Remarks

• Systematics: Kerria thrissurensis is similar to K. pusana (Misra) in having: (i) a large, globular body, (ii) the supra-anal plate hispid and shorter than brachia, (iii) the brachia prominently elevated and tubular, (iv) the anterior spiracle far from brachial plate at a distance greater than the width of the brachial plate, and (v) the dorsal spine not longer than pedicel. Kerria thrissurensis differs in having (character states for K. pusana in brackets): (i) supra-anal plate elongated (abbreviated); (ii) perivulvar pore clusters numbering 12–14 on each side of the base of anal tubercle (10); (iii) 4 or 5 dimples on the brachial plate (5 or 6); and (iv) 49-53 ducts in each marginal duct cluster with surrounding sclerotization (35-40 ducts without sclerotization). (Ahmad, et al., 2013)
• Structure: Lac test brown, each test with a thick, hard resinous covering. Tests occur in aggregations; live mature females elongated and crimson. Female with an elongated anal tubercle and elevated brachia. (Ahmad, et al., 2013)
