Orthocladius (Symposiocladius) lignicola Kieffer 1914

Orthocladius (Symposiocladius) lignicola Kieffer, 1914 Orthocladius lignicola Kieffer, 1914 in POTTHAST (1915: 273). Material examined. 2 ♁♁ pinned, now mounted on slides, labelled: ‘ Orthocladius lignicola K. // R.I.SC.N.B. 18.073 / Coll. et det. M. Goetghebuer’, type locality not given. Comments. The differences between the species described in the subgenus Symposiocladius Cranston, 1982 (SAETHER 2004) are really small and the two RBINS specimens are in poor condition, with some body parts missing. Nevertheless, the hypopygeal structure confirms that the specimens belong to Symposiocladius and the length ratio of Pm 3 / Pm 4 = 114 / 78 (about 1.5) supports the identification of O. (S.) lignicola.
