Helicopsyche (Feropsyche) catoles, new species

(Figs. 1 A–1F)

Diagnosis. Helicopsyche catoles n. sp. is easily distinguished from congeners by the following features: Inferior appendages clavate, each with a posteroventral projection, bearing 2-4 setae, and tergum X with a notched apex and with a pair of longitudinal rows of short setae best seen in dorsal view. The new species is most similar to H. succincta, particularly in the inferior appendages each widening in its distal half and with an undulate dorsal margin in this new species, and with H. angeloi Holzenthal, Blahnik & Calor 2016 in a distinct protuberance on the ventral margin at midlength of each inferior appendage of the new species.

Male. Length of each forewing 3.69–4.86 mm (n = 13) and of each hind wing 2.83–3.60 mm (n = 13).

Abdomen. Sternal process VI long, in lateral view tubular along its length, covered with tiny setae (Fig. 1 F). Genitalia. Segment IX in lateral view with anteromesal margin well developed, anteroventral margin slightly concave, anterior lobe well developed and triangular, lateral apodeme developed (Fig. 1 A); in dorsal view, with anterior margin hyperboloid (Fig. 1 D); in ventral view, without posterior process, with anterior margin sinuous and posterior margin slightly concave (Fig. 1 E). Tergum X, in lateral view with erect setae along dorsal margin, dorsal margin nearly straight, apex rounded (Fig. 1 A); in dorsal view quadrangular, parallel-sided, with notched apex and with pair of longitudinal rows of short setae (Fig. 1 D). Superior appendages, in lateral view originating dorsolaterally, rounded, with long setae (Fig. 1 A). Inferior appendages, in lateral view clavate, widening distally, each with undulating ventral and apicodorsal margins with long setae; posteroventral corner with 2–4 setae, its apex tapering and curving mesad (Fig. 1 A); in ventral view narrow and tapering from base to apex, with longitudinal, setose, dorsomesal carina on most of distal half (Fig. 1 E); basomesal lobe well developed and ovate in lateral and ventral views (Figs. 1 A, 1E). Phallus, in lateral view tubular, strongly downcurved; phallobase slender, slightly inflated at base, posterior region with dorsal margin membranous (Fig. 1 B); in ventral view tubular, slightly narrower in middle (Fig. 1 C).
