Adult male recognised by the remarkable form and colour of the mid tarsomeres. Female recognised by the absence of postpronotal setae, entirely pruinose katepisternum, and partly yellow legs; it is most similar to paludosa, but can be reliably distinguished by the characters given in the key (Pont and Meier, 2002, p. 53).
