Holotype incomplete with 112 chaetigers, 43.1 mm long, 1.8 mm wide, L10 = 4.4 mm. Body cylindrical, light pink colour in preserved specimen ( Figures 2A View Figure 2 , 5A View Figure 5 ). Prostomium rounded, wider than long. Prostomium (1 mm) longer than peristomium (0.75 mm) with five prostomial appendages one pair of palps, one pair of lateral antennae and a median antenna. Prostomial appendages in a horseshoe pattern, longer than prostomium, similar thickness. Palps shorter than antennae, digitiform, reaching front of chaetiger 1. Antennae tapering, lateral antennae reaching middle of chaetiger 3, median antenna reaching middle of chaetiger 4. Palpophores and ceratophores short, wider than long. Palpostyles and ceratostyles without articulations. Eyes absent. Peristomium cylindrical with distinct rings; anterior ring (0.5 mm) more than twice as long as posterior one (0.2 mm). Peristomial cirri absent.

Maxillary apparatus with five pairs of maxillae. Maxillary formula = 1 + 1; 7 + 6; 6 + 0; 3 + 6; 1 + 1.

Branchiae pectinate, from chaetiger 14 to 25, always longer than dorsal cirri; eight filaments at first one, up to 15 at chaetiger 23, stems tapering; filaments tapering, similar in size and thickness.

Dorsal cirri Anterior cirri cylindrical and elongated, Anterior cirri cylindrical, inflated First two cirri cylindrical and small, longer than parapodium after slightly, elongated through the elongated through the median part, chaetiger 3, twice long as after branchial chaetigers, thin and become thinner and tapering on the chaetiger 7, tapering, thin, as long as tapering on the postbranchial branchial chaetigers, median cirri branchial filaments on branchial chaetigers thin and filament shaped, tapering chaetigers, median cirri thin-filament and small on the posterior shaped twice as long as parapodium, parapodium tapering and spindle shaped on posterior parapodium

Ventral cirri First two cirri conical and small, leaf- Anterior cirri conical, small; become First cirri conical, small and basally shaped after chaetiger 2, median shorter at the branchial chaetigers, inflated, decreased on the median ventral cirri triangular and flattened; reducing and swollen basally at the part of the body pad-like shaped, reduced to small notches in posterior postbranchial chaetigers with thin dramatically decreased through the parapodium tips posterior, like small conical bulge with tapering tips

Limbate chaetae Smooth, 10–15 per parapodium Smooth, long 6–8 per parapodium Smooth, long 18–20 per parapodium on anterior; 5–10 on posterior

Pectinate chaetae Marginal tooth longer, around 7 Marginal tooth long, around 8–10 long Marginal tooth long, around 8–9 long tapering teeth. Thinner than other coarse teeth with filament-like coarse teeth with filament-like species have extensions. Two or three per extensions. Two or three per parapodium parapodium

Compound falciger Bidentate, both teeth facing laterally, Absent Absent proximal teeth triangular, margin of distal part slightly serrated, not present all chaetigers, present at posterior chaetigers, one per parapodium


Anterior dorsal cirri cylindrical, longer than parapodia after chaetiger 3 to chaetiger 7, twice as long as parapodia after chaetiger 7 to chaetiger 24; elongated and spindle shaped in median parapodia (between chaetigers 25 and 46), tapering and filament shaped in posterior parapodium (between chaetigers 47 and 112). First two ventral cirri small, and conical; leaf shaped after chaetiger 2 to chaetiger 25; triangular and flattened from chaetiger 26 to chaetiger 46; reduced to small notches in posterior parapodia. Anterior ventral cirri swollen basally compared with posterior ones.

Prechaetal lobes inconspicuous, transverse fold in all chaetigers. Postchaetal lobes conical and longer than prechaetal lobes in anterior chaetigers, decreasing gradually until becoming inconspicuous ( Figure 3A–C View Figure 3 ).

Supra-acicular chaetae with 10–15 limbate in anterior chaetigers, two to five in posterior ones. Three to five pectinate chaetae in all chaetigers except anterior ones. Subacicular chaetae with 20–25 compound spinigers in anterior chaetigers; five to ten compound spinigers and one compound bidentate falciger in posterior ones. Limbate chaetae slender, marginally smooth ( Figure 2B View Figure 2 ); one type pectinate chaetae present from postbranchial segments, heterodont, marginal teeth longer than others, shafts narrow, thick, with seven teeth ( Figures 2F View Figure 2 , 5B View Figure 5 ); compound spiniger chaetae with smooth and tapering blade approximately 156 µm long ( Figures 2C View Figure 2 , 5E View Figure 5 ); shafts inflated. Compound falciger chaetae present only in posterior chaetigers, observed one per parapodium. Proximal tooth triangular, distal tooth thin, smaller than proximal one; blade 39 µm long; shafts inflated, marginally serrated ( Figures 2E View Figure 2 , 5D View Figure 5 ). Aciculae black with pale tips, two to three per parapodia, tapering, distally blunt. Subacicular hooks dark brown with light tips, unidentate with a terminal hood ( Figures 2D View Figure 2 , 4A–C View Figure 4 , 5C View Figure 5 ), first present from chaetiger 38.


Eastern Mediterranean.


The new species is dedicated to Prof. Dr Melih Ertan Çinar, from Ege University, who made excellent contributions to the understanding of polychaete diversity inhabiting the Turkish coasts.
