First record of egg sac predation of the fly Pseudogaurax cingulatus Sabrosky (Diptera, Chloropidae) upon spider Tetragnatha sp. (Araneae, Tetragnathidae) in northern Brazil

Pseudogaurax Malloch is a worldwide genus of Chloropidae with 33 species in the Neotropical region and 12 occurring in Brazil. The genus is well-known for the feeding habits of its larvae which attack egg masses and larvae of several arthropods, usually breeding in the egg sacs of spiders. In this study, we expanded the distribution of P. cingulatus to northern Brazil and recorded for the first time the species preying on Tetragnatha egg sacs. In addition, diagnosis, digital images and a distribution map are provided

On the identity of Lepidodexia (Orosarcophaga) ornata (Townsend, 1927) (Diptera: Sarcophagidae) and a new generic synonym

The revision of the sarcophagid species Lepidodexia (Orosarcophaga) ornata (Townsend, 1927) reveals its identity and a generic synonym. The male terminalia of this species was studied in detail for the first time and revealed its congeneric affinities with Oxyvinia Dodge, 1966. Consequently, the generic status of Orosarcophaga Townsend, 1927 was revalidated, including Oxyvinia Dodge, 1966 as its junior synonym, and O. ornata was corroborated as a valid species and name. Moreover, we provide an updated generic diagnosis of Orosarcophaga, a list of the eleven species of the genus with their distribution, and a detailed diagnosis of O. ornata

New species of Inbiomyia from the Atlantic Forest.

17 pages : illustrations (some color), color maps ; 26 cm.We describe and illustrate Inbiomyia azevedoi, sp. nov., the first species of Inbiomyiidae known from the Atlantic Forest in southeastern Brazil. SEM photos show that the bifurcated labella have on their ventral face rows of scalelike rasping teeth that may be used to graze on green algae, as the gut content of some specimens suggest. A reanalysis of the phylogeny of the genus using Australimyza mcalpineorum as designated outgroup and including I. azevedoi shows that all four groups of species previously proposed for the genus are monophyletic if I. anodonta is removed from the scoliostylus group. Inbiomyia anodonta and I. azevedoi are here transferred to the anemosyris group. In our results with implied weight, I. exul is sister to a clade including all other species of the genus, while the scoliostylus group appears as sister to the clade (mcalpineourum group + anemosyris group)

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

Revision of Camarota Meigen (Diptera: Chloropidae), with a new species from Uganda

Riccardi PR, von Tschirnhaus M. Revision of Camarota Meigen (Diptera: Chloropidae), with a new species from Uganda. ZOOTAXA. 2018;4526(2):221-231.The genus Camarota is revised with the description of a new species-C. ugandae-and a key to species. The genus Paracamarota Cherian is considered here as a new junior synonym of Camarota. Distinctive morphological characters, such as the dark transverse band on the arista, the "vena spuria" of the wing and the placement of apical scutellar bristles, are interpreted

Coroichlorops yungas Sabrosky & Paganelli

Coroichlorops yungas (Sabrosky & Paganelli), 1984 (Figs. 1–4) Coroichlorops yungas (Sabrosky & Paganelli), 1984: 35 (Chlorops; nom. nov. for maculata Duda, 1930). (Paganelli 2002: 37, figs. 100–106). Type-locality: Bolivia, Coroico. Holotype ♂ with label: (1) printed with handwritten inscriptions on green paper: “ Bolivia | 30.xi.06 | Yungas von Coroico | 1800m ” [SNSD]. Refs.: Sabrosky & Paganelli 1984; Paganelli 2002. maculata Duda, 1930: 124 (Chlorops; preocc. Walker, 1849). maculosa Duda, 1931: 171 (Chlorops; error for maculata Duda, 1930, preocc. Loew, 1872). Comments. The holotype of C. yungas is well preserved, with no missing parts. Externally C. yungas is very similar to C. plaumanni. Nevertheless, C. yungas presents a wide shallow sulcus in the ocellar triangle, a long sensorial pit on the first flagellomere, a complete facial carina, and almost indistinct scutum stripes. No additional specimens of C. yungas have been found in the collections studied.Published as part of Riccardi, Paula Raile & Amorim, Dalton De Souza, 2016, Revision of the Neotropical genus Coroichlorops Paganelli 2002 (Diptera: Chloropidae), pp. 435-443 in Zootaxa 4093 (3) on page 436, DOI: 10.11646/zootaxa.4093.3.9, http://zenodo.org/record/26263

Cercus short, yellow.</p> <p> <b>Etymology.</b> The specific epithet of the species name comes from the Latin word <i>antenna</i>, as a reference to the wide arista.</p> <p> <b>Comments</b>. The lateral margins of the ocellar triangle are relatively straight, diverging from the drop-shape condition seen in the other species of <i>Coroichlorops</i>. The most aberrant characteristic of <i>C. antennatus</i>, however, is the flat wide arista. A long sensorial pit on the first flagellomere is a feature shared between <i>C. antennatus</i> and <i>C. yungas</i>. The arista of the holotype of <i>C. antennatus</i> is broken and only with the most basal aristomere present, so the description of the arista was based on the paratype.</p>Published as part of <i>Riccardi, Paula Raile & Amorim, Dalton De Souza, 2016, Revision of the Neotropical genus Coroichlorops Paganelli 2002 (Diptera: Chloropidae), pp. 435-443 in Zootaxa 4093 (3)</i> on pages 439-441, DOI: 10.11646/zootaxa.4093.3.9, <a href="http://zenodo.org/record/262631">http://zenodo.org/record/262631</a&gt
