description: Immatures of Psapharochrus
Based on three studied species (P. cylindricus, P. j a s pi de u s, P. vetustus) and on the descriptions of three others (P. juno, P. lateralis, P. melanosticticus), the larvae of Psapharochrus are recognized by having head oblong, moderately flattened, widest anteriorly, with sides slightly constricted before middle except P. melanosticticus and P. vetustus; frontal sutures distinct only behind antennal foramina; three pairs of epistomal setae, except P. melanosticticus, with two pairs; lateral pair of epistomal setae very close in studied species; antennae with two antennomeres: distal, with a conical sensorial appendix and 7 setae; labrum slightly testaceus, transversely oval with fringe of bristly setae; gular suture distinct and with one pair of setae each side; occipital foramen entire, with anterior margin slightly rounded except P. j un o, 6-angulated; clypeus trapezoidal, 3.0-3.3X wider than long; labrum oval, 1.1‒1.9X wider than long; pronotum with anterior half or third covered with moderately long and dense erect setae, without median line; posterior half microrugose or microtuberculate; postnotal fold indistinct; eusternum tuberculate; mesonotum smooth; meso- and metasternum and metanotum with one transverse furrow with one row of moniliform tubercles each side; moniliform tubercles microspiculate only in P. juno; segments VII‒VIII broader than previous, except P. melanosticticus; segments I‒VII with dorsal elliptic ampullae, decreasing in width from first to last; each dorsal ampulla bearing two transverse furrows and three rows of moniliform tubercles; ventral ampullae with one single transverse furrow and one row of moniliform tubercles each side; epipleural lobes with two sclerotized pits; epipleura strongly protuberant on segments VII‒IX; anus trilobate and sparsely setose.
The pupae have head partially visible dorsally, with eight pairs of spines; one pair of spines near base of each antennal tubercle; clypeal area with four short spines, each with basal setae; antennae not reaching abdomen or at maximum reaching ventrite II, where they are strongly curved and directed anteriorly; labrum subtriangular, almost glabrous, with single row of five short spines with basal seta, glabrous in P. melanosticticus; each mandible with two setae near middle of outer face, with single seta in P. j un o. Prothorax with one pair of long, acute, lateral tubercles with or without spines at apex; disc with one pair of paramedian hemispheric tubercles; numerous short spines at anterior margin, apically and basally lateral tubercles and behind dorsal tubercles; meso- and metanotum with two oblique rows of spines, each with basal seta; elytra and wings glabrous, extending as far as ventrite II. Abdomen: tergites with transverse bands (interrupted medially) of short spines, directed posteriorly, each with basal seta: segment I with single band and II‒VII with two bands; VII bearing, except transverse bands, numerous short spines; segment VIII very short with 4‒5 pairs of spines each side; IX with one pair dorsal and 3-4 spines each distal projection; segment X ventral and bilobed. All femora near apex with a transverse row of spines, each with basal long seta; mid and hind femora each with one long blunt tubercular process near base. Functional spiracles on segments I‒VI; VII closed.
