Subgenus Peucestes Stål, 1874

Type species (in original binomen): Peucestes coronatus Stål, 1874 , by subsequent designation ( Kirby 1906).

Brief diagnosis. This subgenus very similar to subgenus Steirodon (including characters listed here in Steirodon View in CoL s. str. diagnosis under numbers 1–3, 5, 6; Figs 6, 9, 10, 11, 13, 15 View Figs 1–15 , 46–49, 51 View Figs 38–57 ) and distinguished from it by only one character (number 4): tegmina with anterior branch of RS ending significantly before tegminal apex (i.e., in anal edge of tegmen; Figs 18, 19, 21, 22 View Figs 16–23 ).

Composition (in original binomens). Peucestes coronatus Stål, 1874 (described from Mexico); P. dentatus Stål, 1874 View in CoL (described from Panama, distributed from Costa Rica to Colombia and Venezuela); P. championi Saussure et Pictet, 1898 View in CoL (described from Guatemala, distributed also in Nicaragua and Costa Rica); P. latipennis Saussure et Pictet, 1898 View in CoL (described from Mexico); Steirodon (Peucestes) careovirgulatum Emsley, 1970 View in CoL (described from Panama, distributed from Costa Rica to Ecuador); S. (P.) para sp. nov.; possibly P. striolatus Brunner-Wattenwyl, 1878 View in CoL (described from Northeast Brazil and Panama), P. unidentatus Brunner-Wattenwyl, 1878 View in CoL (described from Peru) and P. emarginatus Brunner-Wattenwyl, 1891 View in CoL (type locality unknown).

These species (except for S. para sp. nov., S. striolatus View in CoL and S. unidentatus View in CoL ) were attributed to this subgenus by Emsley (1970), but he did not include some species ( S. latipennis View in CoL and S. emarginatus View in CoL ) in his key to species of Peucestes View in CoL . And two species ( S. striolatus View in CoL and S. unidentatus View in CoL ) were placed in this subgenus in OSF, although Emsley considered the first name as a synonym of Cnemidophyllum (Eupeucestes) citrifolium (Linnaeus, 1758) View in CoL .
