Gregarious, reared from Carystoides basoches , C. escalantei , C. hondura , C. orbius , Carystoides Burns01, Carystoides escalanteiDHJ02 on at least 10 palm species ( Arecaceae ). A previous host record, Cobalopsis sp. on Oryza latifolia ( Deans et al. 2003 ) could not be confirmed. Figure 52.

Notes. Based on the material studied, A. nanosoma could include a complex of species (all comparatively of smaller size than most Alphomelon species). Pending the availability of more DNA barcodes from more specimens, especially from South America, we keep for now all known specimens within the same species. Figure 55.
