(I.U.C.N. 2017.) Notes Baird et al. (2015) appeared to make a strong case of separating the genus Lasiurus into 3 genera; proposing that the genus name Lasiurus be restricted to red bats, Dasypterus be used as the genus name for yellow bats, and hoary bats plus L. egregius (which appears more closely related to hoary bats than to red bats) be reassigned to the genus Aeorestes. However, Ziegler et al. (2016) stated "That there was insufficient justification for changing the well-established zoological nomenclature for these bats, and any potential value of applying different generic names to the three clades is far outweighed by the confusion that these name changes will cause.” Therefore, the classical nomenclature for the genus is maintained in these Fact Sheets and carried over to the Interactive ID keys to the vocal signatures of the Lasiurines.

DUFFEY, Center for North American Bat Research and Conservation, Department of Ecology and Organismal Biology, Indiana State University, Terre Haute, IN 47089; Environmental Solutions & Innovations, Inc., 781 Neeb Road, Cincinnati, OH 45233 ABSTRACT. Six species of bats (n = 272) were caught at Ravenna Training and Logistics Site during summer 2004: 122 big brown bats (Eptesicus fuscus), 100 little brown myotis (Myotis lucifugus), 26 red bats (Lasiurus borealis), 19 northern myotis (Myotis septentrionalis), three hoary bats (Lasiurus cinereus), and two eastern pipistrelles (Pipistrellus subflavus). Catch was 9.7 bats/net site (SD = 10.2) and 2.4 bats/net night (SD = 2.6). No bats were captured at two net sites and only one bat was caught at one site; the largest captures were 33, 36, and 37 individuals. Five of six species were caught at two sites, 2.7 (SD = 1.4) species were caught per net site, and MacArthur’s diversity index was 2.88. Evidence of reproduction was obtained for all species. Chi-square tests indicated no difference in catch of males and reproductive females in any species or all species combined. Evidence was found of two maternity colonies each of big brown bats and little brown myotis. Capture of big brown bats (X2 = 53.738; P <0.001), little brown myotis (X2 = 21.900; P <0.001), and all species combined (X2 = 49.066; P <0.001) was greatest 1 – 2 hours after sunset.

    UWI The Online Guide to the Animals of Trinidad and Tobago Ecology Lasiurus ega (Southern Yellow Bat) Family: Vespertilionidae (Vesper or Evening Bats) Order: Chiroptera (Bats) Class: Mammalia (Mammals) Fig. 1. Southern yellow bat, Lasiurus ega. [http://www.collett-trust.org/uploads/Dasypterus%20ega5.jpg, downloaded 16 February 2016] TRAITS. Lasiurus ega is medium sized with relatively long ears and dull yellow/orange fur (Fig. 1). The span of its wing is approximately 35cm. Its mean body length is 11.8cm; tail length, 5.1cm; foot length, 0.90cm and forearm length 4.7cm and its mass ranges from 10-18g; however, the males are smaller in length and size than the females. They have a short body with a lateral projection of the upper lip and short, rounded ears (Fig. 2). The digits shorten from the 3rd to the 5th finger. Each female possesses 4 mammae whereas the males have a distally spiny penis (Kurta and Lehr, 1995). DISTRIBUTION. Found from the southwestern United States to northern Argentina and Uruguay; also can be found in Mexico and Central America (Fig. 3). The southern yellow bat is native to Trinidad. It has a seasonal migratory pattern in which it moves from the north to avoid the harsh/cold conditions (Encyclopedia of Life, 2016). UWI The Online Guide to the Animals of Trinidad and Tobago Ecology HABITAT AND ACTIVITY. The habitat of the southern yellow bat is forest which has a lot of wooded surroundings, foliage as well as palms. The bat is nocturnal in nature. Sometimes it inhabits thatched roofing and corn stalks that are dried, however they avoid entering mountainous areas.

Corresponding author: Fernando Carvalho e-mail: [email protected] Abstract Lasiurus egregius (Peters, 1870) is an insectivorous bat species known from Central and South America. This species has few confirmed records throughout its distribution. Here we report the first record of L. egregius from the northern coast of Paraná state, southern Brazil. We captured a female individual of L. egregius using an ultrathin mist-net installed over a river knee, at Salto Morato Natural Reserve, municipality of Guaraqueçaba. This is the fourteenth locality with confirmed occurrence of L. egregius, being eight of them in Brazil. The knowledge on the bat fauna in Paraná has been increasing in recent decades, mainly due to the new studies in coast areas of this state.
