Abstract
American Pseudophasmatinae stick insects are often colorful, winged or apterous, with or without scale-shaped tegmina, with an area apicalis on all tibiae, and either with a ventromedian carina on the meso and metafemora, or with broad profemora, as long as head, pro- and mesonotum combined (Zompro, 2004). In the egg, micropylar plate is externally located in the middle of the dorsal surface, and internally appears of the open type. Among Pseudophasmatinae, the genus Tithonophasma Zompro, 2004 has a single species, Tithonophasma tithonus (Gray, 1835). Although this species is frequent in museum collections (Zompro, 2004), accurate morphological and biological information potentially useful in phylogenetic approaches are still missing.
