A revision of the shore-fly genus Philotelma Becker (Diptera: Ephydridae)

Abstract

All known shore-fly species (5) of the genus Philotelma Becker are revised, including P. tecopa, new species (California. Inyo: Tecopa Hot Spring (36°52.7'N, 116°13.9'W)). Philotelma is only known from the Northern Hemisphere, and the included species are generally more widespread than previously known. With discovery that some species are more widespread and correction of the identification of others, the following new synonymies are proposed: P. alaskense Cresson = P. defectum (Haliday) and P. strandi Duda and P. tamarani Zatwarnicki & Báez = P. parvum (Kramer). The Afrotropical species, Philotelma mirabilis Canzoneri & Meneghini, is transferred to the genus Lamproscatella Hendel (new combination). A lectotype is designated for Ephydra defecta Haliday. For perspective and to facilitate identification, a key to the genera of Scatellini is provided. All species are illustrated and distribution maps are also provided.

Some Diptera records of National Nature Reserves Dreveník and Sivá Brada (Slovakia)

“…Note: Species known from Austria, Britain I., Czech Republic, Denmark, East Palaearctic, Estonia, Finland, Germany, Ireland, Latvia, Lithuania, Nearctic region, Norway, Poland, Sweden, the Netherlands(Bystrowski 2011). First record for Slovakia(Kubátová-Hiršová 2009).Psilopa stackelbergi Nartshuk, 1970Material examined: site 2, 1 ♂. Note: Second record for Slovakia, known only from Háj village env (Zatwarnicki 2018)…”

Heterogeneity in shore flies – the case ofGlenantheHaliday (Diptera: Ephydridae) in the Old World

“…Th e principal source of characters (synapomorphies) to document these phylogenetic associations is structures of the male terminalia. Th e latter studies, especially Zatwarnicki (1992), indicate that the tribe Lipochaetini is closely related to the tribe Hecamedini and includes four genera (date and author(s) who fi rst placed the genus in Lipochaetini are noted in parenthesis): Glenanthe (Mathis & Zatwarnicki 1990b), Paraglenanthe (Zatwarnicki 1992), Lipochaeta (Becker 1896), and Homalometopus (Mathis 1984). Recent revisionary and phylogenetic studies of genera of the tribe are Mathis (1995) on New World Glenanthe, Mathis (1984) and Munari (1988) on Homalometopus, Mathis & Trautwein (2003) on Lipochaeta, and Mathis & Zatwarnicki (2004) on Tronamyia.…”
