Redescription of the Amazonian tiny tree toad Amazophrynella minuta (Melin, 1941) (Anura: Bufonidae) from its type locality

The description of Amazophrynella minuta was published in 1941 by the Swedish naturalist Douglas Melin based on material from Taracuá (Amazonas state, Brazil). This description was very brief and based on the morphology of few specimens with diagnostic characters and color variation not well defined. Moreover, the type series is currently in poor state of conservation. Consequently, taxonomic ambiguity surrounds the nominal taxon A. minuta, which hampers the description of many unnamed congeneric species. Herein, we redescribe A. minuta based on recently collected specimens from the type locality, designate a lectotype, formulate a new diagnosis, provide patterns of morphological variation, measurements and body proportions.

The fossorial snake Apostolepis kikoi Santos et al., 2018 is known only from its type locality, in Chapada dos Guimarães, state of Mato Grosso, Brazil. Here, we present the first records of this species after its description, expanding its distribution to transition areas between the Amazon and Cerrado biomes, in the southwestern portion of Mato Grosso. The new record expands the known distribution of A. kikoi by 297 km west from the type locality. In addition, we provide data on morphological variation by comparing our sample with the type series.

Species Type

There are currently seven species of small frogs (up to 30 mm in snout-vent length) in the genus Paratelmatobius Lutz & Carvalho 1958 (Frost, 2020). They are all endemic to mountain ranges in the Atlantic Forest, occurring in the Serra do Mar and Serra da Mantiqueira, southeastern Brazil (Santos et al. 2019). Most congeneric species are considered rare and their distribution is restricted to small areas (Domenico et al. 2014; Santos et al. 2020). Paratelmatobius mantiqueira Pombal & Haddad 1999 is one of the most enigmatic species in the genus. It hadn’t been seen from 1953, when the type series was collected, until 2005, when one specimen was found in the municipality of Resende, state of Rio de Janeiro (Vrcibradic et al. 2010). Recently, we found a new population of P. mantiqueira in the state of São Paulo. While reviewing the scattered information available about the species, we noticed inconsistencies related to the species’ type locality. We propose its rectification in this manuscript.

Doubtful Species

The systematics of the fossil representatives of Ranina Lamark, 1810, has been discussed by several authors in the last century, showing some problematics above all due to the lack of a close diagnosis of the type species (R. ranina) and to the scarce number of well-preserved type series of each fossil species. However, based upon a close comparison among the type series of each species, authors’ original descriptions, and the main diagnostic characters of Ranina, this preliminary review finds that twelve species have to be considered as doubtful species within Ranina, as follows: ?Ranina americana Withers, 1924, ?R. berglundi Squires & Demetrion, 1992, ?R. bouilleana A. Milne Edwards, 1872, ?R. brevispina Lőrenthey, 1898, ?R. granulosa A. Milne Edwards, 1872, ?R. griesbachi Noetling, 1897, ?R. haszlinskyi Reuss, 1859, ?R. libyca (Van Straelen, 1935), ?R. molengraaffi Van Straelen, 1924, ?R. oblonga (von Münster, 1840), ?R. ornata De Angeli & Beschin, 2011, and ?R. speciosa (von Münster, 1840). Four species have to be considered as Ranina nomina dubia, as follows: Ranina elegans Rathbun, 1945, R. hirsuta (Schafhäutl, 1863), R. lamiensis Rathbun, 1945, and R. tejoniana Rathbun, 1926. Ranina bavarica Ebert, 1887, R. fabri Schafhäutl, 1863, and R. helii Schafhäutl, 1863, have to be assigned to Lophoranina Fabiani, 1910. Ranina cuspidata Guppy, 1909, has to be assigned to Calappa Weber, 1795 (Calappidae De Haan, 1833). Finally, R. burleighensis Holland in Holland & Cvancara, 1958, has to be considered as doubtful species within Decapoda.

AbstractPsephophorus polygonus Meyer, 1847, the first fossil leatherback turtle to be named, was described on the basis of shell ossicles from the middle Miocene (MN6–7/8?) of Slovakia. The whereabouts of this material is uncertain but a slab on display at the Naturhistorisches Museum Wien is considered the neotype. We rediscovered further type locality ossicles in four European institutions, re-evaluated their gross morphology and described for the first time their microstructure by comparing them with Dermochelys coriacea, the only living dermochelyid turtle. The gross morphology is congruent with that already described for P. polygonus, but with two significant exceptions: the ridged ossicles of P. polygonus may have a distinctly concave ventral surface as well as a tectiform shape in cross-section. They do not develop the external keel typical of many ossicles of D. coriacea. Both ridged and non-ridged ossicles of P. polygonus are characterized by compact diploe structures with an internal cortex consisting of a coarse fibrous meshwork, whereas the proportionately thinner ossicles of D. coriacea tend to lose the internal cortex, and thus their diploe, during ontogeny. The ossicles of both P. polygonus and D. coriacea differ from those of other lineages of amniotes whose carapace is composed of polygonal ossicles or platelets, in having growth centres situated at the plate centres just interior to the external bone surface and not within the cancellous core or closer to the internal compact layer. The new diagnosis of P. polygonus allows us to preliminarily re-evaluate the taxonomy of some of the Psephophorus-like species. Despite some macro- and micromorphological differences, it seems likely that Psephophorus was as cosmopolitan as extant Dermochelys and had a broadly similar ecology, with a possible difference concerning the dive depth.

Scinax hayii was described in 1909 from the municipality of Petrópolis, State of Rio de Janeiro, Brazil. Morphological variation and advertisement calls have been previously reported for other populations across the species distribution (Lutz 1973; Heyer et al. 1990; Cardoso & Andrade 1991; Pombal et al. 1995; Magrini et al. 2011; Abrunhosa et al. 2014). However, no information on calls are available from specimens recorded at the type locality, preventing the correct characterization of the species (Magrini et al. 2011). Here we describe the advertisement call and a second call type of S. hayii from Petrópolis, as a contribution towards a better understanding of the taxonomy of this species.

A reconsideration of the diagnostic characters of Atya Leach and Atyoida Randall supports their generic separation. Accordingly, Atyoida is reinstated as a full genus of which the distinguishing features are slender third peraeopods with a relatively short merus, a tapering endopod in the male first pleopod and protandry. It includes three species, A. bisulcata Randall from the Hawaiian Islands, A. pilipes (Newport) widespread in the Indo-Pacific area, and A. striolata (McCulloch & McNeill) found only in Australia. A. striolata is fully redescribed. Morphological variation throughout its range is slight; no subspecies are distinguishable. It is suggested that larvae hatch in estuaries and that protandry is an adaptive life-cycle strategy.

The discovery of the first damselfly Lestes regina Théobald, 1937 from Monteils (Gard, France) supports the identity of late Eocene age of this outcrop with the historical outcrop of Célas, type locality for the type series of this species. Lestes regina is also documented from the late Eocene Isle of Wight basin, confirming the presence of significant contacts between this southern area and the anglo-Parisian lacustrine basin at that time. Nearly all the Eocene and Oligocene fossil Lestes from Western Europe have a particular character, viz. the presence of a supplementary row of cells between the veins MP and CuA. This character is much less frequent in extant Lestes and is still unknown among Neogene representatives of the genus.

Horseshoe Canyon Formation

The type series of Albertosaurus sarcophagus , consisting of a type (CMN 5600) and a paratype (CMN 5601) is inadequately established, since it has not been demonstrated that the specimens represent the same taxon. This problem has arisen because the original diagnostic characters have a wider distribution among Tyrannosauridae or they are in error, and both specimens consist of incomplete and damaged skulls. The type series was studied to test for the presence of diagnostic characters in the type specimen and, if so, to provide a rationale for referring the paratype to the taxon. Of the bones shared between the skulls, only five could be compared. One character, the enlarged posterior pneumatic recess of the palatine, is shared between the two specimens; this condition differs from the situation seen in other tyrannosaurids. This character provided the rationale for assessing the identity of the specimens collected from the Albertosaurus bonebed, from which one palatine was collected that exhibits the diagnostic recess. Isolated cranial bones from the bonebed were compared with those preserved in the type series to evaluate their referral to A. sarcophagus ; additional characters shared between the type series and the specimens from the bonebed were identified in the maxilla, lacrimal, and palatine. This evidence supports the hypothesis that A. sarcophagus is the tyrannosaurid preserved in the bonebed. A hypothesis of the principal growth changes in the skull in A. sarcophagus, which includes the type series and bonebed material, is proposed.
