Diagnosis
Monepidosis scepteroides
sp. nov.
is the only
Monepidosis
with only one pair of parameral tusks (↓,
Fig. 11C
). Of the gonocoxites (
Fig. 11A
), the wide, shallow ventral emargination has a glabrous rim basally (↓); the central processes, which are situated posterior to that rim, form a widely open, unevenly sclerotized V-shape (↓); and gonocoxal processes are missing.
Differential diagnosis
Monepidosis scepteroides
sp. nov.
is similar to
M. scepteri
Spungis, 2006
, especially with respect to the central processes. In
M. scepteroides
sp. nov.
, as distinct from
M. scepteri
, the gonocoxites are wider than long instead of the reverse, and the plate-like gonostylar spine is a single piece rather than consisting of two clearly separated portions (
Spungis 2006
: fig. 4B). Like all
Monepidosis
but
M. scepteroides
sp. nov.
,
M. scepteri
has two pairs of parameral tusks (
Spungis 2006
: fig. 4A).
Etymology
The name
scepteroides
, an adjective, refers to the similarity of this species to
M. scepteri
.
