Subgenus Condylophora Dawwrueng, Gorochov et Suwannapoom subgen. nov.

Type species Minirhaphidophora (Condylophora) ophioglossa sp. nov.

Diagnosis. General appearance (including size of body) is similar to that of nominotypical subgenus but with distinct differences. Rostral tubercles are rather large. Male appears with 7th–10th abdominal tergites with posterior projections following ( Figs 34–36 ). The seventh tergite is present with short and roundly angular posteromedian lobe; the posterior margin of the eighth tergite appears with one rather large and acute posteromedian projection with a pair of slight convexities not far from it; the ninth tergite is shortened with a short and widely rounded posteromedian lobe; the tenth tergite is present with a pair of rather large and laterally compressed tubercles located near each other and a subacute apex. Female displays tergites that are similar to those of male specimens, but the projection of the eighth tergite is shorter and rounded at the apex. The projection of the ninth tergite is slightly shorter than in the male, and the tubercles of the tenth tergite are smaller and almost lobule-like ( Fig. 39 ). Epiproct is indistinctly separated from this tergite and triangular in male specimens with an apical part that is narrow, almost truncated, curved upwards and having a bifurcate apex that is more or less similar to a snake’s tongue ( Figs 34–37 ). In the female, the epiproct is present with a simple rounded apex ( Fig. 39 ). The genital plate of the male is present with large (long) subcylindical styles and a moderately long posteromedian lobe between them ( Fig. 38 ). The female genital plate is triangular with a distinct posteromedian spine ( Fig. 40 ) and small lateroproximal lobes. The ovipositor is rather short and wide, slightly curved upwards and with an acute apex and ventral margin at the distal part of the lower valves that are distinctly serrulate ( Fig. 41 ).

Comparison Differences of this subgenus from the nominotypical specimen are provided in the key above.

Etymology The new subgeneric name originated from the Latinized Greek word “condylus” (tubercle) and the generic name “ Rhaphidophora ”. This is because the male of this subgenus has a pair of characteristic tubercles on its tenth abdominal tergite.
