“Gomantong Caves, 5°31°N, 118°04’E,” Sabah, Borneo, Malaysia. GoogleMaps

Subgenus Myotis ; muricola species group. Previously treated within M. ater nugax. Genetic studies place this species as sister to M. annectans ; these two may be most closely related to M. muricola , or to M. pilosus and M. chinensis , and perhaps M. montivagus . Relationship with M. ater and M. munricola 1s unclear; all three occur in Borneo, where respective species limits require further study. Monotypic.

Distribution. N & W Borneo; only known from three localities in Sabah (Gomantong Caves, Baturong Caves, and Sinoa) and recently found in Sarawak (Bukit Sarang, Bintulu division); may be more widespread. View Figure

Descriptive notes. Tail 36-45 mm, ear 12:6—15- 5 mm, hindfoot 8-9 mm, forearm 40- 43 mm; weight 6-4-8- 8 g. Differs from Peters’s Myotis ( M. ater ) in longer forearm and skull; feet small. Dorsal fur has blackish bases and dark brown tips; underparts are dark brownish gray with black hair bases; there is a golden-brown patch in center of belly, as in its sister species, the Hairy-faced Myotis ( M. annectans ). Ears are medium-sized, with anterior margin convex and a rounded tip; tragus is narrow, c.40% ear length, with slightly concave anterior margin and more strongly convex posterior margin, with a marked triangular lobe at its base. Wing membrane is attached at base of toe; calcar is long and narrow toward tip, with a narrow keel. Skull is long and not especially broad, with inflated braincase and shallow frontal depression; no conspicuous sagittal crest. Skull is much narrower and less massive than in the Bornean Whiskered Myotis ( M. browni ). C' is short, roughly equal to or slightly shorter than posterior upper premolar; P? is small, equal to or smaller than I’, and displaced slightly inward; P* is greatly reduced, less than quarter the surface area of P* and displaced inward, so that P* and P* are in contact; C, is small, ¢.20% shorter than P, and ¢.40% smaller than that tooth in surface area; P, is not particularly small, about half the height of canine, and about one-and-a-half times the surface area of I,, completely in line in tooth row; P, is tiny, completely displaced inward so that P, and P, are in contact or nearly so; P, is about the same height as M,. Differs from Peters’s Myotis in greater reduction of middle premolars, and in the small canines which are similar in length to P*, and distinctly shorter than P,. Condylo-basal length 14-3-15- 3 mm; maxillary tooth row 5:6- 6-9 mm.
