“…Serov and Wilson (1995) provided the only comprehensive generic review and reappraisal of this family. More recently the genera Machatrium Bruce &Buxton, 2013 andOnychatrium Bruce &Cumming, 2015 were described, including new species from the Great Barrier Reef, Australia. Marine stenetriids are diverse, abundant and omni-present on coral reefs (Kensley 1984a;1988;Müller 1990;1991a, b;Kensley and Schotte 2002;Martin et al 2003), but still remains relatively poorly documented in tropical Australia (see Bruce and Cumming 2015).…”

The genera Tenupedunculus Schultz, 1982 and Stenobermuda Schultz, 1979 are recorded for the first time from beyond the Southern Ocean, at the Great Barrier Reef, Australia. Tenupedunculus serrulatus sp. n. and Stenobermuda warooga sp. n. are described from Heron Island and Lizard Island respectively, both in the Great Barrier Reef. The genus Tenupedunculus is revised and a new diagnosis presented, with Tenupedunculus virginale Schultz, 1982, T. pulchrum (Schultz, 1982), and T. serrulatus sp. n. being retained within the genus, and the remaining species here regarded as Stenetriidae incertae sedis (eight species).

“…They constitute approximately 33% of all isopod species. Of those 22 species, 16 have been described since 2009 (Bruce 2009, Shimomura and Bruce 2012, Bruce and Buxton 2013, Bruce and Cumming 2015) highlighting the potentially high diversity of the suborder (Roberts et al 2002). Tropical regions from northern and western Australia have an even lower level of recorded species.…”

Lepidocharontidae Galassi & Bruce, fam. n. is erected, containing Lepidocharon Galassi & Bruce, gen. n. and two genera transferred from the family Microparasellidae Karaman, 1934: Microcharon Karaman, 1934 and Janinella Albuquerque, Boulanouar & Coineau, 2014. The genus Angeliera Chappuis & Delamare Deboutteville, 1952 is placed as genus incertae sedis in this family. The Lepidocharontidae is characterised by having rectangular or trapezoidal somites in dorsal view, a single free pleonite, a tendency to reduction of the coxal plates, and the unique uropodal morphology of a large and long uropodal protopod on which the slender uropodal exopod articulates separately and anteriorly to the endopod. Lepidocharon Galassi & Bruce, gen. n. has a 6-segmented antennula, a well-developed antennal scale (rudimentary exopod), long and slender pereiopods 1–7 directed outwards, coxal plates rudimentary, incorporated to the lateral side of the sternites, not discernible in dorsal view, the single pleonite narrower than pereionite 7, scale-like elements bordering the proximal part of male pleopod 1 on posterior side, and stylet-guiding grooves of male pleopod 1 which run parallel to the outer lateral margins of the same pleopod. Lepidocharon priapus Galassi & Bruce, sp. n., type species for the genus, and Lepidocharon lizardensis Galassi & Bruce, sp. n. are described from Lizard Island, northern Great Barrier Reef. The most similar genus is Microcharon, both genera sharing the same general organization of the male pleopods 1 and 2, topology and architecture of the stylet-guiding groove of male pleopod 1, morphology of female operculum, presence of 2 robust claws of different lengths on pereiopodal dactylus 1–7, not sexually dimorphic. Lepidocharon gen. n. differs from Microcharon in the shape of the pereionites, very reduced coxal plates, the presence of imbricate scale-like elements bordering the proximal postero-lateral margins of the male pleopod 1, and the topology of the pereiopods, which are ventro-laterally inserted and directed outwards in Lepidocharon gen. n. and dorso-laterally inserted and directed ventrally in Microcharon. Lepidocharon shares with the genus Janinella the morphology of the tergites and the reduced lacinia mobilis of the left mandible, but differs significantly from Janinella in having a well-developed antennal scale, very reduced coxal plates also in females bearing oostegites, the general morphology and spatial arrangement of the stylet-guiding groove of male pleopod 1 and the possession of a 6-segmented antennula. The family Microparasellidae is redefined as monotypic, the only genus being Microparasellus Karaman, 1933.
