Malthinus egadiensis sp. nov.

( Fig. 7 )

Malthinus scapularis Marseul, 1978 : WITTMER (1971a): 181.

Type locality. Italy, Egadi Islands, Marettimo.

Type material. HOLOTYPE: J, ‘[ Italy], I.[slands] Egadi, Marettimo, 3.–12.v.[19]68, Godenigo [lgt.], [white label, handwritten] // Malthinus scapularis Mars. , det. W. Wittmer [white label, printed and handwritten]’ ( NHMB).

Description. Coloration. Head including antennae black, mouthparts sepia. Prothorax sepia, anterior margin, anterior and posterior corners and posterior margin somewhat paler. Meso- and metasternum, ventral part of abdomen and legs chestnut brown. Scutellum and elytra chestnut brown, apex of each elytron with lemon-yellow spot.

Male. Eyes of medium size, protruding; head across eyes about one fifth wider than pronotum, temporal margins straightly narrowing posteriorly; surface of head imbricate-punctate, finely brown pubescent, matt. Antenna long, moderately exceeding elytral apex. Pronotum moderately wider than long, anterior margin nearly straight, anterior corners obtusely rounded; lateral margins arcuate, sinuate before posterior corners; posterior corners almost rectangular, hardly rounded, posterior margin widely rounded; surface of pronotum sculptured and pubescent similarly to head, matt. Elytra finely rugulose-lacunose, finely brown pubescent, semilustrous in basal third, rest of elytra matt. Aedeagus as in Fig. 7 .

Female unknown.

Length (J): 4.5 mm.

Differential diagnosis. Malthinus egadiensis sp. nov. is similar to M. gratiosus Pic, 1901 ( Greece: Samos Island) in the shape of the apex of the ventral portion of the aedeagus. It differs from the latter in narrower and almost entirely parallel laterophyses and different shape of the phallus (cf. WITTMER 1971a). WITTMER (1971a) supposed that this specimen belongs to M. scapularis , described from Malta. An examination of Maltese material, however, showed that M. scapularis is a different species, described by WITTMER (1971a) as M. pseudoscriptus ( ŠVIHLA & MIFSUD 2006) .

Etymology. Named according to its type locality.

Distribution. Italy: Egadi Islands (near western coast of Sicily).
