Rhytidaspis genyem sp. n. Figs. 1L, 2P, 11G, L, V Holotype (female): Indonesia, Papua: 40 km W. of Hollandia [Jayapura], Genjam [Genyem, Gengen, 2°46’S, 140°12’E], elev. 100–200 m, 1–10.iii.1960, leg. T.C. Maa—(Honolulu, BPBM). Diagnosis. R. genyem sp. n. is only known from a female. It differs from females of other species of the genus by the subgenital plate that has the basal, lateral angles of the ventral plate distinctly produced laterally and the ascending lateral areas of the subgenital plate are almost completely membranous except for the stiffened upper margin in more basal area. In other species of the genus the ventral area of the female subgenital plate has more regularly approaching lateral margins and the ascending lateral areas are partly strengthened. The green face differs so far known from the coloration in all other species. The pale instead of black antennal scrobae, scapus and pedicellus and the faintly expressed black transverse strokes on the femora it shares only with R. nigropunctata sp. n., from which it differs however by the green instead of black doted face and by the pale fastigium verticis (Fig. 2P). Description. Fastigium verticis up-curved and laterally compressed, with faint tubercles at dorsal margin in subbasal area, tip acute; on ventral side separated from fastigium frontis by a step; length of fastigium verticis before eyes 3 mm; dorsal eye length 2.0 mm, greatest eye diameter 2.2 mm. Female. Subgenital plate ventral surface widened at base, then distinctly constricted and with converging lateral margins, towards tip strongly up-curved and split into two short acute lobes; lateral surfaces largely membranous with stiffened margin, almost reaching tip of ventral surface (Figs. 11G, L, V). Ovipositor elongate, in about basal half sub-straight with parallel margins, in apical half slightly up-curved with approaching margins to acute tip. Ventral ovipositor valves at very base with large elongate swellings that are in situ hidden by the subgenital plate (Fig. 11L) Coloration. General color rather uniformly light to medium brown with remnants of pale green; might have been green when alive (Fig. 1L). Head and pronotum stained brown; antennal scrobae and bases of antennae of general color, not darkened as in most other species. Face and clypeus light green. Abdomen dirty brown with rather narrow black lateral bands. Pleurae, thoracic and abdominal sternites chestnut brown. Female subgenital plate ventral surface shining black; ovipositor chestnut brown, at very base and a stroke at base of ventral valves black. Tegmen orange yellow with few black dots. Legs light to medium brown with indistinct greenish sheen; spines with black tips; fore and mid femora with indistinct transverse striation; hind femora with indistinct fish-bone pattern in about basal half. Measurements (1 female).—Body: 47; pronotum: 12; tegmen: 4; hind femur: 29; anterior femur: 15; antenna: 80; ovipositor: 24 mm. Etymology. Named after the type locality, noun in apposition.
