Two new species of Rohdendorfia (Diptera: Syrphidae) from Central Asia

Abstract

<jats:title>Abstract</jats:title> <jats:p>Two new species of the flower fly genus <jats:italic>Rohdendorfia</jats:italic> Smirnov, 1924 (Diptera: Syrphidae) are described, <jats:italic>Rohdendorfia bella</jats:italic> Mengual, sp. nov. and <jats:italic>Rohdendorfia khakimovi</jats:italic> Barkalov, sp. nov. A full description and images of both new species are given, as well as an identification key for the species of this genus. Molecular sequences from mitochondrial cytochrome c oxidase I (COI) gene and nuclear ribosomal 28S and 18S rRNA genes are also provided for the new species. The studied specimens of <jats:italic>Rohdendorfia bella</jats:italic> Mengual, sp. nov. are the first record of the genus <jats:italic>Rohdendorfia</jats:italic> from India and represent the first individuals collected in the state of Jammu and Kashmir.</jats:p>

Phylogenetic relationships of the bacchine flower flies (Diptera: Syrphidae) based on molecular characters, with a description of a new species of Melanostoma (Schiner, 1860)

“…Eocheilosia has globular surstyli and sickleshaped postgonites, and Syrphocheilosia claviventris (Strobl, 1910) has one-lobed surstyli and elongate, one-lobed postgonites. Spazigaster ambulans (Fabricius, 1798) has sickleshaped postgonites but one-lobed surstyli, while Rohdendorfia species have one-lobed, sickle-shaped surstyli curved ventrally, and bilobed postognites with dorsal lobe hookshaped (Mengual & Barkalov, 2019). Pyrophaena rosarum (Fabricius, 1787) has sickle-shaped postgonites but broad, elongate, one-lobed surstyli.…”

New species of Myolepta Newman, 1838 (Diptera, Syrphidae) from the Indomalayan Realm

“…The Indomalayan flower flies are clearly understudied. Recent taxonomic revisionary works brought to attention this fact by the high number of new species discovered (Mengual & Ghorpadé 2010;Mengual 2012Mengual , 2016van Steenis & Hippa 2012;Thompson 2013Thompson , 2015Thompson , 2017aThompson , 2017bThompson , 2020van Steenis 2014;Hippa et al 2015;van Steenis et al 2018van Steenis et al , 2019Mengual & Barkalov 2019;van Steenis & Wyatt 2020;Sankararaman et al 2022;among others). The syrphid fauna of all major biogeographic realms are covered by published Manuals of Diptera (Vockeroth & Thompson 1987;Thompson & Rotheray 1998;Thompson et al 2010;Ssymank et al 2021) and unpublished revisionary works by F.C.…”
