Diagnosis: Among other genera of the Odoniella - complex, Odoniella itself is recognized by ASII only slightly incrassate apically; ASIV distinctly clavate; yellow to reddish coloration ( Fig. 8); humeral angles of pronotum distinctly flattened, pronotum and scutellum without tumescences ( Fig. 10G); scutellum distinctly swollen ( Fig. 11E, fig. 12E in Namyatova et al., in press), not divided into lower and upper parts (as in Fig. 12A); without tubercles or bifurcated outgrowth on frons; eye directed distinctly outwards and forwards ( Fig. 10G); and body clothed with simple setae only.

Redescription: Male: Body length 7–10 mm. COLORA- TION ( Fig. 8).

TEXTURE. Body without tubercles and wrinkles; flattened areas on vertex indistinct; pronotum and scutellum covered with distinct dense punctures; pair of punctures between calli, pair of punctures between mesoscutum and scutellum, punctures on clavus and on R + M absent (fig. 12E in Namyatova et al., in press); striations on lateral margins of scutellum present; semicircular depression between scutellum and mesoscutum absent. VESTITURE. Body clothed with simple setae; adpressed pale setae on dorsum, thoracic pleura and abdomen present; setae on head, pronotum, scutellum and pleura often very rare; setae on antennae mostly dark and adpressed, often pale on ASI- II; setae on legs mostly pale and adpressed, not very dense, setae on tibia spine like and suberect; black spinules on femora and tibiae irregularly dis- tributed (as in fig. 18F in Namyatova et al., in press). STRUCTURE. Head. Distance between eye and pronotum as long as or slightly longer than eye diameter ( Fig. 10G); occipital region not delimited with depression; longitudinal depression on vertex absent or very short and shallow; eyes stylate, directed outwards and forwards ( Fig. 10G), c. 0.17–0.22× as long as head width; distance between antennal fossa as long as or slightly longer than antennal fossa diameter; frons distinctly swollen, without ridges, outgrowth(s) or longitudinal depression ( Fig. 10G); anterior view of head c. 1.5– 1.8× as wide as high; eye as long as or slightly longer than distance between eye and apex of clypeus; antennal fossa oval, diameter subequal to or slightly longer than half of eye height, not raised; inferior margin of fossa placed slightly above inferior margin of eye; base of clypeus placed near or slightly above inferior margin of eye, delimited with depression (fig. 3B in Namyatova et al., in press); head almost flat in lateral view; gula shorter than buccula length, straight. Labium. Slightly surpassing middle of mesosternum or almost reaching posterior margin of mesosternum; LSI c. 2.5–3× as long as wide, LSII c. 2–2.5× as long as wide, as long as or slightly shorter than LSI; LSIII c. 2.5–3× as long as wide, as long as or slightly longer than LSIII; LSIV c. 4× as long as wide, c. 1.5–2× as long as LSIII. Antenna. Reaching base of cuneus; ASI c. 1.5–2× as long as wide, subequal to one third of head width, swollen basally (as in fig. 8E in Namyatova et al., in press); ASII c. 5× as long as ASI, c. 0.8–0.9× as long as head and pronotum combined, slightly incrassate towards apex, without swellings; ASIII c. 0.7–0.9× as long as ASII, widened towards apex; ASIV c. 0.7× as long as ASIII, clavate. Thorax.

Hemelytron. Costal margin of hemelytron slightly rounded; claval commissure c. 0.3–0.7× as long as scutellum, straight; R + M distinct only anteriorly and medially, not reaching posterior margin of corium (fig. 12E in Namyatova et al., in press); medial fracture strongly inclined towards midline; cuneus c. 1.7–2.4× as long as wide, c. 0.7– 0.9× as long as pronotum, medial margin slightly concave (fig. 13B in Namyatova et al., in press); membrane cell slightly or distinctly surpassing apex of cuneus, forming right angle, as long as or slightly longer than pronotum (fig. 13B in Namyatova et al., in press); auxiliary vein absent; distance from cell to apex of membrane c. 1.7–1.9× as long as cell length. Legs. Forecoxae contiguous (fig. 17A in Namyatova et al., in press); femora almost not swollen apically, straight; foretibia shorter than head and pronotum combined; tibia without swellings; segment I of hind tibia of as long as segment II and distinctly shorter than segment III; apical half ore third part curved or claw broadly rounded; basal tooth on claw very short, triangular, or elongate, straight or slightly concave (as in Fig. 13J). Genitalia ( Fig. 16M–S). Genital capsule as long as or slightly shorter than wide, without outgrowth(s), ventral wall not shortened anteriorly; left paramere r-shaped, c. 1.5–2× times as long as right paramere; phallobase sclerite of primary gonopore subtriangular or suboval, without outgrowth(s); ductus seminis not sclerotized basally or apically, shorter than phallotheca, with coils forming wide tube, attached to phallobase medially; sclerotized part of phallotheca broad, occupying almost entire dorsal portion, rounded apically, without ridge or outgrowths(s); endosoma with single or a number of serrate spicules.

Female: Body length 9–12.5 mm. Coloration, surface, vestiture and structure as in male ( Fig. 8). Genitalia ( Fig. 19P, Q). DLP with sclerotized ring, with pair of symmetrical striated areas; lateral oviducts attached at middle of those striated areas, widely separated, placed near lateral margin and at a halfway of DLP; spermathecal gland placed posteriorly, slightly shifted right, posterior wall with small tubercles, without outgrowths and sclerotization; base of second valvula concave; ventral wall membranous.

Distribution: Distributed in tropical Africa ( Fig. 24).

Host plants: Odoniella reuteri and O. rubra have been recorded from cocoa ( Leston, 1970; Entwistle, 1977). Odoniella apicalis and O. rubra are also known from Piper spp. ( Piperaceae ), Odoniella camerunesis was recorded from Culcasia parviflora ( Araceae ), and Odoniella similis is known from Smilax sp. ( Smilaceae ) ( Odhiambo, 1962; Hill, 1983).
