- davisi. Cerapachys (Parasyscia) davisi Smith, M.R. 1942b: 64 (m.) U.S.A. Combination in Acanthostichus: Brady et al., 2014: 6.
Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
The male holotype of davisi differs from the known males of Syscia augustae as follows: Size larger (3.8 mm.); posterior border of head rounded and merging into each side without forming as definite a subangular posterior corner; all funicular segments except first distinctly longer than broad (less incrassated than in augustae); pronotum almost one-half length of mesonotum; front wing with or without a closed cubital cell; veins more prominent and more nearly enclosing radial and cubital cell (when cubital cell is not completely enclosed); sculpture different, davisi having fine rugulae between inner border of eye and antenna, and similar rugulae on epinotum, especially the sides of epinotum; sixth tergite more coarsely sculptured, subopaquc; color dark brown, almost black.
The paratypes range in length from 3.8 to 4.2 mm.
Described from holotype and 3 paratype specimens, each bearing the label "Fort Davis, Tex., Jeff Davis County, 5000 feet, Davis Mountains, Mrs. O. C. Poling, Nov. 15, 1927." These have been assigned United States National Museum Number 56091.
