Origin: A borrowing from Latin. Etymon: Latin Abdominalia.

Etymology: < scientific Latin Abdominalia (see quot. 1854) < post-classical Latin abdominalis abdominal adj. + -ia -ia suffix².Darwin's name was based on the misconception that the cirri of these barnacles were carried by the abdominal segments, whereas in fact they were thoracic.

Zoology (now historical).

With plural agreement. A former order of barnacles which bore into a variety of calcareous material, comprising typically small, shell-less forms having several pairs of cirri towards the end of the thorax. Abdominalia were renamed Acrothoracica in 1905.

1854 C. Darwin Monogr. Cirripedia II. 20 It has been seen that I divide the Cirripedia into three orders,—the Thoracica, Abdominalia, and Apoda.

1876 P. J. Van Beneden Animal Parasites & Messmates 55 The whole family of the Abdominalia, a name proposed by Darwin, if I am not mistaken, have the sexes separate.

1893 T. R. R. Stebbing Hist. Crustacea i. 11 The Abdominalia have the cirri only on the so-called abdomen.

1973 Systematic Zool. 22 135/2 He erected a separate order, Abdominalia, for the genus in which the females had diverged so much.
