Remarks

• Systematics: Kerria maduraiensis is similar to Kerria fici fici (Green) in having: (i) a hispid supra-anal plate, (ii) a short brachia, (iii) a long dorsal spine with a short pedicel, and (iv) long antennae. However, it differs in having (character states for K. fici fici in brackets): (i) a larger body, 1.22-3.96 mm long (1.08-1.6 mm long); (ii) the supra-anal plate elongated (abbreviated); (iii) 5 or 6 dimples on the brachial plate (4 or 5); (iv) distance between the anterior spiracle and brachial plate 85-400 ìm (17-86 ìm); (v) anterior spiracle large 275-335 μm (155-241ìm); and (vi) antennal apex with 4 long and 2 short setae (2 long and 2 short setae). Kerria maduraiensis also resembles Kerria fici jhansiensis (Misra) in having: (i) sessile brachia and (ii) dorsal spine nearly twice the diameter of the brachial crater, but the new species differs in having (character states for K. jhansiensis in brackets): (i) 5 or 6 dimples on the brachial plate (6-8); (ii) 8 or 9 perivulvar pore clusters on each side at the base of the anal tubercle (10); (iii) each marginal duct cluster with 39-42 ducts (more than 45), and (iv) antennae 3 segmented (2 segmented).
