( Fig. 21 View FIGURES 15 – 23 )

Coelostoma turnai Hebauer, 2006: 3 View in CoL .

Type material: not examined.

Material examined. HUNAN: 1 male, 30 km N of Dayong, Yanjiejie, 27–29.v.2005, Oto Nakládal leg ( NMPC).

Diagnosis. Body size 4.5–5.0 mm. Prosternum finely carinate medially, with fine dentiform process anteromedially. Head, pronotum and elytra with similar punctation; elytra with lateral portion more strongly punctate, without traces of series of punctures laterally. Mesofemora densely pubescent except at extreme apex. First abdominal ventrite with recognizable median carina basally; fifth ventrite emarginate and with a row of stout setae apically. Aedeagus ( Fig. 21 View FIGURES 15 – 23 ). 1.0 mm long. Median lobe bottle-shaped with apex very deeply excavated (bilobed); gonopore situated basally, transversely oval; parameres slightly shorter than median lobe, sinuate on outer face subapically, apices truncate.

Remarks. When Hebauer (2006) originally described this species from Hubei, he stated that the prosternum is not carinate but bears a fine dentiform process anteromedially. The examined specimen from Hunan precisely agrees with the original description in all other characters including the morphology of the aedeagus and moreover also comes from southeastern China. We therefore assign it to C. turnai , despite the fact that its prosterum is finely carinate.

Biology. Unknown.

Distribution. China (Hubei, Hunan) (Hebauer 2006, this paper).
