Differential diagnosis
The male palp is similar to that of
P. spiniger
sp. nov.
in having a sinusoid anterior lobe of the bulb, but may be recognized by the strongly sclerotized keel on the prolateral edge of this lobe and the absence of a spine at the base (compare
Fig. 1A–C
with
Fig. 13A–C
). The female slightly resembles those of
P. securis
sp. nov.
and
P. spiniger
sp. nov.
They share an epigyne in which the distance between the lateral edges of the atria is smaller than the distance between the lateral edges of the spermathecae. However,
P. lamottei
sp. nov.
may be distinguished by the atria, which are cup-shaped (narrower in the other species, compare
Fig. 2A–C
with
Figs. 12A–B
and
15A–C
).
Pochytoides lamottei
sp. nov.
also differs from
P. spiniger
sp. nov.
by the presence of epigynal pockets and from
P. securis
sp. nov.
by clearly shorter seminal ducts.
