Etymology: The name refers to the yellow spots present on the body surface.

Latin = luridus, pale yellow; macula, spot.

Paratype: female. PANAMA, Colon: (Parque Nac. Soberania: Pipeline Rd Km 0 - 4.609º 07’N 79º 45’W), 19.v.1995, J. Jolly. G. Kidd, C. Chaboo & B. Haylord (KSBS). Deposited in: KSBS.

Description. Dark brown to black. Lateral of pronotum and basal half of corium outlined in yellow. Large yellow spots on the body: three basal spots and two apical on scutellum, one at apex of each radial vein of hemelytra, and one central spot in each connexival segment, continued ventrally. Coxae, trochanter, femora and tibiae dark castaneous; tarsi yellowish ( Fig. 3E, F ).

Male. Measurements (n=1): head length 2.76; width 3.24; pronotum length 3.40; width 6.24; scutellum length 5.22; width 4.04; abdomen length 5.39; width 6.39; length of antennal segments: I 1.20; II 1.24; III 2.00; length of labial segments: I 1.75; II 3.15; III 2.75; IV 2.70; total length 13.41

Genitalia. Pygophore subglobular, castaneous; posterolateral angles moderately divergent, yellowish, stout, posteriorly depressed, apices obtuse. Parameres yellowish, subparallel to posterolateral angles, surpassing the apex of segment X, flattened digitiform, base cylindrical and apex expanded terminating with an apical tooth-like projection on lateral margin. Segment X subcylindrical, basal portion membranous forming a concave line on the limit of the sclerotized area ( Fig. 5G–I ).

Female. Measurements (n=1): head length 2.90; width 3.40; pronotum length 3.78; width 6.74; scutellum length 5.79; width 4.47; abdomen length 6.39; width 6.95; length of antennal segments: I 1.40; II 1.28; III 2.00; VI 2.20; V 2.60; length of labial segments: I 1.80; II 3.25; III 2.75; IV 2.80; total length 14.50

Genitalia. Gonocoxites VIII oval, longer than wide, covering the base of laterotergites IX, posterior margins over gonocoxites IXrectilinear. Laterotergites IX digitiform, directed diagonally to apex ( Fig. 8C ).

Distribution: PANAMA.
