Abstract

ABSTRACT: Smicridea McLachlan comprises 253 species divided into two subgenera: Smicridea and Rhyacophylax Müller. Smicridea ( Smicridea ) comprises species with males possessing two pairs of internal glands in abdominal segments VI and VII and hind legs bearing two pairs of spurs. Among species of this subgenus, those assigned to the Smicridea ( Smicridea ) fasciatella species group are characterized by a simple tubular phallus, presenting an apex with eversible sclerites. The aim of this paper is to describe and illustrate two new species in the S . ( Smicridea ) fasciatella species group and the female of Smicridea ( Smicridea ) capao Vilarino, Dias & Calor, 2019. Fieldwork was carried out in mountain ranges located in Bahia State, northeastern Brazil, both in the Atlantic Forest biome (Serra Bonita Reserve) and in the Caatinga biome (Chapada Diamantina Complex, Parque Municipal de Mucugê). Smicridea ( Smicridea ) kamakan sp. nov. and Smicridea ( Smicridea ) serrati sp. nov. can be recognized mainly by the morphology of tergum X and the inferior appendages. In addition, two couples of S . ( Smicridea ) capao were collected and resulted in the direct association of males and females; the female has a very conspicuous, oval sclerite VIII, with the apex constricted in the anterior portion, in ventral view. urn:lsid:zoobank.org:pub:CF8BAE97-7D6B-4460-8A9D-35BBBACF2BE0
