Body oval—elongate, widest at fifth or sixth segment. Integument chiti- nous, transparent, thick, covered with numerous flattened roughly elliptical granules (Fig. 4c). Membranous subintegumental layer bearing branched chro- matophores. Head (Fig. 1) evenly convex, bearing two compound eyes dorso- first antenna frontal labr. econd antenna clypeus mandible maxilliped Fig. 1. Tylos granulatus. Anterior view of head. laterally, each composed of about 50 ommatidia. No distinct frontal line, but faint impressed line joining anterior margins of eyes, becoming obsolete mid- dorsally. Vertex narrowed antero-ventrally between first antennae, giving way to broadly rounded frontal process. Broad clypeus below frontal process, with labrum ventrally attached. Labrum asymmetrical due to underlying left mandi- ble atop right mandible. Narrow gena situated lateral to second antennae, ven- trally embracing mandibular bases. Head appendages—first antenna consisting of single almost immobile segment medio-dorsal to second antenna, dorsally flattened, triangular, level with rest of vertex, ventrally with broad articulating area, with socket-like depression near apex of triangle, containing numerous aesthetascs. Second antenna (Fig. 2c) stout, elongate, consisting of five basal segments plus flagellum.
