Kataev, B. M. & D. W. Wrase, 2006, Two new species of Selenotichnus KATAEV 1999 from Yunnan, China (Coleoptera, Carabidae, Harpalini), Linzer biologische Beiträge 38 (2), pp. 1493-1498 : 1493-1498

Selenotichnus klapkai nov.sp. ( Figs 1-3 )

T y p e m a t e r i a l: Holotype: 6: China, Yunnan, 10 km S Dali, 2000 m (meadow in small marble quarry), 26.V.2004, V. Klapka leg. (cWR). Paratype ♀: same data as holotype (cKL).

D e s c r i p t i o n: Body length 5.6-5.7 mm, width 2.4-2.5 mm.

Morphological character states as in S. olegi , but restricted and differing as follows.

Colour: Body black, slightly shining on dorsum, without a green tinge; outer margins of labrum and lateral beads of pronotum paler, dark ferruginous; palpi, antennae and tibiae brownish yellow, tibiae infuscate apically; femora dark, almost black.

Head: Medium sized (WHmax/WP = 0.64 in male and 0.63 in female; WHmin/WP = 0.50 in male and 0.52 in female), with moderately convex eyes. Clypeo-ocular prolongations very short, superficial. Labrum slightly concave at apex. Microsculpture visible on clypeus, above and behind eyes; meshes very fine, more or less isodiametric, a little more distinct in male than in female. Penultimate labial palpomere with four or five setae on anterior margin and one ventroapical seta.

Pronotum: Weakly and rather evenly convex, comparatively wide, 1.46-1.50 times as wide as long, widest just before middle, with evenly rounded sides. Base slightly wider than apex. Basal angles very obtuse, rather widely rounded at apices in holotype, somewhat distinct in paratype. Apical and basal beads complete, but border along apical margin slightly obliterate medially. Basal foveae small and shallow. Lateral depressions absent. Area between basal fovea and lateral margin somewhat flat. Base finely and densely punctate (puncturation in paratype slightly sparser than in holotype). Microsculpture visible almost throughout, distinct along margins, obliterate (particularly strongly in male) in central portion, consisting of more or less isodiametric meshes along base and of transverse meshes in other portions.

Elytra: Oval, in male 1.38 times as long as wide, 2.45 times as long and 1.21 times as wide as pronotum; in female these indices respectively 1.39, 2.49, and 1.20. Humeral angles blunt at apices, each with a small denticle visible from behind. Sutural angle sharp in male, narrowly rounded at apex in female. Each 3 rd interval with four to five small discal pores at 2 nd stria (pores at apex usually located at 3 rd stria). Microsculpture very distinct throughout, consisting of transverse meshes.

Legs: Fifth tarsomere with two, sometimes three pairs of latero-ventral setae.

Hemisternite and stylus: Similar to that of S. olegi .

Aedeagus: Median lobe ( Figs 1-2 ) robust, with a large basal bulb, arcuate, with apical portion clearly directed ventrad. Terminal lamella slightly wider than long, with sides roundly converging to narrowly rounded apex ( Fig. 3 ). Internal sac with a large tooth weakly curved and bearing a wide base, and with two large spiny patches dorsally.

C o m p a r i s o n s S. klapkai nov.sp. is very similar in external characters to S. olegi

1495

distinguished mainly by the more distinct dorsal microsculpture and the male genitalia with two large spiny patches in the internal sac. In addition, the terminal lamella of the median lobe of the new species is wider and stouter, and the pronotal disc between basal foveae and lateral margins is flatter.

D i s t r i b u t i o n: This new species is known only from the southern environment of Dali, the city in central Yunnan, located within the geographical range of S. olegi .

E t y m o l o g y: The latinized masculine form of the surname of the discoverer of the new species, Václav Klapka, to whom we dedicate it for his generosity.
