Genus Haplaxius Fowler, 1904 View in CoL View at ENA

Type species: Haplaxius laevis Fowler, 1904 View in CoL (type species designation by Caldwell 1946: 203)

Diagnosis (modified from Bahder et al. 2020). Small to average size cixiids (3.2–6.4 mm); head in dorsal view narrower than pronotum, eyes large (elongate-oval, diagonally truncate posteriorly, usually with ventral emargination at antenna); vertex elongate, moderately broad (among Oecleini ), vertex disc slightly concave, sides and apex carinate, median carina usually absent, apex variably produced beyond eyes (usually weakly projected). In lateral view, apex of head bluntly angled, ocellus beneath eye (anterior to antenna). In frontal view, sides of frons concave (“flared”) and carinate, midline of frons carinate, interrupted near frontoclypeal suture by ocellus (ocellus sometimes absent), clypeus subtriangular with lateral margins and midline carinate. Antennal scape reduced, pedicel robust, flagellum beadlike basally and filamentous distally. Pronotum narrow, with irregular ridges and distinct paranotal region, length shortest at midline, posterior margin indented; tegulae evident. Mesonotum tricarinate; longitudinal midlength of mesonotum about two times that of vertex. Hind tibiae without lateral spines. Forewings tectiform, usually hyaline or transparent, but sometimes infuscated or patterned, veins usually with small setae-bearing pustules (tubercles). Male pygofer usually longest on ventral margin, hind margin variably produced. Aedeagus asymmetrical and elaborated with projections and processes, vertical connective articulating base of aedeagus with gonostyli (genital styles). Gonostyli symmetrical and usually simple. Anal tube symmetrical or asymmetrical, with processes from one or both ventral margins and sometimes with median ventral projections.
