Taxonomia da subfamília Corinninae (Araneae, Corinnidae) nas regiões neotropical e neártica

The subfamily Corinninae is characterized and diagnosed. Two synapomorphies are hypothesized for the subfamily, both regarding the male palpal reservoir, which is primarily coiled and presents a sclerotized distal sector. Seventeen genera are recognized, six of which are new: Abapeba (type species Corinna lacertosa Simon), Erendira (type species Corinna pallidoguttata Simon), Septentrinna (type species Corinna bicalcarata Simon), Simonestus (type species Diestus validus Simon), Tapixaua (type species T. callida sp. nov.) and Tupirinna (type species T. rosae sp. nov.). The genera Creugas Thorell, Falconina Brignoli and Paradiestus Mello-Leitão are revalidated. Diestus Simon and Lausus Simon are newly synonymized with Corinna C. L. Koch. Chemmis Simon is included in the synonymy of Megalostrata Karsch. Hypsinotus L. Koch is removed from the synonymy of Corinna and included in the synonymy of Creugas.

Revisão taxonômica do gênero Homodiaetus (Teleostei, Siluriformes, Trichomycteridae)

Its distribution is restricted to southeastern South America, from Uruguay to Paraguay river at west to the coastal drainages of Rio de Janeiro State, Brazil. Homodiaetus is currently distinguished from other genus of Stegophilinae by the combination of the following characters: origin of ventral-fin at midlength between the snout tip and the caudal-fin origin; opercle with three or more odontodes; and gill membranes confluent with the istmus. Homodiaetus anisitsi Eigenmann & Ward, 1907, is diagnosed by the caudal-fin with black middle rays, margin of upper and lower procurrent caudal-fin rays with dark stripes extending to the caudal-fin, and 3-6 opercular odontodes; H. passarellii (Ribeiro, 1944) with 6-7 opercular odontodes, 21-24 lower procurrent caudal-fin rays and 23-26 upper procurrent caudal-fin rays; H. banguela sp. nov. with 9 opercular odontodes, 17-19 lower procurrent caudal-fin rays, 17-22 upper procurrent caudal-fin rays, reduction of fourth pharyngobranchial with only three teeth and untoothed fifth ceratobranchial; and H. graciosa sp. nov. with 5-6 dentary rows, 7-9 opercular odontodes and 16-23 upper procurrent caudal-fin rays.
