A review of Norwegian Gymnometriocnemus (Diptera, Chironomidae) including the description of two new species and a new name for Gymnometriocnemusvolitans (Goetghebuer) sensu Brundin Author Stur, Elisabeth Author Ekrem, Torbjorn text ZooKeys 2015 508 127 142 http://dx.doi.org/10.3897/zookeys.508.9874 journal article http://dx.doi.org/10.3897/zookeys.508.9874 1313-2970-508-127 AD0BD72FA2174ED5A84CAB381ED1E624 Taxon classification Animalia Diptera Chironomidae Chaetocladius volitans (Goetghebuer, 1940) comb. n. Metriocnemus volitans Goetghebuer, 1940: 59. Metriocnemus volitans Goetghebuer in Thienemann (1941 : 150, 172). Remarks. Several of the type specimens are quite damaged and many characters are difficult or impossible to observe (Figs 1-2). However, it is obvious that they do not belong to Gymnometriocnemus , and the better preserved male specimens show characters that fits the diagnosis of Chaetocladius : wings with coarse punctuation and without macrotrichia on the membrane (Fig. 1D), divergent lateral spinules on the tibial spurs (Fig. 1C) and a fore leg ratio of 0.75. We are confident that this species should be placed in Chaetocladius , but due to the state of the specimens and the unrevised nature of the genus, we have not attempted to compare Chaetocladius volitans with other species in Chaetocladius .
