Macrobiotus pustulatus Ramazzotti, 1959

( Figs. 5–8 ; Table 1 )

The peribuccal lamellae were not cited in the original description of the species ( Ramazzotti 1959). The two types examined are not well preserved and it is not possible to determine the presence either of peribuccal lamellae or papulae. The characters 1, 2, 3, 9 and 10 were visible in both specimens. In the holotype (ventral position), the stylet support insertion point has a pt = 65.5 (character 5), the ventral lamina a pt = 51.7 (character 6) and the macroplacoid row a pt = 34.5 (character 7).

The species has large claws with very evident accessory points in the main branch ( Fig. 6 ). The presence or absence of granulation on the legs is not detectable.
