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 : 735-736

( Figs 41‒46 )

Orthocladius (Dactylocladius) hockaiensis Goetghebuer, 1933: 289 .

Type material examined. LECTOTYPE (present designation): ♁ in isinglass, now mounted on slide, labelled: ‘ Orth. hockaiensis Hockai Hautes Fagnes 17.VI.1932 // type ♁ / M. Goetghebuer // R.I.SC.N.B. 18.073 / Coll. et det. M. Goetghebuer ”. PARALECTOTYPES: 2 ♁♁ in isinglass, now mounted on slide, with hypopygium only, same locality, except sampling date: 19. VI.32.

Redescription. Antennal plume well developed. Wing: squama (broken) without visible setae, with fine punctation, Cu

strongly curved. Pulvilli present. Virga very long and large, similar to the one observed in P. macrovirgatus Saether & Sublette, 1983 , but much longer, about 100 micron long.

Comments. ASHE & O’CONNOR (2012) listed Orthocladius hockaiensis among nomina dubia in Orthocladiinae ; the examination of type material shows that the species belongs to the genus Pseudorthocladius Goetghebuer, 1943 and does not fit with any other described species.
