We report here a set of observations on mating behavior and female accompaniment by the whiptail lizard Cnemidophorus ocellifer in an area of Caatinga (xerophilous open forests) in the state of Rio Grande do Norte, northeastern Brazil. We observed a stationary male lizard performing repeated vibratory movements of the pelvis and tail base upon the sandy soil. Since that male was in front of a burrow in which a female of the same species was sheltered, we hypothesize that this behavior may be part of a courtship display. We continued the observation and later, when the female emerged from the burrow, the male climbed on her and the copulation occurred. The incident of accompaniment observed was characterized by one male continuously accompanying a female during foraging. Plausible functional explanations for a male accompany a female include mating guarding, post-copulatory courtship, and sperm loading. By accompanying females, males would be guaranteeing insemination by multiple copulation and stimulation of the female, and protecting their paternity by chasing away other males, diminishing the chances of extra-pair copulations.

We provide the first record of Anolis fuscoauratus D’Orbigny, 1837 for the state of Rio Grande do Norte and a distribution map for the species in the Atlantic Rainforest of northeastern Brazil. The record of A. fuscoauratus in the municipality of Tibau do Sul, state of Rio Grande do Norte, represents a distribution extension of 170 km northwestern from the municipality of Cabedelo, state of Paraíba. This is the northernmost record of this species in the Atlantic Rainforest.

This study provides the first record of the exotic invasive bivalve Isognomon bicolor for the State of Paraíba, Northeastern Brazil. It has been found to occur in at least twelve coastal reefs along the coast. We also present its first record for the State of Alagoas and new record localities for the States of Rio Grande do Norte and Pernambuco, including its occurrence in hypersaline estuaries. From these records the distribution range of I. bicolor has been expanded to the littoral region of Northeast Brazil, where this invasive species seems well established.

ABSTRACT Objective: To analyze the spatial distribution of congenital syphilis cases in a state in northeastern Brazil. Method: This is an ecological study, with secondary data for the period from 2008 to 2018, taking as a sample the notified cases of congenital syphilis in Rio Grande do Norte. In the data analysis, the eight health regions of the state were used as units of analysis, and the local and global Moran’s I was performed, with subsequent smoothing through the local empirical Bayesian method, which resulted in thematic maps. Results: The results showed an increase in cases of congenital syphilis in the 3rd and 7thhealth regions. In terms of spatial analysis, this investigation showed clusters in the 3rd, 5th, and 7thhealth regions, with an increased risk for congenital syphilis of up to 2.65 times and with an incidence rate of 7.91 cases per 1,000 live births. Conclusion: The spatial analysis of congenital syphilis cases allowed observing a high incidence in some health regions, with averages above those calculated for the entire state, indicating the need to implement effective strategies to achieve its control.

The Bromeliaceae Flora for the state of Rio Grande do Norte, Northeastern Brazil, is presented, based on extensive fieldwork, morphological analyses using herbarium and freshly collected material, and specialized literature. Twenty-six species of bromeliads were recorded in Rio Grande do Norte, distributed in ten genera and in three subfamilies. Bromelioideae was the richest subfamily (eight genera/14 species), followed by Tillandsioideae (one genus/12 species), and Pitcairnioideae (one genus/one species). Aechmea mertensii, Hohenbergia horrida and Tillandsia tenuifolia are new records for Rio Grande do Norte. Eight species (31%) are restricted to the Eastern portion of the state, in the Atlantic Forest. Caatinga dry woodlands harbor 18 species, with remarkable presence of Bromelia laciniosa, Encholirium spectabile, Tillandsia recurvata and T. streptocarpa, the four most widely distributed taxa. We discuss problems related to unclear taxonomic circumscriptions of species or diverging information between authors, more expressively in Hohenbergia, but also in Aechmea, Cryptanthus and Tillandsia. The data presented here might contribute to better understand the morphological variation of these taxa and suggest additional research on their taxonomy. Morphological descriptions, general comments, a map, photo plates and an identification key for all taxa are provided.

The present study describes a new site of occurrence for the genus Lopescladius in Brazil and reports the first record for the Piranhas-Açu River basin, in the state of Rio Grande do Norte, northeastern Brazil. This new occurrence expands the distribution of the genus and adds to the knowledge of the chironomid fauna. The presence of this genus in an intermittent stream highlights the importance of future research on this type of aquatic system as well as ecological aspects related to Lopescladius.

In the present work we describe the first occurrence of the genus Orthophytum (Bromeliaceae, Bromelioideae) and of the species Tillandsia paraibensis within the state of Rio Grande do Norte, northeastern Brazil. Both taxa were recorded on inselbergs in areas of caatinga. These findings are important, improving the knowledge of the Flora of Rio Grande do Norte and giving a better understand of the biogeography of Brazilian bromeliads.

Dilaridae is a small family of Neuroptera that includes fewer than 80 described species of which 10 are known from Brazil in the states of Amazonas, Rondônia, Rio Grande do Norte, Paraíba, Minas Gerais, Goiás, Mato Grosso do Sul, Rio de Janeiro, São Paulo, Paraná and Santa Catarina. This note includes the first record of the family for the state of Pernambuco, with the report of Nallachius dicolor Adams, 1970 in the city of Jatobá (northeastern Brazil).

Pilumnus dasypodus is reported for the first time in the state of Rio Grande do Norte, Northeastern Brazil. Sampling occurred in the north and south coast of the state in four locations (the farthest about 500 km of the known south distribution of the species). This new record increases the information about the distribution of this species, showing a possible relationship between the distribution of species and the Atlantic Tropical Ecoregion.
