New material

Three individuals were collected as voucher specimens. Lampung Province: Sumber Rejo Village, 2♂♂ (MZB 34970, 34990), Sukabanjar Village, 1♀ (MZB 35045).

Remarks

This is a small Myotis  species (FA = 31.4–34.7 mm) with the wing membrane attached at the base of the toes. The fur is dark brown to black on the upperparts and grayish brown on the underparts. Some individuals have slightly shiny-tipped fur on the upperparts. The skull is generally flat and the second upper premolar is intruded from the toothrow. In comparison to all known Myotis  species of the Sunda Shelf, it is similar to Myotis ater  in its cranial and dental characters, but differs in the range of forearm length (FA is 34.0–39.0 mm in M. ater  — Kingston et al., 2006). The body size and dental characters are similar to M. siligorensis  ( Yasuma et al., 2003; Kingston et al., 2006) but cranial characters differ (SW, unpublished data). Neither M. ater  nor Myotis siligorensis  have been recorded on the Sumatran main island although there is a record of M. ater  from an offshore island in West Sumatra ( Simmons, 2005). Further comparison and molecular analyses are necessary to clarify the taxonomic status of this species. In the study area, it was distinguished from other Myotis  species, except M. muricola  , by its smaller forearm length. It is indistinguishable from M. muricola  externally, but can be differentiated by the tooth arrangement: the second upper premolar (P 3) is in line with the toothrow in M. muricola  and displaced inwards such that the adjacent premolars are in contact or nearly so in Myotis  sp. 1 ( Corbet and Hill, 1992). Individuals were caught with both harp traps and mist nets at ground level in coffee plantations, and sometimes trapped with M. muricola  .
