description: Tinodes samkuca, new species
Fig. 4–6
This species is distinguished by the posteriorly 3-branched gonocoxite; a very long tergite IX that in dorsal view ends into a narrow, posterad oriented parallel-sided projection; and, in lateral view, a distally narrowing and sigmoid paraproctal process bearing 5 pairs strong megasetae.
Male genitalia (Fig. 4–6). In lateral view, sternite IX with 2 anterad oriented, pointed processes ventrally and mid-height; posteroventrally produced into rounded lobes; apex of anterad oriented processes at midheight with weak suture curving ventrad to midlength of ventral face of sternite IX (Fig. 4, 6). Tergum IX originating from small knob situated immediately above mid-height; anteriorly forming straight, wide stalk in lateral and dorsal views (Fig. 4, 5); distal part broadening dorsally (Fig. 4) before producing posterad and curving ventrad. In dorsal view, anterior stalks slightly widening posteriorly; posterior part very broad basally before strongly narrowing before mid-length; apex produced into narrow, posterad oriented parallel-sided projection (Fig. 5). Superior appendages originating from bases of tergite IX; slightly sigmoid; setae restricted to distal half; slightly exceeding apex of tergite IX (Fig. 4). Inferior appendages slightly longer than superior appendages (Fig. 4); inferior appendage basal plate apodeme broad, club-shaped in lateral view (Fig. 4); very slender, needle-shaped in dorsal and ventral views (Fig. 5, 6); posterior parts broadly claw-shaped in lateral view; apices slightly pointing ventrad; with 2 small, laterad oriented megasetae on lateral surfaces; in ventral view apices very slender, oriented mediad before curving posterad, visible medially of harpagones (Fig. 6). Paraproctal process originating from dorsal apex of sternite IX; sigmoid in lateral view (Fig. 4); dorsobasal margin straight, produced posterad (Fig. 4), pyriform in dorsal view (Fig. 5); basal part oriented ventrad before slightly looping dorsad; with 3 pairs megasetae in row along ventral margin, followed by small megasetae in ventral group; divided into 2 tuboid branches (Fig. 5) with 2 pairs long, apical megasetae (Fig. 4, 5). Gonocoxites with basal half fused ventrally (Fig. 6); coxopodites divided apically into large dorsal and short ventral branches; harpagones situated between coxopodite branches (Fig. 4, 6); dorsal branches without setae; ventral branches with single apical, mediad oriented seta. Harpagones nearly as long as dorsal branch of coxopodites, covered by strong setae (Fig. 4, 6).
Holotype male: MALAYSIA: Perak, Halong str., ix–x.1993, light [G. S. Robinson] (OPC, in alcohol). Etymology. samkuca, from “samkuc”, meaning shrunk in Vietnamese, referring to the small size of this species.
