Freshwater Hemiptera commonly known as aquatic bugs
are widely distributed in the aquatic ecosystem. There are 325 species belonging to 84 genera
and 18 families reported from India (Basu &
Subramanian 2017). The aquatic bug
belongs to the suborder Heteroptera (true bugs), in
which infra order Gerromorpha are semi-aquatic bugs
living on the surface water. Gerromorpha include eight families, viz.: Gerridae, Veliidae, Hydrometridae, Hebridae, Hermatobatidae, Paraphrynoveliidae,
Macroveliidae, and Mesoveliidae
(Damgaard 2008).
Family Gerridae has 26 genera and 93 species
in India (Basu & Subramanian 2017), in which
genus Ptilomera are large water striders
distributed in the aquatic habitats.
Globally, there are 57 species belonging to the genus Ptilomera, in which only six species were documented
from India (Jehamalar et al. 2017): Ptilomera agriodes Schmidt,
1926; P. assamensis Hungerford & Matsuda,
1965; P. laticaudata (Hardwicke, 1823); P. occidentalis
Zettel, 2003; P. tigrina
Uhler, 1860, and
P. nagalanda Jehamalar
& Chandra, 2017.
Among this P. agriodes
was originally described from Tiruchirappalli and Tharangambadi,
in the state of Tamil Nadu. Later it was
reported from Chhattisgarh, Jharkhand, Karnataka, Kerala, Madhya Pradesh, Maharastra, Odisha, and Rajasthan by various workers (Thirumalai 2002; Thirumalai et
al. 2007; Jehamalar & Chandra 2013; Basu et al. 2015; Jehamalar
et al. (2017). Earlier, Basu et al. (2015) reported P. agriodes
only from Devkund waterfall, Mayurbhanj District,
Odisha region of Eastern Ghats. The
present study documents P. agriodes extended
distribution from different parts of Eastern Ghats regions like Andhra
Pradesh, Odisha, Telangana and Tamil Nadu.
P. agriodes was collected from the different streams of Eastern
Ghats (Table 1, Figure 1). The specimens
were collected by hand-operated insect-nets and preserved in 10% formalin and labeled. After
sorting, the specimens were observed under stereo zoom microscope (Olympus
SZX10). The specimens are deposited at
the National Zoological Collection, FBRC/ZSI, Hyderabad.

Diagnostic features:
Body length of the male is 13–14
mm; Female 11–12 mm. Surface of the body
is dark brown to yellow brown in color. Eyes are large reddish-brown to black and
broadly rounded. First antennal segment
is larger than combining length 2–4.
Rostrum is short, male mid femur fringe of black setae. Length of male
abdomen 6mm, paramere curved and contains setae. Hind legs are longer than body length;
spine-like lateral process of the pygophore extended
well the lateral process of the proctiger. The posteromedian margin of the proctiger is bisinuate.
