Figs 59–60

Diagnosis

Hind femur robust, 3.5× as long as wide ( Fig. 60F ); metasomal carapace about 1.9× as long as wide ( Fig. 60J ); antenna brown but basally yellow ( Fig. 60E ); temple honeycomb-like sculptured ( Fig. 60C ); metasomal carapace yellowish brown but third tergite more or less darkened ( Fig. 60J ); mesopleuron and metasoma honeycomb-like sculptured ( Fig. 60I–J ); face and frons rugulose ( Fig. 60A–B ).

Etymology

Named after the laterally finely rugulose frons; ‘ rugula ’ is Latin for ‘small wrinkle’.

Distribution

China (Taiwan).

Remarks

Phanerotomella rugulosa sp. nov. is similar to P. brevifemorata sp. nov. because of the brown flagellum except basally yellowish, and the temple in dorsal view narrowing behind the eye. However, P. rugulosa can easily be distinguished from P. brevifemorata by having vein m-cu postfurcal (antefurcal in the latter), the second submarginal cell sessile (distinctly petiolate in the latter), and the lateral border of the metasoma in dorsal view less curved (more curved in the latter).
