The known cicada fauna of the Republic of Trinidad and Tobago is identified. Calyria hyperochelabrys n. sp., Carineta trinidadensis n. sp., and Herrera grammosticta n. sp. are described as new. The first records of Fidicinoides descampsi Boulard & Martinelli, 1996, Proarna hilaris (Germar, 1834), Guyalna bogotana (Distant, 1892a), Majeorona aper (Walker, 1850), Taphura boulardi Sanborn, 2011a, Carineta matura Distant, 1892b, and Herrera nigropercula Sanborn, 2020b are provided. The first reports for the genera Guyalna Boulard & Martinelli, 1996, Majeorona Distant, 1905d, Calyria Stål, 1862, Carineta Amyot & Audinet-Serville, 1843 and Herrera Distant, 1905c and the tribes Parnisini Distant, 1905e and Carinetini Distant, 1905c are represented by the records for the new species and new records. The first records of Proarna hilaris (Germar, 1830) for Anegada, Antigua, Grenada, Canoun Island, Mayreau Island and Union Island in the Grenadines, Little St. James, Little Thatch Island, Montserrat, Mosquito Island, and St. Kitts, Proarna palisoti (Metcalf, 1963a) for Navarro Island, Majeorona aper (Walker, 1850) for Grenada, and Ariasa albimaculosa Sanborn, 2016c for Bonaire are provided to increase the known distributions of these species and the Caribbean fauna. The currently known cicada fauna for Trinidad is increased here to 15 species representing ten genera, four tribes and two subfamilies. Only Quesada gigas (Olivier, 1790) is known currently from Tobago.

ABSTRACT As they spend most of their time buried in the substrate and are not a fishery resource, heterenchelyids are seldom seen. These eels are characterized by their greatly reduced eyes, which are covered by semi-transparent skin, the absence of a pectoral fin or lateral line, and no pores on the head or body. Pythonichthys sanguineus is a particularly poorly-known species, with only eight scientific records from Cuba, Puerto Rico, Colombia, Venezuela, Guyana, and Suriname. The present study is based on six adult specimens of P. sanguineus captured by vessels of the shrimp trawling fleet along the northern Brazilian coast, in the vicinity of the Amazon Reef. We provide meristic, morphometric and DNA barcoding data. These findings provide insights into the distribution of the species off the northern Brazilian coast and contribute to the discussion about the southern limit of the Greater Caribbean fauna.

In the subfossil, elevated coral reefs which form the Islas del Rosario, southwest of Cartagena (Colombia), 51 species of Gastropoda and 22 species of Pelecypoda were collected, all of them belonging to the recent Caribbean fauna. Even fragile shells could be obtained completely intact, which indicates the little age of these cliffs, as it has been estimated by two authors less than 10 000 years. An interesting species secured is Conus granulatus.

We report the discovery of an extremely rich, previously undescribed Caribbean late Miocene to early Pliocene ichthyofauna represented by one hundred forty species of elasmobranchs and teleosteans from the Cubagua Formation, northeastern Venezuela. The fauna exhibits significant ecological differences compared with common neritic Caribbean Neogene assemblages. The bathymetric distributions of taxa, based on living counterparts, ranges from 0 to 100 m depth. The exceptional co-occurrence of deep water (epipelagic, mesopelagic and benthopelagic), and shallow water (neritic) taxa is best interpreted as the consequence of ocean upwelling in the proximity to the deep-water Cariaco Trench. Patterns of predator and prey are established and corroborate upwelling. Special remarks are made regarding previously unknown late Miocene to early Pliocene Caribbean ichthyofaunas, the absence or rarity of reported fossil taxa in the Recent Caribbean fauna, and a paleo- upwelling indicator (Lampadena jacksoninew species).
