Limnocoris panamensis La Rivers 

( Figs. 2FView FIGURE 2, 13View FIGURE 13, 14View FIGURE 14 E–F, 20A)

Limnocoris panamensis La Rivers, 1970: 6–8  (original description).

Limnocoris panamensis: La Rivers 1971: 76  (catalog); Nieser & López-Ruf 2001: 319 (catalog); Herrera 2013: 227 (catalog).

Diagnosis. The pubescent area of the propleuron is not extended posteriorly on the lateral margin (as in Fig. 1DView FIGURE 1). The fossa of the mesosternal carina is distinctly deep and elliptical to ovate ( Fig. 13CView FIGURE 13). The metasternal carina is depressed medially, and acuminate posteriorly ( Fig. 13CView FIGURE 13). The lateral margin of the female subgenital plate has a tuft of elongate golden setae at mid-length, and the posterior margin is evenly rounded ( Fig. 13DView FIGURE 13).

Measurements (n = 3 males / 3 females). Body length 8.20–8.23/ 8.60–8.74, body width 5.65–5.80/ 5.86–6.00, synthlipsis 1.49–1.52/ 1.50–1.51, head length 1.21–1.40/ 1.40, head width 2.75–2.80/ 2.80–2.82, pronotum length on midline 1.50/ 1.50–1.60, pronotum width 5.37–3.40/ 5.65–5.68, scutellum length 1.20–1.40/ 1.40, scutellum width 2.51–2.70/ 2.61–2.80, hemelytra length 5.90–6.12/ 6.20–6.40.

Supplemental description. Maxillary plate tumescent anteriorly. Distolateral margins of labrum tapering to broadly rounded point. Antenna not exceeding lateral margin of eye; pedicel quadrate; flagellomeres slender, not partially fused, with long setae. Posterior margin of propleuron convex at mid-length ( Fig. 13CView FIGURE 13); posteromesal corner near prosternellum flat. Region between mesobasisternum and mesoepisternum with longitudinal row of elongate golden setae (partially visible in Fig. 13CView FIGURE 13). Lateral margin of abdomen with minute serration; posterolateral corners of II–VI narrowly rounded to right angled, not spinose; sterna with elongate golden setae generally dispersed, concentrated at midline of segments III–V; sternum II with sinuous row of golden setae. Male: mediotergite VI with accessory genitalic process poorly developed; posterior margin of mediotergite VII convex medially, with small rounded lobe on each side; laterotergite VII with lateral and mesal margins subparallel, and posterior margin narrowly rounded ( Fig. 14EView FIGURE 14). Lateral lobe of tergum VIII with lateral margin almost straight in anterior half; left medial lobe slightly angled laterally at apex, distal margin rounded; right medial lobe twisted in distal third ( Fig. 14FView FIGURE 14). Female: subgenital plate with posterior margin broadly convex; laterosternite VII with posterior margin shal- lowly angled to rounded apex ( Fig. 13DView FIGURE 13).

Comparative notes. This species has a characteristic mesosternal carina with a distinctly deep fossa. Five other species of Limnocoris  share a deep fossa of the mesosternal carina: L. angulatus Nieser, González & Eichelkraut  , L. bouvieri Montandon  , L. calii Nieser, González & Eichelkraut  , L. pectoralis Montandon  , and L. virescens  . Of these, only L. virescens  occurs in North America. In L. bouvieri  and L. virescens  the posterolateral corners of abdominal segments III–V are spinose, whereas in L. panamensis  , L. angulatus  , L. calii  , and L. pectoralis  these corners are slightly acuminate to rounded, without forming spines. Limnocoris calii  and L. pectoralis  differ from L. panamensis  and L. angulatus  by the pubescent area of the propleuron extended posteriorly, which does not occur in the last two species. Limnocoris panamensis  can be differentiated from L. angulatus  by having the posterolateral corner of the pronotum rounded in brachypterous specimens, male abdominal tergum VIII with the right medial lobe twisted in the distal half, and the female subgenital plate with the posterior margin broadly rounded; whereas in L. angulatus  the posterolateral corner of pronotum is acute, male abdominal tergum VIII with the right medial lobe weakly twisted, and the female subgenital plate tapering posteriorly and the posterior margin truncate medially.

Distribution. This species is distributed from northern Costa Rica (Guanacaste) to the central region of Panamá (Veraguas) ( Fig. 20AView FIGURE 20). Label data suggest that L. panamensis  occurs in regions with elevations above 1,000 meters above sea level.
