In this paper, we describe the first association of the ostreid species Ostrea puelchana d’Orbigny, 1842, as new epibiont in Eriphia gonagra (Fabricius, 1781), with material collected in Northeastern Brazil. The specimens of E. gonagra were collected manually in November of 2020 during the low tide in the Barra de Catuama beach, State of Pernambuco. Among 10 specimens collected, only one adult male showed the presence of two commensal specimens of O. puelchana adhered in the epibranchial and antero-lateral regions of the basibiont (right side). The presence of the epibiont O. puelchana on the new host E. gonagra expands the range of the crustacean species potentially used as hosts by this oyster along the Brazilian coast. Keywords: marine invertebrates, biological interactions, Pernambuco, commensalism, beachrocks.

Hemidactylus Mabouia

From January to April 2006, 37 specimens of Hemidactylus mabouia were collected in houses, in the municipality of Barbalha (7° 20' S and 39° 18' W), Ceará State, Northeast Brazil. Among the individuals captured, 17 were infected with pentastomids, totalling a prevalence of 45.9%, which did not differ between sexes. Host size did not influence the infection intensity. Two species of pentastomids were found: Raillietiella frenatus and R. mottae. The prevalence of R. frenatus (43.2%) was higher than R. mottae (2.7%), whereas the infection intensity of R. frenatus was comparatively lower (1.8 ± 1.4) than R. mottae (36 parasites in a single host). Overall mean intensity of infection was 3.8 ± 8.4 pentastomids. We found no pentastomid infecting juvenile geckos. The parameters of infection in this host population are in accordance to the findings of other studies, in which the high parasitism rate was associated to the feeding habits of geckos living in houses and buildings. Hemidactylus mabouia is a new host to R. mottae and the infection by R. frenatus is the first record of the occurrence this pentastomid species in Brazil.

This study aimed to evaluate the infection rates of snakes by pentastomids in the semi-arid region of Brazil. Fifteen snakes (four Micrurus ibiboboca (Merrem, 1820) and eleven Philodryas nattereri Steindachner, 1870) were collected between January and April of 2005, in the municipality of Crato (07° 14' S and 39° 24' W), State of Ceará, Brazil. Laboratorial analysis of the respiratory tracts of the sampled snakes indicated differences in host infection rates: four individuals of P. nattereri (36.4%) were infected by Cephalobaena tetrapoda Heymons, 1922 (mean infection intensity 1.5 ± 0.28, 1-2) and three specimens (27.3%) by Raillietiella furcocerca (Diesing, 1863) (2.3 ± 1.32, 1-5). Only one individual of M. ibiboboca (25%) was infected by a non-identified species of Raillietiella sp. These are the first data on pentastomid infection in snakes in Northeastern Brazil and both snake species comprise new host records for the pentastomids. The results also indicate that the generalist parasites C. tetrapoda and R. furcocerca share their definitive hosts.

In February-March 1963, during the Equalant Operation for the ICITA program, 476 drift-bottles were released at the equatorial waters off the northern Brazilian coast (01ºS to 09ºN and 043ºW to 053ºW). Thirty-five, bottles were recovered (7,4%). Those were classed in five groups according to their different velocity ranges and areas of recovery (Trinidad Island; Lesser Antilles; Caribbean and Florida area; north Brazil; northeastern Brazil). The recoveries of bottles released within 300 nm off the northern and northeastern coast of Brazil confirmed a strong current along the north and northeast coast in northwestern direction (South Equatorial Current and branches). In late February-early March the bottles showed maximum velocities of this current (3,6 knots). The region off the northern coast of Brazil, between 05ºN and 09ºN up to 050ºW seems to have been under the influence of an eastward component of the surface current in this same period, while at late March this influence appears to have been weaker. In the region from Trinidad Island to Yucatan Peninsula the current seems to be stronger on the northeastern side of the Caribbean Sea.

Restinga forests are plant formations that occur on plains of quaternary sandy deposits along the Brazilian coast. Despite historical reduction of the Restinga forests, little effort has been made to know the butterfly fauna of these areas. This paper is an important contribution to the butterfly’s knowledge, being the second inventory in the Restinga forest of northeastern Brazil. The survey was conducted in the Restinga de Cabedelo National Forest (FLONA de Cabedelo, following the Portuguese abbreviation) and aimed to provide preliminary information on the butterflies richness in this region. A total of 89 butterfly species and 1,503 individuals were recorded at FLONA de Cabedelo. Hesperiidae was the richest family (34 species), followed by Nymphalidae (33) Pieridae (eight), Lycaenidae (seven), Riodinidae (five), and Papilionidae (two). In general, the butterfly fauna of the FLONA de Cabedelo is dominated by species widely distributed and commonly found in open or forested areas in Brazil. Five species are new records in Paraíba state: Calydna sturnula (Geyer), Theope foliorum (Bates), Cogia hassan (Butler), Vehilius inca (Scudder), and Chiothion asychis (Stoll). We suggest carrying out monthly samplings which will certainly increase the list of species herein presented.

SummaryClimatic and ecological factors can influence the parasite load of a host. Variation in rainfall, body size, and sex of the hosts may be related to the abundance of parasites. This study investigated the helminth fauna associated with a population of Norops brasiliensis, together with the effect of host biology (sex, body size, and mass) and variation in rainfall regime on the abundance of helminths. Species of three groups of endoparasites were found (Nematoda, Cestoda, and Trematoda), with nematodes as the most representative taxa with eight species, prevalence of 63.2 %, mean intensity of 4.0 ± 0.58 (1 – 25), and mean abundance of 2.66 ± 0.44 (0 – 25). Nine helminth species are new host records for N. brasiliensis. The nematode Rhabdias sp. had the highest prevalence (53.3 %). There was no significant relationship between abundance of the trematode Mesocoelium monas and host sex or season, although the abundance of this parasite increased significantly with host body size and mass, while abundance of nematodes was related to season and host mass. This study increases the knowledge about the diversity of helminth fauna associated with N. brasiliensis, revealing infection levels of hosts from northeastern Brazil.

The genus Diadema presently consists of seven species, two of which are known from the Brazilian coast: D. antillarum and D. ascensionis. The first is usually known for shallow coastal areas, while the second was apparently restricted to oceanic islands. In February 2011, a dense population of D. ascensionis was observed on the coastal reefs of Praia do Francês (Alagoas State, northeastern Brazil). Five specimens were collected and transported to the laboratory where morphological studies of the test and pedicellariae were conducted. Subsequently, visits were made to scientific collections in order to compare and confirm species identifications. Our observations confirm the presence of tridentate pedicellariae with narrow and strongly curved valves. The axial cavity in the tips of the spines is filled with dense nonreticular tissue. This taxonomic data confirms the occurrence of D. ascensionis in coastal areas. On the coastal reefs of Praia do Francês, animals were observed from the beach to the reef formations about 200 m offshore in areas with a sandy substrate and in reef cavities, usually in clear and well illuminated waters. Solitary individuals or groups of up to 15 individuals formed dense populations in the area. We stress the importance of pedicellariae for the specific identification of the Diadematidae, considering that they are quite constant and reliable at this taxonomic level. Our results demonstrate that D. ascensionis is not restricted to insular environments and that this species may be common in shallow coastal habitats.

The genus Auletta Schmidt, 1970 comprises 14 valid species, with six known from the Atlantic Ocean. The genus was previously recorded for the Brazilian coast only in 1967 from surveys in Pernambuco State. The present paper describes two new Auletta from Northeastern Brazil. Auletta akaroa sp. nov. is from Alagoas State and it has a stalked tubular shape and small sinuous styles and strongyles. Auletta laboreli sp. nov. was found in Pernambuco State and it is a sponge with a cylindrical and cavernous body composed of styles with blunt and telescopic tips and sinuous strongyles. Both new species were compared with the other valid species of Auletta. The spicule complement and external morphology of the new species are discussed.
