orthonevra Macquart, 1835   , Aricia  

Aricia orthonevra Macquart, 1835: 292   . Lectotype ♀, “du nord de la France ” ( France, Lille area ), by present designation, in MHNL.

MATERIAL. — Described from an unspecified number of unsexed specimens. Macquart (1850c: 532) recorded this species as present in the MHNL collection. There are 2 ♀♀ syntypes in MHNL, one of which was seen but not studied by Hennig (1964c: 1074). One is in box F of the Macquart collection. It is damp; both mid legs missing; abdomen fractured between segments 4 and 5. It stands over the drawer label “ A. orthonevra   / Macq. Lille”. I have labelled it and designate it herewith as lectotype. The 2nd ♀ is in the last (unnumbered) box of the Macquart collection. It is a fragmentary ♀, and has been almost completely devoured by beetle larvae. It is labelled “ A. orthonevra   / nob / L. [Lille]”. I have labelled it as paralectotype.

CURRENT IDENTITY. — Bezzi & Stein (1907: 649) and Hennig (1956: 135) have treated this name as a doubtful synonym of Mydaea urbana (Meigen, 1826)   . However, the lectotype is clearly identical with Mydaea detrita (Zetterstedt, 1845)   of Hennig (loc. cit.) and replaces this name ( Pont 1986b: 157; Gregor et al. 2002: 151). The paralectotype is also a species of Mydaea   Robineau- Desvoidy, 1830, but cannot be identified.

The lectotype has some of the aristal hairs broken off, but on one arista the hairs are as long as in typical Mydaea detrita   and not short as in Mydaea deserta (Zetterstedt, 1845)   , another similar yellow-legged species. In any case, the palpi are not swollen as they are in M. deserta   . As in some other material of M. detrita   that I have seen, the base of vein R 4 + 5 is bare above. Other features of the lectotype include prealar much longer than second notopleural seta, katepisternal setae 1 + 2, foretibia without submedian seta, basicosta and trochanters yellow.
