Abstract
Perilestes eustaquioi sp. nov. (holotype male deposited in ABMM collection) from the state of Bahia (municipality of Una), northeastern Brazil, is described and illustrated based on one male specimen. It differs from the other species of the genus mainly by the larger size of the anteclypeus in relations to the postclypeus. Together with P. fragilis Hagen in Selys, 1862 from the state of Sergipe and P. solutus Williamson & Williamson, 1924 from the state of Ceara, these are the first records of Perilestidae from northeastern Brazil.
Highlights
Perilestidae contains 19 species in two Neotropical genera – Perilestes Hagen in Selys-Longchamps, 1862 and Perissolestes Kennedy, 1941 – distinguished by venational characters (GARRISON et al 2010)
Six unquestioned species of Perilestes occur in Brazil (LENCIONI 2005), as described by SELYS-LONGCHAMPS (1862, 1886), KENNEDY (1941), KIMMINS (1958), and WILLIAMSON & WILLIAMSON (1924)
I describe a new species of Perilestes from the state of Bahia that, together with P. solutus Williamson & Williamson, 1924 from the state of Ceará and P. fragilis Hagen in SelysLongchamps, 1862 from the state of Sergipe, constitute the first record of the Perilestidae from northeastern Brazil
Summary
The material examined consists of 1 male of Perilestes eustaquioi sp. nov. (holotype) collected in municipality of Una, state of Bahia (20-11-1987), Alvarenga leg.; 1 male of P. fragilis collected in Areia Branca municipality, state of Sergipe (VIII2014), Santos Jr. leg.; 5 males of P. solutus collected in Ubajara municipality, state of Ceará (VII-2014), Santos Jr. leg. The material examined consists of 1 male of Perilestes eustaquioi sp. Cerci with a well developed basal lobe with rounded apex a character it shares only with P. fragilis, P. solutus and P. minor Williamson & Williamson, 1924. It differs from these species by the color characters mentioned in Table 1 and by having the anteclypeus larger than the postclypeus. Pterothorax venter yellow with a median black stripe occupying its anterior 2/3 and a reddish-brown lateral stripe occupying its posterior 1/3. Nov.: (1) head, dorsal view; (2) anterior part of pterothorax, dorsal view; (3-5) cerci: (3) dorsal, (4) lateral and (5) mediodorsal views. Anterior 1/2 black Light blue, anterior 1/3 black Bright blue, narrowly black edged
