“…The two most similar ecoregions are Cross‐Sanaga‐Bioko and Mount Cameroon Forest (Figure 4a). The 36 species reported in Tanshi et al (2021) represent 30% of the species known from the Lower Guinean Forest (Table S1).…”

“…We recently published data from the first harp trap survey conducted in Nigeria (Tanshi et al, 2021). Specific survey localities were lowland and montane areas of Afi Mountain Wildlife Sanctuary, (hereafter “Afi Mtn WS”) and Cross River National Park (hereafter “Cross River NP”).…”

“…The vegetation has a closed canopy formed by broadleaf evergreen trees, with emergent trees ≥60 m tall in the lowland. Bats were trapped using harp traps and mistnets set for two consecutive nights along existing trails, at 50 m intervals on 200 m transects (see Tanshi et al, 2021 for details). Field trapping spaned the elevational gradient at both survey localities, but only data collected from lowland areas (150–400 m a.s.l.)…”

“…Mist nets underrepresent bat diversity in Paleotropical forests because the dominant insectivorous ensemble of the forest understorey comprises species of the families Rhinolophidae, Hipposideridae, and Nycteridae, and the vespertilionid subfamilies Kerivoulinae and Murininae, all of which are adept at negotiating dense clutter (Kingston et al, 2003; Senawi & Kingston, 2019) and tend to evade capture in mist nets a.k.a. blindspot diversity (Tanshi et al, 2021). This trapping bias presented Findley with low estimates of Afrotropical alpha diversity between 22 and 38 species (Brosset, 1966; Jones, 1971).…”

“…We compare multiple dimensions of bat diversity in Nigeria versus Malaysia, and Indonesia. To measure alpha diversity, we used published data from a multi‐method (ground and canopy‐level mist netting and harp traps) survey (reported in Tanshi et al, 2021) in the largest predicted hotspot of bat diversity in Africa (Herkt et al, 2016) with a focus on two Key Biodiversity Areas (KBAs) of the Lower Guinean Forest of West Africa (hereafter “Lower Guinean Forest”) (Bakarr et al, 2004) in southeastern Nigeria. To compare alpha diversity of Afrotropical bats with the Indo‐Malayan tropics, we compared taxonomic, phylogenetic, and functional diversity from sites that were predicted by Findley to hold vastly different richness in Nigeria (40) to data from Malaysia (80) and Indonesia, Sumatra (80).…”

Bat species commonly comprise at least 50% of tropical mammalian assemblages, but Afrotropical bat faunas have been little studied leading to perceptions that they are depauperate. Here, we compare alpha taxonomic, functional, and phylogenetic diversity of insectivorous bats belonging to the narrow-space foraging ensemble from a bat diversity hotspot in Nigeria to species-rich sites in Indonesia and Malaysia, using previously published data. The Nigerian site is protected unlogged forests at Afi Mountain Wildlife Sanctuary and Cross River National Park. For comparison, we targeted similar

The Cameroon Volcanic Line, which divides the Congo Basin fauna from the West African fauna, is a known area of high endemism for various taxa, but the region's bat fauna has received little attention. We review variation in morphological and molecular (mitochondrial 1 Cytochrome b) characters in the Tropical African vespertilionid bat genus Pseudoromicia.Assessment of this variation indicates the existence of a new species of Pseudoromicia, from the Mbam Minkom Massif in the Centre Region of Cameroon. The new species is diagnosable by sequence data and is morphologically similar to its putative sister taxon, P. kityoi, from Uganda.Although we suggest that it be assigned to the IUCN category of Data Deficient, there should be some concern as to the conservation status of this species: the Mbam Minkom Massif ecosystem is threatened due to lack of legal conservation frameworks and exposure to increasing human pressure. The new species is in a clade with P. roseveari and P. kityoi. These three species may be relicts of a single widespread species originating in the West African "white-winged" group of Pseudoromicia that then spread east across the tropical moist broadleaf forest into East Africa, and are now restricted to a few upland rainforest patches in West Africa (P. roseveari), in outliers of the Cameroon Volcanic Line region (Pseudoromicia sp.), and the Lake Victoria area (P. kityoi). The smaller, white-winged species are hypothesized to be ancestral, with one extant putative species (P. rendalli) also extending into East and southern Africa (Van Cakenberghe & Happold, 2013). The larger, dark-winged taxa likely dispersed to East Africa and subsequently back to West Africa (e.g., Pseudoromicia sp., P. roseveari). Our data illustrate the potential importance of the Dahomey Gap and climatic changes in the evolution of this group of species.

Bangladesh is at the ecological transition between the Indo-Himalayan and Indo-Chinese subregions. The country also has one of the highest human population densities in the world and only 6% remaining natural habitat, putting much of its biodiversity at risk. With more than 1455 species worldwide, bats are an important, but threatened, component of global biodiversity and provide critical ecosystem services. Yet, there is no comprehensive work on species occurrence, diversity, or richness of bats of Bangladesh. Here, we collated data on the bats of Bangladesh and states in neighboring countries from the available literature, the Global Biodiversity Information Facility, and museum databases to assess the probability of occurrence of bat species in Bangladesh and created distribution maps for each species. We confirmed 31 species from 8 families, of which 22 were associated with voucher specimens and 9 recorded based on photographs, or human observation. A further 81 species were categorized as Highly Probable (38 species), Probable (33), and Possible (10) in Bangladesh based on the distribution in neighboring states and habitat preferences. The shortfall in confirmed versus potential species highlights the need for rigorous surveys to fully document and characterize the bat diversity of Bangladesh.
