Family Blaniulidae C. L. Koch, 1847

Genus Archiboreoiulus Brolemann, 1921

Brolemann defined the genus Archiboreoiulus in 1921 in the identification key of the genera and species of the family Blaniulidae ( Brolemann, 1921) and in a subsequent extended study on the Blaniulidae ( Brolemann 1923) by the following characters:

41-57 body rings including collum and telson. Short cephalic capsule lacking eyes. Mandibular cardo almost a third of the cheeks; only the internal protuberance well developed. Very strong stipes protuberance.

Coxosternite of the first leg pair not divided in the median line. Shaped like hooks, they have no trace of articulation and are united with the coxosternites and among themselves; the point of contact among the two legs is easily recognizable, and their tips are slightly divergent. Each leg bears at the tip a fleshy cone.

Coxal processes formed by a strongly chitinised central part, basally narrowed and with the external edges developed in large, bulging hyaline blades, with a posteriorly oriented cavity. Short telopodites, slightly longer than a quarter of the coxal processes. The articular fossette opens posteriorly.

Of the two apical leaflets of the gonopods, the enveloping one is slightly shorter and only its external edge is cut out in at least a dozen fringes with a simple tip.

Gonopodal sternite presents an external basal horn, a character shared with other members of the Boreoiulini tribe ( Brolemann 1921).

In females, the apodematique gutter without a diverticulum.
