( figs. 5–8)

Loc. typ.: Syria, NE Latakia, Slinfeh env., 1800 m asl .

Type series. HT ♂, Syria, NE Latakia, Slinfeh env., 1800 m asl, 27.5.1998, St. Kadlec lgt. (CVv) .

PTT: 2 ♂ ♂ 1 ♀, Syria, NE Latakia, Slinfeh env., 1800 m asl, 27.5.1998, St. Kadlec lgt. (CGi, CVa, CVv) .

Diagnosis. An Anemadus species of the strigosus species group (sensu Giachino & Vailati, 1993), based on the pronotum with wide base and disk granulose with emphasized microsculpture, elytral sculpture of type B (with transverse regular rows and longitudinal striae barely visible), parameres with apex curved outwards, internal sac of the aedeagus without specialized phanerae.

Anemadus kadleci n. sp. is close to A. arcadius Reitter, 1885 and A. whiteheadi Giachino & Vailati, 2001 in the body shape and structure of the aedeagus. The new species differs from A. arcadius in the shorter elytra, the narrower pronotal base, the shorter VI antennomere, the different shape of the apical part of the median lobe of the aedeagus, which is squatter, with lateral expansions differently shaped and the apex less spear-shaped. The new species also differs from A. whiteheadi by the shorter elytra, less parallel in the basal 1/3, the narrower pronotal base, by the shorter VI antennomere, by the different shape of the apical part of the median lobe of the aedeagus, which is squatter with larger lateral expansions and with longer, slightly spear-shaped apex, and by the apex of the parameres which in lateral aspect does not appear to be upwardly hooked. A. kadleci differs also from both the above-mentioned species in the longer parameres which, in lateral view, are much thinner, particularly in the apical part and, in dorsal aspect, have a truncate apex, and are slightly hooked outwards.

Description. Total length: 2.46–2.53 mm (♂ ♂), 2.38 mm (♀). Body from testaceous to reddish-brown with legs, antennae and palps slightly lighter and head and antennomeres III-XI slightly darker.

Body uniformly covered with short and semi-erect, yellow pubescence.

Head retractile, eyes well-developed, pubescence short and recumbent on the frons. Antennae short, thin, not reaching the basal 1/5 of elytra, VIII antennomere sub-quadrate. Antennomeres length (mm):

HT ♂ 0.130 - 0.123 - 0.109 - 0.068 - 0.089 - 0.054 - 0.082 - 0.047 - 0.085 - 0.071 - 0.150

PT ♀ 0.113 - 0.102 - 0.089 - 0.061 - 0.071 - 0.047 - 0.075 - 0.037 - 0.068 - 0.075 - 0.130

Pronotum transverse (ratio maximum width/maximum length: 1.76–1.86 ♂♂; 1.80 ♀) widest at base, without basal impression; lateral margin regularly curving anteriorly, posterior angles rounded. Base of pronotum as large as base of elytra, slightly sinuate laterally. Disk pubescence yellow, short and semi-erect. Pronotum disk granulose, with emphasized microsculpture.

Elytra elliptical, widest at basal fourth, not very elongate (ratio maximum width to maximum length: 0.64– 0.68 ♂ ♂, 0.68 ♀), each of them apically rounded, slightly rounded in the basal third. Elytral disk convex, flattened along the suture in the basal half, strongly separated apically. Sculpture of type B (sensu Giachino & Vailati, 1993). Sutural stria present, well-developed, sub-parallel to the elytral suture in the basal 2/3, strongly convergent in the distal third.

Metathoracic wings fully developed.

Legs relatively short, protibiae slightly expanded distally, with inner latero-ventral expansion in male. Mesotibiae curved, metatibiae slightly curved. Three basal segments of anterior tarsi dilated in male, narrower than the apex of the tibia.

Aedeagus ( figs. 6–7 ) large, very long, length 0.76 mm (0.83 if measured with parameres included). Median lobe dorsally stout, with lateral edges sinuate; basally strongly narrowed, distally extending, curved and converging towards the apex. Apical part setulose, ogival, with two pre-apical lateral expansions and a long spear-shaped apex. In lateral view dorsally bisinuate, with apical part sharply curved upwards and tip slightly bent ventrally.

Parameres ( figs. 6–8 ) dorsally strong, enlarged at the base and straight prior to the lateral expansions of the median lobe and subsequently curved inwards, thinning and with truncated, not hooked tips pointing outwards. In lateral view it appears apically thinning and not hooked dorsally. The setae are inserted apically and on the dorsal margin as in figure. Internal sac without sclerified phanerae, with two distal bladder-like sacs ending in a large spinular bundle, bifid in the basal half.

Female genitalia as typical for the genus.

Etymology. We would like to name this new and interesting species in memory of its collector, the Czech entomologist Stanislav Kadlec, eminent specialist of Palearctic Cerambycidae .

Distribution and ecology. A. kadleci sp. nov. is so far known only from the type locality: Slinfeh, at 1800 m a.s.l. in NE Latakia ( Syria). The new species was collected in May.

Concluding remarks. As already highlighted in the introduction, no new species of Anemadus have been described for the Mediterranean and the Near East since the records of Giachino & Vailati (1993, 2001). The faunistic and zoogeographic revision of Near Eastern Cholevidae by Giachino & Vailati (2000), in fact, only gives a synthesis and update of the chorology of the genus Anemadus . The description of two new species of this genus, belonging to two different species-groups, presented herein, helps to better define the distribution of this genus in the Near East.

A. lucarellii sp. nov. belongs to the pellitus species-group (sensu Giachino & Vailati, 1993). It was collected in the Toros Dağlari, a mountain range which hosts two further species of the same group ( A. cribratostriatus and A. ciamliyaylae ), which are morphologically very similar to A. lucarellii n. sp. ( fig. 9 ). As already recorded for A. ciamliyaylae , the only locality so far know for A. lucarellii n. sp. is located in the margin of the distribution range of A. cribratostriatus , leading us to consider A. lucarellii n. sp. to be a peripheral isolate. The origin of A. lucarellii sp. nov. and A. cribratostriatus from a common ancestor could be related to isolation phenomena at high altitude caused by recent climatic events, similarly to what has already been hypothesized by Giachino & Vailati (1993) for the other Anatolian species of this groups which presently have a puntiform distribution, i.e., A. ponticus (Vailati, 1984) , A. cavazzutii Giachino & Vailati, 1993 and A. ciamliyaylae Giachino & Vailati, 1993 .

A. kadleci sp. nov. belongs to the strigosus species-group (sensu Giachino & Vailati, 1993); it shows strong morphological affinities with two species from Southern Greece ( A. arcadius and A. whiteheadi ) and is known only from Latakia in Syria. The new species represents, with A. strigosus saulcyi Jeannel, 1936 (the validity of which as subspecies was questioned by Giachino & Vailati (1993)), the second species of this group in the Near East. The presence of a species of the A. strigosus- group in Syria strongly expands towards the East the distribution of the group ( fig. 9 ), which was so far known only for the western part of the Anatolian peninsula.
