Extracts of Paranemastoma quadripunctatum (Opiliones, Dyspnoi, Nemastomatidae) contained seven components, all of which likely originated from the secretion of well-developed prosomal scent glands. The two main components (together accounting for more than 90% of the secretion) were identified as 1,4-naphthoquinone and 6-methyl-1,4-naphthoquinone. The minor components were 1,4-naphthalenediol, two methoxy-naphthoquinones (2-methoxy-1,4-naphthoquinone, and 2-methoxy-6-methyl-1,4-naphthoquinone) and two anthraquinones (2-methyl-9,10-anthraquinone and a dimethyl-9,10-anthraquinone). While some chemical data on scent gland secretions of the other suborders of Opiliones (Cyphophthalmi, palpatorean Eupnoi, and Laniatores) already exist, this is the first report on the scent gland chemistry in the Dyspnoi. Naphthoquinones are known scent gland exudates of Cyphophthalmi and certain Eupnoi, methoxy-naphthoquinones and anthraquinones are new for opilionid scent gland secretions.
扁须蛩马陆(倍足纲,Dyspnoi,Nemastomatidae)的提取物含有七种成分,它们可能都来自于高度发达的体节臭腺的分泌物。两种主要成分(占分泌物的 90%以上)被鉴定为 1,4-萘醌和 6-甲基-1,4-萘醌。次要成分是 1,4-萘二酚、两种甲氧基萘醌(2-甲氧基-1,4-萘醌和 2-甲氧基-6-甲基-1,4-萘醌)和两种蒽醌(2-甲基-9,10-蒽醌和二甲基-9,10-蒽醌)。虽然其他倍足纲亚目(Cyphophthalmi、有须类 Eupnoi 和 Laniatores)的臭腺分泌物已有一些化学数据,但这是 Dyspnoi 臭腺化学的首次报道。萘醌是 Cyphophthalmi 和某些 Eupnoi 的已知臭腺分泌物,甲氧基萘醌和蒽醌是新的倍足纲臭腺分泌物。
