This paper reports for the first time the morphology of larval stages of Setaria labiato-papillosa. The infective larvae of this species had two circles of small papillae on the cephalic end, 4 papillae for outer circle and 6 for inner circle. The caudal end of S. labiato-papillosa is in digital form with 3 transversally arranged papillae. There are 2 circles of small papillae on the cephalic end of S. leichungwingi and S. equina, 4 for each circle; the caudal terminal of the former species is willow-shaped with 3 pearl-like papillae, and that of the latter is conical shaped with 1 bulbed papilla, 2 slightly protruded papillae at sub-terminal. The anal ratios of all the above 3 species are below 3. Morphology of larval stages of Dirofilaria repens was also primarily described in China. The 3 bulbed caudal papillae of the infective larvae are closely arranged, and the anal ratio being less than 2. A key to infective larvae of 8 species of filaria was worked out according to relevant literature and the present study.
