( Figs. 51–63 View FIGURES 51‒58 View FIGURES 59‒63 )

Redescription of larva based on larval exuvia. Epistomal margin ( Fig. 51 View FIGURES 51‒58 ) not projecting above anteclypeal base and additional carina above epistoma present; upper boundary weakly carinate and irregular and lower boundary almost straight, arched; three pairs of epistomal setae; three long setae near postcondylar area and four on pleurostoma. Antennae ( Figs. 52, 53 View FIGURES 51‒58 ) short, extensible, sclerotized with antennifer membranous and two elongate antennomeres: antennomere basal ventrally with two campaniform sensillae; distal antennomere obliquely truncate apically, ventrally with seven campaniform sensillae, and at apex, one elliptical flat sensorium, four long setae and nine small cupuliform appendices. Clypeus ( Fig. 51 View FIGURES 51‒58 ) band-shaped, trapezoidal and membranous. Labrum ( Fig. 51 View FIGURES 51‒58 ) subelliptical, soft, convex, continuous ventrally; sclerotized on basal third; stout and long setae more concentrated on distal 2/3. Epipharynx ( Fig. 56 View FIGURES 51‒58 ) densely covered with setae directed to middle; basal region with pores near middle; one sclerite on each side near base. Mandibles ( Figs. 59–62 View FIGURES 59‒63 ) strongly sclerotized, symmetrical, wide; distal margin declivous, gouge-shaped; apical internal half with two inclined irregular keels; a wide dorsal subapical tooth; external margin with a transverse, semicircular depression near distal third, irregularly striate and rugose on distal half, and with sparse yellowish on basal half. Maxillolabial complex ( Figs. 54, 55 View FIGURES 51‒58 ) partially membranous; submentum, maxillary articulating areas and cardines fused, forming basal part. Distal maxilla: stipes with brown, inclined and irregular area near base, bearing long setae, more concentrated near margins; maxillary articulating area with moderately long setae; mala wide with rounded apex, bearing inclined sclerotized band near base and numerous long setae dorsal and ventral. Palpifer membranous with sclerotized ventral basal band, and numerous long setae dorsal and ventrolateral. Maxillary palpi trimerous; palpomeres partially sclerotized; basal palpomere transverse with three dorsal long setae near apex; median palpomere elongate with three ventral and dorsal setae; distal palpomere elongate with three ventral campaniform sensillae, and numerous peg-shaped sensillae at apex. Distal labium: mentum wider than long with lateral margins rounded; numerous long setae laterally; median region with barely sclerotized area with two setae and several darker small patches; one narrow irregular sclerite on each side of basal half. Prelabium with basal sclerotized irregular band projecting behind palpiger band; five campaniform sensillae between palpigers; several long setae on palpiger; numerous moderately long setae distributed on entire area, except basal region; setae more concentrated apically. Labial palpi dimerous and partially sclerotized; palpomeres elongate; palpomere basal with three small campaniform sensillae; palpomere distal with peg-shaped sensilla at apex. Hypopharynx ( Fig. 55 View FIGURES 51‒58 ) covered by stout setae with microspines at base. Spiracles elliptical ( Fig. 58 View FIGURES 51‒58 ).

Pronotum with transverse anterior yellowish band with ferruginous pubescence shorter near coxosternum; pubescence yellowish short and dense. Leg ( Fig. 57 View FIGURES 51‒58 ) partially sclerotized, except coxa, membranous; 4-segmented: coxa short and wide with one seta and two campaniform sensillae; femur robust, wider than long, with numerous long and wide setae near distal middle; tibiotarsus elongate with numerous long and wide setae; pretarsus elongate, glabrous and tuberculate.

Abdomen: segments I–VIII with a pair of elliptical spiracles; shorter than thoracic spiracles, decreasing in size toward apex; first abdominal spiracle larger; segments I–VII each with one ambulatory ampullae dorsal and one ventral; ampullae without spines.

Description of pupa, based on pupal exuvia. Abdominal tergites with band of microspines, increasing in size apicad; segment IX with band of microspines at apex (without urogomphi); tergites II–III, III–IV, IV–V, V–VI each with one pair of gin traps; seven functional elliptical spiracles decreasing in size apicad.
