abstract
Seventeen new and known species of the family Chromadoridae are described. The genus Dichromadora is represented by five species. Dichromadora longicaudata sp.n. is characterised by a slender body and thin long tail; Dichromadora gathuai sp.n. is characterised by a blunt anterior end, a raised lateral alae and a gubernaculum that is serrated on the posterior end; D. loiseae sp.n. is characterised by a blunt anterior end with a raised collar, double bulb, spicules with a poorly developed capitulum and seven pre-cloacal supplements; D. cucullata, Lorenzen, 1973 is characterised by lateral differentiation of two (four?) longitudinal rows of dots, seven pre-cloacal supplements and spicules with a rounded capitulum that is open at the tip; D. quadripapillata sp.n. is characterised by a cylindrical body with an elongate tail end, two (four?) longitudinal rows of dots, anterior pharyngeal region with two pairs of setae, spicules with poorly developed capitulum and four (1+3) pre-cloacal supplements. Hypodontolaimus genus has two species. Hypodontolaimus marleenae sp. n. has shore (2 mu m long) outer labial and long (18 mu m long) cephalic sensilla; punctated cuticle with two longitudinal rows of dots, spicules with poorly developed capitulum and eight fine pre-cloacal supplements; Hypodontolaimus aff: angelae Inglis, 1961 is characterised by three somatic setae at the anterior pharyngeal region, a large hollow dorsal tooth, a well-developed posterior pharyngeal bulb and a beak-shaped capitulum. The genus Ptycholaimellus has three species. Ptycholaimellus macrodentatus Timm, 1961 is characterised by a blunt anterior end, papilliform outer labial and setiform (6-8 mu m long) cephalic sensilla, spicules bent at the anterior end and a short stout gubernaculum that is sharp-pointed and hooked on the posterior end; Ptycholamellus penninae sp.n. is characterised by a blunt anterior end, inconspicuous labial sensilla and 5 mu m long cephalic sensilla, a curved spicules with poorly developed capitulum and a gubernaculum that is serrated on the posterior tip; Ptycholaimellus ponticus Filipjev, 1922 is characterised by blunt anterior end, poorly developed vestibulum, inconspicuous labial sensilla and 3 mu m long cephalic sensilla, curved spicules with poorly developed capitulum and a simple gubernaculum. Ptycholaimellus ponticus sensu Gerlach, 1951 is given a new name, P. jenseni sp, n. The genus Trochamus Boucher and Bovee, 1971 is represented by four species. Trochamus bulbosa sp. n. is characterised by a small plump body normally thicker at the mid-body especially in gravid females, annulated and punctated cuticle with a lateral differentiation that is a raised ala, prominent labial rugae, long, slender spicules and conical cylindrical tail. Trochamus complexus Boucher, 1976 is characterised by cylindrical body swollen at the middle, annulated and punctated cuticle with a raised lateral alae, faint circular amphids, small stoma, thin slender spicules and elongate cylindrical tail. Trochamus prosoporus Blome, 1985 is characterised by rather long body (> I mm long), with a blunt anterior end and cylindrical tail end, raised lateral alae, stoma with a large dorsal tooth, curved massive spicules and a gubernaculum with sharp posterior tip. Trochamus polki sp. n. is characterised by cylindrical body with a blunt anterior end and cylindrical tail end, raised lateral alae, prominent labial rugae, open loop-shaped amphids and in female the vagina wall is very refractive. Prochromadorella Mickoletzy, 1924 has two species. Prochromadorella daroae sp, n. is characterised by a slender body attenuating on both ends, heterogeneous cuticle without lateral differentiation, curved spicules with a poorly developed capitulum and no pre-cloacal supplements. Prochromadorella ditlevseni (de Man, 1922), Lorenzen, 1971 is characterised by a slender body, heterogeneous cuticle without lateral differentiation, thin curved spicules and five pre-cloacal supplements. The genus Trichromadora Kreis, 1929 is re-instated and T. longicaudata Kreis, 1929 is redescribed. It is characterised by a slender body and a long tail, cuticle with lateral differentiation of three longitudinal rows of dots throughout the body length, massive spicules with a poorly developed capitulum and five pre-cloacal supplements.
