“…Distribution. Scyramathia hertwigi is known from its type locality, off Cape Point and Agulhas Bank, South Africa, and Namibia, between 250 and 622 m [22,85], as well as from areas of the south Atlantic along the African coast. The first record in the waters of Guinea-Bissau was made by Muñoz et al [86] at a depth of 500 m. It is also known along the southwesternmost edge of the Indian Ocean.…”

The updated checklist of the marine crabs of Guinea-Bissau presented in this work is the result of consolidating decades of research, ongoing systematic revisions of the regional carcinofauna, and the inclusion of new records. DNA markers and morphological analyses for accurate identifications are integrated. Sixty-one species are mentioned in this list after reviewing specimens from scientific collections and literature. Of these 61 species listed, the presence of 51 species in Guinea-Bissau is confirmed, and 21 are reported for the first time in the area. A total of 98 sequences were obtained from 41 species (51 of 16S for 38 species and 47 of COI for 35 species), and 48 sequences (24 of 16S and 24 of COI) were the first ones obtained for 29 species. The maximum or minimum bathymetric range is expanded by 16 species, and for other six species, a color description is provided for the first time. Merocryptus obsoletus is synonymized as Merocryptus boletifer. The present study will be a useful baseline for gathering further ecological information about globally important marine taxa, not only in Guinea-Bissau but about African brachyurans in general.

The macrofauna associated to the bamboo coral Isidella elongata: to what extent the impact on isideidae affects diversification of deep-sea fauna

et al. 2022

Macrofauna associated with the bamboo coral Isidella elongata was analysed in the Balearic Basin at depths of 697–1308 m. The diversity of associated macrofauna and the specific associations identified depended on different morphological characteristics of colonies, such as height or density of rami. Species associated with Isidella consisted mainly of sessile fauna, such as cnidarians (the actinian Amphianthus dornhii and the solitary coral Desmophyllum dianthus) and cirripeds (Gibossaverruca sp.). The strongest relationship (commensalism) occurred for the Pontogeneiidae amphipod Dautzenbergia megacheir, living attached to colonies of Isidella and represented by all population stages from adult (oostegal) females and males to juveniles. Species-coral relationships between Dautzenbergia and bamboo corals (Isididae) are plausible. Dautzenbergia spp. showed morphological differences between Atlantic (described by Walker 1897 as “eyes wanting”) and Mediterranean (with well-developed reddish eyes) specimens. This would suggest diversification of this genus, as has been recently suggested for Pleustidae associated with deep gorgonians. The diversity of the macrofaunal community associated with I. elongata was higher in the most mature (larger colonies with higher density) fields found NW of Mallorca, with higher colonies than in other parts of the Mediterranean. This was the only site where Gibossaverruca sp. (a first Mediterranean faunal record) and D. dianthus were collected. These complex associations between macrofauna and deep-water corals may provide arguments to protect these fragile ecosystems as a source of faunal diversity and diversification.

The majoid genus LibiniaLeach, 1815 currently contains 10 valid species, all inhabiting mostly tropical waters in the Western Hemisphere. Three occur in the Eastern Pacific (L. mexicanaRathbun, 1892, L. peruanaGarth & Méndez, 1983, L. setosaLockington, 1877) and seven in the Western Atlantic (L. cavirostrisChace, 1942, L. dubia H. Milne Edwards, 1834, L. emarginataLeach, 1815, L. erinacea (A. Milne-Edwards, 1878), L. ferreiraeBrito Capello, 1871, L. rhomboideaStreets, 1870, L. spinosa Guérin, 1832). The genus is revised using morphological data and the examination of the type series. Sister taxa from the Eastern Pacific are morphologically distinguishable from their Western Atlantic congeners. The present revision recognizes the 10 species, adding new diagnoses and a key to their identification.
