Generic diagnosis. In order to avoid repetition in the species descriptions, we here present those features found in all the known Nephochaetopteryx species (males and females).

Head. Gena and postgena with black setulae. Parafacial plate with very short, fine setae along lower anterior eye margin. One or two proclinate fronto-orbital setae (also in males). Two orbital setae. Inner vertical setae parallel and outer vertical setae divergent, differentiated from post-oculars. Occiput with black setulae. Scape and pedicel brown, first flagellomere gray, arista plumose in basal half.

Thorax. Brown with gold-gray microtomentum; scutum with three black longitudinal stripes; scutellum with a median black spot on anterior margin. Chaetotaxy: acrostichals = 0+1 (fine); postpronotals = 3; notopleurals = 2 with 1 to 2 subprimary notopleurals; postalars = 2; proepisternals = 2; proepimerals = 1; katepisternals = 3. Postallar wall and metasternum setulose. Scutellum with 1 pair of basal setae, 1 pair of lateral setae, 1 pair of apical setae and no discal setae. Legs. Brown. Fore femur with rows of anterodorsal and anteroventral setae. Fore tibia with one anteroventral seta in distal half and two posterodorsal setae in proximal half. Mid femur with two or three setae on anterior surface, rows of anteroventral and posteroventral setae on proximal half, and two apical setae on posterior surface. Mid femur of male with a ctenidium of rounded spines (circular cross section) on posteroventral surface. Mid tibia with two posterodorsal setae on distal half. Hind coxa with stout setae on posterior surface. Hind femur with two apical setae on posterior surface and rows of anterodorsal and anteroventral setae, first anteroventral seta about two times the length of the other setae. Hind tibia with two anterodorsal and two posterodorsal setae. Apical setae present on all tibiae. Wing. Vein R 1 entirely setulose dorsally. Third costal section bare on ventral surface. Wing hyaline or fumose between apical part of vein R 2+3 and costal vein. Cell r 4+5 open. Tegula blackish. Basicosta white.

Male terminalia. Sternite 5 usually with an arm, a lobe, and a cleft. Syntergosternite 7+8 and epandrium red or black. Basiphallus and distiphallus connected by a desclerotized strip. Acrophallus composed of capitis, hillae, lateral styli and median stylus. Lateral and median styli tubular.

Recognition. Nephochaetopteryx is usually characterized by wing with an apical spot and vein R 1 entirely setulose dorsally ( Pape 1996). However, some specimens belonging to this genus have a hyaline wing, and some species of Panava Dodge and Sarcofahrtiopsis Hall also show R 1 entirely setulose ( Lopes 1978; Carvalho-Filho et al. 2014). According to the phylogenetic hypothesis of Buenaventura & Pape (2018), Nephochaetopteryx is a natural group of species with three possible autapomorphies: “hind coxa with thick setae posteriorly”, “mid tibia with neither antero-dorsal nor antero-ventral setae” and “wing fumose between apical part of veins R 2+3 and C”.

Another feature found only in species of Nephochaetopteryx is the “inner process of vesica” covered with minute spine-like cuticular projections. However, the “inner process of vesica” is reduced or absent in N. angustifrons and N. pallidifacies . The term “inner process of vesica” is utilized to denominate the structure that Lopes called “base of ventralia” in the description of the male terminalia of his new species Nephochaetopteryx pacatubensis Lopes, 1975a . This term was also utilized by Lopes (1975a) to designate the structure covered with spine-like projections and located inside the distiphallus, attached to the basal portion of the vesica. In the same work, Lopes named a similar structure located inside the distiphallus of N. pallidiventris as “protection of glans”. However, as these structures are located inside the distiphallus and are covered with spine-like projections, we assume that they are homologous. This structure was labeled as “vesical arm-shaped lever” by Buenaventura & Pape (2018, fig. 18B), and according to them it is composed of an “apex” and a “base”. The “apex” is the visible portion of the “vesical arm-shaped lever” body that is joined with the “distal section of vesica”. The base is the portion of the “vesical arm-shaped lever” body that is usually hidden within the paraphallic tube. Based on the figure provided by Bue- naventura & Pape (2018, fig. 18B), it is possible to assesses that the basal portion of the “vesical arm-shaped lever” is the “inner process of vesica”. These authors also mentioned that in Nephochaetopteryx , the “vesical arm-shaped lever” apex is rounded or bilobed. Nephochaetopteryx is a speciose genus with more than 35 described species, but Buenaventura & Pape (2018) analyzed few species (about three). The vesica in Nephochaetopteryx is highly variable in shape and none of them seems to have a rounded or bilobed “vesical arm-shaped lever”. In addition, it is very difficult to assesse the limits between the “vesical arm-shaped lever” and the “distal section of vesica” in most of the species of this genus. For these reasons, we did not utilize the term “vesical arm-shaped lever” and we are utilizing the term “inner process of vesica” to denominate the basal portion of the “vesical arm-shaped lever” sensu Buenaventura & Pape (2018).

Buenaventura & Pape (2018) provided a list of diagnostic features for the genus Nephochaetopteryx , but some of them are not present in all species, such as “male abdominal ST4 [= sternite 4] with a dense patch of erect black setae near posterior margin”, a feature present only in few species. They also mentioned “vesica with distal section ornamented”, but the term “ornamented” was not explained. Based on the SEM images of the male terminalia of Nephochaetopteryx species showed by Buenaventura & Pape (2018, figs 18A–C, 25E), it is not possible to assesses what exactly the ornamentation is.

Species of Nephochaetopteryx are easily recognized by the following combination of features: small to medium-sized flies (4.0– 7.3 mm in length); wing vein R 1 entirely setulose dorsally; wing fumose between apical part of vein R 2+3 and costal vein or more rarely hyaline; male with one or two proclinate orbital setae; notopleuron with subprimary setae; postalar wall setulose; metasternum setulose; male mid femur with a ctenidium; hind coxa with stout setae on posterior surface; male sternite 5 usually with an arm, a lobe and a cleft; basiphallus and distiphallus connected by a desclerotized strip.

Biology. Little is known about the biology of Nephochaetopteryx species, but according to Lopes (1973), many species, in nature, deposit their larvae in feces of mammals and birds. Lopes (1973) obtained many species of this genus in traps baited with human feces in Brazil and one of us (FSCF) collected an adult male on dog feces in a secondary forest in the Brazilian Amazon. Curran & Walley (1934) also collected specimens of Nephochaetopteryx on human feces in Guyana. Lopes (1936, 1973) reared larvae of various species in an artificial medium composed of “gelose plus horse blood serum” or “gelose plus egg albumine”. Pape & Dahlem (2010) reported on larvae bred from vertebrate carcasses, and N. cyaneiventris , N. orbitalis , and N. pallidiventris have been collected from pig carcasses in Brazil ( Vairo et al. 2011; Mello-Patiu et al. 2014). Females of Nephochaetopteryx have been collected in traps baited with rotting bovine lung in the Brazilian Amazon ( Sousa et al. 2011). However, the natural feeding substrate of the larvae has not yet been reported.

Lopes (1975a) collected many adult Nephochaetopteryx flies in Van Someren-Rydon traps (butterfly trap) bait- ed with rotting banana in Ceará (northern Brazil). Van Someren-Rydon traps baited with pineapple were useful for collecting male specimens in a secondary forest in the Brazilian Amazon (FSCF, personal observation). Pape & Dahlem (2010) mentioned that fermented fruits are useful for attracting specimens of Nephochaetopteryx .

Nephochaetopteryx distincta Dodge, 1968b was collected flying close to trails of army ants of the species Eciton burchelli Westwood ( Hymenoptera : Formicidae ) (information from specimen label). Adults of N. limpidipennis Lopes, 1976 were collected on mango flowers ( Mangifera indica ; Anacardiaceae ) in Mexico (information from specimen label).
