Murina peninsularis

French: Murine péninsulaire / German: Niederkalifornien-Réhrennase / Spanish: Ratonero narizudo peninsular

Taxonomy. Murina cyclotis peninsularis Hill, 1964,

Ulu Chemperoh, near Janda Baik, Bentong District, Pahang, Malaysia.

See M. fionae . Murina peninsularis was recently elevated to a distinct species based on genetic and morphological data. It might represent multiple species, with a second species in Borneo that is highly divergent from other populations of M. peninsularis . Monotypic.

Distribution. Malay Peninsula, S Sumatra (Lampung), Borneo, and Lombok.

Descriptive notes. Head—body 39- 9-42 mm,tail 32- 4—46 mm,ear 11-9-18- 8 mm, hindfoot 5-6- 10 mm, forearm 33-8-39- 4 mm; weight 5-5-11- 9 g. Males average smaller than females. Fur silky. Dorsal pelage is orangish brown (hairs with buff bases and coppery brown to orange-brown tips), with longer guard hairs scattered throughout; venter is paler and grayer (hairs with pale buff bases and grayish brown or white tips), being more orangish near chin and on side of abdomen. Dorsal pelage extends sparsely onto wings, uropatagium, thumbs, and feet. Face is sparsely haired except for long protuberant naked nostrils. Ears are short, broad, and rounded, with smoothly convex anterior margins, no notch on posterior margins, and broadly rounded tips; tragusis long and narrow and tapers toward pointed tip. Wing attaches near base of claw on first toe. Baculum is almost oval and short (1-8 mm long), with rounded or very slightly concave anterior margin, pointed posterior margin, upwardly arched dorsal side, and deeply concave ventral side. Skull is robust and relatively large, with slightly to highly domed braincase and short, bulbous rostrum;sagittal crest is well developed; I” islateral to I’; C! is massive, exceeding P* in height and crown area; P* is subequal to P* in height and is two-thirds the crown area; M' and M?® are lacking mesostyle, and labial surfaces have deep V-shaped indentation; and trigonids of M| and M, are ¢.50% the size of their respective trigonids.

Habitat. Primary and secondary evergreen forests (Thailand) and lowland to hill and montane forests (Malaysia).

Food and Feeding. No information.

Breeding. A pregnant Peninsular Tube-nosed Bat with two embryos, one in each uterine horn, was collected in February in Malaysia.

Activity patterns. Call shape of the Peninsular Tube-nosed Bat is steep FM sweep, with average start frequency of 163-3 kHz (139-183 kHz), end frequency of 50-2 kHz (40- 64 kHz), and peak frequency of 112-7 kHz (79-143-6 kHz) in Thailand.

Movements, Home range and Social organization. No information.

Status and Conservation. Not assessed on The [UCN Red List. Virtually nothing is known about ecology of the Peninsular Tube-nosed Bat, and additional research is needed to clarify its conservation status.
