03AD7507A420B00A39BCFA5BFB274DC2.taxon	diagnosis	Diagnosis. (after Decraemer & Smol 2006): Chromadoridae. Body cuticle with complex heterogeneous ornamentation along the body (rarely homogeneous as in Endeolophos Boucher, 1976), often with lateral differentiation. The six outer labial and four cephalic sensilla setiform and may be arranged in a single circlet. Amphideal fovea transverse slit-like or oval, located posterior to the cephalic setae. Buccal cavity with large dorsal tooth, with or without denticles or smaller ventrosublateral teeth. Pharynx with or without defined terminal bulb. Gubernaculum usually with hammer- or L-shaped lateral pieces (wrongly indicated as telamon). Pre-cloacal supplements absent but a pre-cloacal differentiation of body cuticle may be present. Marine. Diagnosis of the genera: Until date Euchromadorinae is comprised of 11 valid genera.	en	Datta, Tridip Kumar, Al-Helal, Md.

03AD7507A427B00039BCFC71FAF2499B.taxon	description	Description. Adults <1 mm long with heavily annulated body. Anterior end flat to round and posterior end tapered. Cheilostome surrounded by twelve folded rugae. Pharyngostome with two subventral teeth and comparatively one large claw-like dorsal tooth. Anterior part of pharyngostome with six OLS (1 – 2 µm long) and four CS (2 – 3 µm long) setiform, arranged in a single crown. At the level of CS, cephalic diameter measures 16 – 18 µm. Amphideal fovea indiscernible, probably located at the cheilo-pharyngo junction as a slit, ca. 43 – 47 % of cephalic diameter. Somatic setae present throughout body but sparse. Pharynx muscular and cylindrical, measures 106 – 153 µm long, ca. 14 – 19 % of total body length. Pharynx ends with one dilated bulb and two thin muscular interruptions anterior of it. Nerve ring located ca. 51 – 56 % of pharynx in respect to anterior end. Cardia indiscernible. Excretory pore located ventral to pharyngeal bulb and ventral gland (28 – 32 µm long) as elongated bulb ventral to anterior part of intestine. Tail conical, 87 – 111 µm long, measures 4 – 5 abd long. Tail end non-annulated (10 – 12 µm) and spinneret bears two setae (4 – 5 µm). Cuticle heterogeneous. Annulation starts just posterior to head capsule. Annulations appear as punctations varied from dotted at anterior end to oval shaped for most of the body. Annulation height less at both ends than rest of the body. Annulation pattern not fully understood because of complex arrangement of cuticular layers. Cuticle appears as corrugated roof-tile in overlapping pattern which in turn gives dotted and oval-shaped optical appearance under light microscopy. Lateral differentiation as elevated ridge (alae) starts at the level of nerve ring anterior to pharyngeal bulb ca. 73 – 79 µm posterior to head end and ends posterior to anus ca. 63 – 73 µm anterior to tail end. The width of ridges vary throughout the body being widest at the mid body level where cuticle appears more complex. Due to upper layer of cuticle the internal structures not properly visible, probably corrugated structures attached with a median rib and one side just beneath the preceding annule while other side above the next annule. The appearance changes with the direction of the cuticular annulations; first change in the annular direction appears ca. 31 % of the anterior body part. Male and female both appears similar except reproductive structures and its associated forms. Male (846 – 887 µm): Reproductive system monorchic with outstretched testis located right to intestine. Spicules long (48 – 51 µm in arc, 38 µm in chord), arcuate. 1.9 – 2.0 of corresponding anal body. Manubrium (capitulum) without any prominence. Gubernaculum small, plate-like (10 µm) running parallel to dorsal of spicules. Germinative zone of testis with broadened anterior end. Vas deferens forms tubular part at distal end and joins with rectum to form cloacal opening. Pre-cloacal modification as cuticular thickening of 11 – 13 annules, located 72 – 80 µm (ca. 24 annules) anterior to cloacal opening. No further post-cloacal modification. Female (720 – 811 µm): Reproductive system amphidelphic with reflexed ovaries; anterior ovary right to intestine and posterior left to it. Both ovaries almost similar in size; anterior being little larger (48 – 74 µm) than posterior (45 – 72 µm). Body diameter at vulva being widest (36 – 39 µm) and located around the mid portion of the body (47 – 52 %). Vulva visible with dilated cuticle. Vagina slit-like with refractive thick muscle and posterior wall folded back resulting in formation of short lumen.	en	Datta, Tridip Kumar, Al-Helal, Md.
