Pont, Adrian C., 2012, Muscoidea (Fanniidae, Anthomyiidae, Muscidae) described by P. J. M. Macquart (Insecta, Diptera), Zoosystema 34 (1), pp. 39-111 : 71

longicornis Macquart, 1843 , Cleigaster

Cleigaster longicornis Macquart, 1843: 183 ( 1844: 340) , pl. 26, figs 3, 3a. Lectotype ♀, “ Sénégal ” ( Senegal), by present designation, in MNHN.

MATERIAL. — Macquart described this from ♀♀ from Senegal and île Bourbon (La Réunion), in MNHN and his own collection. Only 1 ♀ syntype has been located, under no. 999 of the Macquart collection in MNHN. No syntypes were found in the Macquart collection in MHNL or the Bigot collection in OUMNH. The MNHN syntype has an old white disc with “ Senegal / Guerin”, and Macquart’s label “Cleigastra [sic] / longicornis”. It is not in good condition, and in fact Séguy (1952: 6) described it as “un débris innommable”(“unidentifiable debris”). It is rather mouldy ; right antenna, left hind tarsomeres 4-5, right hind leg and abdomen missing; left eye eaten away. I have labelled it and designate it herewith as lectotype.

CURRENT IDENTITY. — Emden (1941: 254) did not see Macquart’s type but thought that the name might be referable to the muscid genus Anaphalantus Loew, 1857 . As he pointed out, Macquart’s description agrees with the single species of this genus but his figure does not. However, discrepancies between Macquart’s text and illustrations are easy to find: for example, he frequently described a ♀ in his text but showed a ♂ head in his figure. The figures were intended only to give a generalized representation of the appearance of a species rather than a precise delineation of its characters. Cleigaster longicornis does indeed belong to the genus Anaphalantus , and is an older name for Anaphalantus pennatus Loew, 1857 , as established by Pont (1980: 753).
