Trichoniscoides bellesi Reboleira & Taiti, 2015: 9, figs 4–6.

Remarks

This species is characterized by a granulated dorsal integument, antennae with tubercles bearing scale-setae, and pereopod 7 without sexual dimorphism (Table 1). The male pleopod I endopod lacks a distal lobe, and the exopod is triangular with a rounded external edge and without any notch at the base of the two equal ciliated rami. The male pleopod II endopod has a distal segment 2.2 × the length of the basal segment, which is very thick with a tapered tip. This is a troglobiotic species (Table 1).

Distribution

This species is only known from a single cave in Portugal, Algar do Javali (Lisbon, Montejunto Massif) (Reboleira et al. 2015; Fig. 1).
