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.
