Remarks

• Systematics: This species is close to Acanthomytilus intermittens (Hall) separated from the latter by larger pygidial lobes, shorter gland spines and larger number of dorsal glands (Borchsenius, 1959b).
• Structure: Adult female body elongate, narrow. Sides of metathorax and first abdominal segments broadly rounded, posterior section of pygidium rounded or slightly truncate. Next to the anterior spiracles are placed 2-3 disc glands. Median lobes of pygidium elongate, rounded on top, distance between median lobes equal to or wider or slightly exceed their width. Second pair of lobes large, bilobed. Gland spines well developed, on pygidium arranged in 7 groups of 2 and 1 gland spines; along sides of segment 4 of abdomen are placed 2 shorter gland spines; along sides of segments 1-3 of the abdomen, 4-5 conical gland spines. Marginal glands on each side of the body arranged in 4 groups of 1-2-1-1 glands. Dorsal glands large, on the pygidium somewhat smaller than the marginal glands; on the other abdominal segments the dorsal glands form 2 rows on each side of the body; a large group of glands developed on the metathorax and a small number of glands- along sides of mesothorax. Formula of perivulvar glands 2-4 (12-15) 6-8; glands of anterior and anterio-lateral groups often joined. Female scale elongate, narrow, golden yellow, two larval exuviae, both yellow; fully developed scale 2.7-3.0 mm long (Borchsenius, 1959b).
• General Remarks: Detailed description and illustration by Borchsenius (1959b).
