S. basioconica

Each antennal segment had on average 5-6 (range, 3 to 12) s. basioconica (18.1 μm long, 2.25 μm base diameter) near the tip of each segment ( Fig. 5 ). These sensilla had non-flexible sockets and a thin wall pierced with numerous pores, and most likely had an olfactory function. For all of the mole cricket species, all the sensilla types were about the same size, although the s. basiconica of N. hexadactyla were shorter (7.5 μm long, 1.85 μm wide) than in the other species ( Fig. 6 ).
