 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. Body clothed with pale or dark simple adpressed setae, those setae pale on dorsum and dark on appendages; setae on hind tibia extremely long and dense; flattened setae on hemelytron absent. STRUCTURE. Head. Distance between eye and pronotum shorter than eye diameter (as in Fig. 10F); occipital region not delimited with depression; longitudinal depression on vertex indistinct or very short; eyes stylate, directed outwards (as in Fig. 10H), c. 0.25× as long as head width; distance between antennal fossa c. 3× as long as antennal fossa diameter; frons distinctly swollen, with paired tubercles, without longitudinal depression or ridges; anterior view of head c. 1.5× as wide as high; eye height c. 0.8× as distance from eye to apex of clypeus; antennal fossa oval, c. 0.3× as long as eye height, not raised (as in fig. 3B in Namyatova et al., in press), its inferior margin placed near inferior margin of eye and base of clypeus; base of clypeus distinctly delimited basally; in lateral view head flat; gula shorter than buccula length, straight. Labium. Reaching posterior margin of metasternum; LSI c. 2–3× as long as wide; LSII c. 4× as long as wide, slightly longer than LSI; LSIII c. 4× subequal to LSII; LSIV c. 6× as long as wide, c. 1.5× as long as LSIII. Antenna. Reaching base of cuneus; ASI c. 1.5–2× as long as wide, subequal to quarter of head width, swollen basally (as in fig. 8E in Namyatova et al., in press); ASII c. 5× as long as ASII, c. 0.8× as long as head and pronotum combined, slightly incrassate apically, without tumescences; Thorax. Collar not delimited, flat; calli separated, flat; depression delimiting calli posteriorly absent (as in fig. 4C in Namyatova et al., in press); humeral angles of pronotum dilated; posterior margin of pronotum distinctly concave, forming right angles, scutellum distinctly swollen, triangular (as in Fig. 11H), not covering base of pronotum, not divided into parts (as in Fig. 12A), obtuse apically, without longitudinal depression, ridge or outgrowth; metepimeron c. 1.5× as high as long, angulate (as in Fig. 13E); metasternum with medial projection to abdominal segment II (as in fig. 17A in Namyatova et al., in press). 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).
