Delina nigrita ( Fallén, 1819)

Cordylura nigrita Fallén, 1819: 10 . SYNTYPES: J ♀, Sweden, ‘Lärketorp Ostrogothiae [= Östergötland]’ (probably MZLU).

Delina tibialis Robineau-Desvoidy, 1830: 669 . SYNTYPES: J ♀, France, ‘à Paris et à Saint-Sauveur [= in Paris and in Saint-Sauveur]’ (depository unknown). Synonymized by HENDEL (1930b: 9).

Delina dejeani Robineau-Desvoidy, 1830: 670 .? SYNTYPES:? France, ‘doit être d’origine française [= should be of the French origin], [...] fait partie de la collection du comte Dejean [= in the collection of count Dejean]’ (current depository unknown). Synonymized by VOCKEROTH (1965: 841).

Cordylura erythrocephala Meigen, 1838: 340 , syn. nov. HOLOTYPE: J, ‘Mann. [= male]’, type locality not given (depository unknown).

Note. All characters of C. erythrocephala are within the limits of variability of D. nigrita and I therefore consider C. erythrocephala as a junior synonym of D. nigrita .

Lissa cornuta Waker, 1849: 1047 .? SYNTYPES: Canada, Ontario; no additional data quoted in the original paper (CNC). Synonymized by VOCKEROTH (1965: 841).

Chirosia cepelaki Teschner, 1978: 911 , syn. nov. HOLOTYPE: J, Slovakia, ‘ M. Fatra, Stoh. poľ. [= Malá Fatra Mts. , Stoh Mt., Stohové poľany mountain meadows], 20.vi.1973, Čepelák leg.’ (ZMUH, registration number ZHM 4/75).

Note. Chirosia cepelaki was originally described in the family Anthomyidae ( TESCHNER 1978:911) . MICHELSEN (2007: 504) wrote: ‘[…] I find it safe to conclude that Chirosia cepelaki Tescher [sic!] and Delina nigrita (Fallén) sensu Šifner are identical species [...] The Czech and Slovak species considered by ŠIFNER (2003) as Delina nigrita (Fallén) is evidently a misidentification’. I agree with MICHELSEN’ s (2007) opinion that C. cepelaki is identical with Delina nigrita sensu ŠIFNER (2003) . Howerer, I do not agree with the statement that D. nigrita sensu Šifner is misidentified. The figures of the male of Delina nigrita (Fallén) (cf. ŠIFNER 2003: 64, figs. 306-308) are based on a male labelled ‘Helsingfors, 23.iii.1939, Lindb., Delina nigrita (Fallén) , det. W. Hackman’ (FSPC), which were compared with the specimens from the Czech Republic; all male specimens from the Czech Republic are identical. The figure of female (cf. ŠIFNER 2003, fig. 309) is based on a specimen labelled ‘ Slovakia, Malá Fatra Mts., Štefanová, Stoh.[ové] poľany, 17.v.1975, Šifner leg.’, coming from the type locality of C. cepelaki . According to MICHELSEN (2007) the ‘true Delina nigrita is a smaller species without spinules on the postpronotal lobes with only two katepisternal setae’. Howerer, the presence of three katepisternal setae is an important character of the genus Delina (cf. also TESCHNER 1978: 912, fig. 2), which made his identification of D. nigrita doubtful. I regard C. cepelaki as a junior synonym of D. nigrita . Moreover, Stohové poľany are two submountain meadows on the Stoh Mt. above the valley of the Stoh brook, approximately 1,000 m a.s.l. In 1975, the locality had a large growth of Veratrum album , which should be the host plant of D. nigrita .
