| The family Ammotheidae is the most diversified group of the class Pycnogonida, with 297 species described in 20 genera. Its monophyly and intergeneric relationships have been highly debated in previous studies. Here, we investigated the phylogeny of Ammotheidae using specimens from poorly studied areas. We sequenced the mitochondrial gene encoding the first subunit of cytochrome c oxidase (CO1) from 104 specimens. The complete nuclear 18S rRNA gene was sequenced from a selection of 80 taxa to provide further phylogenetic signal. The base composition in CO1 shows a higher heterogeneity in Ammotheidae than in other families, which may explain their apparent polyphyly in the CO1 tree. Although deeper nodes of the tree receive no statistical support,... |

| This work deals with feeding tests performed in laboratory with Pantopoda species, Tanystylum isabellae Marcus, 1940 and Anoplodactylus stictus Marcus, 1940. Animals (alive and dead) and vegetable foods were offered to males without eggs, males with eggs, females and juveniles Pantopoda. Of the 13 types of food offered to the animals only Sertularia Linnaeus, 1758 (Hydrozoa). Amathia distans Busk, 1886 (Bryozoa), Hyale media (Dana, 1853) (Crustacea, Gammaridea), Caprella danilevskii Czerniavski, 1868 (Crustacea-Caprellidae), Artemia salina Leach, 1812 (Crustacea, Anostraca) e Perna perna (Linné, 1758) (Bivalvia, Mytilidae) were actually eaten. The macroalgae Sargassum C. Agardh, 1820; Padina Adanson, 1763; Chaetomorpha Kützing, 1845 and Ulva Linnaeus.... |
