The setae, situated on scapular level, are short; the length of the rest being quite reduced. The appearance of one of them can be clearly seen in Fig. 30. In adult males, the shield covers the dorsal surface and is rigid. Its appearance can be observed in Fig. 31. The cervical grooves run divergently in an anteroposterior direction, on the level of leg II where the eyes are located, although only rarely apparent. Posteriorly, there appear two lateral grooves and a central one, which would originate in a circular depression on the level of leg IV and which are described in Fig.
