Maruina Müller, 1895 (Diptera: Psychodidae): description of four new species from Brazil, with revised diagnoses for the genus and subgenera.

Maruina is an aquatic genus of Psychodidae with larvae and pupae adapted for life in flowing water. The genus is restricted to the Western Hemisphere, with the majority of species distributed in the Neotropical region. 39 Maruina species are described, with 11 currently known to occur in Brazil, all recorded from the eastern Biomes of Atlantic forest and Caatinga. Here we describe four new Maruina species collected from Brazil: Maruina (Aculcina) roraimensis sp. nov., Maruina (Maruina) kallyntrona sp. nov. and M. (M.) mystax sp. nov. constitute the first report of Maruina from Amazonia and M. (A.) pila sp. nov. from the southern portion of the Atlantic forest expands the distribution of the genus to Rio Grande do Sul, the southernmost state of Brazil. Type specimens of some described species were also studied. Redescriptions are completed for M. (M.) garota and M. (M.) namorada, and additional characters and figures are presented for M. (A.) duckhousei, M. (M.) barrettoi and M. (M.) jezeki. M. pilosella and M. spinosa are considered nomina dubia. Diagnostic characters for the genus and both subgenera are revised and distribution maps for Maruina species recorded in Brazil are provided.

New species and records of the Pericoma trifasciata group from Croatia (Diptera: Psychodidae).

Pericoma miljenkoi sp. nov. is described based on adult males from the Plitvicka jezera National Park, Croatia. Pericoma trifasciata is recorded from Croatia for the first time, and COI DNA barcodes are given from specimens collected in Germany. An emended key to adult Pericoma of the trifasciata group is presented. The Croatian Psychodidae fauna now stands at 35 species.

A new species of Sycorax Curtis, 1839 from Atlantic Forest in southeastern Brazil

A new species of Sycorax Curtis, 1839 (Diptera, Psychodidae) from the Atlantic Forest in southeastern Brazil. Sycorax bravoi Santos, Ferreira & Falqueto sp. nov. is described and illustrated based on samples collected with a Möricke trap installed on the ground at the Biological Station of Santa Lúcia, municipality of Santa Teresa, in the Brazilian state of Espírito Santo. Males have a paramere with a spiniform prolongation on the distal surface and an aedeagus with a long posterior membranous dorsal prolongation. Females have a racket-shaped genital furca and tubular spermatheca, tapered on the apical third. This finding raises the number of Sycorax species known from Brazil to seven.

Espécie nova de Sycorax Curtis, 1839 (Diptera, Psychodidae) da Mata Atlântica, sudeste do Brasil. Sycorax bravoi Santos, Ferreira & Falqueto sp. nov. é descrita e ilustrada a partir de exemplares coletados com armadilha Möricke instalada sobre o solo, na Estação Biológica de Santa Lúcia, município de Santa Teresa, estado do Espírito Santo, Brasil. Machos apresentam parâmero com prolongamento espiniforme na superfície distal e edeago com longo prolongamento posterior membranoso e dorsal. Fêmeas com forquilha genital em forma de raquete e espermateca tubular, afilada no terço apical. Eleva-se para sete o número de espécies de Sycorax para o Brasil.
