Anichtchenko, Alexander, 2014, Two new species of genus Singilis Rambur, 1837 (Coleoptera: Carabidae: Lebiini) from Namibia, Baltic Journal of Coleopterology 14 (2), pp. 137-140 : 138-140

Singilis (Protosingilis) bulirschi sp.n.

Type material. Holotype: Male - South Namibia, Karas, S slope of Namuskluft , 21.IX. 2013. 1035m, 27°52’596S, 16°52’753E (cPB, DUBC, MRAC).

Diagnosis. Among the seven species comprising the subgenus Protosingilis , S. (P.) bulirschi sp.n. is uniquely diag-nosable by its uniformly brownish body coloration. Most similar in overall appearance and size to S. (P.) muelleri Anichtchenko, 2012 , but with less transverse and cordate pronotum.

Description. Length 5 mm. Uniformly brownish yellow, with no dark elytral pattern ( Fig. 2 ).

Head smooth, distinctly microsculptured, very sparsely and minutely punctulate, punctures sometimes barely visible. Clypeus and labrum distinctly microsculptured. Eyes moderately large. Second supraocular seta located immediately basad the posterior margin of the eye. Temples long, smooth. Scape with a very long subapical seta and several small setae; pedicel and antennomere III each with a single band of apical setae. Antennae pubescent from the 1/3 of antennomere IV. Apical labial palpomere strongly securiform ( Fig. 6 ).

Pronotum smooth, cordate, 1.22 times as wide as head, 1.4 times as wide as long, widest near marginal setae. Anterior margin straight, anterior angles effaced, sides broadly and regularly rounded, strongly sinuate towards base, posterior angles acute, prominent. Disc impunctate. Lateral margin rapidly widened behind marginal setae, wide and flat towards base. Posterior pore close to angle. Basal grooves shallow. Pronotal base extended in a rounded median lobe. Microsculpture subtle, transversely polygonal.

Elytra suboval, 1.42 times as long as wide, moderately convex, with polygonal microsculpture. Anterior discal pore in elytral stria 3, median and posterior pores in center of interval 3. Elytral apices truncate, weakly and obliquely sinuate, rounded at suture. Striae very finely punctate. Intervals impunctate. Scutellum microsculpture as on elytra.

Legs pale brownish yellow. Tarsomere V with 3 pairs of short ventral setae. Claws with 3 minute denticles. Abdominal sterna smooth, shiny. Propleuron, mesepisterna and metepisterna smooth.

Aedeagus ( Fig. 4 ). Median lobe apex elongate, slightly downturned. Internal sac without apparent spicules or microtrichial patches.

Name derivation. Named after my friend and colleague, Dr. Petr Bulirsch ( Czech Republic).

Distribution. Namibia.
