In 2009 several specimens of bee shrimp could be collected from two hill streams near the Xingfengjiang Reservoir, Heyuan County, Guangdong Province. According to a local fisherman collecting shrimp for the aquarium trade in this area, the same species can be found in about 20 streams near the Xingfengjiang Reservoir. Specimens from both streams sampled agree well with the original description in both morphology and life coloration of
Caridina meridionalis
Wang, Liang & Li, 2008
(see colour plate 2C for comparison with fig. 8, page
58 in
Wang et al. 2008
).
Wang et al. (2008)
did not mention the branchial formula of their specimens. In the specimens examined the first pereiopods are lacking an arthropod and this species should thus be assigned to
Paracaridina
. Amongst the known members of
Paracaridina
,
C. meridionalis
(based on the bee shrimp herein examined) is very similar to
P. z i j i n i c a
Liang, 2002, also described from Heyuan County, differing only in the length of the stylocerite, which reaches almost to the end of the first antennular peduncle in
P. meridionalis
vs. reaching to the end or slightly overreaching this segment in
P. zijinica
). As this difference is considered to be intraspecific variation,
C. meridionalis
Wang et al. 2008
is here considered to be a junior synonym of
P. z i j i n i c a.
