Taxonomic Notes
Semnopithecus entellus (Dufresne, 1797) subspecies entellus.
Taxon distribution as listed in assessment
This species occurs in south western Bangladesh and eastern India (in Andhra Pradesh, Bihar, Chattisgarh, Jharkhand, Madhya Pradesh, Maharashtra, Orissa, and West Bengal) and also occurs in Nepal (Chetri et al. 2006). The Bangladesh population is very likely to have originated from a single pair introduced by Hindu pilgrims on the bank of the River Jalangi (Mitra and Molur 2008). This is the only non-human primate species of Bangladesh that does not occur in any of the three forest types the country have. It occurs in south western Bangladesh mainly in Jessore District (Keshabpur and Manirampur upazillas), while few troops have been established in Faridpur, Meherpur, Jhinaidaha and Satkhira Districts.

Assessment rationale/justification
The population of this species is known to have been decreased. Although, Gittins and Akonda (1982) estimated only 100 individuals in Bangladesh. Khan 1987 considered the total population of Hanuman in Bangladesh to be between 250 and 300 individuals considering all ages. Khan and Ahsan (1986) reported 89 individuals in 8 groups in Jessore. Khatun (2012) reported 246 individuals at six villages of Keshabpur under Jessore District. Currently, approximately 204 individuals have been observed in at 11 groups distributed in Keshabpur and Monirampur Upazilas under the same district (Anon 2015, unpublished report), though the total population is not more than 250 individuals occurring in all districts. The number of mature individuals in total population could be slightly more than 140. The Extent of Occurrence of this species is more than 100 km2 but below 5,000 km2. Actual Area of Occupancy is above 10 km2. Since male migration has been occurring, all groups together can be considered as single population.
