description: Tinodes kebala, new species
Fig. 14–17
This species is distinguished by the strongly dorsally expanded tergite IX with posterolateral band of posterad oriented megasetae; and in the paraproctal process chaetotaxy involving an anterior pair of extremely long megasetae that are directed dorsad and loop mediad over tergite IX, and a series of shorter megasetae of different thickness along the lateral margin.
Male genitalia (Fig. 14–17). In lateral view, sternite IX with 1 pair sharply triangular, anterad oriented processes at anteroventral corner (Fig. 14); posteroventrally strongly produced into long, rectangular lobes. Tergite IX originating from dorsal basis of superior appendages about at mid-height of sternite IX; ventral margin weakly concave along its length (Fig. 14); developing into large dorsal, rectangular process and bifid apex (Fig. 14, 15); dorsal process with series of short megasetae in band immediately before posterior margin (Fig. 14); apices with laterad oriented spine (Fig. 15). Superior appendages originating at about mid-height of posterior margin of sternite IX; slightly laterally flattened; with setae confined to distal two-thirds; slightly bent posterad immediately after mid-length (Fig. 14); diverging in dorsal view (Fig. 15). Inferior appendage slightly longer than superior appendages (Fig. 14); inferior appendage basal plate apodeme slender, with gradually widening anterior apex in lateral view (Fig. 14); very slender, needle-shaped in dorsal and ventral views (Fig. 15, 17); posterior part 4-branched in lateral view, (Fig. 14); dorsal branch broadest with rounded apex; with 2 pairs megasetae at lateral surfaces; ventral branch forming ridge on coxopodite; in ventral view visible as single, slender process along longitudinal axis of genitalia (Fig. 17). Paraproctal process complicated, originating from dorsal apex of sternite IX; divided into long central branch and pair of slightly longer lateral branches. Central branch proximally straight with ventrad bending apex in lateral view (Fig. 14); main part forming sheath with central, dorsad curving tube and apparently single long, pointed, sclerous processes on left side (Fig. 14, 15). Lateral branches of paraproctal process straight along their lengths (Fig. 10); running parallel apicad (Fig. 16); anterior pair of megasetae extremely long, proximally oriented anterodorsad before curving dorsad and looping mesad and crossing over tergite IX (Fig. 14, 15, 16); 2 pairs very thick megasetae present at dorsal margin further distally (Fig. 14, 16) followed by lateral row of about 8 megasetae of various thickness (Fig. 14, 16). Coxopodites oval in lateral view (Fig. 14); ventrally fused mesally before half-length (Fig. 17); ventral apices with irregular surfaces (Fig. 14, 17); apical, smooth processes present immediately above ventral apices, oriented posteromesally, without setae (Fig. 14, 17). Harpagones (Fig. 14, 17) very short, setose.
Holotype male: MALAYSIA: Perak, Halong str., 19.xi.1993, light [G. S. Robinson] (OPC, in alcohol).
Etymology. kebala, from “ kebala ” meaning single in Sanskrit, referring to the single, prominent dorsal lobe of tergite IX.
