Symplocodes Hebard, 1929

Symplocodes Hebard, 1929: 75; Princis, 1971: 1129; Roth, 1995: 995; Roth, 1999: 133.

Type species

Hemithyrsocera ridleyi Shelford, 1912 .

Diagnosis (Partly after Roth, 1995)

Vertex with interocular space slightly less than the distance between antennal sockets. Tegmina and wings fully developed (except the female of Symplocodes impar, which are reduced). Tegmina with an apical posterior branch of radius (AP. POST. BR) near middle of main stem of radius, median and cubitus veins longitudinal; hind wings with some of Rs and R1 slightly thickened distad, cubitus vein curved, simple, or with only one complete branch and incomplete branch absent . Front femur Type A 3 (Figures 2C, 3C, 4C, 6C, 7C), pulvilli on four proximal tarsomeres, tarsal claws with inner margins heavily and conspicuously dentate, arolia present. Male: seventh abdominal tergum specialized with transparent region in centre, and with lateral lobes present or absent; subgenital plate strongly asymmetrical, with more or less complex structures on left side in dorsal view, most of left stylus absent (except S. juxtaridleyi); hook-like L3 short, on left side.

Remarks

Roth (1995) stated the only character that clearly separates Symplocodes from Hemithyrsocera is the distinctly toothed tarsal claw. Pseudophyllodromiinae genus Chorisoserrata also has toothed claws (Figure 8A – C) but it differs from Symplocodes in terms of characteristics as follows: eyes reduced, interocular space distinctly wider than the distance between antennal sockets; pronotum subelliptical but hind margin nearly truncate; median phallomere very long and slender, totally extending beyond the end of body with apical part protruding. The claw dentation of these two genera differs in some aspects morphologically and may result in (or from) different behaviours or habitats; the details are given in our entry for discussion.
