Tribe Callipogonini Thomson, 1861

The tribe Callipogonini is composed of 18 genera and 47 species ( Tavakilian & Chevillotte 2018). Immature stages of six species, each belonging to one genus, have been described: larvae and pupae of Callipogon barbatus (Fabricius, 1871) , ( Duffy 1960); larvae and pupae of Chorenta reticulata (Dalman, 1817) , ( Duffy 1960); larvae and pupae of Navosoma luctuosum (Schönherr, 1817) , ( Penteado-Dias 1982); larvae and pupae of Orthomegas cinnamomeus (Linnaeus, 1758) , ( Duffy 1960); larvae of Ctenoscelis ater (Olivier, 1795) , ( Duffy 1960); larva of Enoplocerus armillatus (Linnaeus, 1767) , ( Di Iorio et al., 1995); and larvae of Seticeros aquilus (Thomson, 1865) ( Casari & Santos-Silva 2010) .

Based on descriptions of the immature stages of these six species, the larvae of Callipogonini are characterized as follows: epistomal margin projected above clypeal base and additional carina above epistoma; upper boundary variable, almost straight, not projecting over lower boundary; lower boundary produced laterally into a pair of acutely pointed flattened teeth in most species, only carinate sublaterally ( Callipogon barbatus ; Orthomegas cinnamomeus ), into a pair of small paramedian lobes ( Ctenoscelis ater ) or with three tubercles on each side of median frontal line ( Enoplocerus armillatus ); epicranial suture without frontal branches, except Seticeros aquilus , visible in small area below antennae; median frontal line long; foramen occiput divided by tentorial bridge; antennae with two antennomeres except Enoplocerus armillatus and Seticeros aquilus , with three antennomeres; five pairs of stemmata except Navosoma luctuosum with four pairs (three subcontiguous) and Callipogon barbatus and Ctenoscelis ater with three pairs; legs 3-segmented except Seticeros aquilus 4-segmented; abdomen with retractile ambulatory ampullae, each with one pair of transverse furrows, without microspines; bilobed ampullae dorsally and ventrally; segment X trilobed; anal opening Y-shaped.

Based on descriptions of four species, the pupae of Callipogonini are characterized as having the following: head glabrous and visible from above except in Navosoma luctuosum , partially visible, and with a few setae at base of tubercles; mandibles glabrous except in N. luctuosum with a few setae; antennae extending as far as abdominal ventrite II or III where they are recurved ventrally; pronotum transverse, glabrous, without lateral tubercles and disc striate, except in N. luctuosum , grooved longitudinally and with some papillae and setae; meso- and metanotum glabrous and transversely striate ( Callipogon barbatus , Orthomegas cinnamomeus ), sparsely spinose ( Chorenta reticulata ) or with sparse setae ( Navosoma luctuosum ); elytra and wings extending as far as ventrites III or IV; abdominal tergites covered with scattered microspines; sternites with much finer microspines or glabrous; gin-traps on tergites II–III, III–IV, IV–V and V–VI; spiracles on abdominal segments I–VI; VII–VIII closed and non-functional; urogomphi absent.
