description: Tinodes gapbona, new species
Fig. 10–13
This species is distinguished by the shape of the paraproctal process that is divided into a main central branch that is sub-divided before apex, and a short pair of lateral branches with ventral megasetae in apical group. The shape of the posterior branches of the inferior appendage are divided into short up-curving ventral tooth and long, ventrally looping dorsal branch. Tinodes gapbona, new species is similar to Tinodes achaemenides Malicky & Chantaramongkol 1996 with an asymmetrical paraproctal process forming a sheath around a pair of sclerous processes, similar inferior appendages, and a pair of ventrad curving apical processes on the coxopodite.
Male genitalia (Fig. 10–13). In lateral view, sternite IX with 1 pair of finger-like, anterad oriented processes above the anterad produced anteroventral corner; posteroventrally produced into long, rounded lobes. Tergum IX originating from basis of superior appendages well below mid-height of sternite IX; ventral margins straight along their lengths (Fig. 10); irregularly broadening distally in lateral view (Fig. 10); with central, U-shaped incision at posterior margin in dorsal view (Fig. 12). Superior appendages originating well below mid-height of sternite IX; club-shaped; slightly bent posterad immediately after mid-length (Fig. 10); diverging in dorsal view (Fig. 12). Inferior appendages slightly longer than superior appendages (Fig. 10); inferior appendage basal plate apodeme slender, with club-shaped anterior apex in lateral view (Fig. 10); very slender, needle-shaped in dorsal and ventral views (Fig. 12, 13); posterior part 2-branched, claw-like (Fig. 10); dorsal apex strongly looping ventrad, with 2 pairs setae near margin on lateral surface; ventral apex pointing posterad; in ventral view visible as single, slender process along longitudinal axis of genitalia (Fig. 13). Paraproctal process complicated, originating from dorsal apex of sternite IX; divided into long central branch and pair of shorter lateral branches. Central branch proximally straight and distally curving ventrad in lateral view (Fig. 10); main part forming sheath with central, dorsad curving tube and pair of long, pointed, asymmetrical sclerous processes (Fig. 10, 11, 12). Lateral branches of paraproctal process oriented ventrad before curving posterad at mid-length (Fig. 10); densely covered by stout, ventrad and laterad oriented megasetae at apex (Fig. 10); in dorsal view left and right branches converging towards mid-length before diverging apices (Fig. 12). Coxopodites oval in lateral view (Fig. 10); in ventral view fused mesally at basal three-fourths (Fig. 13); apices with lateral, finger-like process with short setae along mesal margin (Fig. 13); additional slender process originating from basis of harpagones being sigmoid in ventral view (Fig. 13) and strongly looping ventrad in lateral view (Fig. 10). Harpagones setose, originating from apex of coxopodites; slightly club-shaped in lateral view, straight (Fig. 10); in ventral view (Fig. 13) cone-shaped, slightly directed mesad (Fig. 13).
Holotype male: VIETNAM: Hoabinh towards Dabac, 21.x.1986, light [J. Oláh] (OPC, in alcohol).
Etymology. gapbona, from “gap bon”, meaning four fold in Vietnamese, referring to the fourfold appearance of the gonocoxite and paraproctal process.
