Diagnosis (From Pont & Meier, 2002):

Adult orthocnemis can be recognised by the pattern of pruinosity on anepimeron, where a diagonal line separates the pruinose and shining areas, and in the male by the presence of two ventrally-directed and usually diverging spinules in apical third of fore femur.

(From Ozerov, 2005)
orthocnemis Frey, 1908: 583 (Sepsis). Type locality: Kangasala (FINLAND); Lectotype ♂, by designation of Pont in Pont and Meier, 2002: 176, in ZMUH.

(From Pont & Meier, 2002)
Sepsis orthocnemis: Frey described orthocnemis from both sexes, with the comment ‘wahrscheinlich ist diese Art ober ganz Finnland verbreitet’. It is now neither practical nor worthwhile to pinpoint his entire type-series, and for present purposes Pont regards as syntypes only those Finnish specimens in UZMH (University Zoological Museum, Helsinki, Finland) that are labelled by Frey himself as ‘types’.
A ♂ from Ta, Kangasala, R. Frey, seen by Pont, has been labelled and is herewith designated as lectotype; it is in excellent condition. Paralectotypes labelled by Pont are as follows (all in University Zoological Museum, Helsinki, Finland): one ♂, Ta, Birkkala, R. Frey; one ♂,Ib, Maaninga, Lundström; one ♂, Ks, Kuusamo, Mäklin; one ♂, Al, Saltvik, R. Frey; one ♀, Al, Sund, R. Frey. All these specimens are conspeci?c and belong to orthocnemis as currently understood.
