Type locality
. Baoshan Pref., Gaoligong Shan, Yunnan, China.
Etymology.
This species is names after Michael Schülke the collector of the
type
series.
Distribution.
China
,
Yunnan
.
Diagnosis.
The external morphology of this species is most similar to
P. javanus
and
P. pseudojavanus
, but it can be easily distinguished from both of these species by the black coloration and simple, apically rounded shape of aedeagal parameres. In addition,
P. javanus
and
P. pseudojavanus
are known from
Java
and
P. schuelkei
is distributed in southern
China
.
Description
.
Body.
Body black, length
6.5–6.8 mm
. Elytra uniformly colored.
Head.
Clypeus with two distinctly produced teeth, their outer margin not notched basally.
Pronotum.
Pronotum rounded laterally. Frontal angles rounded. Disc covered with punctures separated by 0.5– 2.0 puncture diameter(s). Pronotum in anterior-posterior direction notably shorter than elytra.
Elytra.
Elytra covered with sparse punctures.
Wings.
Wings normally developed.

Legs.
Profemur with almost straight or sinuate anterior margin. Protibia with apical spur approximately reaching middle of protarsomere 3. First tooth almost not modified in males, approximately as wide as second tooth; first and second teeth distinctly separated from each other; first tooth normal, distinctly separated from denticles located between first and second teeth. Metafemoral posterior margin not serrate, simple, not modified. Metatibia slightly sinuate, inner margin not denticulate, straight, not produced apically.
Metasternum.
Transverse basal ridge of metasternum long, at least 1/5 of mesocoxa length.
Aedeagus.
Parameres symmetrical, simple, apex widely rounded and inferiorly angulate.
