Scalponotatus capitatus Kelton, 1969: 22 , fig. 10 (orig. desc.); Schuh, 1995: 194 (catalog).

DIAGNOSIS: Recognized by the small size, the contrasting coloration being predominantly pale yellowish brown, except for the usually brown to dark brown antennal segment II, distally, segment II and IV, pronotum, on the posterior margin, scutellum, hemelytron, and abdomen; sometimes coloration completely pale yellowish brown; the moderately dense, golden simple setae; and the male genitalia as in figure 8.

REDESCRIPTION: Male: Small, moderately ovate; length 2.50–2.95, width 1.25–1.88 (pl. 1). COLORATION: Body generally shining, contrasting pale yellowish brown and dark brown or sometimes completely pale yellowish brown; head pale yellowish brown to orange-brown, with base, or entire clypeus and adjacent mandibular plate sometimes diffusely darker; labial segment IV brown; antennal segment I and II basally pale yellowish brown, segment II distally, and segments III and IV brown. Pronotum, except for variable posterior margin, side of thorax, including evaporative area, legs, except for tarsomere III, pale yellowish brown; dark brown on variable portion of posterior margin of pronotum, or more extensively on disc, scutellum, tarsomere III, hemelytron, including membrane, and abdomen dark brown; sometimes entire body pale yellowish brown, except for hemelytral membrane dusky and labial segment IV and tarsomere III dark brown. VESTITURE: Moderately dense, short, golden, reclining simple setae, about as long as diameter of antennal segment II. DORSAL SCULPTURATION: With dense, minute, discrete punctures, underlying broad shinglelike plates. GENITALIA: Pygophore: Tergal process broad, low and medially situated (fig. 8H). Phallotheca: Aperture large, open broadly on right side; distally without thickening or concavities (fig. 8B). Endosomal spicule: Membrane attached to flat basal keel; subapical bifurcation of spicule flattened and subtriangular, rami at bifurcation of conspicuously unequal length, short ramus pointed, long ramus recurved, with bifurcate apex reaching to secondary gonopore; dorsal lobe narrow, curving perpendicular to ventral lobe of spicule (fig. 8A). Right paramere: Cshaped, with large apical and basal processes (fig. 8E–G). Left paramere: Attenuate distally, terminating in narrow apex (fig. 8C, D).

Female: Small, more ovate than male; length 3.00–3.30, width 1.55–1.80 (pl. 1); coloration as in male. GENITALIA: See description of genus.

HOST PLANT: Unknown.

DISTRIBUTION: Known from the lowland dry forests west of the Sierra Madre Occidental in central and southern Sinaloa, Mexico ( map 1 View Map 1 ).

DISCUSSION: As discussed in the preceding species treatment, S. capitatus does not have the defining characters of Scalponotatus as redefined herein, but is accommodated within the diagnosis of Josephinus , into which it is transferred forming a new combination. Specimens from 26 mi N of Pericos, the most northerly records examined, do not have contrasting pale and dark coloration, but are completely pale yellowish brown or pale orange-brown. The male genitalia are identical to those of the holotype and other topotypic specimens.
