Flora of Paraíba State, Brazil: Aechmea Ruiz & Pav. (Bromeliaceae)

Abstract: Aechmea is one of the largest genera of Bromeliaceae, having more than 250 species, and Brazil is its principal center of endemism. We taxonomically examined the species of Aechmea encountered in Paraíba State in northeastern Brazil. Our analyses were based on specimens collected during the present study, as well as examinations of local and regional herbaria collections. Eleven species were encountered to State: Aechmea aquilega, A. chrysocoma, A. costantinii, A. emmerichiae, A. eurycorymbus, A. fulgens, A. leptantha, A. mertensii, A. nudicaulis, A. patentissima, and A. werdermannii. Of those taxa, seven are endemic to northeastern Brazil and five are included within one of the threatened categories according to IUCN criteria, two of them being "endangered" and "critically endangered". We include here a key to the identification of the species, a list of the materials examined, commentaries concerning the taxonomic affinities of the species based on morphological characters, data concerning their geographic distributions, flowering, fruiting, inferences concerning their conservation statuses, as well as images and drawings indicating their principal characteristics.

Eulaema (Apeulaema) felipei sp. n., a species extremely similar to the Amazonian Eulaema (Apeulaema) mocsaryi (Friese, 1899), is described from Murici (state of Alagoas, northeastern Brazil). This species seems to be restricted to a single patch of Atlantic Forest at the ‘Estação Ecológica de Murici’. Although this preserve is supposedly protected by law, the small area (less than 3,000 ha) where this bee occurs is entirely surrounded by pastures and sugar cane plantations, and anthropic pressure is strikingly high in the region. Several other endemic animal and plant species are known from the same area. Eulaema felipei sp. n. is considered as Critically Endangered according to IUCN criteria. An updated identification key for all the species of Eulaema (Apeulaema) Moure, 1950 is also provided.

Six Eugenia species from the Atlantic Forest of Alagoas state, northeastern Brazil, are described here: Eugenia anthropophaga, E. cambemba, E. curuba, E. jussara, E. mammifera, and E. palmarina. Eugenia anthropophaga and E. jussara are morphologically similar to each other but distinguished by the ovate (vs. linear in E. jussara) bracts, fruiting pedicels not swollen (vs. swollen) at the base, and subglobose (vs. pyriform), pilose (vs. glabrescent) and deeply 8-costate (vs. slightly 8-costate) fruits with patent (vs. erect) calyx lobes. Eugenia cambemba is morphologically similar to E. valsuganana but differs by the leaf blades cuspidate at the apex, and fruits longer, obovoid, and reddish when ripe. Eugenia curuba is similar to E. pruinosa, differing by the leaf blades obtuse to rounded at the apex, with 12–14 secondary veins per side, and sessile fruits with subtly glandular-rugose surface. Eugenia mammifera differs from E. coffeifolia by the elliptic leaf blades with 14–17 secondary veins, eciliate calyx lobes, and fruits 8-costate and constricted at apex. Eugenia palmarina differs from E. barrana by the widely elliptic leaf blades with minute glandular dots on the adaxial surface, with 12–15 secondary veins per side, and longer triangular or linear bracts. Due to the restricted distribution and imminent threats, the new species are provisionally considered as Critically Endangered (CR), in accordance with the IUCN criteria. Data about geographical distribution, habitat, and comments on morphological affinities are 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.

The goal of this study was to analyze the types and distributional patterns of sensilla in Corixoidea, which is part of the approach to the phylogeny study of Nepomorpha, based on the morphological characters of sensilla. This paper presents the results of the study, with the use of a scanning electron microscope (SEM), on the antennae of species from the families Corixidae and Micronectidae. The antennal sensilla of eleven species from Corixidae and two species from Micronectidae were studied. Five main types of sensilla with several subtypes of sensilla trichodea were found and described. The study has shown that the family Corixidae has a strong uniformity when it comes to antennal sensilla (similar patterns of sensilla trichodea and basiconica), and a similarity to the types and distributions of sensilla in two species of the family Micronectidae. However, significant differences between the families were also discovered (differences in sensilla presence on the first and second antennomeres, lack of sensilla coeloconica on the third antennomere in Micronectidae), which leads to a supportive conclusion of the systematic position of Micronectidae as a family.

Research into the systematics of Prostanthera has recently revealed a close evolutionary relationship among P. phylicifolia s. str., the critically endangered P. gilesii, and a population of uncertain identity from the Central Tablelands of New South Wales, Australia. Previous analyses were unable to establish whether genetic boundaries separated these taxa. This study aimed to assess the species boundaries among these three taxa using a combination of single-nucleotide polymorphisms (SNP) sampled at the population-scale and multivariate analysis of morphological characters. Non-parametric and parametric statistics, neighbour-network analysis, phylogenetic analysis, and ancestry coefficient estimates all provided support for discrete genetic differences between the three taxa. Morphological phenetic analysis identified a suite of characters that distinguished each of these taxa. This corroboration of evidence supports the presence of three independently evolving lineages. Prostanthera gilesii and P. phylicifolia s. str. are distinct species independent from the third taxon which is described here as P. volucris R.P.O'Donnell. A detailed description, diagnostic line drawings and photographs are provided. We evaluate P. volucris as satisfying criteria to be considered Critically Endangered.

High-throughput sequencing, when combined with taxonomic expertise, is a powerful tool to refine and advance taxonomic classification, including at the species level. In the present work, a new species, Plantago campestris, is described out of the P. commersoniana species complex, based on phylogenomic and morphological evidence. The main morphological characters that distinguish the new species from P. commersoniana are the glabrous posterior sepals and the slightly broader leaves. The new species is known from only three localities, all in natural high-elevation grasslands in Paraná and Santa Catarina states, southern Brazil. According to the IUCN criteria new species should be assessed as Endangered (EN). We present field photographs of P. campestris and related species, and we provide an identification key to the species previously included within the circumscription of P. commersoniana.

Behuria mestrealvarensis (Melastomataceae) from the state of Espírito Santo, Brazil, is described, illustrated and compared with B. capixaba, the species most similar to it. Behuria mestrealvarensis differs from B. capixaba by the glabrous petioles and hypanthia, by the solitary flowers or these in simple or compound triads up to 7 flowers, elliptic bracteoles almost the same size of the pedicel and hypanthium, sepals with eciliate margins and ovary apex with trichomes up to 0.5 mm. It occurs in a single locality, on an isolated, ca. 800m elev. inselberg. Due to its restricted occupancy area, fragmented landscape and poor habitat quality, this species must be considered as Critically Endangered according to IUCN criteria.
