    A new species and first record of Dracoderes (Kinorhyncha: Allomalorhagida: Dracoderidae) from American waters, with an identification key of the genus
    (Zoologischer Anzeiger, 2019) Cepeda Gómez, Diego; Pardos Martínez, Fernando; Sánchez Santos, Nuria
    A new species of Dracoderes, Daracoderes spyro sp. nov., is described from Hispaniola Island (Caribbean Sea), and represents the first record of this genus in American waters. The new species is distinguished from its congeners by the presence of lateroventral spines on segments 3e4 and 6e9, lateral accessory spines on segment 5, lateroventral tubes on segments 2, 5 and 10, and laterodorsal tubes on segment 8. Additionally, a dichotomous key to the species level for the genus Dracoderes is included.

    First report of the family Zelinkaderidae (Kinorhyncha: Cyclorhagida)for the Caribbean Sea, with the description of a new species of Triodontoderes Sørensen & Rho, 2009 and an identification key for the family
    (Zoologischer Anzeiger, 2019) Cepeda Gómez, Diego; Sánchez Santos, Nuria; Pardos Martínez, Fernando
    A new species of Kinorhyncha, Triodontoderes lagahoo sp. nov., is described from Tobago Island, Caribbean Sea (western Atlantic Ocean) from a coastal, sandy habitat using both light and scanning electron microscopy. The species is characterized by the presence of middorsal acicular spines on segments 1e11 (that on segment 10 crenulated in males), laterodorsal crenulated spines on segment 10 only in males, lateroventral acicular spines on segments 3e4 and 6e8 (lateroventral spines also on segment 10 in females), lateroventral cuspidate spines on segments 5 and 9, lateral accessory acicular spines on segments 5 and 9, lateral accessory cuspidate spines on segment 8, ventrolateral acicular spines on segment 2 and ventrolateral cuspidate spines on segment 2. Females furthermore possess short papillae in ventrolateral position on segment 8 and ventromedial position on segment 9. The absence of cuspidate spines in lateral accessory position on segment 6 easily distinguishes T. lagahoo sp. nov. from the single known congener, Triodontoderes anulap. Moreover, also the arrangement of female papillae and sensory spots differ between the species. The finding of a new species of Triodontoderes in the Caribbean Sea is the first report of the genus for American waters and the Atlantic Ocean since its original description. Additionally, a dichotomous key for identification of the family Zelinkaderidae to species level, as well as systematic remarks on some morphological characters of the new species are included herein.

    Kinorhyncha from the Caribbean, with the description of two new species from Puerto Rico and Barbados
    (Zoologischer Anzeiger, 2019) Cepeda Gómez, Diego; Pardos Martínez, Fernando; Sánchez Santos, Nuria
    Two new kinorhynch species from Puerto Rico (Greater Antilles) and Barbados (Lesser Antilles) are described herein from Dr R. P. Higgins' unexamined Caribbean meiofaunal samples, which have been stored in the Smithsonian Institution collections. The species from Puerto Rico, Cristaphyes cornifrons sp. nov., belongs to the class Allomalorhagida, whereas the species from Barbados, Echinoderes barbadensis sp. nov., belongs to the class Cyclorhagida. C. cornifrons sp. nov. is easily distinguished from most of its congeners by the presence of lateral terminal spines and the absence of male, sexually dimorphic, ventromedial tubes on segment 2, as only other two species of the genus lack these features. Of these, C. cornifrons sp. nov. may be easily differentiated by its pattern of paradorsal, ventrolateral and ventromedial setae. E. barbadensis sp. nov. is unique among its congeners by the combined presence of middorsal spines on segments 4e8, lateroventral spines on segments 6e9, lateral accessory tubes on segment 8, lateroventral tubes on segment 5, ventrolateral tubes on segment 2 and type 2 glandular cell outlets in subdorsal position on segment 2 and in midlateral position on segment 4.
