New combinations and synonymies for Neotropical species of Diaphorinae (Diptera: Dolichopodidae).

Anhand von Untersuchungen an Material von Dolichopodidae (Diptera) der Senckenberg Naturhistorischen Sammlung in Dresden werden acht neotropische Arten der Gattung Diaphorus Meigen in die Gattung Chrysotus Meigen übertragen: C. amicus (Parent), comb. n.; C. ciliatus (Becker), comb. n. (= C. superbiens (Parent), comb. n. et syn. n.); C. hamatus (Parent), comb. n.; C. vicinus (Becker), comb. n., nec Parent; C. luteipalpus (Parent), comb. n.; C. mediotinctus (Becker), comb. n.; C. propinquus (Becker), comb. n. Zusätzlich wird C. kallweiti Capellari & Amorim, nom. n. als Ersatzname für C. vicinus Parent, nec C. vicinus (Becker), comb. n. vorgeschlagen. C. diligens Parent ist ein Junior-Synonym von C. viridis Becker. Für Arten, die Syntypen in ihren Typenserien enthalten, werden Lectotyp und Paralectotypen festgelegt. Die mediotinctus-Gruppe, darunter fünf südamerikanische Arten, wird als kleiner Zweig innerhalb von Chrysotus angesehen. Ein Bestimmungsschlüssel zu diesen Arten ist vorhanden.StichwörterDiaphorus, Chrysotus, Dubius, Staatliches Museum für Tierkunde DresdenNomenklatorische Handlungenamicus (Parent, 1931) (Chrysotus), comb. n. hitherto Diaphorus amicus Parent, 1931ciliatus (Becker, 1922) (Chrysotus), comb. n. hitherto Diaphorus ciliatus Becker, 1922diligens Parent, 1931 (Chrysotus), LT; syn. n. of Chrysotus viridis Becker, 1922hamatus (Parent, 1931) (Chrysotus), comb. n. hitherto Diaphorus hamatus Parent, 1931luteipalpus (Parent, 1929) (Chrysotus), comb. n. hitherto Diaphorus luteipalpus Parent, 1929mediotinctus (Becker, 1922) (Chrysotus), LT; comb. n. hitherto Diaphorus mediotinctus Becker, 1922propinquus (Becker, 1922) (Chrysotus), LT; comb. n. hitherto Diaphorus propinquus Becker, 1922vicinus (Becker, 1922) (Chrysotus), LT; comb. n. hitherto Diaphorus propinquus Becker, 1922superbiens Parent, 1931 (Diaphorus), syn. n. of Chrysotus ciliatus (Becker, 1922)Based on examination of the Dolichopodidae (Diptera) material in the Senckenberg Naturhistorische Sammlung Dresden, eight Neotropical species of Diaphorus Meigen are herein transferred to the genus Chrysotus Meigen: C. amicus (Parent), comb. n.; C. ciliatus (Becker), comb. n.

Additionally, C. kallweiti Capellari & Amorim, nom. n. is proposed as a replacement name for C. vicinus Parent, nec C. vicinus (Becker), comb. n., and C. diligens Parent is found to be a junior-synonym of C. viridis Becker. Lectotype and paralectotypes are designated for species with syntypes in their type-series. The mediotinctus-group is proposed within Chrysotus for a small clade including five South American species, and an identification key to the species of the group is provided.KeywordsDiaphorus, Chrysotus, Dubius, Staatliches Museum für Tierkunde DresdenNomenclatural Actsamicus (Parent, 1931) (Chrysotus), comb. n. hitherto Diaphorus amicus Parent, 1931ciliatus (Becker, 1922) (Chrysotus), comb. n. hitherto Diaphorus ciliatus Becker, 1922diligens Parent, 1931 (Chrysotus), LT; syn. n. of Chrysotus viridis Becker, 1922hamatus (Parent, 1931) (Chrysotus), comb. n. hitherto Diaphorus hamatus Parent, 1931luteipalpus (Parent, 1929) (Chrysotus), comb. n. hitherto Diaphorus luteipalpus Parent, 1929mediotinctus (Becker, 1922) (Chrysotus), LT; comb. n. hitherto Diaphorus mediotinctus Becker, 1922propinquus (Becker, 1922) (Chrysotus), LT; comb. n. hitherto Diaphorus propinquus Becker, 1922vicinus (Becker, 1922) (Chrysotus), LT; comb. n. hitherto Diaphorus propinquus Becker, 1922superbiens Parent, 1931 (Diaphorus), syn. n. of Chrysotus ciliatus (Becker, 1922

Checklist of the dipterofauna (Insecta) from Roraima, Brazil, with special reference to the Brazilian Ecological Station of Maracá

Roraima is a Brazilian state located in the northern portion of the Amazon basin, with few studies regarding its biodiversity. The Ecological Station of Maracá (Brazil, state of Roraima) harbors the third largest Brazilian pluvial island and is composed of a transitional landscape of savanna and Amazon rainforest components. Despite its ecological importance and strategic localization, few studies covered the dipterofauna of this locality. An updated checklist addressing 41 families of true flies (Diptera) occurring in Roraima is presented based on the literature and the specimens collected during a field expedition that occurred in 2015. This checklist brings several improvements such as new records of 165 taxa to the state of Roraima, 29 taxa to Brazil, and 259 morphotypes, mostly likely representing undescribed species

Two new species of Neurigona Rondani from northern and northeastern Brazil (Diptera, Dolichopodidae)

Two new species of Neurigona Rondani from northern and northeastern Brazil (Diptera, Dolichopodidae). Two new species of Neurigona Rondani (Diptera: Dolichopodidae) of the brevitibia-group are described from northern and northeastern Brazil: N. lenae sp. nov. and N. manauara sp. nov. A key to males of the brevitibia-group is provided
