MESOCYCLOPS, SARS, 1914
First antenna with 17 segments reaching beyond the
cephalothorax. Last segment of fifth leg of female
with 2 long setae. Inner setae on caudal branch more
than twice as long as outer setae. Last segment of
fifth leg of female with one terminal seta and one
seta on the inner margin. First antenna with hyaline
plate on last segment. Planktonic. Copepodits feeds
mainly on zooplankton (calanoids, cladocerans and
rotifers) and phytoplankton, when the phytoplankton
is abundant. Some species are known as predators on
smaller freshwater animals, such as mosquito larvae,
cladocerans, rotifers and other copepods.
See Ueda & Reid (2003a) for at comprehensive key of
the genus.
The following key is a combination of records from
the Philippines and records from South-East Asia
outside Philippines. Of the 4 Philippine records of
Mesocyclops species (M. leuckarti, M. aspericornis,
M. microlasius, and M. ogunnus) the records of M.
leuckarti has to be revised. The species is now
confined to the Palaearctic area and records from
the tropics are no longer valid. It is the hope
that the expanded key, with some selected candidate
species, can help in identification of "M. leuckarti"
[1928a, 1930a,1941,1978a+b]. See Ueda and Reid's
(2003a) key for Mesocyclops of the world.
