Minervarya asmati is a frog through the genus Minervarya in the subfamily Dicroglossinae of the family Dicroglossidae . He was from specimens from the campus of until 2011 University of Chittagong described and in Bangladesh widespread.
description
Minervarya asmati is a medium-sized frog with a slender and somewhat elongated body and a head-to-trunk length of 29.1 to 33.4 millimeters in male frogs. The basic color of the back varies in the living animal from olive green to greenish brown, on it there are irregular dark spots that connect to each other to form horizontal stripes. Most animals have a narrow, light stripe running from the neck to the base of the tail. There are two red dots on this dorsal midline and on both arms. The flanks are marbled. There are dark spots on the thighs, the lower legs and arms are striated across. The belly is creamy white and has no markings. In the case of formalin preparations, the olive green base color changes to a whitish brown, the red points disappear and the drawings become paler. The head is large, triangular and slightly longer than it is wide. The nostrils are much closer to the tip of the snout than to the eyes. The fingers are slender and there are no webs between them. There are only incompletely formed webs on the toes. The finger formula is 2 <4 <1 <3 and the toe formula 1 <2 <5 <3 <4.
distribution
The type locality is before the Teachers Club and Guest House on the campus of the University of Chittagong ( 22 ° 28 '0 " N , 91 ° 47' 0" O ) in the Upazila Hathazari, near the city of Chittagong . There the species was found in pools near a stream. Later finds from other parts of the country, the northwest and the area around the capital Dhaka , suggest a widespread use, at least in Bangladesh.
Way of life
Minervarya asmati is nocturnal and lives on the edges of forests on moist and shady soils, on moist meadows with loose soil, but also in fields. It feeds on small insects . The breeding season begins in May and lasts until July. At the locality of the type, the species lives sympatric with several other species of the genus Minervarya , but is not found with them during the mating season. A species of the genus Microhyla , however, also occurs in the same spawning water during the mating season.
Hazard and protection
The World Conservation Union IUCN has Minervarya asmati recorded in 2015 in its Red List of Fauna of Bangladesh, but because of the large distribution area and the presumably large number of individuals designated as uncritical (Category LC - Least Concern ). At the time of its inclusion in the Red List, Minervarya asmati was still seen as a possible endemic to Bangladesh, the actual size of the distribution area was only known later.
Systematics
Minervarya asmati is one of about forty species of the genus Minervarya that are distributed in South Asia and play the role of the Southeast Asian genus Fejervarya . Minervarya and about a dozen other genera and about 200 species form the subfamily dicroglossidae, in turn comprising the two genera and 16 species subfamily Occydozyginae the family dicroglossidae forms.
Initial description
The first description of Fejervarya asmati was made in 2011 by the Bangladeshi herpetologists Mohammad Sajid Ali Howlader from the University of Chittagong . The holotype is a male captured at the type site in May 2008, which is in the collection of the Zoological Institute of the University of Chittagong with four adult male and one adult female paratopotype. Howlader honored his teacher and mentor Ghazi SM Asmat with the species name asmati , in recognition of the support he had given to his research.
Synonyms

- Zakerana asmati ( Howlader , 2011)
In the year of the first description, Howlader placed the species in the genus Zakerana Howlader , which he newly established in 2011. This genus was synonymous with Fejervarya in 2015 . In 2018 the South Asian species of Fejervarya were spun off again as a separate genus Minervarya .
