description: Tinodes caolana, new species
Fig. 7–9
This species is distinguished by the shape of the paraproctal process which is divided into a high and narrow central branch and a pair of slightly shorter lateral branches with 9 pairs of megasetae; the basal part being very thick, with a large membranous area.
Male genitalia (Fig. 7–9). In lateral view, sternite IX with 2 small anterad oriented, rounded processes ventrally and at mid-height; posteroventrally broadly produced into rounded lobes. Tergum IX originating from superior appendages below mid-height of sternite IX; anteriorly forming straight, narrow stalk in lateral and dorsal views (Fig. 7, 8); distal part broadening dorsally (Fig. 7) before producing and narrowing posterad before slightly curving ventrad. In dorsal view, anterior stalks about equally broad before ending into anterior rays of posterior part; posterior part distally fused into plate-like apex with lateral expansions and central posterior lobe (Fig. 8). Superior appendages originating from sternite IX below mid-height; slightly sigmoid; club-shaped; broadest at distal half; setae restricted to distal two-thirds (Fig. 7, 8). Inferior appendages slightly longer than superior appendages (Fig. 7); inferior appendage basal plate apodeme broad, club-shaped in lateral view (Fig. 7); very slender, needle-shaped in ventral view (Fig. 9); posterior parts with 2-branched claws (Fig. 7); dorsal apices hooking ventrad, ventral apices pointing posteroventrad; without setae on lateral surfaces; in ventral view with right and left branches situated very closely, visible between harpagones (Fig. 9). Paraproctal process originating from dorsal apex of sternite IX; divided into central branch and pair of lateral branches. Central branch sigmoid and very broad in lateral view, angling posterad before mid-length (Fig. 7), slender in dorsal view (Fig. 8). Lateral branches slightly sigmoid (Fig. 7), nearly as long as central branch; with 3 pairs very long megasetae at dorsal and ventral margins originating immediately after mid-length of branch; 6 pairs shorter megasetae located in row along dorsal apical margin (Fig. 7). Basal part of paraproctal process broad (Fig. 7, 8) with large membranous areas; about parallel-sided in dorsal view (Fig. 8); in lateral view with convex dorsal margin. Coxopodites oval in lateral view, with prominent posterodorsal branch incised at ventrobasal margins and posterior apical margins (Fig. 7); in ventral view fusing mesally at basal three-fourths (Fig. 9). Harpagones setose, originating from ventrodistal corner of coxopodites; slightly clubshaped in lateral view, straight; pointing posteromesad in ventral view (Fig. 9).
Holotype male: VIETNAM: Lamdong, Baoloc, Baco str., 26.x.1988, light [J. Oláh] (OPC, in alcohol). Etymology. caolana, from “caolan”, the name of a small tribe living in the area from where the species was collected.
