sp. nov.
(
Figs. 1
A, 3C–D, 5, 6A, 7, 9, 11, 12)
Diagnosis.
Recognized by its relatively large size; more or less mottled dorsum; basic coloration dark brown to blackish brown (
Figs. 3
C, D). Male genitalia as in
Figs. 7
,
9
; lobal sclerite with prominent, triangular spines (
Fig. 11
). Sclerotized ring elongate and thin, adjoining with SPGC laterally (
Fig. 12
). Most similar in general appearance to
P. izanagii
Yasunaga & Schwartz, 2015
, which is currently known only from
Japan
and assumed to be the closest sister taxon;
P. goryeonus
sp. nov.
can be distinguish by darkened apex of antennal segment II, unclear annulation of metatibia, thicker sensory lobe of left paramere and longer right paramere, smaller and sharply notched combshaped lobal sclerite.
