The genus Uromunna (Crustacea: Isopoda: Munnidae) in New South Wales,Australia, with a key for all known species

The invertebrate collection of the Australian Museum revealed the existence of three new species of the genus Uromunna (family Munnidae) from New South Wales, Australia. Uromunna tenagoika sp. nov. from Batemans Bay has the head anterior margin concave, without simple setae; eyes with few ommatidia, eye lobes with both margins parallel, in male posterior margin directed forward; pereonite 7 as wide as pereonite 6, subequal to pleotelson width; pleotelson distal margin pointed, suburopodal shelf present; mandible palp absent; pereopod I propodus robust setae absent; pereopods relatively short; pleopod IV exopod distal tip with one pappose seta. Uromunna rhamnda sp. nov. from Batemans Bay has a head anterior margin concave, without simple setae; eye lobes with both margins parallel, in male posterior margin parallel to frontal margin; pleotelson distal margin pointed, suburopodal shelf absent; mandible palp present; pereopod I propodus robust setae absent; pleopod IV exopod distal tip with one pappose seta. Uromunna eora sp. nov. was found at Southern Creek, located north of Sydney and is the first species of the genus described from a fully freshwater environment with no marine water input. It has a relatively elongate body (length 3.4× width), anterior margin concave, eye lobes with both margins converging distally, in male posterior margin directed forward; pereonite 7 as wide as pereonite 6, wider than pleotelson width; pleotelson distal margin truncate, suburopodal shelf present; mandible palp present; pereopod I propodus robust setae present; pleopod IV exopod distal tip with two pappose setae. This work raises the number of Uromunna species found in Australia to a total of six.
