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 postenor 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, antenor 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 short (2 /Lm long) outer labial and long (18 /Lm 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 postenor 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 /Lm long) cephalic sensilla, spicules bent at the antenor end and a short stout gubernaculum that is sharp-pointed and hooked on the postenor end; Ptycholaimellus penninae sp.n. is characterised by a blunt anterior end, inconspicuous labial sensilla and
5 /µm 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 /µm 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 (> 1 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 cylindncal tail end, raised lateral
alae, promment labial rugae, open loop-shaped amphids and in female the vagina walls 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
