Euchromadorinae Gerlach and Riemann 1973

Subfamily Euchromadorinae Gerlach and Riemann, 1973

Diagnosis [afler Tchesunov (2014)]. Chromadoridae. Body cuticle usually with complex heterogeneous ornamentation along the body, with or without lateral differentiation. The six outer labial and four cephalic sensilla setiform may be arranged in a single circle. 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 [sometimes mistakenly called as “telamon,” which indicates a thickened immovable plate of ventral cloacal wall in Strongylida (cf. Maggenti 1981; Tchesunov 2014)]. Precloacal supplements absent, but a precloacal differentiation of body cuticle may be present.

Type genus. Euchromadora de Man, 1886.

Other genera. Ten genera:

1. Actinonema Cobb, 1920 = Pareuchromadora Schuurmans Stekhoven and Adam, 1931 [synonymized by Wieser (1954)];

2. Adeuchromadora Boucher and de Bovée, 1971;

3. Crestanema Pastor de Ward, 1985;

4. Endeolophos Boucher, 1976;

5. Graphonema Cobb, 1898 = Protochromadora Inglis, 1969 [synonymized by Warwick and Coles (1975)];

6. Parapinnanema Inglis, 1969 = Austranema Inglis, 1969 [synonymized by Warwick and Coles (1975)];

7. Portmacquaria Blome, 2005 = Macquaria Blome, 2002 (junior homonym of Macquaria Cuvier in Cuvier and Valenciennes, 1830);

8. Rhips Cobb, 1920;

9. Steineridora Inglis, 1969; and

10. Trochamus Boucher and de Bovée, 1971.

Remarks. Eleven genera, including the type genus, are valid (Inglis 1969; Gerlach and Riemann 1973; Warwick and Coles 1975; Blome 2002, 2005; Tchesunov 2014). Four other genera— Dasylaimus Cobb, 1933, Dicriconema Steiner and Hoeppli, 1926, Nygmatonchus Cobb, 1933, and Odontocricus Steiner, 1918 —were placed in Euchromadorinae before, but recently, these are now treated as genera inquirendae (Coles 1965; Inglis 1969; Hope and Murphy 1972; Warwick and Coles 1975).
