Fierce Leaf-nosed Bat

Hipposideros dinops

French: Phyllorhine féroce / German: Salomonen-Rundblattnase / Spanish: Hiposidérido de Andersen

Other common names: Fierce Roundleaf Bat, Giant Horseshoe Bat

Taxonomy. Hipposiderus [sic] dinops K Andersen, 1905 ,

“Rubiana [= Roviana Lagoon], a minute inlet very near western coast of New Georgia, Solomon Islands.”

Hipposideros dinops is in the diadema species group. Many authors have considered this species to include pelingensis as a subspecies, but these taxa are separated by 1800 km and are diagnosably different. Here H. pelingensis is considered a good species, following N. B. Simmons in 2005.

Monotypic.

Distribution. Solomon Is (Bougainville, New Georgia, Santa Isabel, SanJorge, Malaita, and Guadalcanal).

Descriptive notes. Head-body 88-105 mm, tail 54-63 mm, ear 31-35 mm, forearm 86*1-98* 9 mm; weight 78 g. Ears of the Fierce Leaf-nosed Bat are large, triangular, and slightly concave below tips. Noseleaf is well developed and has three supplementary lateral leaflets, of which the third is the smallest. Anterior leaf is large and has no central emargination. Intermediate leaf is expanded and presents a protuberance in middle. Upper border of posterior leafis semicircular with a small projection, and has medial septum and two lateral septa forming four cells. Males present a frontal sac. Fur is whitish or white with light brown spots on dorsum, while ventral fur is yellowishbrownish.

Habitat. The Fierce Leaf-nosed Bat has been observed over forest habitats and tropical moist lowland. It has been reported from sea level up to 400 m.

Food and Feeding. The Fierce Leaf-nosed Bat is probably insectivorous.

Breeding. No information.

Activity patterns. The Fierce Leaf-nosed Bat occupies caves. Its CF echolocation call frequency ranges at 52-55 kHz.

Movements, Home range and Social organization. The Fierce Leaf-nosed Bat has been observed roosting both alone and in small groups of up to twelve individuals.

Status and Conservation. Classified as Data Deficient on The IUCNRed List, due to the lack of information on its population status. The Fierce Leaf-nosed Bat occurs at low densities and it has only been reported from a few localities. The overall population is thought to be decreasing. Further research on ecology and threats is needed in order to establish adequate conservation measures.
