Lopes, Sonia Maria, Oliveira, Edivar Heeren De & Assumpção, Mariana, 2014, Two new species of Blaberidae (Blattaria) collected in the Santa Lúcia Station, Espírito Santo State, Brazil, Zootaxa 3779 (4), pp. 487-492 : 490

Epilampra pereirae sp. nov.

( Figs. 9–16 )

Measurements (mm). Holotype male: Total length 22.0, length of pronotum 4.5, width of pronotum 5.5, length of tegmen 20.0, width of tegmen 5.5.

General coloration glossy brown. Head yellowish light-brown, vertex and interocular space covered with black spots; ocelli orangish; frons yellowish with two symmetrical parallel dark-brown spots ( Fig. 9 ). Antennae brown, golden-tomentose. Pronotum grayish brown, entirely covered with dark brown dots ( Fig. 10 ). Legs brown with whitish pulvilli. Tegmina brown, with marginal and scapular field bearing distinct dark brown dots, becoming lighter in discoidal and anal fields.

Head subtriangular, vertex slightly exposed under pronotum in dorsal view; interocular space wide, measuring about half distance between bases of antennal sockets; ocelli large and deflected. Antennae long, tomentose, extending past apex of abdomen; maxillar palpi tomentose, with apical segment dilated and larger than others.

Pronotum transverse, convex with two grooves diverging posterolaterally from the base, edges deflected, with rounded contour; base angular and sinuous. Legs spiny. Anteroventral margin of cephalic femur with five wellspaced robust spines extending to middle, followed by a row of 12 minute spines extending to apex plus two robust apical spines (Type B2); posteroventral margin with three robust spines, one in middle region, one next to basal third, and one apical; middle and posterior femora each with ventral margins bearing four robust and well-spaced spines, one of which is apical; genicular spine present; pulvilli present on all tarsomeres; arolium present, claws symmetrical and ventrally serrated. Tegmina long, reaching past apex of cerci; marginal field short, narrow and deflected; scapular field long and narrow, veins arranged obliquely; discoidal field ample, veins arranged longitudinally; anal field ample, with 12 or more axillary veins. Wings developed, apical triangle present; costal sector with apex of branches of radial vein not dilated; anal field folded in a fan.

Abdominal supranal plate with slight median indentation between the cerci, which are short, bristly and widened ( Fig. 11 ). Subgenital plate asymmetrical, pointed styles placed laterally to apex of plate ( Fig. 12 ). Left phallomere slightly developed, shaped as an inverted Y, with two projections, one of which is strongly sclerotized ( Fig. 13 ). Median sclerite with strongly acute apex, markedly sclerotized, forming an arrow shape ( Figs. 14 and 15 ). Right phallomere well developed, projecting pre-apically, with its apex acute and markedly bent over ( Fig. 16 ).

Type material. Holotype male, Brazil, Espírito Santo, Santa Teresa, Santa Lúcia Biological Station, 16.II.2008, Janira Martins Costa, Sueli Maria Pereira and Cesar Carriço, colls.

Etymology. The species name honors the biologist Sueli Maria Pereira of the Museu Nacional.

Comment. The species is similar to E. thunbergi Princis, 1949 , but the apical median sclerite and right phallomere are more slender than it that species. Both E. thunbergi and E. pereirae n. sp. are included in the burmesteri group, subgroup B ( Roth 1970).
