Aleochara (Xenochara) ultima LIKOVSKÝ, 1972 ( Figs 197-198)

Aleochara (Polychara) ultima LIKOVSKÝ, 1972: 164 f.

Type material examined:

Holotype ♂ [dissected prior to present study]: " Mongolia, Chovd aimak, Mongol Altaj Gebirge , cca 35 km N von Somon Uenč / Nr. 646, 8.VII.1966 / Holotypus 1970, Aleochara ultima Likovsky [curator label] / Holotypus Aleochara ultima m., det. Z. Likovský 1970 / Holotypus / Aleochara ultima Likovský , det. V. Assing 2009" ( HNHM).

Comment:

The original description is based on a single holotype male from " Chovd aimak: Mongol Altai Gebirge , cca 35 km N von Somon Uenč " ( LIKOVSKY 1972) .

Redescription:

Body length 4.0 mm. Coloration: head, pronotum, and abdomen blackish-brown, abdominal apex paler; elytra dark yellowish, with the anterior margin and the suture narrowly and diffusely infuscate; legs yellowish-brown; antennae dark-brown with antennomeres I-III yellowish-brown. Pronotum relatively small in relation to head, approximately 1.35 times as wide as long and 1.3 times as wide as head. Elytra approximately as long as pronotum. Metatarsus approximately 0.8 times as long as metatibia; metatarsomere I approximately as long as the combined length of II and III.

♂: posterior margin of tergite VIII broadly convex, in the middle weakly concave; sternite VIII posteriorly distinctly produced, in the middle almost acutely angled; median lobe of aedeagus as in Figs 197-198.

♀: unknown.

Comparative notes:

Based on external characters and the morphology of the aedeagus, this species refers to the A. sparsa group. It is distinguished from other species of this group particularly by the coloration, the relatively small pronotum, the long elytra, and by the shape and internal structures of the aedeagus.

Distribution:

Only the holotype from Mongolia has become known .
