Barcelos-Silva, Camargos & Pes ( Figs. 5 A–D) Cernotina sp. 3, Barcelos-Silva et al . 2012, pp. 1279. Etymology. This adjective lanceolata refers to the lance-like shape of the superior branch of the dorsolateral lobe of each preanal appendage, where lanceolata (Latin) = lanceolate. Diagnosis. Cernotina lanceolata sp. nov. is similar to C. perpendicularis Flint 1971 in the shape of the preanal appendages in lateral view. Cernotina lanceolata sp. nov. can be distinguished by the shape of tergum X which, in lateral view, is more or less parallel-sided and blunt apically (tapered in C . perpendicularis ). Furthermore, in C. lanceolata sp. nov. the internal dorsal margin of tergum X is covered with many short, stout setae (absent in C. perpendicularis ). The length of the dorsal branch of the dorsolateral lobe of each preanal appendage exceeds half of the length of tergum X in dorsal view in C. lanceolata sp. nov. , but in C. perpendicularis it does not reach the middle of tergum X. Description. Male. Length of each forewing 3.5–3.6 mm (n = 2). General color, in alcohol, yellowish brown; antennae pale yellow, tibia and tarsus of each foreleg with short, dark brown setae, mid- and hind legs with golden setae. Male genitalia : Sternum IX short, subquadrate, anterior margin broadly excavated and posterior margin more deeply and acutely incised ( Fig. 5 C). Tergum X semi-membranous, in dorsal view divided basally into two lobes, tapering apically and curved mesad, each lobe with stout, black, apical spine, internal dorsal margin covered with many small setae ( Fig. 5 B), and long setae on its external surface. Preanal appendages, in lateral view, each with dorsolateral lobe bifurcate basally; dorsal branch longer, tapering apically with two small triangular spines, one apical and other subapical, ventral branch short, subtriangular with apex turned ventrad; ventromesal lobe quadrate, with small concavity in posterior margin ( Fig. 5 A). Inferior appendages subquadrate in lateral view, covered by setae; each with basodorsal lobe long, digitate, apically rounded with six setae ( Fig. 5 A); apicomesal lobe sclerotized, forming two small sharp projections in ventral view ( Fig. 5 C). Phallus tubular, with pair of internal spines (phallus not expanded) ( Fig. 5 D). Female : Unknown. Holotype male: BRAZIL : Espírito Santo; Linhares, Praia do Minotauro; 19°19'05.8''S , 40°05'11.9''W ; 22.xi.2009 ; E.A. Raimundi, F.F. Salles, P. Barcelos-Silva, and P.V.A. Brito; white sheet with white light [alcohol] (CZNC). Paratype : BRAZIL : Espírito Santo; Pedro Canário, Cachoeira da Mata ; 18°12'10.8''S , 40°04'37.9''W ; 29.iii.2011 ; E.A. Raimundi, F.C. Massariol, K.D.C. Bertazo, and P.V.A. Brito; white sheet with mixed white light; 1 male [alcohol] (INPA). Biology. The specimens were collected in two different localities: Lagoa Juparanã, one of the largest lakes in Brazil , where the bottom is mostly sandy; and a stream crossing a little fragment of Atlantic Forest, with a stony bottom.
