French: Crocidure de Panay / German: Panay-WeiRzahnspitzmaus / Spanish: Musarana de Panay
Other common names: Panay Shrew
Taxonomy. Crocidura panayensis Hutterer, 2007 ,
“The Philippines, Panay, NW peninsula , Sibaliw , Municipality of Buruanga [11° 49-188’ N, 121° 58-064’ E], 450 m.” GoogleMaps
Previously assigned to C. palawanensis by R. Hutterer in 2002. Specimens have been studied in more detail and are now separated as C. panayensis . According to genetic studies done byJ. A. Esselstyn and colleagues in 2009 and 2010,this speciesis related to C. negrina , C. ninoyi, and C. min-
dorus within a central Philippine clade. Monotypic.
Distribution. Known only from NW peninsula and SW Panay I, Philippines. View Figure
Descriptive notes. Head-body 65-74 mm, tail 58-64 mm, hindfoot 14-4-15-4 mm; weight 10-12-5 g. The Panay White-toothed Shrew is a medium-sized shrew, with a long tail (87% of head-body length). It is comparable in size to other Philippine shrews, namely the Mindoro White-toothed Shrew ( C. mindorus ), the Sibuyan Whitetoothed Shrew (C. ninoyi), the Negros White-toothed Shrew ( C. negrina ), the Mount Malindang White-toothed Shrew ( C. grandis ), and the Palawan White-toothed Shrew ( C. palawanensis ). Upperparts are blackish brown, which graduates toward dusky brown on venter. Tail is covered (about 47%) with long bristles on the proximal half, dusky above and slightly paler on underside. Dorsal part of foreand hindfeet are covered by dark hairs, with lateral surfaces slightly darker brown than the inner surfaces; structure of hindfoot (elongate shape, prominent plantar granulae, strong pigmentation) replicates those of most Philippine Crocidura . Skull large and robust, with a long and wide rostrum. The Panay White-toothed Shrew has a very narrow interorbit, and for this reason it was previously assigned to the Palawan White-toothed Shrew, but that species has a longer tail and lower pilosity, and differences in dental traits. Females have two inguinal nipples.
Habitat. Known from the forest floor of primary forest at elevations of 450-480 m in the north-western peninsula of Panay; also present in lightly disturbed forest at elevations of 800-900 m in south-western Panay. Specimens were captured in pitfall buckets put out for frogs.
Food and Feeding. No information.
Breeding. No information.
Activity patterns. Panay White-toothed Shrews are terrestrial.
Movements, Home range and Social organization. No information.
Status and Conservation. Not assessed on The IUCN Red List. Probably widespread in the mountains of Panay, in primary and secondary forest. In south-western Panay, the Panay White-toothed Shrew appearsto be either uncommon to rare or difficult to capture. Panay has undergone extensive deforestation and surveys of additional montane areas are needed.
