A revision of the genera and species of the Neotropical family Mesembrinellidae (Diptera: Oestroidea)

Abstract

The Neotropical family Mesembrinellidae is revised. A total of 53 valid, extant species are included in the family, including 15 described as new and 38 redescribed based on study of type and non-type material and of the literature. A total of 18 primary types were examined. An additional ca. 2300 specimens, belonging to 47 species, were studied in detail, including dissection and photographic documentation of terminalia, with many females illustrated for the first time. Keys to subfamilies, genera, species-groups and species are provided. Type specimens of six species housed in South American institutions could not be obtained for study, i.e., M. bequaerti Séguy, 1925 and the five recently described species M. andina (Wolff et al., 2014), M. carvalhoi (Wolff et al., 2013b), M. cordillera (Wolff & Ramos-Pastrana in Wolff et al., 2017), M. obscura (Wolff in Wolff et al., 2017) and Laneella patriciae (Wolff, 2013). We accept the synonymy, proposed by previous authors, of Eumesembrinella Townsend, 1931 with Mesembrinella Giglio-Tos, 1893. In addition, we synonymize the genera Albuquerquea Mello, 1967, Giovanella Bonatto in Bonatto & Marinoni, 2005, Henriquella Bonatto in Bonatto & Marinoni, 2005, Huascaromusca Townsend, 1918 and Thompsoniella Guimarães, 1977 with Mesembrinella Giglio-Tos, 1893, synn. nov., retaining three valid genera in the family: Laneella Mello, 1967, Mesembrinella and Souzalopesiella Guimarães, 1977. Laneella nigripes Guimarães, 1977 and Mesembrinella bellardiana Aldrich, 1922 are fixed as the type species of the genera Laneella Mello, 1967 and Mesembrinella Giglio-Tos, 1893, respectively, under Article 70.3 of the ICZN Code. We separate Mesembrinella into the following species-groups: M. latifrons (Mello, 1967), M. spicata Aldrich, 1925, M. bolivar (Bonatto in Bonatto & Marinoni, 2005), M. aeneiventris (Wiedemann, 1830), M. bicolor (Fabricius, 1805), and M. anomala (Guimarães, 1977). The following 15 new species are described: Laneella fusconitida Whitworth, sp. nov. from Costa Rica, Ecuador and Venezuela, Laneella fuscosquamata Whitworth, sp. nov. from Guatemala and Mexico, Laneella purpurea Whitworth, sp. nov. from Costa Rica, Mesembrinella bullata Whitworth, sp. nov. from Bolivia, Mesembrinella chantryi Whitworth, sp. nov. from French Guiana and Brazil, Mesembrinella epandrioaurantia Whitworth, sp. nov. from Venezuela, Mesembrinella guaramacalensis Whitworth, sp. nov. from Venezuela, Mesembrinella longicercus Whitworth, sp. nov. from Bolivia, Mesembrinella mexicana Whitworth, sp. nov. from Mexico, Mesembrinella nigrocoerulea Whitworth, sp. nov. from Costa Rica, Ecuador and Venezuela, Mesembrinella serrata Whitworth, sp. nov. from Peru, Mesembrinella velasquezae Whitworth, sp. nov. from Venezuela, Mesembrinella violacea Whitworth, sp. nov. from Costa Rica, Mesembrinella woodorum Whitworth, sp. nov. from Ecuador, and Mesembrinella zurquiensis Whitworth, sp. nov. from Costa Rica. Mesembrinella abaca Hall, 1948 is proposed as a junior synonym of Mesembrinella socors (Walker, 1861), syn. nov. Lectotypes are designated for Dexia randa Walker, 1849 (now Mesembrinella) and Mesembrinella pictipennis Aldrich, 1922. We analyze the most extensive DNA-barcode dataset for Mesembrinellidae to date, encompassing the three genera considered valid and including 188 sequences (178 new) from 35 species, with data for 23 species provided for the first time. The topology of the resulting Neighbor-Joining tree is mostly congruent with morphology; however, some species show considerable genetic variation that is not reflected by morphology. Finally, we include a corrigendum to the recent Zootaxa paper on Nearctic Calliphora Robineau-Desvoidy (Diptera: Calliphoridae) by Tantawi et al.

Protein‐encoding ultraconserved elements provide a new phylogenomic perspective of Oestroidea flies (Diptera: Calyptratae)

“…(2017) who treated all species as one single genus Mesembrinella . Whitworth & Yusseff‐Vanegas (2019) revised the family and arranged species into genera Laneella , Mesembrinella and Souzalopesiella Guimarães, which was in agreement with Marinho et al . (2017).…”

“…(2017). Our UCE data, although limited in taxon sampling, supports the monophyly of Mesembrinella , which is consistent with other molecular data (Cerretti et al ., 2017; Marinho et al ., 2017) and with the classification proposed by Whitworth & Yusseff‐Vanegas (2019). Mesembrinellidae is limited to Neotropical rainforests (Marinho et al ., 2017) and its possible close phylogenetic relationship to the dung breeders of the Australian Ulurumyiidae (Kutty et al ., 2019); Michelsen & Pape (2017) suggest an interesting potential biogeographic connection through Antarctica.…”

A survey of Calliphoridae and Mesembrinellidae (Diptera) in semideciduous seasonal forest, Paraná, Brazil

“…Subsequently, Moura et al (1997) and Caleffe et al (2015) recorded three species of Calliphoridae each, in studies focusing on forensic entomology. The other species records of this family in Paraná are in taxonomic revisions (WHITWORTH, 2014;MARINHO et al, 2017;WHITWORTH;YUSSEFF-VANEGAS, 2019).…”

“…The collected specimens were fixed in 70% alcohol and taken to the laboratory for screening and identification. The biological material was identified using the taxonomic keys in Kosmann et al (2013), Whitworth (2014) and Whitworth and Yusseff-Vanegas (2019). Reference material was deposited in the didacticscientific collection at the Federal Institute of Paraná (IFPR), campus Umuarama.…”

Evaluación ecológica rápida de moscas necrófagas (Diptera, Calyptratae) en un mosaico paisajístico de los Andes Colombianos

“…In each assessed site, an active manual collection for thirty minutes was performed, using an entomological net, and as a bait, a three-day-old fish head rotten (sampling effort unit). Flies gathered were preserved in ethanol (C2H5OH) 90% and taxonomically identified following the keys of Amat, Vélez, and Wolff (2008); Grella et al (2015) Wolff (2008; Grella et al (2015); Whitworth (2014); Whitworth and Yusseff-Vanegas (2019). Pinned and labeled specimens were deposited at Colección Entomológica Tecnológico de Antioquia, Institución Universitaria (CETdeA) located in Medellín, Colombia, and also in the Colección Entomológica del Instituto Alexander Von Humboldt (IAvH) in Villa de Leiva, Colombia.…”
