1 | Aedeagus not pubescent; aedeagal apodeme as long as or longer than aedeagus (fig. 4CF13, fig. 40L14, fig. 47L14) |
|
– | Aedeagus pubescent (except for |
|
2 | Foreleg tarsomere II with seven or eight pegs (fig. 4BF13). Epandrial apodeme medially narrower than epandrium (fig. 4CF13). Aedeagal apodeme much longer than aedeagus (fig. 4CF13). Distal, narrow part of oviscapt much shorter than proximal, broad part, apically shaped like arrowhead, with a pair of stout, peg-like ovisensilla at apex (fig. 4BF13) |
|
– | Foreleg tarsomere II with six pegs (fig. 14L14, fig. 15L14). Epandrial apodeme well developed into distally tapering, triangular extension strongly projected anteriad, twice as long as epandrial width (fig. 38L14, fig. 45L14). Aedeagal apodeme slightly longer than aedeagus (fig. 40L14, fig. 47L14). Distal, narrow part of oviscapt rod-shaped, slightly shorter than proximal, broad part, with only trichoid ovisensilla (fig. 43L14, fig. 50L14) |
|
3 | Wing C3F index < 2/3. Distance between antennal sockets same as socket width. Distal, narrow part of oviscapt constricted subbasally on dorsal margin (fig. 43L14) |
|
– | Wing C3F index > 2/3. Distance between antennal sockets larger than socket width. Distal, narrow part of oviscapt finger-like, not constricted subbasally on dorsal margin (fig.50L14). |
|
4 | Labellum with 14 pseudotracheae per side. Distal, narrow part of oviscapt broadly truncate apically, much shorter than proximal, broad part (fig. 1FO87, fig 2HF13). |
|
– | Labellum with 17 or more pseudotracheae per side. Distal, narrow part of oviscapt not or only slightly truncate apically, ca 2/5 or longer the length of proximal, broad part. |
|
5 | Epandrium notched above basal corner of epandrial ventral lobe (fig. 30L14). Ventral lobe apically with a grooved, finger-like peg (fig. 32L14). Distal, narrow part of oviscapt twice as long as proximal, broad part (fig. 36L14) |
|
– | Epandrium not notched along posterior margin. Ventral lobe apically with an ungrooved, inward-curved peg or thick spine. Distal, narrow part of oviscapt as long as or shorter than proximal, broad part. |
|
6 | Labellum with 17 pseudotracheae per side. Epandrium broad, with short ventral lobe apically inlaid with thick, long, inward-curved, spine-like seta (Fig. |
|
– | Labellum with ≥ 21 pseudotracheae per side. Epandrium with long ventral lobe apically inlaid with short peg. |
|
7 | Epandrium with setae on posterior margin in addition to those on ventral lobe (fig. 24L14). Distal, narrow part of oviscapt nearly as long as proximal, broad part (fig. 28L14) |
|
– | Epandrium with no setae on posterior margin above ventral lobe (fig. 3CF13, Figs |
|
8 | Labellum with 21−22 pseudotracheae per side. Ventral lobe of epandrium well developed, narrowing distally in lateral view, scabbard-like, with 3 long setae on dorsosubbasal margin, apically inlaid with a short peg; cercus with slightly projected ventral apex (fig. 3CF13). Aedeagal apodeme ca 3/4 the length of aedeagus (fig. 3DF13). Distal, narrow portion of oviscapt narrowing distally, gently curved dorsad (fig. 3GF13) |
|
– | Labellum with 34 pseudotracheae per side. Ventral lobe of epandrium prolonged like a rod, distally slightly broadened in lateral view, with 2 long and 1 medium-length setae on its insertion, apically inlaid with a relatively long, claw-like peg; circus ventrally lacking projected apex (Fig. |
