Macroglossus minimus (E. Geoffroy 1810)

Dagger-toothed Long-nosed Fruit Bat (Cecadu Madu Bakau)

Specimens examined (11).—Monggis: TTU 108225 (GenBank EU521602 ), TTU 108226, TK 152070, TK 152071, TTU 108227, TTU 108231, TTU 108232; Mt. Penrisen:TTU 108350, TTU 108366, TTU 108374, TTU 108376.

Type locality.— Indonesia, Java .

Malaysian distribution.—Recorded from both Peninsular Malaysia (all states) and Borneo.

Remarks.— Macroglossus minimus and M. sobrinus were netted near banana trees and in most cases they were caught alongside C. brachyotis . Macroglossus minimus can be morphologically distinguished from M. sobrinus by the absence of a median groove in the upper lip, and its smaller FA length (FA <42 mm vs. FA> 42 mm; Payne et al. 1985; Francis 2008). Recent literature and SAMD database indicate M. minimus occurs throughout Southeast Asia, whereas M. sobrinus is restricted to Peninsular Malaysia, Sumatera, and Java. Low cyt- b genetic distance (1%) was observed within Bornean populations of M. minimus . A specimen, TTU 108366 (male), from Mt. Penrisen, Borneo, was identified as M. minimus based on the absence of a median groove in the upper lip and FA = 42 mm. This individual is genetically closer to M. sobrinus rather than M. minimus . Genetic distance between M. minimus (Borneo) and M. sobrinus (Peninsular Malaysia) averaged 2% and was the lowest for any sister species relationship within our data for the family Pteropodidae from Malaysia. Although they may represent two species, a genetic distance value of 2% is typical for conspecific bat populations (Bradley and Baker 2001; Baker and Bradley 2006) and we question the recognition of these geographically isolated populations as distinct species. Three of our five female specimens were pregnant; TK 152070 (7 August 2006), TTU 108231 (7 August 2006), and TTU 108350 (17 August 2006).
