Macrobiotus
cf.
coronatus
De Barros, 1942
Three adult specimens and one embrionate egg were found. In details of the adult morphology and egg chorion sculpture our material is similar to
Macrobiotus coronatus
, recently redescribed by
Pilato
et al
. (2000)
, with the exception of the following features: no eyes, thinner buccal tube (
pt
value 8.5–10.8), stylet supports inserted on the buccal tube in a slightly more caudal position (
pt
value 75.6–77.5), larger eggs (diameter
73 m
without processes), larger processes (height
10.4–11.1 m
, base diameter
7.4–8.1 m
), very poorly developed reticulation of the processes surface, more evident partition between wide conical basal part of the egg process and the attenuated septate apex, no dots on the shell surface between processes. Our specimens agree basically with the descriptions given by
Horning
et al.
(1978)
and
Nelson
& Horning (1979)
for the specimens from
New Zealand
identified by them as
Macrobiotus harmsworthi coronatus
. This form very likely represents a new species, but additional material needs to be examined in order to ascertain its exact taxonomical status.
