Plateros (Newman, 1838)

Description of medium instar larva. Body widest in basal part of abdomen. Sclerites brown, distinctly reticulate, membranes white. Lateral part of epicranium with lateral membranous area, one stemma in shallow incision in frontolateral part of dorsal epicranial plate. Mandibles slender apically, with long seta at base. Palpifer partly membranous dorsally, mala slender, with one short, subapical seta; maxillary palpi minute, shorter than palpifer. Ventral plate pentagonal. Terga undivided, longer than wide in segments T1–T3 and A8, approximately square in A1–A7, always with distinct rectangular angles. Laterotergites closely attached to terga, inner margin straight, lateral margins convex. Sterna T2 and T3 light, small, weakly sclerotized, with two setae. Spiracular plates T2 small, protruded to form small tubercle, spiracle on apex of tubercle. Frontal pleurite T3 well sclerotized, with lighter, partly membranous area corresponding to position of spiracle in T2. Remaining pleurites, and precoxale T2 and T3 very slightly pigmented. Abdomen with three dorsal sclerites, in pleural part single pleurite bearing spiracle on small, posterodorsal tubercle (figure 72). Tergum A9 entire, transverse, nearly oblong, without urogomphi.
