d); or spermathecae reduced and non-functional. Male sexual system holandric, testes and funnels free in x, xi; small seminal vesicles in ix, xii; tubular prostates with short glands slightly longer than ducts, short delicate ducts, sharply marked from glandular portion; penial setal follicles just median to ducts. Penial setae absent, vestigial or numerous but small, straight, unornamented, monomorphic.
