( Figs 7–12 )

Orthocladius scaturiginis Goetghebuer, 1940: 62 .

Type material examined. Orthocladius scaturiginis : HOLOTYPE: ♁ stored in isinglass, now mounted on slide, labelled: ‘ Orthocladius scaturiginis n. sp. // type ♁ Goetghebuer // type locality environ d’Abisko en Laponie Suédoise, Thienemann, 1939 // R.I.SC.N.B. 18.073 / Coll. et det. M. Goetghebuer’.

Comments. Orthocladius scaturiginis was listed among nomina dubia in Orthocladiinae by ASHE & O’CONNOR (2012). The holotype male is not well preserved but can be identified as a Georthocladius because of the presence of acrostichals and pulvilli ( SAETHER & SUBLETTE

1983); only one broken antenna is present. The species is similar to Georthocladius platystylus Saether & Sublette, 1983 .
