description: 32. Schulz’s Round-eared Bat <i>Lophostoma schulzi</i> <b>French:</b> Lophostome de Schulz / <b>German:</b> Schulz-Rundohrblattnase / <b>Spanish:</b> Lofostoma de Schulz <b>Taxonomy.</b> Tonatia schulzi Genoways &amp; S.L. Williams, 1980, “ 3 km SW Rudi Kappelvliegveld, 320 m, Brokopondo, Suriname.” A phylogenetic analysis of genetic data revalidated the genus Lophostoma for species that were previously in Tonatia, except TI: bidens and 1. saurophila, thus reassigning brasiliense, carriken, evotis, schulzi, and silvicola to Lophostoma. Monotypic. <b>Distribution.</b> Endemic to the Guianas and N Brazil (Amazonas, Para, and Amapastates). <b>Descriptive notes.</b> Head-body 63-69 mm, tail 12-13 mm, ear 27-29 mm, hindfoot 11-6 14 mm, forearm 42-45 mm; weight 15 g. Greater lengths of skulls are 22-8-24 mm. Schulz’s Round-eared Bat is medium-sized and only larger than the Pygmy Round-eared Bat (L. brasiliense). It can be distinguished by small wartlike granulations on dorsal surfaces of forearms, digits, calcars, hindlimbs, ears, and noseleaf (characteristics not found in any other phyllostomid). Dorsal hairs are pale brown, with pale bases, becoming almost white. It has post-auricular patches that are sparsely haired and paler than back. Venteris slightly paler than dorsum and can vary markedly among adults, ranging from medium gray to almost white, and younger adults have darker venters, suggesting that ventral pelage becomes paler with age. Ears are long, with single low band ofskin running from each ear and meeting in middle of forehead;tragus is attenuated but with distinctive prominent projection on inner margin. Calcar is longer than hindfoot. Schulz’s Round-eared Bat resembles other species of Lophostoma by having narrow I. It has been recorded that clitoris of a female Schulz’s Round-eared Bat is remarkably elongated and resembles a penis, unlike congeners that have intermediate stages of elongation. <b>Habitat.</b> Tropical lowland and lower montane rainforests (Guiana highland regions) above elevations of 1500 m. Schulz’s Round-eared Bats are mainly recorded in primary forests, characterized by dense vegetation where understory often provides moderate groundcover, but they also inhabit regenerating secondary forests in Brazil. <b>Food and Feeding.</b> Schulz’s Round-eared Bat is a generalist, gleaning insectivore. It might prefer large insects such as beetles and katydids. <b>Breeding.</b> A female taken in August in French Guiana had a 28 mm length (crown— rump) fetus. <b>Activity patterns.</b> Schulz’s Round-eared Batis nocturnal. Some behavior is expected to be similar to that of its congeners, so it might roost in large active arboreal hymenopteran (termites or ants) nests that are excavated and maintained. <b>Movements, Home range and Social organization.</b> No information. <b>Status and Conservation.</b> Classified as Least Concern on The IUCN Red List. <b>Bibliography.</b> Farneda et al.
