Description

Genus Linhomoeus Bastian, 1865

Paralinhomoeus De Man, 1907: 240.

Eulinhomoeus De Man, 1907: 239.

Type species

Linhomoeus elongatus Bastian, 1865.

Diagnosis (modified from Fonseca & Bezerra 2014)

Cuticle finely striated. Six inner labial papillae; six outer labial setae and four cephalic setae in one circle with the cephalic setae longer than the outer labial setae; additional setae may be present. Amphids circular, cryptospiral or cryptocircular. Buccal cavity cup-shaped, more or less cuticularized, sometimes with teeth or plates, and sometimes divided by a cuticular ring. Pharynx posteriorly enlarged, without forming a distinct bulb. Cardia usually conspicuous and elongated. Two outstretched ovaries. Gubernaculum with dorsal apophyses. Tail conical or conicocylindrical.

Remarks

Linhomoeus was synonymised with Paralihomoeus De Man, 1907 by Fonseca & Bezerra (2014) because no clear diagnoses could be provided to distinguish these genera. According to the latter authors, a total of 59 species now belong to Linhomoeus.
