Phylogenetic analysis of the sharpshooter genus Subrasaca Young, 1977 (Hemiptera,Cicadellidae, Cicadellini)

The South American sharpshooter genus Subrasaca comprises 14 species. Some species of this genus are quite common in the Brazilian Atlantic Rainforest. In this paper, a phylogenetic analysis of Subrasaca, based on a matrix of 20 terminal taxa and 72 morphological characters of the head, thorax, and male and female genitalia, is presented. The analysis yielded six equally most parsimonious trees (197 steps, CI = 0.6091, RI = 0.5722, and RC = 0.3486). The results suggest that Subrasaca is a monophyletic taxon, although the genus branch is not robust. The clade showing the highest bootstrap and Bremer scores is formed by species with longitudinal dark brown to black stripes on the forewings (Subrasaca bimaculata, Subrasaca constricta, Subrasaca curvovittata, and Subrasaca flavolineata), followed by Subrasaca atronasa + Subrasaca austera.

A remarkable new genus and a new species of chewing louse (Phthiraptera,Ischnocera, Philopteridae) from Brazil

A new genus of chewing louse as Bobdalgleishia, and its type species Bobdalgleishia stephanophallus sp. n. (Phthiraptera) belonging to the Brueelia-complex (Ischnocera: Philopteridae) are described. Adults of the new species are fully described, illustrated and compared morphologically with the type species of Motmotnirmus Mey & Barker, 2014, which is its closest relative.

Bobdalgleishia is a remarkable genus with unique morphological and chaetotaxic characters which readily separate it from other members of the Brueelia-complex, in particular by having the first two marginal temporal and ocular setae very long.

Three new species of the genus Ripipteryx from Colombia (Orthoptera,Ripipterygidae)

Three new species of Ripipteryx Newman (Orthoptera: Tridactyloidea: Ripipterygidae) are described from Colombia; namely Ripipteryx diegoi sp. n. (Forceps Group) and Ripipteryx guacharoensis sp. n. (Marginipennis Group) from Parque Nacional Natural Cueva de los Guacharos in Huila, and Ripipteryx gorgonaensis sp. n. (Crassicornis Group) from Parque Nacional Natural Gorgona in Cauca. Ripipteryx diegoi sp. n. is characterized by the antennae black with white spots on flagellomeres 3–7, male subgenital plate with median ridge forming a bilobed setose process, epiproct produced laterally near its base and phallic complex with virga thickened distally and not reaching beyond the membrane. Ripipteryx guacharoensis sp. n. is characterized by the antennae thick with white spots present dorsally on flagellomeres 1–4 and 8, epiproct narrow and triangular, uncus reduced and lacking a distal hook, phallic complex with a concave ventral plate and a dorsal elevation in the middle extended to the virga, and the virga itself with two small projections basally. Ripipteryx gorgonaensis sp. n. is characterized by the epiproct with a lateral notch, antennae with a white dorsal spot on flagellomere 1 and flagellomeres 4–7 entirely white. The antennal color pattern of Ripipteryx gorgonaensis sp. n. strongly resembles that of Ripipteryx atra but differs from the latter in the absence of any significant morphological modification of the flagellomeres.
