This study is part of an ongoing series of studies on the Vietnamese cyclorrhaphous fauna. One new species from Vietnam, Nothybus kuznetsovorum sp.nov., is described and figured. A key to species of Nothybus is provided. Genital structures are described and figured.

One new species of Triphleba Rondani and eight new species of Megaselia Rondani are described from Montseny Natural Park (mainland Spain). The new species are Megaselia arbuciensis García-Romera sp.nov., Megaselia barrientosi García-Romera sp. nov., Megaselia callunae García-Romera sp. nov., Megaselia carminis García-Romera sp. nov., Megaselia ivanis García-Romera sp. nov., Megaselia longianali...

The New World species of Coproica Rondani, 1861 (Diptera: Sphaeroceridae) are reviewed on the basis of over 17,000 examined specimens. The genus is divided into three major clades: the C. acutangula, C. vagans, and C. urbana species groups. Eight new species (C. bifurcata, C. bispatha, C. brachystyla, C. diabolica, C. emarginata, C. galapagosensis, C. novacula, and C. testudinea) are described,...

The monotypic genera Epiplagiops Blanchard, 1943 and Tetragrapha Brauer and Bergenstamm, 1891 are revised. Both are invalidated and synonymized with Chetogena Rondani, 1856. Their type-species, Epiplagiops littoralis Blanchard, 1943 and Tetragrapha tessellata Brauer and Bergenstamm, 1891, are studied, redescribed, illustrated, and transferred to Chetogena. A lectotype is designated for T. tesse...

BACKGROUND We describe five new species in the genus Vibrissina Rondani from Area de Conservación Guanacaste (ACG). All species were reared from wild-caught sawfly larvae (Hymenoptera: Symphyta: Argidae and Tenthredinidae). We provide a morphological description of each species together with information on life history, molecular data, and photographic documentation. NEW INFORMATION Five new ...

A new species of Drymeia Meigen, D. pyrenaea sp. nov. is described and distinguished from the very similar D. brumalis (Rondani) based on material from northern Spain and Portugal. It is argued that records of D. brumalis and possibly even D. alpicola (Rondani) from outside Europe are probably based on misidentifications. A previously unnoticed, unique prestomal teeth structure is reported from...

The first checklist of the Tephritidae of Morocco, containing 59 species, is presented here. Out of 38 species collected during the present project, three (Campiglossa martii (Becker, 1908), Tephritis divisa (Rondani, 1871), and Terellia sp. near longicauda) present new records for North Africa, and ten (Carpomya incompleta (Becker, 1903), Chaetorellia conjuncta (Becker, 1913), Chetostoma curvi...

The Caribbean and North American species of the large, otherwise neotropical genus Grallipeza Rondani (Diptera: Micropezidae: Taeniapterinae) are revised and keyed. One species, G. nebulosa (Loew), is endemic to the southeastern United States and eighteen species are endemic to single Caribbean islands. Of these, the following nine are described as new: Grallipeza abeja, G. albiterga, G. cliffi...
