This study presents the inventory of sea spiders (Pycnogonida) sampled during the Madibenthos Expedition in Martinique (West Indies). Species were discriminated leaning on morphological and molecular data. A total of 761 specimens are classified in 72 species, 16 genera and nine families. Thirteen new species are described: Ammothella dirbergi sp. nov., A. krappi sp. nov., Tanystylum boucheti sp. nov., T. ingrallis sp. nov., Ascorhynchus iguanarum sp. nov., Eurycyde kaiouti sp. nov., Nymphon dorlis sp. nov., N. ludovici sp. nov., N. martinicum sp. nov., N. timons sp. nov., Anoplodactylus madibenthos sp. nov., Pycnogonum cesairei sp. nov. and Rhynchothorax sidereus sp. nov. We describe a neotype for Anoplodactylus micros Bourdillon, 1955 from the type locality. Martinique now includes 79 species of sea spiders, mostly endemic to the Tropical Northwestern Atlantic, cosmopolitan or shared with the South America Atlantic coast. Some species are potentially introduced. However, our knowledge of the distribution of species found in Martinique is probably biased by the scarcity of diagnostic morphological characters. Also, nine potentially cryptic species (discriminated on genetic data alone), are identified, shedding light on the overlooked diversity of sea spiders in the Tropical Northwestern Atlantic. Therefore, we call for a more widespread use of barcoding in sea spiders.
Thirteen new fossil eucnemid taxa (Coleoptera: Elateroidea) are described from amber deposits excavated from the vicinity of Santiago, Dominican Republic. Two new genera, Mioxylobius and Paleoquirsfeldia are described. The following 13 new species are described from Dominican amber: Mioxylobius bicolor, Balistica serrulata, Paleoquirsfeldia epicrana, Dyscharachthis dominicana, Idiotarsus poinari, Euryptychus antilliensis, Euryptychus hispaniolus, Plesiofornax caribica, Fornax dominicensis, Fornax serropalpoides, Dromaeolus argenteus, Nematodes miocenensis and Nematodes thoracicus. Each new species are both diagnosed and illustrated. Calyptocerus Guérin-Méneville and Lissantauga Poinar are shown to be congeneic, resulting in a new combination: Calyptocerus epicranis (Poinar, 2013). Summaries of fossil eucnemid discoveries, highlighting differing hypothesis of prehistoric Caribbean island formations/speciation, accounts of ancient Dominican Republic environmental conditions and Dominican Republic amber are provided.

The West Indian genus Onychotillus Chapin (Coleoptera: Cleridae: Tillinae) is revised and includes O. androwi Opitz, new species, O. apiculus Opitz, new species, O. cinctipennis (Chevrolat,1874), O. cubana de Zayas,1988, O. dimidiatus de Zayas,1988, O. lineatus Opitz, new species, O. minutus de Zayas,1988, O. trinitatis de Zayas,1988, O. woodruffi Opitz, new species, and O. vittatus Chapin,1945.
Originally described from Great Guana Cay, Exuma Islands, Bahamas, Choranthus richmondi L. Miller, was also recorded from North Andros Island. Three specimens were collected on South Andros Island, Bahamas, in March 2014, representing a new record for this island. Photographs of adults, a complete diagnosis, genitalia illustrations, and a description of the habitat, nectar sources, and potential hostplant are presented. The male genitalia are illustrated for the fi rst time.
We review the genus Cyclargus Nabokov (Lepidoptera: Lycaenidae) based on detailed comparative analyses of wing patterns, genitalia, and mitochondrial COI DNA barcode sequences, and suggest that Cyclargus is composed of four species: C. thomasi (Clench), C. woodruffi (W. Comstock and Huntington), C. ammon (Lucas), and C. dominica (Möschler). The following new subjective synonyms are proposed: C. erembis Nabokov syn. n. and C. kathleena K. Johnson and Matusik syn. n. are C. thomasi noeli (W. Comstock and Huntington); C. sorpresus K. Johnson and Matusik syn. n. and C. shuturn K. Johnson and Bálint syn. n. are C. ammon; and Cyclargus oualiri Brevignon syn. n. is C. woodruffi. Additionally, we report the discovery of C. thomasi noeli in Cuba (where this taxon was previously confused with C. ammon), report C. ammon from Hispaniola for the first time, and document the widespread sympatry of C. thomasi and C. ammon in the northern Caribbean (including south Florida, Cuba, Cayman Islands, Hispaniola, Lucayan Archipelago). Finally, we provide a provisional synonymic list of Cyclargus taxa, which may serve as a taxonomic framework to assist efforts to conserve the Miami blue (C. thomasi bethunebakeri (W. Comstock and Huntington)), a taxon listed as "Endangered" under the Endangered Species Act in the United States.
