description: Tinodes kemnounga, new species
Fig. 1–3
This species is distinguished by the tripartite segment IX, the very short paraproctal process, the very long inferior appendages with large, club-shaped dorsal branch, and the coxopodites densely covered by small spines on the ventral surface.
Male genitalia (Fig. 1–3). In lateral view, sternite IX forming 3 pairs prominent plates; ventral plates anteriorly conical; median plates slightly shorter than ventral plates, dorsally pointing anterad; dorsal plates nearly quadrangular with single posterodorsal and posteroventral processes. In dorsal view (Fig. 2) sternite IX producing anterad at center, immediately opposite of paraproctal process (Fig. 2). In ventral view sternite IX with short, central lobe with short marginal megasetae (Fig. 3). Long, slender, tube-shaped process originating immediately below paraproctal process possibly forming phallus (Fig. 1, 2). Pair of flat, lateral processes originate at or immediately below dorsal plates of sternite IX (Fig. 1, 2). In ventral view (Fig. 3) sternite IX narrowing centrally. Tergum IX originating from posterodorsal part of dorsal plates of sternite IX; narrow at basis; directed posterad along its length; tapering apically in lateral view (Fig. 1); wide in dorsal view (Fig. 2), slightly narrowing distally, apex truncate; with 2 pairs of setae immediately before apical margin. Superior appendages tube-shaped; basal one-third oriented posteroventrad before bending posterad; setae present at distal two-thirds. Inferior appendages 2.5 times longer than superior appendages; oriented posterad along their lengths, except slightly bending dorsad at anterior one-fifth; dividing at anterior one-fifth into dorsal branches posteriorly exceeding superior appendages, with wide, club-shaped distal two-fifths; dorsal branches divided by transversal articulation at two-fifths their lengths; sclerous process large, sharply pointing posterad, with dentose dorsal and ventral margins, apices reaching as long as apex of dorsal branch of inferior appendages. Ventral branch of inferior appendages (Fig. 1) curving ventrad before ending in coxopodites. Paraproctal process minute, as long as length of sternite IX in dorsal view (Fig. 2); oriented posterad, with small megasetae along posterior apex (Fig. 1, 2). In ventral view (Fig. 3) coxopodites narrowing posterad in lateral and ventral views (Fig. 2, 3); with short megasetae centrally on ventral surface towards harpago, delimited laterally by short setae (Fig. 3). Harpago slightly bending posteroventrad from ventral margin of coxopodites (Fig. 1); in ventral view (Fig. 3) fusing at basal one-third before dividing into pair of posterad oriented, apically inwardly curving branches.
Holotype male: VIETNAM: Bac Thai Province, Quang Chu, 24–25.v.1987, light [J. Oláh] (OPC, in alcohol).
Etymology. kemnounga, from “khiem nhuong”, meaning modest in Vietnamese, referring to the difficulties in discovering this small animal among the numerous other caddisflies in the sample.
