Identification. This microhylid was diagnosed as typical of the M. ornata complex with a triangular body, no visible tympanum, tan dorsum with dark X-shaped mark, and a dark lateral line ( Kabir et al. 2009). Calls were a short, high-pitched “screech.” Our specimens agreed with the morphological characteristics for M. mymensinghensis described in Hasan M et al. (2014) and Poyarkov et al. (2014) in that they had a distinct outer tarsal tubercle and relatively long hind limbs (tibio-tarsal articulation varied from the eye to between the eye and snout). However, their large SVL (19.2–22.2 mm in males, 23.0– 24.1 mm in females) was above the range described by Hasan (14.2–17.6 mm in males and 15.2– 21.3 mm in females).

Taxonomic notes. Hasan M et al. (2014) demonstrated with mitochondrial DNA that frogs from this complex in central and northeast Bangladesh are M. mymensinghensis . Garg et al. (2019) reported from more extensive ge- netic testing that the range of M. mymensinghensis fully envelops our study site with no other species in close proximity, and in their examination of field specimens they also found that morphological characteristics overlap between species and are inconsistent with the descriptions in Hasan M et al. (2014).

Habitat. Microhyla mymensinghensis was widespread in the park, found in all habitats. It appeared on the surface less often than M. berdmorei and could instead be uncovered by raking leaf litter.

Remarks. JH observed 7–10 of these frogs calling around a rain puddle in mature forest on 28 Jun. 2015. JH observed numerous males making an impressive din around a flooded fallow paddy field after a storm on 8 July 2015.
