Limnocoris hintoni La Rivers 

( Figs. 4View FIGURE 4, 6View FIGURE 6 C–D, 20A)

Limnocoris hintoni La Rivers, 1970: 3–4  (original description).

Limnocoris hintoni: La Rivers 1971: 75  (catalog); Nieser & López-Ruf 2001 (318: catalog).

Diagnosis. The distal margin of the labrum is distinctly acuminate ( Fig. 4CView FIGURE 4). The mesosternal carina has a small projection between the anterior projection and fossa ( Fig. 4EView FIGURE 4); the fossa is subtriangular, the anterior margin is shallowly concave and the lateral margins converge posteriorly; a small aperture is situated in the anterior region ( Fig. 4CView FIGURE 4); a small notch is posterior to the fossa in lateral view ( Fig. 4EView FIGURE 4). The male mediosternite VIII has a medial notch on the posterior margin (as in Fig. 18BView FIGURE 18).

Measurements (n = 5 males / 5 females). Body length 7.22–7.92/ 7.60–8.22, body width 5.17–5.65/ 5.40–5.72, synthlipsis 1.30–1.45/ 1.30–1.46, head length 1.20–1.25/ 1.10–1.20, head width 2.43–2.66/ 2.45–2.60, pronotum length at midline 1.45–1.50/ 1.45–1.60, pronotum width 4.30–4.90/ 4.40–4.80, scutellum length 1.15–1.23/ 1.20– 1.40, scutellum width 2.15–2.70/ 2.30–2.80, hemelytra length 5.40–5.90/ 5.60–6.20.

Supplemental description. Maxillary plate tumescent anteriorly. Antenna not exceeding lateral margin of eye; pedicel quadrate; flagellomeres slender, not partially fused, with long setae. Propleura with pubescent area distinctly extended posteriorly on lateral margin; convex medially; posteromesal corner near prosternellum deflexed ventrally. Region between mesobasisternum and mesoepisternum with longitudinal row of elongate golden setae ( Fig. 4CView FIGURE 4). Metasternal carina with fossa rounded, slightly depressed medially; posterior margin excavated in lateral view ( Fig. 4EView FIGURE 4). Lateral margin of abdomen with minute serration; posterolateral corners of II–V narrowly rounded to right angled, not spinose. Sterna with elongate golden setae generally dispersed, concentrated at midline of segments III–VI; sternum II with sinuous row of golden setae. Male: mediotergite VI with accessory genitalic process poorly developed; posterior margin with small notch on left side; posterior margin of mediotergite VII convex; laterotergite VII with lateral and mesal margins subparallel ( Fig. 6CView FIGURE 6). Lateral lobe of tergum VIII concave in anterior half of lateral margin; left medial lobe angled laterally at apex, distal margin rounded; right medial lobe twisted in distal third ( Fig. 6DView FIGURE 6). Female: lateral margins of subgenital plate convergent in posterior half, with tuft of elongate golden setae at mid-length; laterosternite VII evenly converging posteriorly ( Fig. 4DView FIGURE 4).

Variation. In the mesosternal carina, the lateral margins of the fossa can approach either other anteriorly without coming into contact, leaving a narrow elongated separation.

Comparative notes. This species is morphologically similar to L. inornatus  and L. pygmaeus  . These species share the color and pubescence patterns of the body, and shape of the distal margin of the labrum and posterior margin of the female subgenital plate. However, in L. hintoni  the lateral margins of the fossa of the mesosternal carina do not touch each other, the anterior region has a small aperture, and the lateral margin of male tergum VIII is concave; whereas in L. inornatus  and L. pygmaeus  , the lateral margins of the fossa of the mesosternal carina touch each other, the posterior region of the fossa has a small aperture, and the lateral margins of male tergum VIII are straight.

Distribution. This species is known only from Mexico and the records are concentrated in the Transmexican Volcanic Belt biogeographic province ( Fig. 20AView FIGURE 20). Probably this species is also distributed to the north and south of the previous records.
