Genus Hesperoptenus

Peters, 1869

False Serotine bats

This genus is externally similar to Eptesicus (Ese4). However the skull differs on account of its relatively broader palate with a wide anterior emargination; in the presence of well developed basioccipital pits and in the structure of the upper incisors (Hill, 1976a). The first incisor (I2) is large, the area of its base more than half that of the canine; the second (I3) is short, forced backward from the toothrow and quite invisible from the front. M3 has less than half the crown area of M1, but with the metacone and three commissures distinct though small (Fig. 239).

Dental formula:   i - 2 3   c 1   pm - - - 4   m 1 2 3 = 32.
                          1 2 3      1       - 2 - 4       1 2 3

The genus includes five species with geographical range that extends from India to Thailand, Malaysia, Indonesia and south-west China (Koopman, 1993). One species is present in the Indian Subcontinent:
Hesperoptenus tickelli
