Diagnosis. Larva: It is similar to those of P. abdominalis , P. cressae , and P. passulatus , by the pale brown to yellow color of the head, with dorsal and lateral muscle scars very evident. It differs from that of P. fenestratus which has a uniformly brown head with the dorsal and lateral muscle scars not conspicuous. It is similar to that of P. passulatus in that the spines on the ventral margin of each foretrochantin are short, whereas in P. fenestratus each foretrochantin has strong and prominent spines on the ventral margin. It differs from known larvae of the other species by having the anterolateral processes of the pronotum without curvature, gradually tapering to pointed apices; in P. fenestratus this process has a broad base and a pre-apical region with a rounded and convex lobe, in P. passulatus the process has a narrow base and a pre-apical region with an undeveloped lobe, in P. cressae ( Barrios et al. 2020) the anterolateral extensions of the pronotum are elongate as a pair of strong sclerotized hooks, and in P. obliquus ( Cavalcante et al. 2020) the anterolateral margins are strongly projected with apices hooked anteroventrad. It also differs in that it has legs light yellow, with a brown band in the median region of each femur, tibia, and tarsus, while in P. fenestratus they are dark brown without bands, and in P. passulatus , the legs are uniformly light brown.
Case: It is flat, constructed with two leaf fragments, oval in shape, with the dorsal fragment larger than the ventral one, similar to the case of P. lituratus ( Rueda Martín 2013) . It differs from the flat cases of P. passulatus , P. mexicanus ( Wiggins 1996) , and P. abdominalis ( Huamantinco et al. 2005) which are constructed with 3 to 4 rounded or rectangular leaf fragments on each side. The case of P. fenestratus , although formed by 3 to 4 rounded or rectangular leaf fragments on each side, is not flat.
Pupa: It differs from those of the other species by the number of setae on the median lobe of the labrum, with 16–18 median setae. That of P. fenestratus has 20–22 long setae on this lobe, that of P. passulatus has 24–26 long setae, that of P. abdominalis has 24 setae, and that of P. obliquus has 24–28 long setae ( Cavalcante et al. 2020). Phylloicus amazonas differs also in the high number of setae (30) distributed throughout the the length of each anal process; P. fenestratus , P. camargoi ( Quinteiro et al. 2011) , and P. passulatus each have 1 long sub-basal and 3 short apical setae on each process and that of P. abdominalis has only 3 short apical setae on each process ( Huamantinco et al. 2005).
