A New Species

The fossil cricket Araripegryllus romualdoi was described by Freitas et al. (2016) based on a single, very poorly preserved specimen from the Romualdo Member of the Lower Cretaceous Santana Formation; a deposit famed for the exceptional preservation of vertebrates in carbonate concretions (Martill, 1996, 2007). While abundant and diverse in the underlying Crato Formation (Martill et al., 2007 and contributions therein), fossil insects had not been reported from the Santana Formation prior to Freitas et al.’s paper. The occurrence of an insect in the Santana Formation is certainly noteworthy, but the description of a new species and its placement in the genus Araripegryllus are problematic, primarily because of the very poor preservation of the specimen. Here, problems associated with the diagnosis and placement of A. romualdoi are outlined, and the species declared a nomen dubium.

A New Species

AbstractA new fossil Brachycera (Diptera), Cratomyia macrorrhyncha gen. n. & sp. n. is described from the Santana Formation, Lower Cretaceous, situated on the Araripe Basin (Northeastern Brazil). Its remarkable features are the large body size, very long proboscis, antenna with multi-articled flagellum, robust thorax and abdomen, and wing characters like the abbreviated costal vein, distally forked veins R4+5 and M1+2, strongly arched M1, and closed cells m3 and cup. The new genus and species does not reasonably fit in any of the existing families and a new family, Cratomyiidae is proposed. The systematic position of the family is discussed. Reasons are given for not including it in the following higher taxa of Brachycera: Xylophagomorpha, Tabanomorpha, Vermileonomorpha, Asilomorpha, and Eremoneura. The Cratomyiidae are included in Stratiomyomorpha as the sister-group of Xylomyidae + Stratiomyidae, above the origin of Pantophthalmidae.

A New Species

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

A New Species

Abstract—Justicia rubrobracteata, a new species from northeastern Brazil, is described and illustrated. The new species is morphologically similar to J. aequilabris due to its shrubby habit, and terminal and axillary spicate inflorescences with red flowers. However, J. rubrobracteata is differentiated mainly by the shape and color of its bracts and bracteoles as well as an orangish macula in the corolla, and a torulose capsule. In addition, J. rubrobracteata is only known from northeastern Brazil, from the states of Paraíba and Rio Grande do Norte, while J. aequilabris is widely distributed in Bolivia, Brazil, and Paraguay. A table with the main morphological characters of both species is included, as well as photographs, a key to species of Justicia for the states of Paraíba and Rio Grande do Norte in northeastern Brazil, a distribution map of both species, and conservation data for the new species.

A New Species

A new species of scaly blenny, Labrisomus conditus sp. n., is described from Fernando de Noronha Archipelago, off northeastern Brazil. It differs from its Western Atlantic congeners by the following combination of characters: nuchal cirri when depressed not reaching dorsal-fin origin, 68 to 73 lateral line scales, first and second dorsal-fin spines slightly shorter than third spine and not flexible, numerous pale dots overall (light blue in life), opercular dark spot with incomplete and diffuse broad pale margin (orange in life). The new species is a territorial bottom-dweller in rocky shores and is found among algae and in crevices at depths from 0.5 to 6 m. Labrisomus conditus sp. n. feeds mostly on crustaceans (crabs, amphipods) and molluscs (snails, bivalves). The new species increases to five the species within the genus Labrisomus recorded from Southwestern Atlantic.
