Diagnosis.
For males see the diagnosis under
Y. varietas
by
Lee and Kim (2021)
. Males of
Y. lyrica
are also similar to those of
Y. subadulta
(compare Fig.
7 D – F
with
Kim 2021
: fig. 77 E – G) in having a sharp terminal conductor and a sperm duct curving four times, but
Y. lyrica
can be distinguished from
Y. subadulta
in having the conductor extend beyond the cymbium (vs. conductor not exceeding the cymbium in
Y. palmgreni
). Females of
Y. lyrica
are similar to those of
Y. takasukaiYoshida, 2012
(compare Fig.
9 D – F
with
Yoshida 2012
: figs 4, 5) in having a pair of projections on the anterlateral epigynal plate, but
Y. lyrica
can be distinguished from
Y. takasukai
by having oval, laminar projections on the anterlateral epigynal plate and long, curved copulatory ducts (vs nipple-like projections and copulatory ducts short in
Y. takasukai
).

Natural history.
This is one of the most widespread
Yunohamella
species.
This species is found on bushes, forests, and fences, as well as inside houses (
Kaston 1948
;
Levi 1957
;
Gao and Li 2014
;
Kim et al. 2016
;
Lee and Kim 2021
).
Comments.Platnickina mneon
was first described by
Bösenberg and Strand (1906)
based on a female specimen collected in
Saga
,
Japan
. To date, males of
P. mneon
remain unknown.
Dupérré (2023)
provided diagnostic characters and illustrations of
P. mneon
after examining the female
holotype
and noted that this species does not conform to the characteristics of the genus
Platnickina
Koçak & Kemal, 2008
(e. g. copulatory openings located on sclerotized plates in
P. mneon
vs inside the circular depression of the epigyne in
Platnickina
spp.
) and that it likely belongs to another genus. The
holotype
of
P. mneon
exhibits all the diagnostic features of
Y. lyrica
as provided by
Levi (1957)
, including the two sclerotized plates, copulatory openings located on the sclerotized plates, and oval spermathecae (compare Figs
7 D – F
,
9 D – F
with
Dupérré 2023
: fig. 73 B, C and with
Levi 1957
: figs 329, 330). Although the types of
Y. lyrica
and
P. mneon
were unavailable for examination, our comparison based on specimens collected in
Hubei Province
,
China
and the illustrations and descriptions provided by
Levi (1957)
and
Dupérré (2023)
allows us to consider
P. mneon
as a junior synonym of
Y. lyrica
.
