description: Cernotina pesae sp. nov.
Figs. 9–12
Description. Male. Length of each forewing 2.8–3.2 mm. General color, in alcohol, pale brown; head and antennae light yellow, legs pale yellow with dark brown setae, meso- and metathorax pale brown, setae of the head and thorax dark brown, wings almost hyaline, abdomen ventrally stramineous and dorsally dark brown.
Male genitalia. Sternum IX deeply excavated anteriorly, forming two lobes (Fig. 11). Tergum X divided mesally into two short lobes, with short setae on all surfaces (Fig. 10). Preanal appendages with dorsolateral lobes apparently absent (Figs. 9, 10); and with ventromesal lobes bipartite; each with dorsal branch elongate, apex curved inward, bearing stout, dark, apical spine; ventral branch flattened, with some short setae, and with finger-shaped projection laterally (Figs. 9, 10). Inferior appendages long, with transverse striae mesally, each with apex bearing sclerotized hood-shaped structure; apicomesal lobe short and sclerotized; basodorsal lobe displaced apicad, subtriangular and with a row of five short spine-like setae (Figs. 9, 11). Phallus tubular (Fig. 12), internally with two dark spines and phallicata sclerite bearing two parallel branches in dorsal view.
Remarks. Cernotina pesae, sp. nov. seems to be related to Cernotina subapicalis Flint, 1971. They are especially similar in having the basodorsal lobe of each inferior appendage displaced apicad. Nevertheless, C.
pesae can be easily distinguished by the presence of a sclerotized hood-shaped structure at the apex of each inferior appendage, by the more apical displacement of the short basodorsal lobe of the inferior appendage, and by the dorsal branch of each ventromesal lobe of the preanal appendage being longer and bearing an apical stout spine.
