); surface with distinct microreticulation and with sparse, relatively coarse punctures. Hind wings completely reduced.

Abdomen 1.15-1.20 times as wide as elytra, widest at segment VII; microsculpture of segments III-VII similar to that of L. andujari .

♂: aedeagus as in Fig. 7 .

Etymology: The name (adj.) is derived from the mountain range where the type locality is situated.

Comparative notes:

The new species is characterised especially by the shape of the aedeagus. From the preceding species, it is additionally separated by the morphology of the antennae, the differently shaped elytra (distinctly more slender and not of transversely rectangular shape), and the much less pronounced carinae at the weakly marked humeral angles (see description). For references to figures of the aedeagi of other endogean Osoriini occurring in the Iberian Peninsula see the comparative notes in the section on L. andujari .

Distribution and bionomics:

The type locality is situated in the eastern parts of the Sierra de Segura ( Map 1 ). The specimens were collected by soilwashing in a mixed forest with walnut and other deciduous trees near a stream at an altitude of almost 1500 m.
