· Inner portion of basipodite of 1st leg without seta
· With patterns of hair on 5th segment.
· Caudal rami without hairs (Alekseev, 2002a).
137 a. Maxillulary palp with group of spines. Can be used
as a biological control agent of Aedes aegypti
(Linnaeus) (Panogadia-Reyes et al., 2004a).
Found in all types of water bodies: fishponds,
rice fields, lakes and reservoirs, eutrophic ponds
with heavy micro algae, marshes, and brackish and
saline waters. Not found in limnetic habitats
(Papa and Hołyńska 2013). Common.
- Philippines.

138 b. Genital double segment with small hairs on anterior part
of dorsal surface (pilose). Maxillulary palp without group of
spines. Body length 800-1200 μm. Caudal rami without hairs.
5th segment with hairs. It feeds on brachionids and other
rotifers, and prefers Brachionus calyciflorus for B. angularis
(Kumar and Rao, 2001.)
In ponds, rainwater tanks, and pelagic zone and among plants
of large lakes.
Probably very common. Papa and Hołyńska (2013) claimed that
this species formerly might have been determined as M. leuckarti
(see 133a), e.g. in Laguna de Bay and Lake Naujan.

Mesocyclops thermocyclopoides, HARADA, 1931
[1981c, 2002a, 20032, 2012a, 2013].
139 a. Transverse ducts of genital double segment directed towards
each other at straight angle before connecting with copulatory
duct. Small spines present at implantation of lateralmost
terminal caudal seta. Maxillulary palp without group of spines.
Genital double segment bare on dorsal surface. Body length
900-1600 μm. Found in shallow ditches, rainwater tanks, jars,
swamps, lakeshores, ponds, rice fields, and in plankton in
deep lakes.
- Not recorded from the Philippines.
Distributed in New Guinea through Indonesia and Malaysia
as far as Indochina.
Mesocyclops affinis VAN DE VALDE, 1987
[2003a].
Following species is placed in the Pseudospinolosus group by
Fernando (2002a). Since it, according to Ueda & Reid (2003a),
doesn't posses these, it is here placed in the
Thermocyclopides group.
139 b. Transverse ducts of genital double segment directed towards
each other at acute angle before connecting with copulatory duct.
Small spines present at implantation of lateralmost terminal
caudal seta. Maxillulary palp without group of spines.
Genital double segment bare on dorsal surface. Body length
1000-1300 μm. Littoral zone of lakes, ponds, rice fields,
streams, ditches, water containers, wells, and also found
in coral gravel pits.
– Not recorded from the Philippines. Distributed in
Australia, New Guinea, Indochina, South China,
and Japan.
