Hypseloecus castaneus sp. nov.

( Figs. 2 View FIGURE 2 B–C, 3, 5– 7)

Diagnosis. Distinguished from other congeners by its brown to castaneous body often tinged with red; broad head, with reddish striae on frons ( Fig. 5 View FIGURE 5 ); and color pattern of coxae ( Fig. 6 View FIGURE 6 , Table 1 View TABLE 1. A ).

Description. Male. COLORATION AND VESTITURE: Body generally pale brown, often partly tinged with orange-red or maroon; dorsal surface brown to castaneous, with densely distributed, reclining scalelike setae. Head pale brown, rather shining, with red striae on frons; clypeus with sanguineous stripes laterally. Antenna uniformly pale or yellowish brown; segment I sometimes tinged with red. Labium shiny pale brown. Pronotum usually chestnut brown; pleura as in Fig. 6 View FIGURE 6 ; ostiolar peritreme yellowish white. Hemelytron brown or chestnut brown; membrane grayish brown, with pale veins and irregular, pale, semitransparent portion at middle. Coxae as in Table 1 View TABLE 1. A . Leg whitish or yellowish brown; each femur mottled with red-orange maculae; all tibiae with obscure, reddish brown annulations. Abdomen pale to reddish brown. STRUCTURE: As in generic description (see Schuh & Menard, 2011). Genitalia ( Fig. 3 View FIGURE 3 ): Endosoma J-shaped, with a median process. Female. Similar coloration and structure to male.

Measurements. ♂/♀: Total body length 2.2−2.4 / 2.3−3.1; length from apex of clypeus to cuneal fracture 1.74 −2.00/ 1.90−2.30; width of head across eyes 0.91−1.05 / 0.94−1.08; head height 0.60−0.64 / 0.62−0.64; width of vertex 0.49−0.51 / 0.51−0.60; lengths of antennal segments I −IV 0.19−0.24, 0.73−0.90, 0.36−0.39, 0.38−0.50 / 0.20−0.24, 0.72−0.96, 0.39−0.44, 0.42−0.54; basal width of pronotum 1.08−1.19 / 1.08−1.31; maximum width across hemelytron 1.21−1.44 / 1.33−1.59; and length of metatibia 1.20−1.42 / 1.20−1.56.

Etymology. From Latin, castaneus (= chestnut or castaneous brown), referring to the general coloration of this new species.
