New records of occurrence for four species of lampriform fishes (Teleostei: Lampriformes; Desmodema polystictum, Regalecus russelii, Trachipterus fukuzakii and Zu cristatus) poorly known or previously unknown for the Pacific coast of lower Central America (Costa Rica-Panama) are herein reported. Museum specimens supporting such records are characterized and described. Comparative morphometric and meristic data on other collections and species of lampriforms, as well as distributional information, are provided and discussed. Diversity, taxonomy and distribution of the eastern Pacific species of the order also are briefly discussed. Finally, a key to the eastern Pacific species of the Lampriformes, based on our research and data available in the literature, is presented.

The recently described alpheid genus Triacanthoneus Anker, 2010 is reassessed based on new material from the Pacific and Caribbean coasts of Panama, and the southern Gulf of Mexico. Salmoneus armatus Anker, 2010 is tentatively transferred to Triacanthoneus and the latter genus is redefined. A new eastern Pacific species of Triacanthoneus is described based on a single specimen collected by scuba diving off Coiba Island on the Pacific coast of Panama. Triacanthoneus blanca sp. nov. is closely related to its only eastern Pacific congener, T. pacificus Anker, 2010, which is reported for the first time from the Las Perlas Islands in the Gulf of Panama. Morphological variation in T. toro Anker, 2010 is discussed on the basis of new topotypical material from Bocas del Toro, Panama, and a single specimen tentatively reported as T. cf. toro from Sisal, Mexico. An identification key to the seven currently known species of Triacanthoneus, with updated distributional and ecological information, as well as high-resolution colour photographs of four species are also provided.

To date, the poecilosclerid sponge genus Pozziella Topsent, 1896 was represented by two species: Pozziella clavisepta Topsent, 1896 and Pozziella aperta (Topsent, 1920), which are presently redescribed. During the campaign SO 144-3a of the project PAGANINI in the Pacific Ocean between the Galapagos Archipelago and Central America, three new species were recovered and are described here: Pozziella cerilla sp. nov., Pozziella neuhausi sp. nov. and Pozziella lueteri sp. nov. The present study led to a revision of the genus and an attempt to resolve the relationships between the species, based on the likeness of spicule complements and biometric characters. A similarity analysis revealed that Atlantic and Pacific species clustered separately. In addition, a key to all species of the genus based on spicular characters is provided.

New World species of the genus Incisitermes Krishna, 1961 range from California to Peru.  The soldier of this genus is notable for the incised anterior margin of the pronotum and the elongated third antennal article.  I report the broad occurrence of Incisitermes platycephalus (Light, 1933) from extreme southern Mexico to the Pacific coast of Nicaragua. Incisitermes nigritus (Snyder, 1946) from Guatemala is a junior synonym of I. platycephalus.  Among Incisitermes, I.  platycephalus is characterized by its small size, dark imago, and dorsoventrally compressed soldier head capsule.

A New Species

A new species of porcelain crab, Petrolisthes lazarus sp. nov., is described from the Pacific coast of Panama, based on two female specimens. The new species is morphologically most similar to another eastern Pacific species, P. crenulatus Lockington, 1878, especially in the general configuration of the carapace, chelipeds and ambulatory legs. However, P. lazarus sp. nov. can be separated from P. crenulatus by the differences in the proportions of the carapace, the shape of the frontal region of the carapace, and the setation pattern of the cheliped. In addition, P. lazarus sp. nov. and P. crenulatus appear to be allopatric, the latter species presently being known only from Mexico. Among other eastern Pacific taxa, P. lazarus sp. nov. may have some affinities with P. ortmanni Nobili, 1901 and P. lewisi (Glassell, 1936), from which it can be easily distinguished by the chelipeds lacking a dense field of setae on the outer (lateral) surface of the palm and with different proportions of some articles, especially the carpus. The four species can also be distinguished from each other by their diagnostic, although somewhat variable colour patterns.

A New Species

The family Chrysopetalidae has been poorly studied from the Pacific coast of Mexico compared to other families. Specifically from the southern Mexican Pacific, only two species of the family have been recorded in previous studies, Chrysopetalum occidentale and Paleanotus chrysolepis. In this study 311 specimens were revised, and nine species, belonging to six genera were found. Eight of these species are new records from the southern Mexican Pacific coast: Arichlidon watsonae n. sp., Bhawania cf. goodei, Chrysopetalum elegantoides, C. maculata, Hyalopale sp., Paleaequor psamathe, Paleanotus bellis and P. purpurea. A new species is also described, Arichlidon watsonae n. sp., which is characterized by the curved tips blades of the falcigers and their small and ovoid palps. Additionally, the genera Arichlidon and Hyalopale are recorded by first time from the Tropical Eastern Pacific.

Alpheid Shrimp

The present study deals with five species of the alpheid shrimp genus Salmoneus Holthuis, 1955 from the tropical eastern Pacific. One of them is new to science and is described as Salmoneus tiburon sp. nov. The new species is presently known only from the Las Perlas Archipelago in Panama and can be distinguished from all other congeners by the dentition on the cutting edges of the major chela, with some dactylar teeth reminiscent of shark teeth. It is also one of the largest species of the genus, with the carapace length of both type specimens surpassing 8.0 mm. Salmoneus serratidigitus (Coutière, 1897), a species with an ample distribution across the Indo-Pacific, is recorded for the first time from the Pacific coast of Panama and is confirmed from Colombia. Salmoneus malagensis Anker & Lazarus, 2015, previously known only from Bahía Málaga in Colombia, is recorded from Panama’s Azuero Peninsula. The remaining two species, S. excavatus Anker, 2011 and S. alvarezi Anker & Lazarus, 2015, are recorded regionally from Las Perlas Archipelago in Panama and Playa Tarcoles in Costa Rica, both for the first time since their original descriptions. An identification key to the five currently known eastern Pacific species of Salmoneus is provided. However, several immature and/or incomplete specimens herein preliminarily reported as Salmoneus spp., as well photographic records from southern California, USA, indicate the presence of further undescribed species in the eastern Pacific.
