Systematics of New World Curtonotum Macquart (Diptera: Curtonotidae)

Abstract

The New World species of the curtonotid genus Curtonotum Macquart are reviewed, and all species outside the vulpinum and murinum species complexes (as defined below) are revised. Descriptions and illustrations are provided for 24 species, including 13 newly described species: C. adusticrus sp. n., C. atlanticum sp. n., C. bivittatum sp. n., C. brunneum sp. n., C. curtispinum sp. n., C. desperatum sp. n., C. papillatum sp. n., C. gracile sp. n., C. hunkingi sp. n., C. flavisetum sp. n., C. floridense sp. n., C. nigrum sp. n., and C. scambum sp. n. Curtonotum nigripalpe Hendel is proposed as a new junior synonym of C. hendelianum (Enderlein). A key to these New World species is presented and the phylogenetic relationships between them are discussed. Lectotypes are designated for C. tumidum Enderlein, C. bathmedum Hendel, C. taeniatum Hendel, C. trypetipenne Hendel, C. impunctatum Hendel, 1913, nec impunctatum Hendel, 1932 and C. apicale Hendel. Curtonotum perplexum nom. n., is given as the replacement name for C. impunctatum Hendel, 1932 nec impunctatum Hendel, 1913. Two species complexes are left untreated at the species level (the C. murinum species complex, including C. murinum Hendel, C. coriaceum Hendel, C. perplexum nom. n., and C. decumanum Bezzi; and the C. vulpinum species complex including C. vulpinum Hendel and C. fumipenne Hendel). Both complexes are included in the phylogenetic analysis and key.

A Revision of Afrotropical Quasimodo Flies (Diptera: Schizophora; Curtonotidae). Part III — the Malagasy Species ofCurtonotumMacquart, with Descriptions of Six New Species

“…Séguy, 1938, Tigrisomyia Kirk-Spriggs, 2010and Curtonotum Macquart, 1844, all of which occur in the continental Afrotropical Region; Tigrisomyia exclusively so. Curtonotum is the most speciose genus and is found in all zoogeographical regions of the world except Australasia/Oceania and Antarctica, although Klymko and Marshall (2011) point out that Curtonotum in its current broad sense is paraphyletic with respect to Axinota, and suggest restricting the name Curtonotum to a monophyletic New World group. Two genera are known to occur on Madagascar, Axinota, represented by a single species, A. kyphosis Kirk-Spriggs, 2010, of supposed Oriental origin and Curtonotum (Appendix I).…”
