Cirolana can be identified by having the following combination of relatively easy to observe characters: frontal lamina with a relatively wide and ventral flat surface, clypeus always flat (i.e., without ventral or anterior projecting blade), pleonite 5 always laterally entirely overlapped by pleonite 4; mandible incisor visibly broad, more than 0.5 mandible width (see Bruce &amp; Hughes 2020), pereopods all ambulatory (i.e., without marked flatting of articles or presence of long natatory setae), pereopods 1–3 without anterolateral margins of ischium and or merus strongly produced and pleopod 2 appendix masculina attached basally.</p><p>The concept of what constituted Cirolana Leach, 1818, then with 114 species, was wholly revised by Bruce (1981), resulting in the genus including just 44 species. Since that time the genus has again grown, now the largest in the family with 144 species (see Sidabalok &amp; Bruce 2018a), and in the course of that time it has been increasingly recognized that there are distinct groups within the genus (Bruce 1986, 2004; Sidabalok &amp; Bruce 2017, 2018a). Sidabalok (2019) demonstrated that there are five definable monophyletic clades within Cirolana, each clade supported by definable synapomorphies.</p><p>One such clade was termed the Cirolana ‘ pleonastica -group’ by Sidabalok &amp; Bruce (2018a); both new species described here belong to that group. The critical apomorphic characters that define the Cirolana ‘ pleonastica -group’ include: rostral point absent, transverse sutures present on all or most pereonites, pleonites 3 and 4 with small nodules, uropod endopod with setae on distal third, and uropodal exopod lateral margin with three widely spaced relatively slender robust setae. There are several other characters consistently shown by species of this group, including all species in the group with the lateral margins of pleonite 3 not posteriorly produced, not overlapping pleonites 4 and 5 and the posterolateral margins (epimera) of pleonite 4 are posteriorly rounded. At present the Cirolana ‘ pleonastica -group’ has been recorded primarily from the tropical Indo-Pacific Ocean with one species from the Antarctic.</p><p>Both new species described here belong to the Cirolana ‘ pleonastica -group’.</p></div>	https://treatment.plazi.org/id/A02387D80055FFDCFF56FEA5FBCCE97B	Public Domain	No known copyright restrictions apply.

Adult males (n=10) 6.5–8.3 mm (mean 7.7 mm); females (n=7) 7.4–8.5 mm (mean 8.0 mm).</p><p>Remarks. Cirolana khamensis sp. nov. is characterized by pereonites 1–3 each with a single transverse impressed line; pereonites 4–6 with each with two transverse impressed lines; pereonite 7 with three transverse lines with the posterior line forming a nodulose ridge; the antennula peduncular articles 1 and 2 are distinct and articulated; pleotelson dorsal surface with two sub-median longitudinal carinae, each of which has four prominent tubercles, posterior margin evenly rounded, with eight robust setae; pereopod 1 merus inferior margin with six molariform RS; lateral margin of uropodal exopod having continuous row of PMS; and penes in the form of two low tubercles separated by 25% of sternal width.</p><p>We place Cirolana khamensis into the Cirolana ‘pleonastica -group’ as the species shows all the characters for that group, with the exception of the uropodal exopod lateral margin, which has setae along the distal two-thirds of its length, though not the entire length. Nonetheless, the morphology and setation of the uropodal exopod is closer to that of the Cirolana ‘pleonastica -group’ than to the other clades, and furthermore C. khamensis lacks the defining characters of the other groups (see Sidabalok 2019). In their diagnosis of the ‘pleonastica -group’, Sidabalok &amp; Bruce (2018a) state the uropod exopod lateral margin character is usually present.</p><p>Similar South-East Asian species in the Cirolana ‘pleonastica -group’ are Cirolana phuketensis Rodcharoen et al., 2017 (Thailand), C. merlion Sidabalok &amp; Bruce, 2018 (Singapore), C. fasfes Sidabalok &amp; Bruce 2018 (Indonesia) (Sidabalok &amp; Bruce 2018a). However, the new species can be distinguished from those species by lateral margin of uropodal exopod having a more continuous row of PMS (vs uropodal exopod lateral margin with widelyspaced and acute robust setae). Moreover, C. khamensis sp. nov. can be separated from the allopatric species C. bruscai Bruce &amp; Olesen, 2002 by the head not being produced and overriding the antennular bases; and the inferior margins of pereopods 6 and 7 are smooth (vs head weakly produced and overriding the antennular bases; inferior margins of pereopods 6 and 7 serrate in C. bruscai).</p><p>Etymology.

(nine vs five tubercles).</p><p>Etymology.
