The subgenus
Peyerimhoffia
is characterized by a large palpus with few bristles, consisting of just one segment (sometimes with a reduced second segment) without a deepened sensory area and a non-differentiated tibial organ without a semicircular structure. The postpronotum is mostly with a few short bristles. The gonostylus is short and bulbous-oval in shape and has a large tooth with a distinct fissure medially. It is known from the Palaearctic region and only 5 species have so far been described.
Comments
.
Cratyna
(
Pey
.)
vagabunda
was temporarily united with species of the
Corynoptera crassistylata
group in a newly established genus
Peyerimhoffia
based on convergent structures of the gonostylus (
Vilkamaa & Hippa 2005
;
Shi
et al
. 2014
). However,
Cratyna vagabunda
has nothing to do with species of the
Corynoptera crassistylata
group.
Cratyna vagabunda
belongs without doubt to the genus
Cratyna
mainly by having a 1- segmented palpus and a non-differentiated tibial organ. A recent molecular phylogenetic analysis demonstrated that the species
Peyerimhoffia vagabunda
is related to species of
Cratyna
s. str.
and
Spathobdella
(
Shin
et al
. 2013
)
. From the seven species described by Shi
et al
. only
Cratyna hamata
(Shi & Huang)
comb. n.
and
Cratyna obesa
(Shi & Huang)
comb. n.
belong to the subgenus
Peyerimhoffia
. The other five species are newly combined in the genus
Corynoptera
,
crassistylata
group [
C. sparsula
(Shi & Huang)
comb. n.
,

(Shi & Huang)

,
C. yunnana
(Shi & Huang)

C. shennongjiana
(Shi & Huang)
comb. n.
and in
Corynoptera
s. str.
[
Corynoptera longiprojecta
(Shi & Huang)
comb. n.
].
Corynoptera longiprojecta
(Shi & Huang)
is identical in all details with
Corynoptera diversicalcaria
Mohrig, 2004
from Papua New Guinea and a junior synonym to the latter.

*
Peyerimhoffia brachypoda
Shi & Huang (2014)
is spelled
brachypodua
in the Abstract and
brachypoda
throughout the rest of the paper, being alternative original spellings. We hereby acting as the First Reviser, select the spelling
brachypoda
as valid, so that the spelling
brachypodua
is an incorrect original spelling (Art. 24.2.3), (
ICZN 1999
).
