Family Detonidae Budde-Lund, 1904

Remarks

The family Detonidae Budde-Lund, 1904 comprises 39 littoral species in the genera Armadilloniscus Uljanin, 1875 (32 spp.), Deto Guérin-Méneville, 1836 (5 spp.) and Detonella Lohmander, 1927 (2 spp.), including two dubious species, Armadilloniscus minutus Uljanin, 1875 and Deto spinicornis Brandt, 1851 (Schultz 1984; Paoletti & Stinner 1989; Taiti & Ferrara 1989; Schmidt 2002; Schmalfuss 2003; Schmidt & Leistikow 2004; WoRMS 2020b). The family can be characterized by animals having a clinger habitus (sensu Schmalfuss 1984), cephalon with well-developed lateral lobes, dorsal surface more or less tuberculated or with longitudinal ridges, exopods of pleopods 1–5 without respiratory structures and lateral margins covered with thin setae conferring a fringe-like appearance (see Taiti & Ferrara 1989; Schmidt 2002).

Recently, Reinoso-Flórez et al. (2016) recorded the family from Páramo de Estambul (Tolima), Colombia. However, after the re-examination of the material deposited at Colección Zoológica de la Universidad del Tolima (CZUT-IT 1423–1426, see Reinoso-Flórez et al. 2016), the specimens belong to the families Styloniscidae and Philosciidae, and therefore, our work constitutes the first record of the family in the country.
