Nitidula carnaria ( Schaller, 1783)

( Figs 1 , 4, 7, 10 )

Silpha carnaria Schaller, 1783: 257 ( Germany) . Nitidula quadripustulata Fabricius, 1792: 255 ( Germany) . Nitidula guttalis Herbst, 1793: 247 (locality unknown). Nitidula variata Stephens, 1830: 36 (locality unknown, presumably

Great Britain). Nitidula flavipennis Heer, 1841: 400 ( Switzerland) .

Material studied. We have studied over 450 specimens across the area of distribution (all NMPC). Here we provide precise data for new country records only: GEORGIA: 1 spec., Kakheti,Vashlovani National Park, Kaklis Kure Ranger Station, 41°17′06″N, 46°43′47″E, 166 m, on drying goat skin, 15.vi.2021, A. Lasoń leg. ( ALCB). PAKISTAN: 1 J, Northern Area, Aliabad, 2190 m, 36.3152N, 74.6483E, 4.vi.2007, G. M. Carpaneto leg. ( PACR). TAJIKISTAN: 1 spec., Babatak Mts. (Dushanbe), 18.iv.1980, J. Hladil leg. ( NMPC).

Diagnosis. Body length: 2.0– 4.4 mm. Body subparallel-sided, anterior margin of pronotum subtruncate, lateral margins of pronotum not explanate. Habitus similar to N. obenbergeri sp. nov., from which it differs in comparatively longer pronotum (ratio WPR2/LEPR = 1.41–1.57) and genitalia (cf. Figs 4, 7, 10 and 6, 9, 12 ). Spots on elytra less brightly coloured, pale yellow, pubescence of elytra either blackish or whitish yellow according to background ( Fig. 1 ). Antennae shorter than the width of head across eyes, antennomeres IV and V as a rule as long as wide. Apical margin of prosternal process broadly V-shaped. Male genitalia: Median lobe of aedeagus more than twice as long as wide, widest before its midlength and moderately narrowed both anteriad and posteriad, lateral margins in apical portion abruptly curved towards apex ( Fig. 4 ). Tegmen subparallel-sided, ca 1.5 × longer than wide, broadly rounded apically ( Fig. 7 ). Tergite VIII subtruncate apically ( Fig. 10 ).

Distribution. Widely distributed Palaearctic species; introduced to North and South America. First record from Georgia, Pakistan and Tajikistan.
