Afrotropical Asilinae (Asilidae): A provisional key to genera, with a review of the status of Neomochtherus Osten Sacken, 1878, and descriptions of new genera and species Author Londt, Jason G.

Heligmoneura neavii Ricardo, 1919: 76–77 . Neomochtherus neavei ; Hull, 1962: 591 ; Tsacas, 1969: 26–27. Tsacasiella neavei ; Lehr, 1996: 73. Note: neavii is an incorrect spelling of neavei (see below). Type material: Syntypes : ZAMBIA : 1ơ 1^ [seen], ‘Type’, ‘NE Rhodesia . / Vy [= Valley] of Chambezi. [ 10 ° 16'S : 33 ° 01'E ] / 4,000 ft. / 16.v.1908 (^) 18.v.1908 (ơ) / S.A. Neave’, ‘ Syntype / Heligmoneura / neavei Ricardo / det. J.E. Chainey, 1985’ (BMNH); Syntypes : 1ơ 2^ 1? [not seen], Lualaba River [two sets of co-ordinates available 14 ° 02'S : 27 ° 50'E & 12 ° 46'S : 25 ° 46'E . Note: not ‘Sualaba’ as cited by Ricardo], 2500– 4000 ft , 19.iv.1907 , S. E. Neave (BMNH). Syntype : DR CONGO : 1ơ [not seen], Kambove, Katanga (BMNH). Lectotype designation: Ricardo (1919) did not designate a holotype and so I consider all her material to be syntypes . Should a lectotype desination ever be considered necessary, the male ‘type’ would be the most suitable specimen. While I have not seen Ricardo’s material from Sualaba River, and do not know how many specimens there are, these must also be considered syntypes . At least one of Ricardo’s ‘males from Kambove, Katanga , 4000–5000, 2.4.07, (S. A. Neave)’ (BMNH), also originally a syntype of neavei , is now the holotype of T. instabilis (Tsacas, 1969) . John Chainey (BMNH) has informed me that there is 1ơ syntype of neavei from Kambove in the BMNH. Although this is presently considered a syntype of neavei it is still necessary to determine if this specimen should also to transferred to T. instabilis . Material examined: Those indicated above as having been seen. Material not studied: Tsacas (1969) includes ‘ Congo ( Kinshasa )’ in his section on geographical distribution. I am, however, unable to confirm this information. T. futilis is also known from Kinshasa and so some confusion may exist . Type locality: Zambia , Chambesi. Comments: Ricardo’s (1919) original published spelling of the specific name was neavii . However, all subsequent authors correctly used the spelling neavei . No new specimens were found during the study.
