Taxonomy and Systematics of the Genus Makatinus Heyns, 1965 (Nematoda: Dorylaimida: Aporcelaimidae)

The taxonomy and the systematics of the genus are discussed by means of the characterization of its morphological pattern and the first molecular (D2–D3 expansion segments of 28S rDNA) analysis of a representative of this taxon, from Costa Rica. The presence of two or more pairs of male ad-cloacal g...

Description
Summary:The taxonomy and the systematics of the genus are discussed by means of the characterization of its morphological pattern and the first molecular (D2–D3 expansion segments of 28S rDNA) analysis of a representative of this taxon, from Costa Rica. The presence of two or more pairs of male ad-cloacal genital papillae is the most characteristic autapomorphy of the genus, but the status of its species on this concern differ among them. Both morphological and molecular data support a relationship with , which, however, might not be as close as usually assumed. An emended diagnosis of the genus, a key to species identification, and a compendium of their morphometrics are provided. is regarded as , is retained under , and becomes a junior synonym of
