252 Description. Total length 3.2–5.3 mm, standard length 3.0– 4.8 mm; body rhomboid oval ( Fig. 19 ), derm blackish brown, scales elongate, dingy white to light yellow; prosternal channel absent; elytral apices round leaving apex of pygidium exposed. Male: rostrum curved moderately at base, distal portion curved less ( Fig. 24 ), anteantennal portion 0.33–0.37X length of rostrum; scape lamellate and gradually widened ( Fig. 13 ), first desmomere at least 1.5X longer than second, distal desmomeres increasingly asymmetrical, dorsally expanded and lamellate, club with basomere excised and with distinct conical process (as in Fig. 7 ); metatibia often with subdistal tooth on ventral margin above corbel ( Fig. 4 ); tarsomeres normal, without specialized setae; apex of aedeagus pointed, basal portion of internal sac one-half as long as apodemes, without obvious longitudinal folds ( Fig. 31 ), median and distal portions with armature consisting of numerous anvil-shaped, 65–90 Mm long denticles. Female: rostrum curved abruptly at base, distal portion nearly straight ( Fig. 28 ), glabrous, entire flank with fine but distinct punctures, anteantennal portion 0.44–0.46X length of rostrum; first desmomere at least 1.5X longer than second, club short-ovate, approximately as long as first desmomere; tibiae normal, without additional subdistal tooth.

Distribution. Coastal regions of southeastern United States (North Carolina, South Carolina, Georgia, Florida, Alabama), Arkansas, Missouri, Oklahoma, Texas ( Fig. 33 ).

Temporal occurrence. End of May to early October; December [1 date], February [1 date].

Plant association. Asclepiadaceae : Asclepias tuberosa (2X). Asteraceae : Arnoglossum atriplicifolium [as Mesadenia tuberosa ] (2X), Helenium sp. (71X), H. vernale [as H. nuttallii ] (2X), Heterotheca sp. (6X), Rudbeckia hirta (14X), ‘‘ Compositae flower’’ (1X). Euphorbiaceae : Croton sp. (1X), C. agyranthemum (4X). Fabaceae : Parosela sp. (1X). Lamiaceae : Monarda citriodora (2X). Lythraceae : Lagerstroemia indica [as crepe myrtle] (1X). Poaceae : Andropogon glomeratus (2X). Solanaceae : Solanum elaeagnifolium (7X), S. torreyi (2X).

Specific epithet. A compound Latin adjective composed of calcar (5 spur) and fero (5 to bear).

Discussion. This is a cryptic, possibly halophilous species near O. salebrosus . Males of both species often possess a subapical tooth on the hind tibia and share with most congeners the apically pointed aedeagus. They can be distinguished by the shape of the scape. Female specimens can be recognized by the elongate first desmomere, the subtle but usually distinct lateral punctures on the rostrum, the slightly compressed scape, and possibly habitat data.
