Family Linhomoeidae Filipjev, 1922

Diagnosis (from Fonseca & Bezerra 2014)

Cuticle often striated and seldom smooth. Inner labial sensilla as papilla or not visible. Amphids circular in most cases; seldom curved into a round bow-like shape. Inner side of labial region often formed by an annular, soft skinned pad that narrows the buccal aperture. Cardia noticeably lengthened. Two outstretched gonads facing opposite directions, seldom single gonad. Anterior gonad to the left or right of intestine, and posterior gonad to opposite side.

Remarks

The Linhomoeidae comprises three subfamilies: the Linhomoeinae Filipjev, 1922, Desmolaiminae Schneider, 1926 and Eletherolaiminae Filipjev, 1922. These subfamilies are differentiated mainly based on the arrangement of cephalic sensilla and structure of the buccal cavity.
