Sadu Chiru Waterfall:
The waterfall is located at a distance of about 25 km from the capital city Imphal, Manipur. The waterfall is known as Sadu Chiru Falls or Leimaram Waterfall. The waterfall is located within a forested section at the base of the mountain. The forest is of subtropical evergreen forest.

Field Trip:
December 2015:
The first trip to Sadu Chiru falls was conducted during December 2015 for a day. I and Mr Baleshwor Soibam were present on the trip. The observation started at around 9 am in the morning and lasted till evening at 4 pm. During this period we have observed many species of butterflies flying in and around the falls. We also observed a group of Pieris melete montana puddle on the mud along with Appias lalage and some unknown Hesperids near the stream. On this day we have recorded about 27 species of butterflies. We have observed only 1 species of Swallowtail butterfly i.e. Papilio polytes. Most common to this time of the year was Pieridae butterflies.

April 2017:
The second trip to Sadu Chiru falls was conducted during April 2017 for a day. Mr Harmenn Huidrom, Dr Zdenek Flatynek Fric and I conducted the observation of butterflies around the falls. Most active were the swallowtail butterflies, we have observed about six species of swallowtails Papilio polytes, Papilio helenus, Papilio memnon, Papilio paris, Atrophaneura varuna, Atrophaneura dasarada, etc. Most of the butterflies were seen flying in the shades of the canopy.

A complete checklist on the butterflies collected from Sadu Chiru falls are prepared based on this two trips. The checklist consist of 64 butterflies representing 6 families; Hesperiidae (9 sp.), Lycaenidae (10 sp.), Riodinidae (2 sp.), Pieridae (7 sp.), Papilionidae (10 sp.) and Nymphalidae (25 sp.).

..........................................................

During the fieldwork in 2016 for my PhD studies on the composition of moths at different altitudes of Shirui Hills, Manipur, collected many species of moths belongs to different families. One of the family was Notodontidae.

Notodontidae is a family of moths with approximately 3,800 known species. Moths of this family are found in all parts of the world, but they are most concentrated in tropical areas. The members of this family tend to have heavy-bodied and long-winged, the wings held folded across the back of the body at rest. They rarely display any bright colours, usually being mainly grey or brown. These features mean they rather resemble Noctuidae although the families are not closely related. The adults do not feed. Many species have a tuft of hair on the trailing edge of the forewing which protrudes upwards at rest. This gives them their scientific name "back tooth" and the common name of prominents. The common names of some other species reflect their hairiness, such as puss moth and the group commonly known as kittens (Furcula spp.), so named as they resemble small versions of the puss moth (Wikipedia).

Among, 12 species of Notodontidae, I came across a species from the genus Euhampsonia, which was quite different from other Euhampsonia species found in India and other parts of the world. I tried to find out the exact identity of the species by referring to many publications, literature and books including Notodontidae of Palaearctic region but I could not found a match. Later I decided to study the genitalia and compare with other Euhampsonia sp. There also I could not found any success. Later, I send the photograph of the adult along with its genitalia photo to Dr. Alexander Schintlmeister who is an expert on the Notodontidae fauna of the world.

After a few days back I got a reply from him, saying that the photograph belongs to an undescribed species of Genus Euhampsonia. He also has few materials from the neighbouring country Myanmar and he suggested me to describe it together.

Now the species is described as Euhampsonia rubricata (Schintlmeister & Irungbam, 2018), a new member of Genus Euhampsonia and is accepted for publication at ZOOTAXA.
The genus Euhampsonia includes the following taxa:

Euhampsonia Dyar, 1897
