Revision of the Neotropical Scleropactidae (Crustacea: Oniscidea) Author Schmidt, Christian text Zoological Journal of the Linnean Society 2007 2007-11-30 151 1 339 https://academic.oup.com/zoolinnean/article-lookup/doi/10.1111/j.1096-3642.2007.00286.x journal article 10.1111/j.1096-3642.2007.00286.x 0024-4082 5430080 GLOBOPACTES GEN. NOV. Type species: Globopactes falconensis sp. nov. Diagnosis Scleropactids with endoantennal conglobation ability. Eyes and pigment well developed. Coxal plate 1 simple (without schisma). Uropod sympodites longer than broad and with outer corner rounded. Maxilliped palp proximal article with only one large seta. Anterior pereiopods of male with scale-fields. Pleopods 1 and 2 with simple dorsal respiratory fields. Apomorphies of Globopactes 1. male pereiopod 7 merus with ventroproximal scaly tubercle (without such tubercle) 2. male pleopod 1 endopodite with distal portion straight (distal part bent laterally) Derivation of the name Latin globus (sphere), referring to the conglobation ability, and - pactes as posterior part of the name Scleropactes , to indicate that the new genus belongs to the Scleropactidae . Phylogeny within the genus Globopactes Within the genus, G. senex , G. falconensis and G. granulatus are clearly identifiable as most closely related species. In the phylogenetic analysis (see above), they form clade 28. Their common derived characters are coxal plates 2 and 3, which have deeply concave lateral margins, adapted to conglobation. This is one of the few characters that does not require the assumption of convergency within the Scleropactidae .
