“…Localization was used for eight purposes in animal behavior and ecology, with 35 studies using localization for multiple purposes (Figure 3). Twenty‐six studies assessed individual animals' positions or movement, such as responses to conspecific or interspecific disturbances (e.g., Campbell & Francis, 2012; Collier, Blumstein, et al, 2010; Langemann, Peake, Tavares, & McGregor, 2000), flight speed or style in bats (e.g., Grodzinski, Spiegel, Korine, & Holderied, 2009; Ing et al, 2016; Miller & Treat, 1993), positions of displaying male birds and frogs (e.g., Grafe, 1997; Patricelli & Krakauer, 2010), and determining the position of individual predator bats when insects' auditory organs perceived these predators (Goerlitz, ter Hofstede, Zeale, Jones, & Holderied, 2010; Roeder, 1966; Schul, Matt, & Helversen, 2000). Twenty‐four studies quantified the amplitude or directionality of animal sounds, using localization to account for the animal's distance or position in relation to the microphone; this method was especially common in studies of bats (e.g., Holderied & Helversen, 2003; Jakobsen, Olsen, & Surlykke, 2015; Lewanzik & Goerlitz, 2018), but was also used to study elephants (Hedwig, DeBellis, & Wrege, 2018; Wrege, Rowland, Keen, & Shiu, 2017) and birds (Dantzker, Deane, & Bradbury, 1999; Patricelli, Dantzker, & Bradbury, 2007, 2008).…”

Autonomous acoustic recorders are an increasingly popular method for low‐disturbance, large‐scale monitoring of sound‐producing animals, such as birds, anurans, bats, and other mammals. A specialized use of autonomous recording units (ARUs) is acoustic localization, in which a vocalizing animal is located spatially, usually by quantifying the time delay of arrival of its sound at an array of time‐synchronized microphones. To describe trends in the literature, identify considerations for field biologists who wish to use these systems, and suggest advancements that will improve the field of acoustic localization, we comprehensively review published applications of wildlife localization in terrestrial environments. We describe the wide variety of methods used to complete the five steps of acoustic localization: (1) define the research question, (2) obtain or build a time‐synchronizing microphone array, (3) deploy the array to record sounds in the field, (4) process recordings captured in the field, and (5) determine animal location using position estimation algorithms. We find eight general purposes in ecology and animal behavior for localization systems: assessing individual animals' positions or movements, localizing multiple individuals simultaneously to study their interactions, determining animals' individual identities, quantifying sound amplitude or directionality, selecting subsets of sounds for further acoustic analysis, calculating species abundance, inferring territory boundaries or habitat use, and separating animal sounds from background noise to improve species classification. We find that the labor‐intensive steps of processing recordings and estimating animal positions have not yet been automated. In the near future, we expect that increased availability of recording hardware, development of automated and open‐source localization software, and improvement of automated sound classification algorithms will broaden the use of acoustic localization. With these three advances, ecologists will be better able to embrace acoustic localization, enabling low‐disturbance, large‐scale collection of animal position data.

“…As if to confirm the previous statement, after the manuscript for this paper was submitted, Ing et al (2016) and Hassanin et al (2017) reported on ten additional specimens from Mbiye island and the Yoko Forest Reserve (00°17′ N, 25°17′ E). Hassanin et al (2017) also described a new species of Glauconycteris, which is not covered in the current paper.…”

Abstract. In 1966, Robert William Hayman, Xavier Misonne and Walter Verheyen published their listing of the Congolese, Rwandan and Burundian bat specimens in the collections in the museums of Tervuren, Brussels, Geneva, London and New York. In the fifty years that have passed since, some major changes have been introduced in the taxonomy of the Chiroptera: new species have been discovered, species have been split off, species have been moved to other genera, and additional material has been collected. We re-evaluated the data presented by Hayman et al., and supplemented this with specimen records found in the literature and in online catalogs. This resulted in 136 species, represented by 20 231 specimens (compared to 113 species and 8567 specimens originally). When available, we also recorded additional information such as locality, sex and age, collector, collection date and preservation type of the voucher specimen. The distribution maps of the Congolese taxa are revised to represent the current taxonomy, and are presented in perspective against the taxon's Species Distribution Model to assess species distribution on the African continent. Additionally, an updated key to the various taxa is presented.

“…At the end of the Miocene, around 6 ± 2 Mya, Glauconycteris diversified in Africa into three main groups, which today occupy different habitats: The lineage corresponding to G. variegata (which may also contain G. machadoi ) is predominantly associated with savannah, woodland, and bushveld habitats (Monadjem, Taylor, Cotterill, & Schoeman, ; Rambaldini, ); in the tropical rainforests, G. superba seems to be an open space forager, that is, concentrating its activity above the canopy (Ing et al., ), whereas all other species of Glauconycteris , which have a smaller size and a less conspicuous color pattern, are expected to be edge foragers, that is, exploiting the spaces immediately below the canopy, as do the majority of bat species living in Neotropical rainforests (Tiago Marques, Ramos Pereira, & Palmeirim, ). The basal diversification of Glauconycteris occurred when a brief event of aridity, between 6.5 and 6 Mya, was followed by more humid conditions (Bonnefille, ).…”

“…In G. egeria , we observed that the shoulder spot and dorsal flank stripe are confluent. In G. superba , there are two or rarely three white spots on each shoulder (Ing et al., ). In addition, two species are without body patterns or reticulated wings: G. atra sp.…”

“…The pelage of the pied butterfly bat ( Glauconycteris superba Hayman, 1939) is probably the most spectacular, with a black body strikingly marked with white spots on the head and shoulders, and white stripes on the throat, along each side of the belly, and on the back. Most species are rarely recorded and poorly known: Glauconycteris curryae Eger & Schlitter, ; Glauconycteris egeria Thomas, ; Glauconycteris gleni Peterson & Smith, ; and G. superba have been collected from only a few localities (respectively, 6, 6, 2, and 6); whereas Glauconycteris machadoi Hayman, 1963 and Glauconycteris kenyacola Peterson, 1982 are known only from the holotype (ACR ; Happold & Happold, ; Ing et al., ).…”

The genus Glauconycteris Dobson, 1875 currently contains 12 species of butterfly bats, all endemic to sub-Saharan Africa. Most species are rarely recorded, with half of the species known from less than six geographic localities. The taxonomic status of several species remains problematic. Here, we studied the systematics of butterfly bats using both morphological and molecular approaches. We examined 45 adult specimens for external anatomy and skull morphology, and investigated the phylogeny of Glauconycteris using DNA sequences from three mitochondrial genes and 116 individuals, which in addition to outgroup taxa, included nine of the twelve butterfly bat species currently recognized. Four additional nuclear genes were sequenced on a reduced sample of 69 individuals, covering the outgroup and Glauconycteris species. Our molecular results show that the genus Glauconycteris is monophyletic, and that it is the sister-group of the Asian genus Hesperoptenus.Molecular dating estimates based on either Cytb or RAG2 data sets suggest that the ancestor of Glauconycteris migrated into Africa from Asia during the Tortonian age of the Late Miocene (11.6-7.2 Mya), while the basal diversification of the crown group occurred in Africa at around 6 AE 2 Mya. The species G. superba is found to be the sister-group of G. variegata, questioning its placement in the recently
