Minyaspis gen. nov. Type species. Minyaspis amylaneae sp. nov. Type locality. Fiji Is, Great Astrolabe Reef, NE of Dravuni I., 18 ° 44.08’ S, 178 ° 32.63’ E, depth: 14 m. Diagnosis. Scutum thin, fragile, not calcified along carinal and tergal margins, resulting in incomplete coverage of capitulum. Tergum sometimes incompletely calcified. Scutum with pronounced adductor muscle pit. Basal end of carina commonly forked, not rounded or truncate. Etymology. Miny - from the Greek, minys , small, and -aspis , a shield. Remarks. The species placed within this genus are generally defined by partially calcified capitular plates. Although one might consider this reduction in calcification to be a trait commonly found in cirripeds in obligate commensal relationships in which they are closely associated with host taxa tissues (e.g. sponge-inhabiting barnacles, see Kolbasov 1993; Van Syoc and Newman 2010), we contend that in the case of oxynaspidids the reduction of calcification is a synapomorphy of the genus Minyaspis sp. nov. Independent data sets, such as those derived from DNA sequences, could test this hypothesis. To date, however, we have not been able to obtain suitable tissues for DNA extraction from the great bulk of oxynaspidid species. Previously described species of Oxynaspis , newly referred to the genus Minyaspis , ordered alphabetically by species, with the known hosts of type specimens and type localities, are listed below.
