Hydrochus pertuberculatus Perkins 2020a: 297. Originallydescribed from Guatemala. Followingare new locality data records for Guatemalaand Mexico. Imagesof the habitus and male genitalia of the holotype, and detailed description of the male genitalia are given in Perkins (2020a).
Material examined (10): Guatemala: Peten, Parque National El Rosario, E of Sayaxche, ( 16°31’26.9’’N, 90°9’36.32’’W), 2-3.x.2013, leg. R. S. Zack(1 WSU). Mexico: Cotaxtla, Cotaxtla Exp. Sta., 1.vii.1962, leg. D. H. Janzen(1 NMNH); Chiapas, 5 Mi. S. Las Cruces, 23.viii.1965, leg. Paul J. Spangler(3 NMNH); Veracruz, 20 mi.NW Rt.144 Huatusco, 28.vi.1963, leg. Robt. E. Woodruff(4 NMNH); Cordoba, 19 mi.NE, 1.vii.1952, leg. collector unknown (1 SEMC).
Differential diagnosis.Among Central American species, recognized by the combination of moderately large size (ca. 3.56 mm), the moderately low and relatively impunctate pronotal reliefs, the large tubercle of the 5 thinterstria, and the male genitalia. This species has a generalized Hydrochushabitus; reliable determinations will require dissection of males. The male genitalia are superficially somewhat similar to that of H. nayaritensis n. sp., in being slender and having a very narrow aedeagus; however, the parameres, especially the sagittate tips, the basal piece shape, and the adbl shape and size are very different in H. pertuberculatus.
