tibialis Macquart, 1839 , Lispe

Lispe tibialis Macquart, 1839: 116 . Lectotype ♂, locality not stated (from title: Canary Islands ), by present designation, in MNHN.

MATERIAL. — Described from an unspecified number of both sexes. I found 2 ♂♂ syntypes in the Collection générale in MNHN, and have transferred them to no. 369 of the Macquart collection. One of them is in perfect condition: I have labelled it and designate it herewith as lectotype. It is labelled by Macquart “N°. 89. / Lispa [sic] / tibialis”, and 89 is the serial number for L tibialis in Macquart’s paper. The 2nd ♂ has been labelled as paralectotype.

CURRENT IDENTITY. — Bezzi & Stein (1907: 681) and Hennig (1960b: 456) have treated L. tibialis as a junior synonym of Lispe tentaculata (De Geer, 1776) , and this synonymy appears to be correct. However, it cannot be ruled out that Lispe tibialis may be identical with Lispe draperi Séguy, 1933 , recently raised from the synonymy of L. tentaculata by Vikhrev (2011: 64). Dissection of the ♂ terminalia will be necessary to establish the identity of L. tibialis .

Becker (1904: 27) described a Lispe tentaculata var. canariensis , differentiating it from typical L. tentaculata principally by its dark palpi. Macquart specifically mentioned yellow palpi in his description, but in his specimens the palpi only appear yellow when held against the light. Their natural colour is brownish or brownish-orange, and even so they may have faded from an original dark brown. I do not think that the colour of the palpi, or of the tibiae, is a significant feature per se in L. tentaculata . Specimens that I have seen from 4000 m in the west Pamir Mountains ( Tajikistan) have palpi equally as dark as in Canary Islands ♂♂, even though the usual colour in this species is yellow.
