Syntames Fowler, 1905 ( Type species Syntames delicatus Fowler 1905 , by monotypy). Synonym with Herpis according to Muir 1924: 16 ; Caldwell 1944: 99 ; O’Brien 1987: 383 ; treated as valid by Metcalf 1938: 324 ; 1945a: 101 ; 1945b: 125 . Synonymy of Syntames with Herpis confirmed in Bahder et al. (2021a) . Amended Diagnosis (Modified from Bahder et al 2021a ). Relatively large, and robust cenchreines, measuring approximately 5-8 mm in length, including wings. Wings held tectiform in repose, distinctly exceeding abdomen. Vertex broad, trapezoidal, just broader than long, nearly flat to weakly concave, transverse carinae present at fastigium. Pits present along lateral carinae of vertex and frons, varying in distinctness, appearing to be in 2+ rows. Frons (frontal view) broad, flat or nearly so (not concave), lateral margins parallel, medium carina of frons evident, frontoclypeal margin straight. Clypeus elongate-triangular, approximately in the same plane as frons, median carina present. Genae without subantennal processes. Antennae short, pedicle spheroid, about as long as wide. Lateral ocelli obscure or absent. Pronotum narrow, anterior convex, posterior concave, broadening laterally, in lateral view declinate anteriorly; paranotal region foliate, forming large foveae posterior to the antennae (a tribal feature). Mesonotum tricarinate, carinae approximately reaching posterior margin, scutellum contiguous with scutum (i.e., not separated by groove). Lateral teeth absent on tibiae. Terminalia bilaterally symmetrical. Pygofer in lateral view narrow, irregular in outline; in ventral view, median process of pygofer present (longer than wide, apically conical). Gonostyli elongate, broad, bearing dorsal projection in proximal half, and (in ventral view) usually with a medial (ental) process near midlength. Aedeagal shaft with processes apically and near midlength; flagellum complex, with elongate retrorse processes. Anal tube elongate in lateral view (but usually shorter than gonostyli), distally expanded; in dorsal view appearing spatulate with caudal margin strongly bifid.
