description: Tinodes suksa, new species
Fig. 21–23
This species is distinguished by the posteriorly produced sternite IX; the very long and apically dividing paraproctal process originating from sternite IX well below mid-height of genitalia and bearing 1 pair of very large posterolaterad megasetae at mid-length; and the extremely narrow tergite forming a narrow band along the length above the paraproctal process.
Male genitalia (Fig. 21–23). In lateral view, sternite IX ventral parts strongly producing posterad, dorsal parts expanding anterad before ending in paraproctal process below mid-height of genitalia (Fig. 21); in ventral view nearly oval, with slightly incising anterior apex (Fig. 23). Tergite IX long, originating from dorsal basis of superior appendages; sigmoid, narrow tuboid laterally, continuing dorsally above paraproctal process (Fig. 21, 22); in dorsal view slightly diverging before fusing as far out as apices of coxopodites (Fig. 21, 22); without setae or megasetae. Superior appendages originating from dorsal-most part of sternite IX; undulating distad; about 2 times wider than tergite IX along its length in lateral view (Fig. 21); in dorsal view widest at mid-length (Fig. 22); setae restricted to distal two-fifths. Inferior appendage as long as superior appendages (Fig. 18); basal plate apodeme gradually widening anterad into slightly up-curving, club-shaped apex (Fig. 21); in ventral view (Fig. 23) narrow before ending in anterior spine (Fig. 23); posterior part ending in coxopodite basis (Fig. 21). Paraproctal process basally wide in lateral view (Fig. 21); orienting anterodorsad before looping posteroventrad; divided into dorsal and ventral processes around mid-length its length (Fig. 22); dorsal process laterally narrowly bifid from midlength its length; ventral process longer than dorsal process, widely bifid immediately after large lateral megasetae (Fig. 22); dorsal process smooth; ventral process with 1 pair very large, posteroventrad orienting megasetae, followed by lateral pair of rows of 3 short megasetae; branches of dorsal process curving dorsomesad apically; branches of ventral process oriented posteroventrad and crossing apically (Fig. 22). Coxopodites as broad as posterior part of sternite IX in lateral view (Fig. 21), dorsal and ventral margins nearly parallel (Fig. 21); ventrally fused mesally at three-fourths their length (Fig. 23); apically separated by narrow slit; producing laterally into posterolaterad setose lobes; with 1 pair prominent, smooth processes originating from posterior apices, in ventral view directed laterad before mesad curving apices (Fig. 23). Harpagones absent.
Holotype male: MALAYSIA: Perak, Halong str., 29.xi.1993, light [G. S. Robinson] (OPC, in alcohol).
Paratypes: same data as holotype, except 8.xii.1993 — 1 male; same, except in NRM; MALAYSIA: Pahang Genting Tea Estate, 2000 ft., xi.1981, Malaise trap by stream [K. R. Truck] — 5 males; same, except 4 males in NRM.
Etymology. suksa, from suksa, meaning thin in Sanskrit, referring to the slender body and genitalia of this species.
