Microhoria antalya Kejval , sp. nov.

( Figs 68, 70 , 136 )

Type locality. Turkey, Antalya Province, Manavgat env., alt. 150 m.

Type material. HOLOTYPE:, ‘TR – Antalya; 150 m Umg.Manavgat; Ges 30.XII.1990 ASSING [p] // Clavicomus angulifer (Pic) det. G. Uhmann 1992 [p+h]’ ( ZSMC).

Additional specimen. TURKEY: 1 ♀, Antalya prov., 22 km W of Alanya, Avsallar, 9.–23.v.1995, A. Pütz lgt. ( ZSMC).

Description. Male (holotype). Body length 3.2 mm. Body reddish-brown, head slightly darker, elytra with very vague paler markings ( Fig. 136 ); legs and antennae reddish.

Head nearly 1.2 times as long as wide, widely rounded posteriorly; eyes small, moderately convex. Surface moderately glossy, distinctly punctate; punctures distinctly spaced; setation short, subdecumbent to decumbent, with several short erect setae. Antennae only moderately enlarged in apical half; antennomeres X 1.3 times, XI 2.1 times as long as wide.

Pronotum 1.1 times as long as wide, moderately narrower than head including eyes, somewhat widely rounded anteriorly, pronotal disc evenly moderately convex, outline in dorsal view with lateral margins moderately impressed posteriorly. Surface moderately glossy, distinctly punctate; punctation distinctly coarser, setation as on head, with some short erect setae.

Elytra 1.7 times as long as wide; humeri inconspicuous; apices modified, distinctly produced medially, channel of gland very slight, situated near apex. Surface moderately glossy, distinctly punctate; punctation coarser, setation somewhat longer than on head, with scattered short erect setae.

Legs slender, simple; all tibiae with paired terminal spurs.

Abdominal sternum VII moderately produced and evenly rounded apically; sternum VIII forming simple, subtriangular paired sclerites, narrowly connected medially, rounded and setose posteriorly. Aedeagus ( Figs 68, 70 ): tegmen comparatively short and wide, straight, its apical portion somewhat flattened, straightly projecting, reinforc- ed medially and bluntly pointed; endophallic armature with paired row of densely spaced robust spines and pair of long, slender, bluntly pointed sclerites.

Female. Identical with male for most external characters; elytral apices simple, slightly produced and narrowly rounded; sternum VII simple; tergum VII simple, subtriangular, evenly rounded apically.

Variation. Body length (♀) 3.2–3.5 mm; body reddish to reddish-brown.

Differential diagnosis. Microhoria antalya sp. nov. belongs to the Microhoria longiceps species-group, having in general a similar armature of the endophallus as do most of the eastern Mediterranean members of this group. Considering their variation it may be difficult to recognize this species by its external characters; nevertheless, the following character set seems to be useful, at least for rough initial sorting: body reddish-brown, head base widely rounded, body punctation rather dense and distinct (especially on pronotum), setation of elytra moderately raised and uniform (setae rather evenly pointing posteriad), antennae comparatively long and slender. Major distinguishing characters of M. antalya sp. nov. are as follows: elytra evenly rounded postero-laterally and with prominent apical median protrusion (rather moderately angled in M. decolorata ); tegmen comparatively short and wide, straight in lateral view, its apical part moderately produced and somewhat flattened, straightly projecting ( Fig. 70 ), asetose and reinforced medially on ventral side (more convex and quite simple, moderately bent apically in lateral view in M. decolorata ( Figs 69, 71 ); strongly convex, widened and then abruptly narrowed, with transverse carina subapically on ventral side in M. gigas; extremely produced, flattened and apically rounded in M. angulifer ; for clearly different condition in M. truncata see Figs 72, 73 ).

Etymology. Named after the Turkish province Antalya where this species was discovered; noun in the nominative case, standing in apposition.

Distribution. So far known only from Antalya Province, southern Turkey.

Remarks. There is no serious doubt about the identity of the female examined. It is also from Antalya (about 30 km SE of Manavgat); however, it is preferable to leave the single female as a non-type specimen in this case.
