Infective females were also isolated from abdomen of Eupristina masoni. Schistonchus spp. collected from F. racemosa have been named as-S. cuculloracemosus n. sp.: Males- L = 441-609 μm, a = 24.5-29.3, b = 6.0-9.5, c = 16.0-20.5, excretory pore near lip region, sperm amoeboid, cucullus present, tail with well developed mucro; Females- L = 707-906 μm, a = 17.6-27.8, b = 10.9-15.15, c = 14.5-21.2, V = 70.1-77.6; Infective Females- L = 462-549 μm, a = 26.939.9, b = 6.3-7.8, c = 8.2-11.1, V = 66.8-72.3. Infective females were also isolated from abdomen Ceratosolen fusciceps. S. flagelloracemosus n. sp.: Males- L = 342-446 μm, a = 22.8-32.9, b = 8.1-11.2, c = 21.1-27.5, excretory pore near stylet base, sperm amoeboid, tail with small digitate process at tip; Females- L = 442-504 μm, a = 24.3-30.4, b = 8.0-10.1, c = 12.8-16.8, V = 74.7-78.2. S. mucroracemosus n. sp.: Males- L = 402-571 μm, a = 22.0-36.8, b = 7.1-10.6, c = 21.5-31.8, excretory pore near median pharyngeal bulb, sperm amoeboid, tail without mucro; Females- L = 565-760 μm, a = 16.1-26.9, b = 9.9-15.3, c = 15.8-23.5, V = 75.7-80.8; Infective Females- L = 372-481 μm, a = 23.8-29.9, b = 5.2-6.8, c = 10.3-13.4, V = 70.2-74.9. Infective females were also isolated from abdomen of Apocryptophagus sp. S. caprifici collected from figs of F. carica is a new record from India.
