diagnosis
DIAGNOSIS. — Phyllodocids with prostomium with two oblong tapered lateral antennae, median antenna often reduced into a nuchal papilla. Four pairs of oblong tapered tentacular cirri. Dorsal cirrophore without acicula; supracicular lobe usually blunt, as long as subacicular one; ventral cirri usually medially widened. Pharynx with two regions, basal region with large papillae, usually arranged in longitudinal rows, dorsal and ventral areas smooth (without papillae).
discussion
KEY TO SPECIES OF ANAITIDES CZERNIAVSKY, 1882 REMARKS Pleijel (1993 b: 295, fig 1 G) regarded P. citrina Malmgren, 1865 as incertae sedis especially because it has less than 6 lateral rows of papillae per side on its pharynx basal region. More than six rows were documented for one Anaitides species (Day 1973: 22), as well as non-regular lateral rows for several other species (Hartmann- Schröder 1965 b: 86; Gathof 1984: 19.33), and differences in the number of papillae per row (O’Connor 1987: 312). Further, in the new species described below, A. albengai n. sp., variations in the number of lateral rows were noted, and often in the same specimen there was a different number of rows along the left or the right side. However, the presence of smooth areas along dorsal and ventral surfaces are more regular and this explains why the midventral smooth surface is diagnostic, whereas the number of lateral rows is not. Consequently, P. citrina is included in Anaitides as indicated by Uschakov (1972: 130), and after the redescriptions by Pleijel (1988: 143), Pleijel & Dales (1991: 78), and Pleijel (1993 a: 35). For the key below, the descriptions or redescriptions were used to key out the species; sometimes, more than one morphological pattern has received the same name, and this explains why the same species name may be reached in two or more alternatives. They are included and might mean problematic records deserving further study. Likewise, the distribution area is incorporated but it does not mean the full distribution of the species. Anaitides catenula (Verrill, 1873), A. groenlandica orientalis (Zachs, 1933), and A. heterocirra Chamberlin, 1919 were not included because of a lack of information in the original descriptions.
distribution
DISTRIBUTION. — The species of Anaitides have been described from shallow-water localities in tropical, temperate and polar seas.
etymology
ETYMOLOGY. — Anaitis, Anahita or Artemis Anaitis, is the love Godess for Armenians and Persians (Brosius 1998). Czerniavsky (1882) proposed several new phyllodocid genera, and for some of them followed Théel (1879) who proposed Mystides after Mysta. Anaitides Czerniavsky (1882: 158) was derived from Anaitis Malmgren, 1865. The latter was preoccupied by Anaitis Duponchel, 1829 (Lepidoptera) and Anaitis Roemer, 1857 (Mollusca), and was renamed Paranaitis by Southern (1914). GENDER. — Feminine. After the code (ICZN 1999, Art. 30.1.4.4), the suffix – ides “ is to be treated as masculine unless its author, when establishing the name, stated it had another gender or treated it as such by combining it with an adjectival species-group name in another gender form. ” Czerniavsky (1882: 159) listed the species for his new genus, newly transferred from Phyllodoce (feminine) and made no modifications for their corresponding suffixes, thus implying he regarded his new genus-name as having a feminine gender.
