Diagnosis: Platyngomiris belongs to the Odoniella - complex (see discussion for the tribe) and is recognized by the following characters: ASIII distinctly incrassate apically, ASIV clavate (as in fig. 8E in Namyatova et al., in press); frons with paired tubercles; scutellum distinctly swollen (as in Fig. 11H ), exceeding height of pronotum, subtriangular, not subdivided into lower and upper parts (as in Fig. 12A ), hemelytron clothed simple setae only, hind tibiae with tumescences and clothed with long and extremely dense setae.

Redescription: Female: Body length 9.5 mm. COLORA- TION ( Fig. 8 ). Coloration mainly brown, hemelytron mostly pale, almost yellow, but cuneus brown. TEXTURE. Tubercles on vertex and flattened areas indistinct; wrinkles on head absent; ASII without tubercles; pronotum and scutellum punctate; tubercles on collar very shallow; shallow tumescences on pronotum and scutellum present; row of punctures on clavus and on R + M and punctures on depression delimiting calli posteriorly absent; striations on lateral margins of scutellum indistinct or present only anteriorly; hind tibia with tumescences; semicircular depression between scutellum and mesoscutum absent; hemelytron smooth, without tubercles. VESTITURE.

Hemelytron. Tapering posteriorly; costal margin straight (as in fig. 12E in Namyatova et al., in press); claval commissure c. 0.2× as long as scutellum, straight; R + M almost reaching posterior margin of corium; medial fracture strongly inclined towards midline (as in fig. 12E in Namyatova et al., in press); corium without swelling posteriorly; cuneus c. 1.7× as long as wide, c. 0.6× as long as pronotum, medial margin slightly concave; membrane cell distinctly surpassing apex of cuneus, forming acute angle, c. 0.9× as long as pronotum; auxiliary vein absent; distance from cell to apex of membrane c. 0.79× as long as cell. Legs. Forecoxae contiguous (as in fig. 17A in Namyatova et al., in press); femora almost not swollen apically, straight, hind tibia often slightly curved; foretibia shorter than head and pronotum combined. Genitalia ( Fig. 21E, F ). DLP with a single sclerotized ring anteriorly, c. 1.5× as long as wide; with paired areas of striations, placed at base of lateral oviducts; lateral oviducts in posterior half of DLP; spermathecal gland placed medially at posterior margin; posterior wall with small tubercles, without outgrowths with paired sclerotization posteriorly; base of second valvula concave; ventral wall membranous.

Distribution: Known from Borneo only ( Fig. 23 ).

Host plants: The genus is known as a pest of cocoa ( Ghauri, 1963; Leston, 1970; Azhar, 1989; Keane & Putter, 1992; Schaefer & Panizzi, 2000).
