Rosevear's serotine (Pseudoromicia roseveari) is a species of vesper bat that lives in Guinea and Liberia. It was described as a new species in 2013. It is listed as endangered by the IUCN.

Taxonomy and etymology

It was described in 2013. Its closest relative is the dark-brown serotine, Pseudoromicia brunnea. Rosevear's serotine and the dark-brown serotine are separated by a genetic distance of 6.97.2%. The new species was assigned to the genus Neoromicia based on its single upper premolar: a trait shared amongst all species in the genus. The authors who described the species chose the specific epithet "roseveari" to honor Donovan Reginald Rosevear, "who made a significant contribution to West African bat research in the 20th century, culminating in his book The Bats of West Africa". [2]

Although initially described in the genus Neoromicia, a 2020 study found it to belong to a separate genus, described as Pseudoromicia . [3]

Description

It is a small bat, with a total body length of 89–91 mm (3.5–3.6 in). Its tail is 39–44 mm (1.5–1.7 in); its forearm is 37 mm (1.5 in) long; its hindfoot is 8 mm (0.31 in) long; its ear length is 13–14 mm (0.51–0.55 in). It has a body mass of 6–6.3 g (0.21–0.22 oz). Its maximum skull length is 14.36–14.47 mm (0.565–0.570 in). Despite this small size, it is the largest "pipistrelloid" (bats in the genera Afronycteris , Pseudoromicia , Laephotis , Hypsugo , Neoromicia , and Pipistrellus ) in West Africa. In some aspects, Eisentraut's serotine overlaps with Rosevear's serotine in size, though they can be differentiated by their morphology. Its fur is dark chocolate brown in color. The fur on its ventral surface is bicolored, with the bases of individual hairs darker than their tips. The fur on its dorsal surface is a constant color throughout, in contrast to the bicolored ventral fur. Its ear is relatively short, and rounded at the tip. The outer edge of the tragus is curved; the base of the tragus has a "distinct lobe." Relative to other species in its genus, it has a robust skull and a broad snout. Its dental formula, typical for Pseudoromicia species, is 2.1.1.23.1.3.3, for a total of 32 teeth. [2]

Biology

As only six individuals have ever been encountered, [1] very little is known about the biology of this species. A female captured in Guinea in early March 2008 was pregnant, however, with a fetus 20 mm (0.79 in) from crown to rump. [4]

Range and habitat

Only six specimens have ever been documented. Four specimens were recorded on the Liberian border of Mount Nimba and the other two specimens were in the Simandou Range of Guinea. All captured individuals were netted over small streams in primary rainforest. Two of the Mount Nimba individuals were encountered at 450–550 m (1,480–1,800 ft) above sea level. [1]

Conservation

It is currently evaluated as endangered by the IUCN. Major threats to this species include deforestation via slash-and-burn agriculture, logging, and mining. [1]

Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is frequently observed or the subject of research. The facial features of the species are often simple, as they mainly rely on vocally emitted echolocation. The tails of the species are enclosed by the lower flight membranes between the legs. Over 300 species are distributed all over the world, on every continent except Antarctica. It owes its name to the genus Vespertilio, which takes its name from a word for bat, vespertilio, derived from the Latin term vesper meaning 'evening'; they are termed "evening bats" and were once referred to as "evening birds".

Pipistrellus raceyi, also known as Racey's pipistrelle, is a bat from Madagascar, in the genus Pipistrellus. Although unidentified species of Pipistrellus had been previously reported from Madagascar since the 1990s, P. raceyi was not formally named until 2006. It is apparently most closely related to the Asian species P. endoi, P. paterculus, and P. abramus, and its ancestors probably reached Madagascar from Asia. P. raceyi has been recorded at four sites, two in the eastern and two in the western lowlands. In the east, it is found in open areas and has been found roosting in a building; in the west it occurs in dry forest. Because of uncertainties about its ecology, it is listed as "Data Deficient" on the IUCN Red List.

The Isalo serotine is a vesper bat of Madagascar in the genus Laephotis.

After the first specimen was caught in 1967, it was described as a subspecies of Eptesicus somalicus in 1995. After four more specimens were collected in 2002 and 2003, it was recognized as a separate species. Because of its small distribution and the threat of habitat destruction, it is considered "vulnerable" in the IUCN Red List.
