FIGURE 6. SEM photographs of Steinernema guangdongense n. sp. infective juvenile. A­B, anterior region showing one lateral line, closed mouth (m), amphids (a) and cephalic (c) papillae. C, lateral field with 2 ridges (3 incisures). D, lateral field showing the change of lateral field pattern from 2 to 7 ridges. E, lateral field showing 7 ridges and the middle one (number 4) is divided into 2 making 8 ridges in lateral field. F, lateral field showing phasmid (p) and 7 ridges changing to 4 then 2.
