Three New Species

Three new species of Anaulacomera are described, Anaulacomera (Anaulacomera) mariellae sp. n. and Anaulacomera (Anallomes) arlindoi sp. n., belonging respectively to the Inermis and Lanceolata species group, and Anaulacomera angelinae sp. n., placed as incertae sedis. The individuals were collected at the Iguaçu National Park and adjacent small fragments of Atlantic Forest, in southwestern Paraná state, Brazil. The description was based on external morphology of males. We also present distribution maps for the species of the Inermis and the Lanceolata species groups.

Leptodactylus cupreus Caramaschi, Feio & São Pedro is allocated in the L. fuscus species group, within the L. mystaceus species complex (sensu Heyer 1978 and Heyer et al. 1996; Caramaschi et al. 2008), that is formed by medium sized frogs distributed throughout the Amazon Basin, Atlantic Forest, Gran Chaco and Cerrados of South America (de Sá et al. 2005). This species complex includes L. mystaceus (Spix), L. elenae Heyer, L. notoaktites Heyer, L. spixi Heyer, and L. didymus Heyer, García-Lopez & Cardoso. The tadpoles of L. didymus and L. cupreus are still unknown. Herein we describe the tadpole of L. cupreus and compare it with other species of the L. mystaceus complex for which tadpole descriptions are available.

Scinax juncae is a hylid frog inhabiting the forest edge in Atlantic Forest remnants in the southern State of Bahia, Brazil (Nunes & Pombal Jr. 2010). This specie is morphologically similar to Scinax auratus (Wied-Neuwied) and Scinax cretatus Nunes & Pombal Jr. (Nunes & Pombal Jr. 2010, 2011), both of them also inhabit the Atlantic Forest in the Northeast of Brazil. We describe herein the previously unknown tadpole of Scinax juncae and compare it with tadpoles of other species of Scinax ruber species group sensu Faivovich et al. (2005) distributed in the lowlands of the Atlantic Forest (Nunes & Pombal Jr. 2010).

Three New Species

The gigas species group of the subgenus Canthidium (Neocanthidium) is defined and described. This species group is composed of three described species [C. gigas Balthasar, 1939, Brazilian Atlantic Forest, including intrusions into Cerrado, C. bokermanni (Martínez et al., 1964), Chaco and western Cerrado in Brazil, Bolivia, Paraguay, and Argentina, and C. kelleri (Martínez et al., 1964), Brazilian Cerrado and neighbouring open areas] and three new species: Canthidium stofeli sp. nov. from the western and southern regions of the Brazilian Amazon, Canthidium feeri sp. nov. from French Guiana, and Canthidium ayri sp. nov. from the Brazilian Atlantic Forest. We present descriptions and redescriptions, illustrations, an identification key and comments on the distributions of the species of the gigas group.

A New Species

There are 130 described species in the genus Mycodrosophila Oldenberg, 1914, distributed across all biogeographic regions. Most of these species show essential mycophagy. Currently, ten species are known from the Neotropical Region, nine of which are found in the Amazon, Atlantic Forest, Cerrado and Pampa biomes of Brazil. In this study, we describe the adult external morphology and structures of male and/or female terminalia for two new species from the Amazon Biome of Brazil. In addition, we propose a new species group, the Mycodrosophila neoprojectans group, encompassing the two new species described here, together with three previously described species from the Neotropics.

Species Groups

The Neotropical genus Scinax Wagler currently comprises 127 species of small treefrogs distributed from southern Mexico to Argentina and Uruguay, including some islands such as Trinidad and Tobago, and St. Lucia (Frost 2020). Two major clades are recognized within Scinax, the S. catharinae and the S. ruber clades. The former is composed of two species groups, the S. catharinae and the S. perpusillus groups (Faivovich 2002; Faivovich et al. 2005). The S. perpusillus species group currently comprises 13 species: S. alcatraz (Lutz); S. arduous Peixoto; S. atratus (Peixoto); S. belloni Faivovich, Gasparini & Haddad; S. cosenzai Lacerda, Peixoto & Feio; S. faivovichi Brasileiro, Oyamaguchi & Haddad; S. insperatus Silva & Alves-Silva; S. littoreus (Peixoto); S. melloi (Peixoto), S. peixotoi Brasileiro, Haddad, Sawaya & Martins; S. perpusillus (Lutz & Lutz); S. tupinamba Silva & Alves-Silva; and S. v-signatus (Lutz). These species are endemic of the Brazilian Atlantic Forest and are recognized by their intimate association with bromeliads (Fig. 1), in which adults breed and lay their eggs, and tadpoles develop (Peixoto 1987, 1995; Alves-Silva & Silva 2009).

The “Probetoriformes” species group of Symmachia Hübner, [1819] proposed by Stichel (1910; 1930) is redefined based on morphological evidence, and the species herein included in the group are revised. Two new species from the Brazilian Atlantic Forest are described: S. atlantica Dias, Dolibaina & Mielke sp. nov. and S. uirassu Dolibaina, Dias & Casagrande sp. nov. Additionally, one restituted status, S. championi Godman & Salvin, 1886 stat. rest., one revalidated status, S. belti Godman & Salvin, 1886 stat. rev., and one new status, S. meyi Brévignon, 1998 stat. nov., are proposed; therefore, the “Probetoriformes” species group, as herein conceived, includes 10 of the about 60 species of the “catch-all” genus Symmachia. A neotype for Papilio probetor Stoll, 1782 and lectotypes for S. probetor form astiama Seitz, 1913, S. belti and S. championi are designated. The female of the recently described species S. divisora Dolibaina & Leite, 2012 is recognized and described for the first time. Additionally, morphologic illustrations and a dichotomous key for species of the “Probetoriformes” species group are provided.

First Time

Despite extensive taxonomic work on the Neotropical fauna of the spider genus Micrathena Sundevall, for 27 out of 117 (23%) species only the female morphology has been described, and some of the previously hypothesized male-female matches have been proven erroneous. This work provides new insight about sex matching in two species: Micrathena ruschii (Mello-Leitão, 1945) and Micrathena lata Chickering, 1960. For Micrathena ruschii, the male previously hypothesized to belong to this species was collected with females in Itatiaia; we here present morphologically different males, also collected with females, in Macaé, both in Rio de Janeiro, Brazil. Through a DNA barcoding approach, we present molecular evidence indicating conspecificity of M. ruschii females with the males collected in Macaé, proving the male from Itatiaia to be a misidentification. Therefore, a description of the correct male of Micrathena ruschii is herein provided. The male previously identified as M. ruschii probably represents an undescribed species but is not named here due to scarcity of material. We also describe for the first time the male of Micrathena lata based on one specimen collected in Misiones, Argentina. This male specimen belongs to the militaris species group, where M. lata is the only species from the Atlantic Forest previously only known by females. In addition, we detect an intersexual specimen of Micrathena ruschii, revealing the first case of intersexuality for the genus.
