Eburia pseudostigma Lingafelter & Nearns , new species

( Figs. 1e , 2a )

Description. Moderate size, 18–22 mm long; 4–5 mm wide at humeri; integument dark brown, but mostly covered with tawny brown pubescence. Head with shallow, evenly concave interantennal tubercle region; tubercles only weakly elevated. Head (including antennal tubercles) not conspicuously punctate, mostly covered with tawny brown pubescence above; ventrally glabrous except anterior region of gula, punctate or rugose posterior of lower eye lobes. Pubescence of head short, appressed, except for few scattered long hairs at anterior margin of frons and throughout anterior half of gula. Eyes large, coarsely faceted (about 26 facets at greatest height of lower lobe; 7 facets across width of upper lobe), deeply emarginate at insertion of antenna, lower lobe occupying most of head thickness. Antenna without spines, with vestiture of short, tawny brown pubescence, with longer hairs at apex of most antennomeres and a ventral, mesal fringe of longer hairs throughout. Antennomeres not darkened at apices. Antennae of males surpassing elytra by about 4 antennomeres; antenna of females by about 2 antennomeres. Pronotum length slightly more than width with one acute lateral tubercle on each side behind middle, and one on anterior of disk on each side of middle. Pronotum with large, alveolate punctures, mostly concealed by dense, appressed tawny brown pubescence. Discal tubercles with little pubescence and appearing as black spots from above. Prothorax sides without anterolateral glabrous calli. Prosternum of males with dense, large punctures, mostly concealed by dense tawny pubescence; females densely pubescent, but with small scattered punctures. Prosternal process moderately wide between procoxae, moderately expanded at apex; procoxal cavities open posteriorly. Elytra with dense vestiture of tawny pubescence, densely punctate except for sparsely punctate apical third; with 4 elongate ivory calli: two at base and two at middle. Middle outer callus elongate, about half length of elytron or longer, twice as long as inner callus at middle. Basal calli much shorter, inner callus at base nearly twice as long as outer callus at base. Each pair of calli adjacent to but not touching one another. Pubescence around calli sparse, exposing darker brown integument. Elytral apices strongly bispinose, outer spine approximately twice as long as sutural spine. Scutellum rounded posteriorly, densely tawny pubescent, without conspicuous punctures. Legs elongate, femora narrow, not expanded. Mesal meso- and metafemoral apices very strongly spinose, lateral apices weakly spinose. Profemoral apices rounded. Venter densely tawny pubescent throughout. Mesosternum with broad mesocoxal process with vague lateral extensions into mesocoxae. Fifth sternite of both sexes very broadly rounded, without modification.

Etymology. The specific epithet is a noun in apposition referring to the similarity to and possible confusion with the more common and widespread Eburia stigma (Olivier 1795) .

Discussion. The only species with which this can be confused is Eburia stigma (Olivier 1795) ( Fig. 1f ), which differs in having the lateral (outer) middle ivory callus of the elytron much shorter, about one fourth the length of the elytron or shorter; femoral spines shorter (the lateral [outer] meso- and metafemoral spines about twice as long as the mesal spines in E. stigma , but often over 3 times longer than the mesal spines in E. pseudostigma ); the punctation of the pronotum (especially females) not strongly alveolate; the pronotum about as wide as long; the prothorax with a distinct anterolateral glabrous callus on each side; and the antennomeres distinctly darkened at the apices.
