 Bryocoropsis Schumacher, 1917: 453 (gen. nov.; type species Bryocoropsis laticollis by monotypy); Bergroth, 1922: 53 (cat.); China, 1944: 179 (key to gen.); Carvalho, 1952: 60 (cat.); Carvalho, 1955: 41 (key to gen.); Carvalho, 1957: 143 (cat.); Odhiambo, 1962: 298 (disc.); Lavabre, 1977a: 51 (key to gen.); Schuh, 1995: 526 (cat.); Schuh, 2002 –2013 (cat.); Namyatova et al., in press (phylogeny).   
 Diagnosis: Bryocoropsis belongs to the Odoniella - complex and can be distinguished from other genera in this group by the following characters: coloration mostly brown, body oval (Fig. 8), ASII distinctly incrassate towards apex, with tip not swollen or only slightly swollen; ASIII–IV distinctly clavate (as in fig. 9F in Namyatova et al., in press); eyes stalked, distinctly directed laterally (as in Fig. 10H); pronotum and scutellum often with shallow tumescences (Fig. 11D); setae on pronotum very rare; long and flattened setae on hemelytron; scutellum distinctly swollen, not exceeding pronotum height, nor divided into lower and upper regions (as in Fig. 12A); spermathecal gland attached to right of midline (Fig. 18G, I).

VESTITURE. Body clothed with setae shorter than width of hind tibia; head, pronotum, scutellum, thoracic pleura and abdomen clothed with simple short suberect setae, those setae on dorsal side of head, pronotum, scutellum and thoracic pleura very rare; hemelytron clothed with dark and pale flattened setae, sometimes only slightly flattened; ASI with rare pale or darkened adpressed setae, sometimes flattened; ASII–IV and legs with more or less dense semiadpressed spine-like setae, setae on ASII– IV dark, setae on legs usually pale, sometimes dark; black spinules on femora and tibiae irregularly distributed (as in fig. 18F in Namyatova et al., in press). STRUCTURE. Head. Distance between eye and pronotum shorter than eye diameter (as in Fig. 10F, H); occipital region not delimited with depression; longitudinal depression on vertex absent or very short and shallow; eyes stylate, directed outwards (as in Fig. 10F, H), c. 0.15–0.2× as wide as head; distance between antennal fossa twice as long as antennal fossa width; frons distinctly swollen with paired outgrowths (as in fig. 4C in Namyatova et al., in press), without ridges or longitudinal depression; anterior view of head c. 1.7– 1.9× as wide as high; eye as long as or slightly longer than distance between eye and apex of clypeus; antennal fossa oval, diameter c. 0.5–0.7× as long as eye height, not raised (as in fig. 3B Namyatova et al., in press); inferior margin of fossa placed near inferior margin of eye; base of clypeus placed at halfway of antennal fossa height; delimited with depression; head flat form lateral view; gula as long as or shorter than buccula length, slightly convex. Labium. Almost reaching or slightly surpassing anterior margin of metasternum; LSI c. 2–2.5× long as wide; LSII c. 3–4× as long as wide, subequal or slightly longer than LSI; LSIII c. 3–4× as long as wide, subequal to LSII; LSIV 5–6× as long as wide, c. 1.5× as long as LSIII. Antenna. Reaching apex of clavus; ASI c. 1.5× as long as wide, c. 0.25–0.35× as long as head width, widened basally (as in Fig. 10F–H); ASII c. 5–6× as long as ASI, c. 0.7– 0.9× as long as head and pronotum combined, widened towards apex or swollen apically, without any swellings basally and medially (as in fig. 8E in Namyatova et al., in press); ASIII c. 0.6–0.7× as long as ASII, widened towards apex; ASIV c. 0.6–0.8× as long as ASIII, clavate (as in fig. 8F in Namyatova et al., in press). Thorax. Collar fused with callosite region or rarely delimited medially, flat; calli separated, flat; depression delimiting calli posteriorly absent (as in fig. 4C in Namyatova et al., in press); humeral angles of pronotum slightly or distinctly dilated, not serrate; posterior margin of pronotum distinctly concave, forming right angles (as in Fig. 10G, fig. 4C in Namyatova et al., in press); scutellum swollen, not covering base of pronotum, trapeziform, not divided into parts, obtuse apically (Figs 11D, 12A) with or without longitudinal depression medially, without outgrowth or ridge; metepimeron enlarged, c. 1.5–2× as high as long, angulate, subtriangular (as in Fig. 13E); metasternum with medial projection to abdominal segment II (as in Fig. 17A in Namyatova et al., in press). Hemelytron.

 Females: Length c. 7–8 mm. Coloration, surface, vestiture and structure as in male, but females slightly larger than males (Fig. 8). Genitalia (Fig. 18G–J). DLP with a single sclerotized ring anteriorly, more than 3× as long as wide; two large areas of striations present, equal in diameter or right one distinctly larger than left; lateral oviducts attached at middle of those striated areas, widely separated, placed near lateral margin and at midpoint of DLP; spermathecal gland placed posteriorly, orientated slightly to right-hand side; posterior wall with small tubercles, without outgrowths and sclerotization; base of second valvula straight or slightly curved; ventral wall membranous.   
 Distribution: Known from tropical Africa (Fig. 23).   
 Host plants: Species of this genus are known to feed on cocoa (Leston, 1970; Entwistle, 1977), as well as from some species of the family Annonaceae (Piart, 1977).
