Four new species and new records of Thinophilus Wahlberg, 1844 (Diptera: Dolichopodidae) from Iranian mangroves with a key to the species known from Iran

Four new long-legged fly species, Thinophilus albihirtus sp. n., Thinophilus albisetosus sp. n., Thinophilus nigrihirtus sp. n., and Thinophilus qeshmensis sp. n., from southern Iran, all collected in or near the mangrove forests, are described and illustrated. Four more species of the genus are collected from the same localities. Polyzonal T. indigenus Becker, 1902 is found in the Fars Province. Three known species are firstly recorded from Iran (T. deemingi Grichanov, 2023, T. gallagheri Grichanov, 2023 and T. ochripalpis Becker, 1910). The Iranian species are considered members of one Oriental (T. murphy group), two Afrotropical species groups (T. gallagheri and T. calopus groups) and T. indigenus lineage distributed widely in the Old World. A check-list and identification key to males of 12 species known from Iran are provided.ZooBank Article LSID: urn:lsid:zoobank.org:pub:BB31A71D-585E-4E0C-9C06-4022A7444DD

Diversity of the genus Dolichopus Latreille in three different habitats of East Azerbaijan Province, with new records for Iran

Diversitat del gènere Dolichopus Latreille en tres hàbitats diferents de la província d'Azerbaitjan Oriental amb nous registres a l'Iran El present treball és un estudi sobre la diversitat d'espècies del gènere Dolichopus a la província d'Azerbaitjan Oriental (Iran). Aquestes espècies van ser recol·lectades amb una xarxa entomològica estàndard en tres hàbitats (bosc, praderia i zones pantanoses) al nord-oest de l'Iran l'any 2013. Segons les dades recollides, l'àrea boscosa amb índexs de diversitat més elevats (H‘ = 2.53, 14 espècies i H‘ = 2.19, 10 espècies, a les regions de Chichakli i Keleybar, respectivament) és la que presenta una varietat i abundància d'espècies més gran, seguida per les praderies i les zones pantanoses. Les espècies dominants a les àrees estudiades van ser Dolichopus longitarsis i D. simplex. A més a més es van registrar tres espècies (D. siculus, D. kiritshenkoi i D. plumipes) per primera vegada a l'Iran. Els caràcters diagnòstics i la distribució geogràfica de les espècies presents a les àrees estudiades s'acompanyen dels valors corresponents.The present study is a survey of species diversity of the genus Dolichopus in East Azerbaijan province, Iran. The species were collected using a standard entomological net from three habitats –forest, grassland and wetland areas– in north-west Iran in 2013. Based on the data collected, the forest area with the highest diversity indices (H‘ = 2.53, 14 species, and H‘ = 2.19, 10 species, in Chichakli and Keleybar regions respectively) had the most diverse and abundant species, followed by grassland and wetland areas. The dominant species in the study areas were Dolichopus longitarsis and D. simplex. Besides, three species (D. siculus, D. kiritshenkoiand D. plumipes) were recorded from Iran for the first time. Diagnostic characters and geographical distribution of the species occurring in the studied areas with supplementary figures are provided.Diversidad del género Dolichopus Latreille en tres hábitats distintos de la provincia de Azerbaiyán Oriental con nuevos registros en Irán El presente trabajo es un estudio sobre la diversidad de especies del género Dolichopus en la provincia de Azerbaiyán Oriental (Irán). Dichas especies fueron recolectadas utilizando una red entomológica estándar en tres hábitats (bosque, pradera y zonas pantanosas) en el noroeste de Irán en el año 2013. Según los datos recogidos, el área boscosa con mayores índices de diversidad (H‘ = 2.53, 14 especies, y H‘ = 2.19, 10 especies, en las regiones de Chichakli y Keleybar, respectivamente) presenta la mayor variedad y abundancia de especies, seguida por las praderas y las zonas pantanosas. Las especies dominantes en las áreas estudiadas fueron Dolichopus longitarsis y D. simplex. Además se registraron tres especies (D. siculus, D. kiritshenkoi y D. plumipes) por primera vez en Irán. Los caracteres diagnósticos y la distribución geográfica de las especies presentes en las áreas estudiadas se acompañan de los valores correspondientes

New records of Dolichopodidae (Diptera) from Mordovia, Russia

A new material of Dolichopodidae has been recently collected and identified, and includes 72 species (39 species are new for the Republic of Mordovia, 60 species have been found for the first time in the Mordovian Nature Reserve and its environs, and one species is new for the Smolny National Park). In total, 98 species are recorded in this region that apparently makes up 40–50% of actual Dolichopodidae fauna in the Republic of Mordovia. This paper provides also distribution pattern for each collected species. The list of species found in the Mordovian Nature Reserve has increased from 11 to 71

An annotated checklist of Dolichopodidae (Diptera) of Chukotka (Russia) with new records

A checklist of Chukchi species is compiled. The present research gives new records, including 26 species found for the first time in Chukotka, three species recorded for the first time in the Palaeartic Region (Argyra albiventris Loew, 1864, Hydrophorus pilitarsis Malloch, 1919, Rhaphium nigrum (Van Duzee, 1923)) in addition to one species new for Russia (Dolichopus pseudomigrans Ringdahl, 1928). In total, 8 genera and 36 species are listed that apparently makes up less than 50% of actual Dolichopodidae fauna of the Okrug. Now 17 Chukchi dolichopodids (47%) are known in the Nearctic Region
