[email protected] Abstract Th e chilopod subfamily Ectonocryptopinae (Scolopocryptopidae) comprises rarely-encountered, small- bodied scolopendromorphs known only from Mexico and Belize. Th ree species have been described, one in Ectonocryptops Crabill, 1977, and two in Ectonocryptoides Shelley & Mercurio, 2005. External charac- ters ally this clade with the speciose Neotropical subfamily Newportiinae. Scanning electron microscopic documentation of the mouthparts, peristomatic structures and foregut in Ectonocryptoides quadrimeropus Shelley and Mercurio, 2005, together with new data for Newportia, enable analysis of ectonocryptopine relationships based on the current character set for scolopendromorph phylogeny. A distinctive “pineap- ple-shaped” gizzard projection strengthens the alliance between Ectonocryptopinae and Newportiinae, which group together as a well-supported clade that
