Key to the known male Bhutanese Diestramima

1) Male posteromedian projection of 7 th abdominal tergite long covering paraproct from above (Fig. 6E & Fig. 8E).......... 2

- Male posteromedian projection of 7 th abdominal tergite short covering only proximal half of paraproct (Fig. 7E, Fig. 9E & Fig. 12E).................................................................. ………………………….………….4

2) Male posteromedian projection of 7 th abdominal tergite without prominent formation of lateral ridges (concave) in proximal half surface, apex obtusely rounded with inconspicuous notch; paraproct triangular with a short finger-like projection (Fig. 8C–E)........................................................................... D. minjiwoonga sp. nov.

- Male posteromedian projection of 7 th abdominal tergite rather high with lateral ridges in proximal half, apex distinctly notched (Fig. 6E, Fig. 10E, & Fig. 11A); paraproct long and finger-like projection in distal half (Fig. 6C, Fig. 10C, & Fig. 11C).... 3

3) Male posteromedian projection of 7 th abdominal tergite gradually narrowing with distinct expanded notched apex; paraproct long with finger-like projection in distal half (Fig. 6C–E).............................. D. tsongkhapa (Würmli, 1973)

- Male posteromedian projection of 7 th abdominal tergite long, obviously surpassing paraproct, parallel from both sides, almost flat and curved downwards in distal half with apex curved inwards and acutely notched (Fig. 10C–F & Fig. 11B–C).......................................................................................... D. phubdorjia sp. nov.

4) Male posteromedian projection of 7 th abdominal tergite straight and flat but shallowly grooved from dorsomedial until apex, almost parallel lateral edges and truncate with small notch at median part of apex (Fig. 12B–C)....... D. samkhara sp. nov.

- Male posteromedian projection of 7 th abdominal tergite high and slightly curved gradually narrowing towards apex (Fig. 7E & 9E)................................................................................................ 5

5) Male posteromedian projection of 7 th abdominal tergite very short not extending beyond tenth tergite, gradually narrowing, truncate or slightly convex apex (Fig. 7B–D). Adult female larger than adult male................ D. matermagna sp. nov.

- Male posteromedian projection of 7 th abdominal tergite short covering proximal half of paraproct, narrowing to form almost parallel edges towards apex, truncate apex with slightly bent downwards (Fig. 9B–E). Superior prolateral and retrolateral edges of hind tibiae bear>50 minute spines.................................................. D. multidenticuli sp. nov.
