Synonyms:
Chiroderma nov. sp. Cruz, Martínez, and Fernandes, 2007: 615. Chiroderma sp. Gregorin, Carmignotto, and Percequillo, 2008: 372. Chiroderma vizottoi Taddei and Lim, 2010: 384; type locality “Teresina (ca. 05° 02 ′ S and 42° 45 ′ W), in the State of Piauí, Brazil.”
Distribution and Habitat. This subspecies is in the Brazilian states of Ceará, Maranhão, and Piauí (Fig. 23). A specimen from the Caatinga of Piauí was captured in an area with low xerophytic trees (3 to 5 meters high), next to a rocky outcrop (Gregorin et al. 2008). Two specimens from Maranhão were captured in mist nets set on the beach, in a mosaic of sandbank and mangrove vegetation.
Remarks. Lund (1842a: 134, 1842b: 200), in his studies on the extant and fossil fauna of Lagoa Santa, Minas Gerais, recorded Phyllostoma dorsale among the living species of the region. In both publications, Lund clearly uses Phyllostoma dorsale as a new name, as evidenced by the “m.” (= mihi) following the name. Because the name is present only in a faunal list, and no formal description is given, Phyllostoma dorsale Lund is considered a nomen nudum for nomenclatural purposes (see article 12 of the ICZN 1999).
Gray (1866), in his revision of Phyllostomidae, listed two species in Chiroderma, C. villosum and C. pictum. The latter name is a nomen nudum, because it lacks a description. We include Chiroderma pictum in the synonymy of Chiroderma doriae because, in the Dobson’s (1878) catalogue of bats in the British Museum, the only specimen of Chiroderma in the collection at the time of Gray’s (1866) publication was the specimen that later became the type of Chiroderma doriae. The Latin word pictus means “painted”, or “decorated”, suggesting that Gray referred to the conspicuous facial stripes, observable that specimen, a characteristic differentiating this species from Peters’ C. villosum, which was the only other Chiroderma known at that time.
Dobson (1878), in his description of Chiroderma salvini, compared the type with a specimen from Minas Gerais (Brazil) identified by him as Chiroderma villosum. However, Thomas (1891), based on an unpublished plate by Wilhelm Peters, available in the Genova Natural History Museum, recognized that the Minas Gerais specimen Dobson identified as Chiroderma villosum did not represent Chiroderma villosum Peters, 1860. Thomas (1891) described that specimen as Chiroderma doriae.
Winge (1892), studying the material sent by Lund to the Copenhagen museum, identified as Chiroderma villosum the material referred to Lund as Phyllostoma dorsale. Winge (1892: 9) located, among the Lagoa Santa specimens representing extant taxa, five fluid-preserved specimens, two skeletons, and three skins. Among the fossil material, Winge mentioned only post-cranial elements from Lapa da Escrivaninha and a cave he did not identify.
Thomas (1893), after receiving part of the Lagoa Santa material Winge identified as Chiroderma villosum, correctly identified the skull as belonging to C. doriae. This publication is the first to ascertain that Phyllostoma dorsale of Lund was the same taxon that Thomas (1891) described as Chiroderma doriae. The specimen collected by Lund at Lagoa Santa (BMNH 93.1.9.16) and examined by us is probably the same specimen donated by Winge to the British Museum and mentioned by Thomas (1893).
Aside from the Lagoa Santa specimens and the holotype, all from Minas Gerais, no additional specimen of C. doriae were mentioned in the literature for 86 years. Probably for this reason, publications that mentioned the species cited only Minas Gerais as a locality of occurrence and repeated the morphological characteristics mentioned in the original description (Vieira 1942; Cabrera 1958). It is important to note, however, that the BMNH houses specimens of C. doriae collected in the beginning of the 20 th century, by Alphonse Robert in Ypanema, currently Floresta Nacional de Ipanema, São Paulo (BMNH 3.7.1.163), and by Wilhelm Ehrhardt in Joinville, Santa Catarina (BMNH 9.11.19.15).
Taddei (1979) published the first study including new data on C. doriae since Thomas’s report in 1893. When he redescribed the taxon based on 39 specimens of C. d. doriae collected in northwestern São Paulo, Taddei (1979) confirmed the presence of a conspicuous dorsal stripe previous authors had considered to be absent.
Natural History. C. d. doriae is secondarily granivorous, specialized in chewing and grinding seeds of the fruits of Ficus to extract their nutritional content (Taddei 1980; Nogueira & Peracchi 2001, 2003). Four species of Ficus have been documented in the diet of C. d. doriae: Ficus clusiaefolia, F. cyclophylla, F. organensis, and F. tomentella (Sipinski & Reis 1995; Esbérard et al. 1996; Nogueira & Peracchi 2001). Individuals of C. d. doriae have been captured near to or visiting fruiting trees of Cecropia glaziovii (Urticaceae), Ficus enormis, F. gomeleira, and Muntingia calabura (Muntingiaceae), suggesting that this bat also consumes the fruits of these species (Taddei 1980; Esbérard et al. 1996). In addition to figs, fruits and infructescences of Cecropia pachystachya, Chlorophora tinctoria (Moraceae), Piper sp., and Psychotria suterella (Rubiaceae) are also consumed (Taddei 1973; Esbérard et al. 1996; Nogueira & Peracchi 2001; Novaes et al. 2010; Laurindo et al. 2017). Individuals of C. d. doriae have been found covered in the pollen of Mabea fistulifera (Euphorbiaceae) and of an unidentified species, suggesting that the bat also feeds on flowers (Esbérard et al. 1996; Olmos & Boulhosa 2000).
Day roosts used by C. d. doriae are not known (see review in Garbino & Tavares 2018b), but there are two records from caves, the use of which may be occasional: one in the state of São Paulo (Arnone 2008) and the other in Minas Gerais (information on specimen UFMG 4953). In the Cerrado of São Carlos, southeastern Brazil, the species was found in pellets of the Stygian Owl (Asio stygius) by Motta-Junior & Taddei (1992).
At localities in southeastern Brazil where they occur in sympatry, C. d. doriae is usually captured in much higher numbers than C. v. villosum when mist nets are set at ground level. At the Rio de Janeiro Botanical Garden, eight nights of ground-level mist netting resulted in the capture of 49 C. d. doriae and 5 C. v. villosum (Nogueira & Peracchi 2003). In Mirassol, São Paulo, 24 C. d. doriae and 6 C. v. villosum were captured in ground-level nets (Taddei 1979). In contrast, Gregorin et al. (2017), using canopy mist nets placed between 11 and 19.5 m above ground in the Parque Estadual do Rio Doce, Minas Gerais, captured 1 C. d. doriae and 24 C. v. villosum. The anecdotical report of Taddei (1980) describes the approach by C. d. doriae to fruiting trees as a low flight. Although the literature on the ecology of C. d. doriae is scarce when compared to that for C. gorgasi, C. trinitatum, and C. villosum, it suggests that the species is not as much a canopy frugivore as the other species.
Five species of ectoparasites are known from C. d. doriae: Aspidoptera falcata (Streblidae), Megistopoda proxima (Streblidae), Strebla guajiro (Streblidae), and Trichobius joblingi (Streblidae) in Sergipe; and the mite Periglischrus iheringi (Spinturnicidae) recorded on individuals from Mato Grosso do Sul, Rio de Janeiro, and in Paraguay (Presley 2004; Lourenço et al. 2016; Lima Silva et al. 2017; Soares et al. 2017). Lourenço et al. (2018) found a trypanosomatid parasite in the blood of C. d. doriae from Distrito Federal, Brazil.
The reproductive pattern is seasonal polyestry (Taddei 1980). Pregnancies were recorded in June through October, with earlier stages reported in June and July, and females with advanced fetuses recorded from August through October (Taddei 1980; Esbérard et al. 1996). Births of single young occur between October and January, suggesting a gestation period of at least three and half months (Taddei 1980). Females simultaneously pregnant and lactating are common, indicating postpartum estrus and the production of two young per year, with a second birth period in February and March (Taddei 1976, 1980; Esbérard et al. 1996).
The natural history of C. d. vizottoi is poorly known. In Ceará, seven specimens were mist netted close to an unidentified fruiting Moraceae; one was pregnant and another lactating when captured in January (Silva et al. 2015). In Maranhão, a male and female were caught in a mist net placed along the beach in a small fishing community next to a mangrove swamp near regenerating rain forest and a “babaçual” (Attalea speciosa [Arecaceae]) palm grove. The mist-net was set in front of a tree locally called “agarra” or “amapá” (Apocynaceae?), and one of the bats had its abdomen covered with a sticky material resembling a milky sap, or latex. Almeida et al. (2016) recorded the mite Periglischrus iheringi (Spinturnicidae) on C. d. vizottoi in Ceará.
