Neogene decapod crustaceans from the Caribbean of Colombia
Boletin de la Sociedad Geologica Mexicana, 2017
An abundant and diverse assemblage of decapod crustaceans from the Neogene (Miocene to Pliocene) from the Las Perdices and Tubará formations in San Jacinto Fold Belt (Colombian Caribbean) is here reported. Found in shallow marine and paralic sediments, specimens of the following taxa are identified: Callianassa sp., Neocallichirus scotti (Brown and Pilsbry, 1913), Glypturus toulai (Rathbun, 1919), Petrochirus bouvieri Rathbun, 1919, Hepatus lineatinus Collins and Todd in Todd and Collins, 2005, Palaeopinixa perornata Collins and Morris, 1976, Persephona enigmatica Collins and Todd in Todd and Collins, 2005, Microphrys sp., Necronectes proavitus (Rathbun, 1918), Scylla sp., Euphylax maculatus Collins and Todd in Todd and Collins, 2005, and Eurytium sp. All of these taxa indicate a correlation with other Caribbean crustaceans from the Neogene, mainly of Panama, Costa Rica and Venezuela. The facies association, and decapod assemblage suggest shallow marine environments for the Neogene units of this area of Caribbean coast of Colombia.

In this contribution a new species of the land crab genus Gecarcinus Leach, 1814, from the Neotropical Pacific coast of South America is described and illustrated. In addition to its unique body color, Gecarcinus nobilii sp. n. is distinguished from congeners by a distinctly wider carapace front and differences in the shape of the infraorbital margin. The new species is not isolated from Gecarcinus populations from the Pacific coast of Central America by an insurmountable geographic barrier. Considering the closure of the Panamanian Isthmus as a calibration point for morphological divergence between the trans-isthmian mainland populations of Gecarcinus, the virtual lack of morphological differentiation (other than color) between them and the distinctness of G. nobilii sp. n. suggests that G. nobilii sp. n. evolved from a common ancestor before the Isthmus closed.
THE FIRST RECORD OF THE EXTINCT CRAB NECRONECTES (DECAPODA: PORTUNIDAE) IN VENEZUELA
– The Urumaco Formation is well known for being fossiliferous, including both vertebrate and invertebrate assemblages. Despite extensive fi eld work over the past years the decapod fauna from the Urumaco Formation still remains poorly known. In the present work we report for the fi rst time the presence of the extinct portunid crab, Necronectes proavitus Rathbun from Venezuela, based on a well-preserved cast of the carapace recovered from the late Miocene Urumaco Formation. This record signifi cantly contributes to a better understanding of both the biochronology and biogeography of Necronectes in the Caribbean region. N. proavitus is now known from the early to late Miocene of Puerto Rico, Trinidad, Panama, Venezuela and Brazil.

We report herein the euryplacid crab Sotoplax robertsi, previously known only from the type locality (Gulf of Mexico, 28º30'N, 84º58'W), off the east coast of Brazil (states of Bahia and Espírito Santo, 13°54'14"S, 39°00'34"W and 20º44'S, 40º25'W, respectively). This is the first record from the South Atlantic Ocean, and considerably extends the known geographical range of this species. We provide information on the morphology of the male, and the first description of the female.

Calyptraeotheres hernandezi is described from off Cubagua Island, Caribbean Sea, Venezuela. The new species resembles C. granti from the eastern Pacific, with both taxa possessing a third maxilliped with an endopod palp of only two segments, i.e., with the dactylus missing, and the exopod with a thin and unsegmented flagellum. The new Atlantic species differs in the female having eyes that are visible from dorsal view, the propodi of the walking legs having subparallel margins, and the ventral margin of the pollex bearing a small fringe of setae. In contrast, the Pacific limpet crab C. granti has the eyes hidden from the dorsal perspective, the margin of the propodus of the walking legs tapered distally, and the ventral margin of the pollex with a well-developed fringe of setae. The austral species C. garthi and C. politus (Smith, 1870) can be separated from the former two species by their third maxilliped having a rounded and minute dactylus that is inserted subdistally on the ventral margin of propodus. The new species inhabits the West Indian gastropod Crucibulum auricula (Gmelin).
Additions to the Scaphopod Fauna (Mollusca: Scaphopoda) of the Colombian Caribbean
Caribbean Journal of Science, 2005
Twelve scaphopods species were obtained during the "Invemar-Macrofauna" trawling campaigns along the continental shelf and slope of the Colombian Caribbean (70-500 m depth). Of these six (Dentalium gouldii, D. laqueatum, Calliodentalium callipeplum, Entalina platamodes, Gadila watsoni, and Compressidens pressum) were recorded for the first time from southern Caribbean waters. In addition, the genus Striocadulus was recorded for the first time in Atlantic waters. With the new records the number of scaphopods for the area increased to 23 species.
