Remarks: The incapacity to outline the title Euclymene as symbolizing a phylogenetic speculation is owing the actuality that the taxon is at present presumed paraphyletic there are no synapomorphies now regarded (cf. Table I).

A potential phylogenetic analysis involving associates of Euclymene species will be demanded to take care of this problem. Euclymene vidali sp. nov.

07″ S 34°56’05. ” W). Definition: A distinct hypothesis, accounting for the adhering to figures: presence of 23 chaetigers, cephalic plate with smooth posterior margin, and serrate capillary chaetae on chaetiger 9 arranged as dense bundle.

Hypothetically, each and every of these people arose amongst associates of an ancestral population, finally turning out to be fastened, ensuing in individuals noticed in the present. Description of adult semaphoronts: The holotype is a total specimen, size fifty mm, one.

Paratypes 48‒62 mm extended, one. mm extensive. System cylindrical 23 chaetigers, a single pre-pygidial achaetous section, a single thinner callus ring, pygidial funnel. Anterior finish with oval cephalic plate bordered by very well-produced cephalic rim.

Cephalic rim clean, with two deep lateral notches and 1 posterior notch. Prostomium broadly rounded, forming a little bit arched keel about ten purple-brown ventrolateral ocelli. Nuchal grooves parallel, extending by way of three-quarters of cephalic plate size. Mouth under prostomium, with wrinkled decreased lip. Proboscis a clean eversible sac (Figs. Chaetigers 1–7 varying from one.

mm extended, one. Chaetigers 8–9 two instances longer than anterior chaetigers chaetigers 10–16 3 occasions more time than initial chaetiger posterior chaetigers reducing in size. Notochaetae arise from depressions neurochaetae task immediately from system wall on anterior fifty percent of each segment ( Fig. Remaining chaetigers with compact raised notopodia and conspicuous neuropodial tori. Notopodia of chaetigers 1–23 with fascicles of extended, fantastic capillary chaetae, each individual with connected microalgal filaments. Notochaetae of all chaetigers with posterior row of long, sheathed capillaries, and anterior row of shorter modified capillaries (Figs.

These chaetae have a brief base and are of 3 kinds: limbate spinose modified serrate (Figs. Chaetae on chaetiger nine arranged in dense bundle ( Fig. Neuropodia of chaetigers 1–3 every with one acicular hook, with little denticles above main fang (Figs. Posterior to chaetiger 3, neuropodia with row of rostrate hooks, present to chaetiger 23 (Figs. Hook rows arranged perpendicular to system wall, with long, curved posterior shaft, and prominent manubrium on posterior half. Neuropodial tori with variable number of rostrate hooks (four: 11, 5: 15, six: 22) ( Figs. Pre-pygidial phase about one particular half duration of very last chaetiger, with minimized torus at posterior finish. Unique callus ring in posterior region of segment ( Fig. Pygidial funnel prolonged posteriorly, bearing 22 subconical anal cirri of somewhat variable duration (paratypes with 19‒27) midventral cirrus two occasions for a longer time than other cirri.
