Figure 8
Types of distribution of the mechanosensilla on the dorsal surface of the labium in the Corixoidea. Sensilla placed in the transverse bands or scattered unevenly on the dorsal labial surface ((a) and (b)) and sensilla scattered unevenly on the labial surface (c). (a) Diaprepocoridae; Diaprepocoris zealandiae, two and half of bands, three rows (r1, r2, r3) of semicircular grooves with a pore, two rows of ribbon-like sensilla. (b) Corixidae; six bands, three rows (r1, r2, r3) of semicircular grooves with a pore, two rows of ribbon-like sensilla. (c) Cymatiinae; ribbon-like sensilla (RBS1, RBS2) and peg sensilla (PES).
