Type and type locality. The original description of Joryma tartoor ( Pillai, 1954) was accompanied by brief descriptions of the adult female from the host Opisthopterus tardoore (Cuvier, 1829, Trivandrum, Kerala Coast, India. Pillai (1964) vaguely stated that the type material was deposited in the Indian Museum, Kolkata without any mention of the registration number. Our attempts to retrieve and enquire any ‘potential’ material that could be identified as the type material for J. tartoor ended in vain. As there are no museum records of Pillai’s (1954) material, it seems inevitable that the types were either not deposited or have been subsequently lost.

Remarks. The identification of J. tartoor is also based on the original description by Pillai (1954) and subsequent description by Pillai in 1964 and this species needs an accurate redescription. The species J. tartoor can be easily distinguished from other species of Joryma by the following characteristics: Cephalon covered dorsally by pereonite 1 expansion, pleotelson acutely triangular, pereonite 1 anterolateral expansion bilateral and slightly bilobed, pleonites 1 and 2 overlapped laterally, pleotelson acutely triangular, uropods rami unequal, mandibular palp incompletely 3 segmented. Antenna with 9 or 10 articles, maxilliped with 4 recurved spines.

Joryma tartoor , first described by Pillai (1964) as Agarna tartoor from the type host Sardinella brachysoma . Subsequently, Pillai (1964) provided a description of the female, male, and manca larva. Later, this species was transferred to Joryma by Bowman & Tareen (1983) while expressing reservation about its generic position. After its original description and subsequent redescription by Pillai (1964), there have been no other confirmed reports of this species from anywhere. The records of Joryma tartoor by Ravichandran et al. (2007; 2010) was a misidentification. Ravichandran et al ’s figure (fig. 3 in 2007; 2010) of Joryma tartoor in dorsal and ventral view is a misidentification and it refers to ventral view (female and male) and dorsal view (female and male) of Norileca indica (H. Milne Edwards, 1840) .

Distribution. Trivandrum, Kerala Coast, Arabian Sea ( Pillai 1954, 1964).

Hosts. Opisthopterus tardoore (Cuvier, 1829) ( Pillai 1954, 1964).
