Meylis dicephalus (Yeates, 1967) Goseco, Ferris & Ferris, 1974.

Type species of the genus

Synonym
Leptonchus dicephalus Yeates, 1967

Morphology and Anatomy:

Body length 1.75-2.9 mm; the larger size is a distinguishing feature from M. multipapillatus
Outer layer of cuticle with fine transverse striations; subcuticle with coarser striations.
Body pores in single row along ventral margin of leteral field
Esophageal bulb large, cylindroid, separated from anterior portion by a constriction.
Cardia large, distinct.
Tail rounded to bluntly conoid.

	Female: Didelphic, amphidelphic. Vulva transverse. Ovaries symmetrical. reflexed at abouit 50% of length. Ref:: Peralta and Pena-Santiago (1996); Goseco et al. (1974)
Males: Diorchic, testes outstretched. 12-20 closely-spaced ventro-median supplements. Tail bluntly conoid, longer than that of female.
