The genus has most recently been reviewed by Delaney (1989) who gave a genus diagnosis, listed all the included species at that time, and gave a key to the genera of Corallanidae. That generic diagnosis is not in need of revision, but we draw attention to the prime characters for identifying the genus, which are elongate maxilliped, with notably quadrate articles and elongate basis (3.5–4.0 as long as wide), frontal lamina generally small, sometimes reduced or absent and, typically in mature individuals, the uropoda have an elongate exopod that extends to or beyond the posterior margin of the endopod. Other characters rest largely with the mouthparts and require dissection to observe; these are maxillula strongly curved, with single unguis-like apex and the maxilla is a simple bi-articled lobe. The genus that is most often confused with Corallana is Tachaea, but the latter genus can best be separated by the maxilliped palp with short and less quadrate articles, and often with some fusion of those articles.</p> <p>Delaney (1989) identified the following characters as generic apomorphies: mandible incisor either short or long (most other genera have a shorter mandibular incisor); maxilliped slender, basis narrow and very elongate (length = 2.0–4.0 times width); and frontal lamina usually reduced, sometimes absent.</p> <p>Identification of species of Corallana has long been and continues to be difficult, as evidenced by the numerous instances of misidentified species at both genus and species level. Further, several of the species described in 1800s are simply unrecognizable (see species list herein) and cannot be applied to collected specimens. Many species are very similar to each other and another difficulty lies with the species characters being shown primarily by mature adults. It therefore also must be considered that a number of the species described from one locality (“Ubay”) in the Philippines by Schioedte &amp; Meinert (1879) may be different stages of maturity of the same species.</p> <p>The frontal lamina in the genus Corallana. Figure 2 provides a comparison of the shape of the frontal lamina for those species of Corallana for which it has been illustrated, including records of Corallana sp. It can be seen that, while the frontal lamina is usually relatively small compared to Argathona and perhaps Alcirona, when present the shape varies considerably between species. As such the frontal lamina is a useful character to both identify species, but also to identify the immature stages of species. At least two species, Corallana nodosa of Beng Chu &amp; Bruce (2010, figs 1–3; not Corallana nodosa Schioedte &amp; Meinert, 1879) and Corallana grandiventra Ho &amp; Tonguthai, 1992 appear to lack a visible frontal lamina. A clear figure of the frontal lamina should be included in all descriptions of species of Corallana.</p> </div>	http://treatment.plazi.org/id/292387D1FFD9F463FF59FE770777F9EC	Public Domain	No known copyright restrictions apply.

Corallana mishrai sp. nov. can be identified by the frontal lamina with short straight (or very weakly convex) lateral margins and the anterior margin forming a strong acute median point; pleotelson length 0.76 greatest width, with five robust setae on the posterior margin; the uropodal exopod is seven times longer than greatest width, extending beyond endopod by one fourth of its length; endopod lateral margin slightly convex with four robust setae and PMS, apex forms a slightly obtuse angle with long simple setae, mesial margin weakly convex with two robust setae and PMS; bidentate mandible; transverse row of six tubercles present on pereonite 1 and pleonites 2, 3 and 4 lacking lateral tubercles.</p> <p>Corallana mishrai sp. nov. appears similar to C. nodosa Schioedte &amp; Meinert, 1879, from the Philippines, but Corallana mishrai sp. nov., differs to that species in having a frontal lamina with short straight (or very weakly convex) lateral margins and the anterior margin forming a strong acute median point (vs lateral margins that diverge anteriorly, with a single anterior margin that is strongly concave in C. nodosa, see Fig. 2F), a median transverse row of six tubercles on pereonite 1(vs absent on pereonite 1 in C. nodosa).</p> <p>Corallana mishrai sp. nov. differs from C. estuaria Jones et al. 1983 from Papua New Guinea, in the pleotelson apex bearing five robust setae (vs 11–12 robust setae in C. estuaria), uropod endopod apex forming a slightly obtuse angle with six robust setae on lateral and mesial margins (vs acute angle with eight robust setae on outer and inner margins in C. estuaria), uropod exopod seven times longer than greatest width, extending beyond endopod by one fourth of its length (vs six times longer than greatest width, extending beyond endopod by one third of its length in C. estuaria), frontal lamina conspicuous, 8.0 times wider than long with large anterior acute medial point (vs inconspicuous, 6.0 times wider than long with small anterior medial point in C. estuaria).</p> <p>Based on frontal lamina shape Corallana mishrai sp. nov. differs from C. basalis Heller, 1868; C. brevipes Schioedte &amp; Meinert, 1879; C. collaris Schioedte &amp; Meinert, 1879; C. hirticauda (Dana, 1853); Corallana sp.
