8117E0644E57FFFCFF3A736385B1238A.taxon	diagnosis	Diagnosis. Peristomial lip constricted into a projecting tube protruding outwards from apical end of cell (Figs 2 D, E; 3 C). Elongate macronucleus oriented longitudinally to main axis of cell (Figs 2 D, E; 3 C). Contracted zooid ovoid in shape, with conspicuous folds posteriorly (Figs 2 D; 3 C) (Corliss 1979; Lynn & Small 2002).	en	Bharathidasan, Veeraiyan, Sarathy, Palanivel Partha, Murugesan, Perumal, Nogueira, João Miguel De Matos (2021): New records for associations between peritrich protozoan ciliates (Ciliophora, Sessilida) and polychaete worms (Annelida) from off the southeastern coast of India.

8117E0644E51FFFAFF3A77D68342211F.taxon	diagnosis	Diagnosis. Operculum as long as wide, in two symmetrical lobes; distal disc flat and perpendicular to longitudinal axis; numerous opercular papillae around operculum. Outer paleae numerous, in semicircles, paleae geniculate, with flat blades and smooth lateral edges. Inner opercular paleae of various shapes, apparently in two concentric rows. Middle paleae strongly geniculate with excavated blades and smooth margins, pointing outwards; innermost paleae directed inwards. Nuchal spines, if present, as 3 – 6 pairs of straight spines. Neuropodia of segment 1 with one pair of conical cirri and capillary chaetae. Building organ with one triangular lobe ventrally at each side. Thoracic branchiae present. Three parathoracic segments, notochaetae alternating lanceolate and capillaries, neurochaetae similar in shape but smaller. Abdominal branchiae present on most segments, sometimes absent on posterior body (Fig. 4 A) (Capa & Hutchings 2019).	en	Bharathidasan, Veeraiyan, Sarathy, Palanivel Partha, Murugesan, Perumal, Nogueira, João Miguel De Matos (2021): New records for associations between peritrich protozoan ciliates (Ciliophora, Sessilida) and polychaete worms (Annelida) from off the southeastern coast of India.

8117E0644E51FFFAFF3A727A80402328.taxon	diagnosis	Diagnosis. Long body, usually with more than 150 chaetigers. Trapezoidal prostomium, with short subconical antennae, two pairs of eyes (eyes absent rarely). Four pairs of tentacular cirri. Dorsal cirri with cylindrical cirrophores on anterior body, and flattened cirrophores on posterior body. Notochaetae usually present; preacicular neurochaetae usually as heterogomph falcigers; postacicular neurochaetae, in most species, as sesquigomph spinigers in supraacicular fascicle and heterogomph spinigers in sub-acicular fascicle; pygidium button-like (Fig. 3 A) (Alves & Santos 2016).	en	Bharathidasan, Veeraiyan, Sarathy, Palanivel Partha, Murugesan, Perumal, Nogueira, João Miguel De Matos (2021): New records for associations between peritrich protozoan ciliates (Ciliophora, Sessilida) and polychaete worms (Annelida) from off the southeastern coast of India.

8117E0644E56FFFDFF3A730C8244239D.taxon	diagnosis	Diagnosis. Circular anterior opening in top view, edge lacking outgrows. Short stalk, cylindrical, without folds, mesostyle and endostyle both absent; stalk sometimes with longitudinal striae. One or two small zooids present per lorica. Contractile vacuole small, at peristomial region. Macronucleus straight, pellicular striations inconspicuous (Fig. 4 B, C) (Warren & Paynter 1991; Lynn & Small 2000).	en	Bharathidasan, Veeraiyan, Sarathy, Palanivel Partha, Murugesan, Perumal, Nogueira, João Miguel De Matos (2021): New records for associations between peritrich protozoan ciliates (Ciliophora, Sessilida) and polychaete worms (Annelida) from off the southeastern coast of India.

8117E0644E51FFFAFF3A75DE85182773.taxon	diagnosis	Diagnosis. Three pairs of branching branchie with short main stalks, usually on segments 2 – 4, but sometimes on discontinuous segments. Notopodia beginning on segment 4, extending for variable number of segments, frequently to posterior body; notochaetae medially winged and distally serrated, and alimbate and serrated, frequently with blade at an angle, usually with transition on types of chaetae from anterior to midbody notopodia. Neuropodia beginning on segment 5, with short handled avicular uncini in completely intercalated to partially back-to-back double rows from segment 11 until posterior body (Fig. 2 A, B) (Hutchings et al. 2021).	en	Bharathidasan, Veeraiyan, Sarathy, Palanivel Partha, Murugesan, Perumal, Nogueira, João Miguel De Matos (2021): New records for associations between peritrich protozoan ciliates (Ciliophora, Sessilida) and polychaete worms (Annelida) from off the southeastern coast of India.
