Paramiridius laomontanus sp. n. Figs 1, 2, 3, 4

Diagnosis.

Recognized by the characters in the key, and the modified shape of the parameres (Fig. 2), and the well-developed lateral lobe and short spicule on the endosoma (Fig. 3). By these characters, Paramiridius laomontanus can be readily distinguished from other congeners.

Description.

Coloration: Body yellow, often tinged with green, with black maculae and stripes. Head yellow, with paired, symmetrical, dark maculae on vertex; frons with a black stripe medially; clypeus darkened basally. Antenna dark brown to black; extreme bases of segments II and III white. Labium dark brown, except for yellowish segment II. Pronotum greenish yellow, with three pairs of black stripes not reaching pale posterior margin of pronotum. Mesoscutum and scutellum yellow, with symmetrical, dark patterns. Hemelytron pale green or greenish yellow, with variable black patterns as in Fig. 1; inner margin of clavus, and apical half of embolium blackish brown. Coxa pale yellowish brown, with a dark spot basally; leg yellowish brown; pro- and mesofemur with dark brown spots; apex of each femur more or less darkened; all tibiae and tarsi dark brown.

Structure and vestiture: Body rather ovoid; dorsal surface with sparsely distributed, simple, pale, short setae. Eye small, contiguous to pronotal collar; vertex wide. Antenna generally slender. Labium comparatively broad, extending to apex of mesocoxa. Pronotum rather tumid, not carinate laterally. Hemelytron shallowly and roughly punctate, almost glabrous.

Male genitalia (Figs 2, 3): Parameres glabrous; left paramere slender and nearly straight, with a protuberance at middle and an apically hooked hypophysis; right paramere simple (Fig. 2). Endosoma with a broadened, thin spicule, a tapered median lobal sclerite, and an apically developed, brush-shaped lateral lobal sclerite (Fig. 3).

Female genitalia (Figs 2, 4): Bursa copulatrix similar to that of the preceding species, but dorsal labiate plate more developed (Fig. 4). Posterior wall of bursae with rounded interramal sclerite and rather broadened interramal sclerite (Fig. 2).
