Like Aprostocetus kurandensis, excepting the concolorous 

 femora in this species, but the antennae with two ring- joints and 

 the abdomen produced into a slender Stylus as often in species

 conically acuminate distad, the ovipositor exserted a slight distance. 

 Also the joints of the funicle are longer, each over or about twice
