Description
TABLE 3. Key morphological characters of the currently known species of Paraehlersia.
| Species (Geographical location) | Length of spiniger-like chaetae (µm) | Dorsal simple chaetae | Aciculae | Length of pharynx (chaetigers) | proventricle (chaetigers) / no. of rows of | Shape of posterior falcigers | References |
|---|---|---|---|---|---|---|---|
| P. articulata (Kudenov & Harris, 1995) (California) | 950–1000 | Unidentate on first chaetigers then becoming progressively bidentate | Diamond shaped on the tip at the anterior part of the body, progressively blunt along the body | ~6–7 | ~5 / 22–24 | Bidentate, proximal tooth slightly longer and widter than distal one. Both sharp | Kudenov & Harris (1995) |
| P. dionisi (Núñez y San Martín, 1991) (Canary Islands and Western Mediterranean Sea) | 51–54 | Moderately thick, not bifid strongly serrated margins | Thin, distal thickening with small tip | ~12 | ~7 / 30 | Bidentate, proximal tooth thicker than distal one, c shaped. Short subdistal spines | Nüñez & San Martín (1991); San Martín (2003) |
| P. ehlersiaeformis (Augener, 1913) (Australia) | 50–47 | Bifid with short subdistal spines | Distally acuminate, lancet-shaped | 7 | 5 / 21 | Bidentate, proximal tooth much thicker than distal one, bent at right angle respect to it or slightly curved towards shaft. Short subdistal spines | Augener (1913); San Martín & Hutchings (2006) |
| P. ferrugina (Langerhans, 1881) (North Atlantic Ocean and Mediterranean Sea) | 100–75 | Bidentate, with teeth of different sizes, with short subdistal spines | Truncate, subdistally enlarged, with oblique tip | ~6–7 | 6–7 / ~25 | Bidentate, proximal tooth strongly thicker, downward dressed. Thin sharp distal tooth, upward dressed, following the vertical of the chaeta | Langerhans (1881); Laubier (1968); San Martín (2003) |
| P. kawesqar Soto & San Martín, 2018 (Chilean Patagonia) | 72–48 | Very thin, flat and sharp on mid-posterior segments | Distally acuminate | 7 | 14–15 / ~27 | Bidentate, proximal tooth much thicker and significantly larger than distal one. Short subdistal spines may exist | Soto & San Martín (2018) |
| P. longichaetosa Fukuda et al., 2012 (Brazil) | 120–60 | Bidentate with short subdistal spines | Bent almost at right angle, subdistally irregularly inflated, with pointed tip | 7–9 | 5–8 / 22–28 | Bidentate, proximal tooth slightly thicker than distal one. Short subdistal spines | Fukuda et al. (2012) |
| P. martapolae Fukuda et al., 2012 (Brazil) | 82–35 | Distally irregularly rounded | Bent almost at right angle, apparently flattened on tip | 9–12 | 5–6.5 / 21–24 | Bidentate, short, proximal tooth slightly thicker than distal one. C shaped. Short subdistal spines | Fukuda et al. (2012) |
| P. pamelae n. sp. (Alborán Sea) | 84–99 | Slightly bent tip, bifid with subdistal tooth slightly smaller than distal one | Bent at ~45º, rounded in middle segments, sharp at final segments | 10.5 | ~5 / 18 | Bidentate, c shaped, proximal and distal teeth similar in size, proximal one slightly smaller sometimes. Short subdistal spines | This paper |
| P. weissmannioides (Augener, 1913) (Australia) | 100–95 | Truncate, slightly bifid distally, with short subdistal spines | Straight, distally rounded, oblique with short tip | ~7 | 4–5 / 22 | Bidentate, proximal tooth thick. Long subdistal spines in proximity of tooth | Augener (1913); San Martín & Hutchings (2006) |
