Anthelephila kadleci sp. nov.

( Figs. 1–5 )

Type locality. Yemen, Kawr Sayban mt., NW of Al Mukalla, 14°37′N 49°03′E, 575 m.

Type material. HOLOTYPE: J, ‘S YEMEN, Kawr Saybān mt. NW of Al Mukallā, 575 m, 14°37′N 49°03′E, 29.III.2007, S. Kadlec leg. [p]’ ( NMPC) . PARATYPES: 1 J, 2 ♀♀, same data as holotype ( ZKDC, 1 ♀ NMPC) ; 2 ♀♀, ‘S YEMEN Kawr Saybān mt. NW Al Mukāllā 575 m N14°37′ / E49°03′ (light) 29.III.2007 M. Rejzek [11] [p]’ ( ZKDC) .

Description. Male (holotype). Body length 3.6 mm. Head and pronotum dark brown, at places with reddish tinge; elytra dark brown with reddish base and vaguely indicated paired reddish posthumeral spot; legs brown, palpi brownish, antennae reddish in basal third, gradually darkening, with 3–4 apical antennomeres brownish.

Body form as in Fig. 1 . Head 1.4 times as long as wide, unevenly rounded posteriorly, somewhat produced postero-medially (posterior arch parabolic in dorsal view); tempora distinctly narrowing posteriad, their posterior angles absent; base clearly differentiated from short neck. Eyes conspicuously large, rather moderately convex. Dorsal surface glossy, corrugated in anterior half, with distinct longitudinal wrinkles along median margins of eyes, finely but distinctly punctate in posterior third (punctures otherwise somewhat obscured at corrugated places). Setation pale, subdecumbent, with a few slightly longer and rather inconspicuous erect setae. Antennae moderately enlarged in terminal third; antennomere X 1.7 times and antennomere XI 2.1 times as long as wide.

Pronotum 1.5 times as long as wide, narrower than head across eyes, nearly evenly rounded anteriorly, strongly narrowed posteriorly and moderately impressed postero-laterally in dorsal view; pronotal disc evenly shaped, its outline more or less convex in lateral view. Surface glossy, largely smooth, rugose to transversely corrugated postero-dorsally shortly before base, postero-lateral impressions shortly and finely wrinkled; dorsal median punctation similar to that on head. Setation as that on head.

Meso- and metaventrite simple.

Elytra elongate, twice as long as wide, conjointly rounded apically; humeri moderately protruding, rather rounded; postscutellar impression at most slightly indicated. Surface glossy, finely but distinctly punctate; basal half with punctures simple, evenly spaced, about as coarse but sparser than those on head. Setation pale, generally moderately longer than that on head, subdecumbent, with few, inconspicuous erect setae.

Metathoracic wings fully developed.

Fore legs modified ( Fig. 2 ); profemora with long and narrow process, flattened and rounded apically, with a dense row of short and stiff black setae on apical margin; protibiae slightly dilated and flattened on inner side at mid-length and with small rounded lobe on their outer side distally; penultimate tarsomere widened / flattened distally, with terminal tarsomere articulated dorsally in all tarsi. Setation normally developed.

Abdominal characters as in Figs. 3, 4 ; sternum III with pair of very slight, setose protuberances (or coarser punctures) shortly before posterior margin; tergum VII simple, evenly rounded posteriorly; paired prongs of sternite VIII bifurcate in apical half; apical portion of tegmen 0.4 times as long as basal piece, trilobed apically ( Fig. 5 ).

Female. For most external characters identical with male, except for simple front legs and sternum VII.

Variation. Body length (J ♀) 3.6–4.8 mm.

Differential diagnosis. Anthelephila kadleci sp. nov. undoubtedly belongs to the A. angustiformis species-group ( KEJVAL 2002). It appears to be very close to A. simoni (Pic, 1893) , as suggested by the similarity of some male abdominal characters (nearly simple abdominal sternum III, similar morphology of sternum VIII and bifurcate prongs of sternite VIII), however, it differs clearly in the characters of the front legs, that are modified in A. simoni as follows: profemoral process wide and short, tooth-shaped, lacking short stiff apical setae; protibiae with small pointed protuberance distally on inner side, otherwise simple, not impressed on inner side.

Etymology. Named in honour of the late Czech entomologist Stanislav Kadlec, specialist in Cerambycidae of the western Palaearctic Region and one of the collectors of this species.

Distribution. Yemen.
