Each second lateral cervicalsclerite articulates with a small, medio-ventral pro-jection of the adjacent pronotal flange. In the ventral neck membrane, immediately be-fore the prostemum, are located small sclerites; theanterior of which is smaller than the posterior (). Crampton (1926) designated the first as aninterstemite and the second as the presternum (an an-terior detachment of the prostemum). In the presentwork these are simply designated anterior and poste-rior ventral cervical sclerites. Ahead of these, betweenapices of the first cervical sclerites, are two membra-nous domes which are densely setose in ClothodaEnderlein. Similar setose domes are found in mem-branes lateral to these apices. These are termed latero-ventral cervical sclerites.
