We report new observations of the globally threatened Minas Gerais Tyrannulet Phylloscartes roquettei from two areas in the São Francisco Valley, Minas Gerais, Brazil, between July 1993 and February 2002. Four pairs, one fledged young and two lone individuals were observed in the course of our fieldwork. It was previously known only from a female taken in the mid-1920s and sight records and tape-recordings in 1977. Our records extend the species' known range 250 km south and west of the type-locality region. Details of the first-known male specimen are presented, along with novel data concerning its vocalizations and behaviour. We draw attention to the possible relationship of the species to a group of four other Phylloscartes tyrannulets with similarly patterned faces and overall plumage, which exhibit a similar circum-Amazonian distribution pattern to three Phyllomyias tyrannulets. We also take the opportunity to draw more attention to the imperilled conservation status of the dry forests upon which P. roquettei and a host of other threatened and Near-threatened avian taxa depend.

In this paper, we describe Coarazuphium lundi sp. nov., from a single male specimen collected in Gruta 06L cave located in the municipality of Prudente de Morais (Minas Gerais state, Brazil). The two most striking differences between C. lundi and other species of the genus is the presence of two pairs of posterior supraorbital setae and the elytra shape with parallel, not rounded sides. Coarazuphium pains Álvares & Ferreira 2002 is an endemic species restricted to a few caves at the Bambuí Carbonatic Group in the midwest of Minas Gerais state, Brazil. The holotype of C. pains was unfortunately lost in 2010, due to a fire that destroyed almost the entire zoological collection at the Butantã Institute, São Paulo state in Brazil. In recent years, several species of the genus have been described and compared to C. pains only based on its paper description, clearly prompting the need for the C. pains neotype designation. In order to provide a necessary standard for comparison, a neotype is designed for this species based on the material collected from the best approximation of the type locality (caves). Lastly, we also provide a brief discussion on the presence of eyespots of C. cessaima, originally described as blind.

Schendylops janelao sp. n. is described from a limestone cave located in eastern Brazil. There are several reports of geophilomorphs in Brazilian caves, however, the new species represents the first troglobite species for South America and the first for Gruta do Janelão Cave, northern Minas Gerais State. Schendylops janelao sp. n. is described based on a male specimen and differs from its congeners by a combination of 10 characters. We discuss the character-states related to subterranean life and the conservation status of the species.

A New Species

A new species, Calea arachnoidea, which belongs to Calea sect. Meyeria, is hereby described and illustrated. This species occurs in the Serra Negra region, located in the southern portion of the “Zona da Mata” in the state of Minas Gerais, southeastern Brazil. Calea arachnoidea resembles C. quadrifolia, C. heteropappa and C. semirii, and its relationships with these species are discussed and an identification key for the species of C. sect. Meyeria in the state of Minas Gerais is provided. Additionally, photographs, a distribution map, comments about habitat and conservation status are provided.

A New Species

Pseudancistrus reus is a new species from the Río Caroní (Río Orinoco drainage) of Venezuela known from two individuals. It differs from all other Pseudancistrus by having a color pattern consisting of alternating dark and light bars. In addition, it differs from all except P. genisetiger and P. papariae by having an incomplete mid-dorsal plate row and from P. genisetiger and P. papariae by having 18 contiguous mid-dorsal plates vs. 14 plates, a plateless break and then two more plates at the end of the caudal peduncle. The type locality of P. reus was submerged by the construction of the Caruachi dam, and is also the only known locality of the gymnotiform Sternarchorhynchus gnomus, making it imperative that the conservation status of these and other potential Caroní endemics be assessed. Pseudancistrus reus is the first species of Pseudancistrus sensu stricto from the Orinoco. Although the relationship of the species to other Pseudancistrus is unknown, P. reus may have gained access to the Orinoco either via stream capture between the Caroní and the Rio Uraricoera (Rio Branco – Rio Negro drainage) or via stream capture between the Caroní and either the Cuyuní or Mazaruni Rivers (Essequibo River drainage).key word: Siluriformes, Loricariidae, taxonomySe describe como especie nueva Pseudancistrus reus del río Caroní (cuenca del río Orinoco) en Venezuela, basada en dos ejemplares. Difiere de todas los demás Pseudancistrus en tener un patrón de pigmentación que consiste de barras claras alternando con oscuras. Además, difiere de todas los demás, menos P. genisetiger y P. papariae en tener la fila medio-dorsal de placas incompleta, y de P. genisetiger y P. papariae difiere en tener 18 placas medio-dorsales contiguas vs. 14 placas seguidas por una zona sin placas y luego dos placas más en el pedúnculo caudal). La localidad típica de P. reus fue sumergida por las aguas del embalse Caruachi. Ese sitio es también la localidad típica de Sternarchorhynchus gnomus, haciéndolo imprescindible evaluar el estado de conservación de estas dos especies más las otras endémicas del bajo Caroní. Pseudancistrus reus es la primera especies de Pseudancistrus sensu stricto de la cuenca del río Orinoco. Aunque desconocemos las relaciones con otras Pseudancistrus, P. reus puede haber ganado acceso al Caroní vía la captura de caños en las cabeceras del río Uraricoera-Branco-Negro o del río Cuyuní o Mazaruni, afluentes del río Essequibo.

Sympatric Cytotypes

Specimens of Hoplias malabaricus from Lagoa Carioca, an isolated lake of the Rio Doce State Park (state of Minas Gerais, Brazil), were cytogenetically studied. The diploid number was found to be constant, i.e., 2n = 42 chromosomes, although two karyotypic forms were found: karyotype A, characterized by 22M + 20SM chromosomes, observed only in a male specimen, and karyotype B, characterized by 24M + 16SM + 2ST and 24M + 17SM + 1ST chromosomes in female and male specimens, respectively. This sex difference found in karyotype B is related to an XX/XY sex chromosome system. Another female specimen of H. malabaricus, also carrying karyotype A, had previously been found in the same lake. The available data indicate that two sympatric cytotypes of H. malabaricus exist in the Lagoa Carioca, with cytotype A occurring at a lower frequency and differing from cytotype B by undifferentiated sex chromosomes.

In this study we report the first record of the giant torrent frog Megaelosia apuana in the state of Minas Gerais, southeastern Brazil. The finding of this species at Reserva Particular do Patrimônio Natural (RPPN) Mata do Sossego, municipality of Simonésia, east of Minas Gerais extends its geographic distribution by 120 km from the type locality, and 45 km northwest from its westernmost known record. A geographic distribution map is presented.
