Genus Lepidobrya Womersley, 1937 Type species. Entomobrya mawsoni Tillyard, 1920 Type locality. Garden Cove, Macquarie Island, Australia. Diagnosis. Antennae four-segmented, shorter than body. Scales narrow, pointed with short striations, and present on Ant. I, legs, head, terga and ventral side of manubrium and dens; scales on furcula elongate and narrower than those on body. Eyes 8+8, G and H smaller. Prelabral chaetae ciliate and labral chaetae smooth. Subapical chaeta of maxillary outer lobe slightly thicker than apical one. Labial chaetae of posterior row ciliate. Mesonotum not humped. Unguis with two inner paired basal teeth and without unpaired teeth. Unguiculus truncate with one minute outer tooth. Tenent hairs clavate. Tenaculum with 4+4 teeth and corpus with one large chaeta. Male genital organ papillate. Dental spines absent. Mucro bidentate with a basal spine. Tergal chaetotaxy polymacrochaetotic; ms as 1, 0|1, 0, 1, 0, 0; sens as 2, 2|1, 2, 2,?, 3. Bothriotricha 2, 3, 2 on Abd. II‒IV; small scales present around bothriotricha. Remarks. The genus Lepidobrya is similar to Lepidosira Schött, 1925 in having scales on dens, a bidentate mucro, dental spines absent, and in similar bothriotrichal and S-chaetotaxic patterns. It differs from Lepidosira in having narrow scales with pointed tips and abundant tergal macrochaetae. Lepidobrya is also closer to Epimetrura Schött, 1925 and Lepidodens Zhang & Pan (in Zhang et al., in press) in having pointed scales; it differs from the former in the absence of a finger-shaped appendix on Abd. VI in reproductive females and unpaired inner teeth on unguis, and from the latter in the presence of short ribs on the scales, the absence of unpaired inner teeth on unguis, and arrangement of S-chaetae on Abd.
