Diagnosis. Pseudorostral horns very long ( Fig. 21E, F View Fig ). Hepatic, lateral and branchial spines very long; median row with 4 or 5 spines: 2 or 3 gastric, 1 cardiac, 1 intestinal; 2 strong spines on posterior carapace margin ( Fig. 21E, F View Fig ). Surface of thoracic sternum distinctly granulated ( Fig. 50B View Fig ). Chela of adult male slender, without distinct carina ( Fig. 54B View Fig ). Ambulatory meri in adults relatively slender, long ( Fig. 21E, F View Fig ). G1 more strongly curved especially distally ( Fig. 23D–F View Fig ).
Etymology. The name is derived from the old English word for jewel and ornament, alluding to the beautiful arrangement of red spines and tubercles of the species. It also indirectly alludes to the exclamation for pain, associated with careless handling of the present spiny species. Used as a noun in apposition.
Remarks. The character used in their keys by Serène & Lohavanijaya (1973), T. Sakai (1976) and Griffin & Tranter (1986) concerning a proximal tooth on the outer margin of antenna looks very variable. On some specimens there are only two branchial spines. Even on the juvenile specimens (female 28 mm carapace length, ZRC 2013.1282) the characteristics of P. ouch n. sp. are well marked: the pseudorostral spines are long and very divergent but less curved upward than in the adults; and the spines on the lateral margin of the carapace are very long.
Paramaya ouch is superficially similar to P. spinigera but can be distinguished easily by the following characters: the spines are proportionately much longer in P. ouch than in P. spinigera ( Fig. 21E, F View Fig versus Fig. 21A–D View Fig ); the antorbital spine is relatively shorter and not as curved as in P. ouch ( Fig. 37B View Fig ) than in P. spinigera ( Fig. 37A View Fig ); and the G1 of P. ouch is more distinctly curved distally ( Fig. 23D–F View Fig ) (versus less curved in P. spinigera , Fig. 23A–C View Fig ).
The structure of the chela is interesting because in P. spinigera , the adult male chela is distinctly inflated and the margins are clearly carinated ( Fig. 54A View Fig ). In adult P. ouch , the male chela is not inflated and there is no distinct carina, although in some of the largest males, the proximal part appears to be weakly carinated ( Fig. 54B View Fig ). Whether the carina is associated with size or dominance, or is a useful species character cannot be ascertained.
Paramaya ouch is very common on the reef slopes of Balicasag Island. The large series of males, females and juveniles were useful to observe the variation of spines with size.
