description: Cernotina bispicata sp. nov. Camargos, Barcelos-Silva & Pes
(Figs. 3 A–D).
Etymology. The adjective bispicata refers to the pointy shape of the apex of tergum X, where bi (Latin) = two, spicata (Latin) = pointy.
Diagnosis. This species is similar to the preceeding C. anhaguera sp. nov., by the dorsolateral and ventromesal lobes of preanal appendages rod-like, with apical spines. These species can be distinguished from each other by the relative size of the ventromesal lobe of each preanal appendage, which is less than the half of the dorsolateral lobe in C. bispicata sp. nov., and almost as long in C. anhanguera sp. nov. The species can also be distinguished by the strongly truncate apices of the inferior appendages in C. bispicata sp. nov., and subtruncate apices in C. anhanguera sp. nov. The pointy bifurcated apex of tergum X in dorsal view in C. bispicata sp. nov., as opposed to the subtruncate apex in C. anhanguera sp. nov., also helps to separate the two species.
Description. Male. Length of each forewing 3.5 mm (n = 1). 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 trapezoidal, anterior and posterior margins each broadly excavated and posterior margin slightly broader than middle portion in ventral view (Fig. 3 C). Tergum X membranous, posteriorly narrow with deep and wide mesal notch V-shaped in dorsal view (Fig. 3 B). Preanal appendages each composed of two lobes, in lateral view with dorsolateral lobe elongate, slightly curved dorsad, with stout, black, apical spine; ventromesal lobe short, less than half as long as dorsolateral lobe, with broad base and tapering to apex, with stout, black, apical spine (Fig. 3 A). Inferior appendages in lateral view subrectangular, truncate apically, covered by fine setae; each with basodorsal lobe long, digitate, bearing some fine setae (Fig. 3 A); very dark apicomesal lobe sclerotized, crescentic in lateral view. Expanded phallus short, slightly tubular, base broader than apex, with pair of long internal spines, in subapical area (Fig. 3 D).
Female: Unknown.
Holotype male: BRAZIL: Goiás; Niquelândia; Fazenda Horto Aranha, Anglo American/Codemin; 14°25’12.00”S, 48°44’9.00”W; 18–19.i.2013; L.M. de Camargos, M.C. Almeida, and C.E.K. de Oliveira; Pennsylvania trap [alcohol] (INPA).
Biology. The specimens were collected in a fast, narrow stream within a forest fragment from Cerrado vegetation, with some deep pools along its course. Riparian vegetation of semi-deciduous trees is present all along the river. The stream has a rocky bottom with some leaves and sand in the pools.
