The midguts and proventriculi of three Pyncoscelus spp. from the Philippines are described. Each group of gastric caeca and proventriculus was dissected and analyzed. The number of gastric caeca varies per species, but all have two long gastric caeca. Results showed that P. sp. Nr. Surinanmensis (L.) was distinct from the P. indicus (Fabricius) and P. striatus (Kirby). Similarities and differences of P. indicus and P. striatus were also noted. Differences between sexes of P. indicus and P. striatus are observed. The selected mitgut characters can be useful in identification but may not be phylogenically meaningful.
