The genus Aphasmaphleps Grichanov, gen. n. is described from Senegal to accommodate a new species, A. bandia sp. n. The new genus has been placed in the subfamily Diaphorinae and is considered close to the genus Phasmaphleps Bickel, 2005. A key to Afrotropical diaphorine genera of long-legged flies is compiled, and characters of the new genus are discussed.

The systematics of Alternaria and allied genera traditionally has been based on the characteristics of conidia and the sporulation apparatus. This emphasis on morphology in the reconstruction of organismal relationships has resulted in taxonomic uncertainty and flux for a number of taxa in Alternaria and the related genera Stemphylium, Embellisia, Nimbya and Ulocladium. The present study used a molecular phylogenetic approach for systematic resolution and incorporated extensive taxon sampling (n 5 176 species) representing 10 genera and analyses of 10 protein-coding loci. Phylogenetic analyses based on five of these genes revealed eight distinct asexual lineages of Alternaria that cluster as the sister group to the asexual paraphyletic genus Ulocladium, while taxa with known teleomorphs currently circumscribed as Alternaria (the infectoria species group) cluster among genera that also have representatives with known teleomorphs. This work proposes to elevate the eight well supported asexual lineages of Alternaria to the taxonomic rank of section. Evolutionary relationships among Alternaria and closely related genera are discussed. © 2013 by The Mycological Society of America.

Two new long-legged fly species Campsicnemus capellarii sp. n. and C. uttarakhandicus sp. n. from Uttarakhand, India, are described and illustrated. The following recombinations (comb. nov.) are proposed: Chaetogonopteron glaucum (Becker, 1924), Chaetogonopteron intermittens (Becker, 1924), Chaetogonopteron obscuratum (Becker, 1924). New data on the distribution of dolichopodid species in the Assam, Goa, Gujarat, Meghalaya, Orissa, Uttarakhand and West Bengal states of India are presented. Argyrochlamys impudicus Lamb, 1922, and Phoomyia srilankensis Naglis and Brooks, 2013, are recorded from India for the first time. © IGOR YA. GRICHANOV.

Among several groups of small-spored Alternaria species, A. sect. Alternaria (containing the generic type) has been found to be isolated, based on phylogenetic as well as morphological data. Molecular phylogenetic data confirm inclusion of twenty-one species in this section besides the type species. Examination of additional material, conforming to the morphological description for the section but not as yet phylogenetically characterized, allow confirmation of an additional 37 species. All 59 species are listed, and an emended description of Alternaria sect. Alternaria is presented. © 2015. Mycotaxon, Ltd.

Two new species, Cryptophleps namibica sp. nov., from Namibia and C. buttikeri sp. nov., from Saudi Arabia are de-scribed. The following new combinations are proposed: Cryptophleps izia (Negrobov, 1973) (Asyndetus), comb. nov. (Central Asia), Cryptophleps minuta (Negrobov & Shamshev, 1986) (Asyndetus), comb. nov. (Far Eastern Asia) and Cryptophleps vivida (Negrobov & Shamshev, 1986) (Asyndetus), comb. nov. (Far Eastern Asia). The systematic positions of species of Cryptophleps are discussed. An identification key to Afrotropical and Palaearctic species is provided. Copyright © 2015 Magnolia Press.
