Pipistrellus javanicus Javan Pipistrelle Scotophilus javanicus Gray, 1838: 498; Java Pipistrellus peguensis Sinha, 1969: 83; Pegu, Burma New material from Myanmar Bago Division: Bago township, August, 2002, 10 ♂♂ (B50–51, 55–56, 84, 91, 110, 120–121, W1-2); Yangon Division: Thone Kwa, -.10.2003, 2 ♂♂ (TK1, TK2); Mon State: Kyaik-Kha-Mi, 13.03.2001, 1 ♂ (K24). Previous records from Myanmar Kachin State: Dalu (Carter, 1943); Rakhine State: Bout-thi-su Quarter [Sittway] (Pearch et al., 2003); Bago Division: Bago (= Pegu, type locality of peguensis, Sinha, 1969); Tanintharyi Division: Myeik ([Mer- gui] = P. coromandra in Lindsay, 1926 but subsequently referred to P. peguensis by Sinha, 1994). Descriptive characters A medium-sized pipistrelle with a fore- arm length of 29.3–32.0 mm based on 13 specimens from Myanmar (Table 4; FA = 30.0–36.0 mm in Bates and Harrison, 1997 and 32.3–36.2 mm in Hendrichsen et al., 2001). The pelage is unremarkable, rang- ing from chestnut to darker brown, with a frosting of some paler brown hairs on the back. It is buffy brown on the ventral surface but with the hair roots almost black. The fifth metacarpal is about equal in length to the third and fourth. The baculum, which measures 5.1–5.8 mm has a bilobate base, a thin shaft and a bifid tip (Fig. 2B). The skull, with a condylo-canine length of 11.6–12.3 mm is relatively large for Pipistrellus. The zygomata are thin and without processes. The second upper incisor (I3) is about equal to the first (I2) in crown area and attains the height of the secondary cusp. The upper canine (C1) usually has a secondary cusp. The first upper premolar (P2) is about equal in crown area to I2 and is intruded from the toothrow. The second lower premolar (P4) slightly exceeds the first (P2) in crown area and is about two- thirds the height. Similar species The penis, with a length in excess of 6 mm, and the baculum of P. javanicus ex- ceed in length those of all other local pip- istrelles except P. paterculus and P. abra- mus, which are significantly ...
