title: [Life cycle of Tetrameres (Microtetrameres) inermis (Linstow, 1879): tetramerid nematode parasite of the weaver Ploceus aurantius in Togo].
abstract: The tetramerid nematode Tetrameres (Microtetrameres) inermis (Linstow, 1879), was found in the weaver Ploceus aurantius in Togo. Its larval biology was studied in experimentally infected orthopterans Tylotropidius patagiatus and Locusta migratoria (Acrididae). The length of infective third-stage larvae of T. (M.) inermis (1.5-1.6 mm) was shorter (2.2-2.6 mm) than those of the larvae of T. (M.) corax and T. (M.) helix. In the family Tetrameridae the primitive nature of the sub-genus Microtetrameres in revealed by the presence of developed pseudolabia which resemble the cephalic structures in the Spiruridae, and by the type of encapsulation of the parasite in the adipose tissue of the insect intermediate host. As with Cyrnea eurycerca (Habronematidae) the infective larvae leave their capsule and are found free in the hemocoele.
