Limnocoris panamensis La Rivers, 1970: 6–8(original description). Limnocoris panamensis: La Rivers 1971: 76(catalog); Nieser & López-Ruf 2001: 319(catalog); Herrera2013: 227(catalog).
Diagnosis.The pubescent area of the propleuron is not extended posteriorly on the lateral margin (as in Fig. 1D). The fossa of the mesosternal carina is distinctly deep and elliptical to ovate ( Fig. 13C). The metasternal carina is depressed medially, and acuminate posteriorly ( Fig. 13C). 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. 13D).
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. 13C); posteromesal corner near prosternellum flat. Region between mesobasisternum and mesoepisternum with longitudinal row of elongate golden setae (partially visible in Fig. 13C). 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. 14E). 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. 14F). Female: subgenital plate with posterior margin broadly convex; laterosternite VII with posterior margin shal- lowly angled to rounded apex ( Fig. 13D). FIGURE 13.

Size bar = 1.00 mm and applies only to Figs. A–B. FIGURE 14.Structures of male terminalia. (A, C, E) 6th and 7th abdominal terga, (B, D, F) 8th abdominal tergum. (A–B) Limnocoris moapensis, (C–D) L. nanus n. sp., and (E–F) L. panamensis. Comparative notes.This species has a characteristic mesosternal carina with a distinctly deep fossa. Five other species of Limnocorisshare a deep fossa of the mesosternal carina: L. angulatusNieser, González & Eichelkraut, L. bouvieriMontandon, L. caliiNieser, González & Eichelkraut, L. pectoralisMontandon, and L. virescens. Of these, only L. virescensoccurs in North America. In L. bouvieriand L. virescensthe posterolateral corners of abdominal segments III–V are spinose, whereas in L. panamensis, L. angulatus, L. calii, and L. pectoralisthese corners are slightly acuminate to rounded, without forming spines. Limnocoris caliiand L. pectoralisdiffer from L. panamensisand L. angulatusby the pubescent area of the propleuron extended posteriorly, which does not occur in the last two species. Limnocoris panamensiscan be differentiated from L. angulatusby 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. angulatusthe 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. 20A). Label data suggest that L. panamensisoccurs in regions with elevations above 1,000 meters above sea level. Published records. Costa Rica: Chiriquí ( La Rivers 1970).
