A review of Norwegian Gymnometriocnemus (Diptera, Chironomidae) including the description of two new species and a new name for Gymnometriocnemusvolitans (Goetghebuer) sensu Brundin.

Stur E, Ekrem T - Zookeys (2015)

Bottom Line: We present arguments for Chaetocladiusvolitans (Goetghebuer) comb. n. and for the use of Gymnometriocnemuskamimegavirgus for Gymnometriocnemusvolitans sensu Brundin.Two of these, Gymnometriocnemus (Gymnometriocnemus) pallidussp. n. and Gymnometriocnemus (Raphidocladius) autumnalissp. n. are regarded as new to science and diagnosed based on adult male morphology and DNA barcodes.The species Gymnometriocnemus (Gymnometriocnemus) marionensis Sæther, 1969 is re-established and a key to all Holarctic species is provided.

ABSTRACT
Examination of the syntypes of Metriocnemusvolitans Goetghebuer, 1940 revealed that these specimens belong to the genus Chaetocladius and are not con-specific with Gymnometriocnemusvolitans (Goetghebuer, 1940) sensu Brundin (1956) and Sæther (1983). A literature search showed that Gymnometriocnemuskamimegavirgus Sasa & Hirabayashi, 1993 fits well with the species figured and diagnosed by Brundin (1956) as well as with specimens of this species from Norway. We present arguments for Chaetocladiusvolitans (Goetghebuer) comb. n. and for the use of Gymnometriocnemuskamimegavirgus for Gymnometriocnemusvolitans sensu Brundin. In addition, we provide DNA barcode data that indicate the presence of at least seven Gymnometriocnemus species in Norway of which six are collected as male adults. Two of these, Gymnometriocnemus (Gymnometriocnemus) pallidussp. n. and Gymnometriocnemus (Raphidocladius) autumnalissp. n. are regarded as new to science and diagnosed based on adult male morphology and DNA barcodes. The species Gymnometriocnemus (Gymnometriocnemus) marionensis Sæther, 1969 is re-established and a key to all Holarctic species is provided.

Mentions: We have seen specimens from eastern and central Norway that fit well with the original and later descriptions of the species, except for having a lower AR (1.0-1.1) compared to what Edwards (1929) reported. The specimens group in a well-defined barcode cluster (Fig. 6) separated from Gymnometriocnemus (Gymnometriocnemus) marionensis and Gymnometriocnemus (Gymnometriocnemus) pallidus sp. n. and is fairly widely distributed throughout Europe.
