Lusitanopsis meybohmi sp. n. ( Figs 8-10 , Map 1 )

Type material:

Holotype ♂: N37°53 ', W006°46 ', E Andalusien, Sierra de Aracena , 910 m, Meybohm, 5.4.2001 / Holotypus ♂ Lusitanopsis meybohmi sp. n. det. V. Assing 2007 (cAss) .

Description:

2.1 mm. Coloration reddish brown, legs and antennae dark yellowish.

Head as in L. andujari , but with pronounced microreticulation everywhere ( Fig. 8 ) and antenna of different morphology ( Fig. 9 ): antennomere I larger, distinctly flattened, and of subrectangular shape; II distinctly narrower than I; size of VI intermediate between that of V and VII, i. e. antennal club less distinctly separated from base of antenna.

Pronotum approximately as wide as head and 1.15 times as wide as long; anterior 2/3 of lateral margins subparallel and posterior 1/3 distinctly converging ( Fig. 8 ); dorsal rows composed of

approximately 5 punctures; area between dorsal rows with pronounced microreticulation (similar to that of lateral parts).

Elytra of similar shape as in L. andujari , 0.93 times as wide and 0.65 times as long as pronotum, and of transversely rectangular shape ( Fig. 8 ); whole length of lateral margins finely carinate (visible also when viewed from above); surface with shallow, but distinct microsculpture and rather fine puncturation. Hind wings completely reduced.

Abdomen 1.13 times as wide as elytra, widest at segment VII; microsculpture of segments III-VII similar to that of L. andujari .

♂: aedeagus as in Fig. 10 .

Etymology: The species is dedicated to Heinrich Meybohm, Grosshansdorf, who collected the holotype while looking for Scydmaenidae .

Comparative notes:

Lusitanopsis meybohmimeybohmi is distinguished from its congeners especially by the shape of the aedeagus. From the two preceding species, it is additionally separated by the pronounced microsculpture in the central dorsal area of the head and in the area between the dorsal rows of punctures on the pronotum, the antennal morphology (see description above), the shape of the pronotum (lateral margins abruptly converging in posterior 1/ 3 in dorsal view), and the long fine carina at the lateral margins of the elytra. From L. segurica , it is also distinguished by the broader and transversely rectangular elytra.

Distribution and bionomics:

The holotype was discovered near the Mirador San Cristobal in the Sierra de Aracena (Huelva, near Cortegana in western Andalucía) by sifting soil in the shade of big rocks at an altitude of 910 m (MEYBOHM pers. comm.) .
