Abstract
A new species of moth fly, Maruina cunhanta Araújo & Santos, sp. nov., is described from the state of Espírito Santo, southeast Brazil. A checklist of Maruina is also provided
Highlights
The species of Maruina are separated in two subgenera, Maruina (Maruina) and Maruina (Alcucina) with 27 and 16 species, respectively
Forty-three species of Maruina Müller, 1895 occur in the Americas, four in the Nearctic region, from United States and 39 in the Neotropical Region, with 15 species recorded from Brazil (Kincaid 1899; Johannsen 1938; Vaillant 1963, 1989; Hogue 1973; Wagner 1988; Hogue 1990; Wagner and Joost 1994; Ibáñez-Bernal 1994; Müller 1895; Bravo e Lago 2003; Bravo 2004, 2005; Bravo and Araújo 2018; Camico et al 2019)
These subgenera are differentiated by the following combination of characters: species of Maruina (A) have monomorphic aedeagal spines, males lack the nine sternite, the eye bridge is contiguous or separated by four even ocular facet diameters, and R3 is united to R2
Summary
The species of Maruina are separated in two subgenera, Maruina (Maruina) and Maruina (Alcucina) with 27 and 16 species, respectively. The species of the genus are recognized by the lanceolate form of the wing, four times as long as wide (Hogue 1973). These subgenera are differentiated by the following combination of characters: species of Maruina (A) have monomorphic aedeagal spines, males lack the nine sternite, the eye bridge is contiguous or separated by four even ocular facet diameters, and R3 is united to R2. The species of Maruina (M.), on the other hand, have di- or trimorphic aedeagal spines, the ninth sternite of male is well-developed, the eye bridge is separated by 7 to 10 facet diameters, and R3 is not united to R2 (Hogue 1973; Bravo 2004). MATERIAL AND METHODS The specimen studied was collected at Reserva Biológica de Duas Bocas, at area of Atlantic rainforest in the state of Espírito Santo, Brazil, using a CDC light trap. RESULTS Maruina (Aculcina) cunhanta Araújo & Santos, sp. Hogue (1973) traditionally employed Latin-American regional expressions that were used in reference to women to name new species of Maruina. The new species is mainly characterized by the presence of contiguous eye bridge, monomorphic aedeagal spines, short and wide palpal segments approximately of the same length.
