A New Species of the Genus Otites (Diptera, Ulidiidae) from Crete (Greece)
Otites cretana Kameneva sp. n. from Crete (Psiloritis Ridge) is described. It superficially resembles Otites nebulosa (Latreille, 1812) and Dorycera persica Hennig, 1939 in the combination of very high gena and short antenna, but differs from all known Otitini by the thickened costal vein (in male), undulate vein R2+3, lacking ocellar setae and having 3 pairs of short scutellar setae. Status and generic limits of Otites and Dorycera are preliminary discussed.
A Peculiar New Species of the Genus Ulidia (Diptera, Ulidiidae) from Middle Asia
Ulidia metope Kameneva, sp. n. from Kyrgyzstan and Uzbekistan is described. It differs from all known species of the genus Ulidia Meigen by sexually dimorphic, broadly silvery white microtrichose sides of frons and parafacials resembling that in the flies of the genus Metopia Meigen (Sarcophagidae).
New and Little-Known Ulidiidae (Diptera, Tephritoidea) from Europe
New and Little-Known Ulidiidae (Diptera, Tephritoidea) from Europe. Kameneva E. P. — Improved keys to European species of Tetanops and Ulidia are provided. The shape of projections of the phallus glans is found to be essential to distinguish species in the genus Ulidia. Ulidia erythrophthalma (Meigen, 1826), U. albidipennis Loew, 1845, U. nigripennis Loew, 1845, U. parallela Loew, 1845 and U. atrata Loew, 1868 are shown to be separate species and redescribed with the use of genitalic characters. The following synonymy is established: Homalocephala albitarsis Zetterstedt, 1838 = Ortalis diopsides Walker, 1849, syn. n. = Ortalis costalis Walker, 1849, syn. n. Homalocephala apicalis (Wahlberg, 1838) = Psairoptera biseta Frey, 1909, syn. n. = Psairoptera similis Cresson, 1924, syn. n.; Homalocephala mamaevi Krivosheina et Krivosheina, 1995 is recorded for the first time from Europe (Austria, Sweden). Euxesta stigmatias Loew, 1873 is recorded for the first time in the Palaearctic Region based on a single unintentionally introduced specimen from Bulgaria. New finds of other ulidiid species in European countries are listed. Several species previously known only from Europe are recorded from Asia.
A New Species of the Genus Cymatosus (Diptera, Ulidiidae) from Central America, with a Key to Species
Cymatosus icarus Kameneva, sp. n. from Costa Rica is described. It differs from the four previously described species by the wing pattern with an additional arcuate hyaline stripe parallel to the wing margin, and a rounded brown spot in the middle of the wing disc, resembling that in Callistomyia icarus Osten Sacken (Tephritidae). A key to the species of the genus Cymatosus Enderlein and notes on other species are provided.
Herina caribbeana Kameneva, sp. n. from Dominica is described and figured. It is related to the narytia group of species, to date represented by 4 North American species, but differs from these by the wing pattern (dark spots at apex of R1 and on the crossbands r-m and dm-cu separated, not forming crossband), as well as male genitalia (prensisetae long and close together). This is the first record of the genus Herina Robineau-Desvoidy, 1830 from the Neotropical Region. A key to the New World species is provided.
Herina arjunae Kameneva, sp. n. from mountain grasslands on volcano Arjuna (at 2000 m a. s. l.) is described and figured. It is closely related to H. orientalis (Schiner, 1868) in the very similar position of crossveins on the wing, structure of female aculeus and spermathecae, but differing by its well-developed wing pattern with brown subbasal and apical bands, and with crossvein dm-cu brown emarginated (lacking in H. orientalis). Diagnosis and key to species of Herina orientalis group are provided.
A preliminary list of the picture-winged flies known from Columbia is supplemented by 15 species based predominantly on the materials from the National Museum of Natural History, Washington, D.C., USA and now contains 28 species, including Xycores igniceps gen. & sp. n. from Venezuela and Colombia. The new genus belongs to the subfamily Otitinae and is preliminarily assigned to the tribe Cephaliini by the combination of the high clypeus, strongly widened palp, setulose vein R1, and ejaculator with short sperm pump and long fan-like apodeme. It clearly differs from other members of the tribe by the combination of elongate, narrow, apically truncated flagellomere 1, robust, mainly shining thorax with pair of microtrichose vittae, well developed proepisternal, postpronotal, acrostichal, 2 pairs of dorsocentral and scutellar setae, wing with entirely setulose vein R1 abdominal tergites devoid of microtrichia, sternites and abdominal pleura narrow, male genitalia with short epandrium, numerous (7–8) prensisetae arranged into a row along posterior margin, shallow hypandrium with pair of setulose pregonites, no postgonites or epiphallus, and an almost bare phallus with a pair of long spines submedially.
