Abstract/ Executive Summary:

A male Bhamo frog Humerana humeralis was first time collected from Rangpur, Bangladesh, outside its usually habitat. The dorsal surface was characteristically olive brown to bright green in colour and the ventral surface was whitish. Black spots were distributed between nostril and between eyes. The length of snout- vent, head, snout were found to be 4 3.25 mm, 14.50 mm and 7.5 mm, respectively. Some information of its natural history is also included in the paper.

Keywords: Humerana humeralis, Distribution, Northwestern Bangladesh

Location: Rangpur city.

Start Date: 00-10-2013

End Date:

Program Area: Variety and Species

Commodity: Frog

Objectives:

To classify and scientific validation of a species in frogs.

Methodology:

Surveys on amphibians were undertaken during evening and night. Observations of the live specimens of this species were made in Rangpur city (25° 44' 19.76"N 89° 15' 13.50"E) during October 2013. Three individuals were observed and only a male specimen was collected on October 14, 2013 at 2100 hours. The specimen was captured using a small net and was preserved in 10% formalin. Specific identity was confirmed based on morpho - meristic data of the live specimen using the key and expanded description provided. The species and the measurements were verified by Dr. Kaushik Deuti, Amphibia Section, Zoological Survey of India, 27 JL Nehru Road, Kolkata 700016, India. Measurements were recorded using a digital slide caliper with an accuracy of 0.2 mm. Measurements were taken in mm. Morphometric characteristics included the following measurements: 1.Snout– vent length (SLV). 2. Head length (HL). 3. Head width (HW). 4. Snout length (SL). 5. Tympanum diameter (TYD). 6. Eye diameter (ED). 7. Distance between Nostrils (DN). 8. Relation of fingers length (RFL). 9. Relations of toe length (RTL).

Achievement/Findings:

The finding of the presence of H.humeralis in eastern Bangladesh. Unfortunately, no morphological description (including measurements such as snout-vent length SVL) has been provided, although size can be a good indicator for classification and scientific validation of a species in frogs.
