Description: the average measurements obtained from 6 specimens are: 4.0-8.1 (5.6 mm) in total length by
1.12-1.71 (1.4 mm) maximum width; a short esophagus and a muscular pharynx that was longer than wide (0.15
mm by 0.12 mm); a post-bifurcal genital pore with a long cirrus sac running from the level of the acetabulum
close to the genital pore; acetabulum 0.41 mm in diameter 0.37–0.44 mm; a pre-testicular ovary (0.55 width by
0.30 length), typically with 4 primary lobes and a variable number of secondary lobes; a coiled uterus with 5 to 6
loops between the ovary and the posterior end of the acetabulum; 9 rounded testes (0.35 mm wide); irregularly
shaped vitelline follicles extending from the intestinal bifurcation to the end of the body running continuously
along both sides of the body.

Monascus
sp. especially known from fishes caught in subtropical and tropical seas, with most records from the
Mediterranean. Most records are from fishes of the family Carangidae. The Original name of the genus

(Odhner 1911); synonym
Haplocladus orientalis
(Srivastava, 1941); synonym according to Bray and Gibson (1980),
Haplocladus typicus
(Odhner, 1911),
Monascus elongatus
(Karyakarte and Yadav, 1976),
Monascus monenteron
(Looss, 1907),
Monascus ovilobatus
(Kumari, 1975), Monascus typicus (Odhner, 1911; Looss, 1912); synonym

(Travassos et al., 1967); synonym
Monascus orientalis
(Srivastava, 1941; Yamaguti, 1958); in addition to that
