Podarke golikovi sp. n. (fig. 5, 1-4)
The species is named in the honour of the famous hydrobiologist and polar researcher, my teacher and friend Alexandr Nikolaevitsj Golikov, together with whom this material was gathered.
Material: Island of Malij Ljachovskij, cape Vajgatsj, depth 1.8 m. lightly-sandy ooze.
Holotype deposited at the Zoological Institute Academy of Sciences SSSR (Leningrad) on Nº 1/46758
Very small worm, represented by a frontal fragment. Though some specimens with good preservation were discovered at Franz Josefs Land, that also made it possible to give the description of this species.
fig 5. Podarke golikovi. 1 - frontal part of body, 2 - parapodia of Xth segment, 3 - ventral seta from the upper and the lower parts of a bundle, 4 - central ventral seta.
The prostomium has a rectangular shape, its width is slightly bigger than its length. It has 4 eyes, 3 similar antenna and a pair of two-segmented palps. The cephalic tentacles are pointed, but the palps have blunt ends. The frontal pair of eyes is somewhat larger than those at the back and are placed wider. The 3 almost fused peristomial segments bear 6 pair of pseudo-segmented tentacular cirri, of which the dorsal are longer than the ventral, and the distal longer than the frontal (fig 5: 1). First setae appear on the first segment. The proboscis is without teeth and armed on the oral edge with 20 digitiform papillae. Parapodia biramous, on which the dorsal ramus is lesser than the ventral, but one may hardly say that it is reduced (fig 5: 2). The dorsal cirrus do not exceed the length of the dorsal setae, it is pseudo-segmented with 3-4 constrictions and a small cirrophor. The ventral cirrus is smooth, slightly swollen. Dorsal setae have a long capilliform tip and are vaguely toothed on the edge. Ventral setae are compound, with long and exact toothing on the cutting edge of the two-toothed segment, of which the longest is directed from the central part of the bundle (fig 5: 3,4). The character of colouration is dark striation, connecting the distal pair of eyes, and 2 wide longitudinal strie, going along the dorsum over the dorsal cirri.
Taxonomical observations. Fundamental taxonomical characters - the cirriform appendages of the head, the equipment of the proboscis, the character of the parapodia and appearance of setae on the peristomial segments of the new species is a part of a group of species, united with a specific name Podarke Ehlers, 1864. However it is at the same time needed to point out the profound artificialness of the collection of this genus, but since we do not put ourselves to the task of a revision of the given group of worms, we limit ourselves to only a detailed description and a comparison with the closest species of the genus Podarke. Such that, closest to the place of finding is the species P. pugettensis Johnson, 1901 from which our species differs well in developed notopodia and the distinct expression of pseudo-segmentation on tentacular and dorsal cirri. Actually these characters makes it fundamentally different also from the other species of this genus, which many researchers consider as a synonym to the genus Ophiodromus.
Ecology. In our material were only one specimen caught, with a body width of 0.5 mm., in length the fragment was 5.5 mm. which was sexually mature and had between the podial region from 3-4 white eggs with a diameter of 0.1 mm. The worm was caught on 1.8 m in light oozy sand in the biocoenosis Rhizomolgula globularis, where the biomass of the latter was 0.004±0.001 g/m2 and the density of inhabitants was no more than 1 specimen on 1 m2.
Distribution. Franz-Josefs Land and the New Siberian Isles, on the very upper part of the sublittoral.
