Magoga, Giulia, Montagna, Matteo, Marziali, Laura, Rossaro, Bruno & Disaa, 2017, Revision of type and non-type material assigned to the genus Orthocladius by Goetghebuer (1940 - 1950), deposited in the Royal Belgian Institute of Natural Sciences (Diptera: Chironomidae), Acta Entomologica Musei Nationalis Pragae (Acta. Ent. Mus. Natl. Pragae) 57 (2), pp. 723-749 : 738-739

Orthocladius corax (Kieffer, 1924)

( Figs 47‒52 )

? Orthocladius corax Kieffer, 1924: 65 .

Material examined. 1 ♁ in isinglass,now mounted on slide, labelled ‘ Orthocladius corax // locality Silésie 23.III.1944 // ex. coll. Bettinger, Belg. I. G. 12.595’.

Comments. ASHE & O’CONNOR (2012) listed Orthocladius corax Kieffer, 1924 among nomina dubia in Orthocladiinae . The bare eyes, the fine wing punctuation, squama with setae, presence of acrostichals, absence of pulvilli, the presence of an anal point rounded at the apex suggest inclusion of the species in Hydrobaenus Fries, 1830 .

The species appears to be valid based on specimens examined, however the material examined is non-type material, even if it comes from the type area (Silésie), but being collected twenty years later. At present it cannot be ascertained whether Goetghebuer’s identification of the RBINS specimen is correct or a misidentification of O. corax .
