KEY TO THE SLATEROCORIS GROUP OF GENERA

1. Posterolateral margin of eye and posterior margin of head alined on same plane.... 2

– Posterolateral margin of eye curved anterior to posterior margin of head............................. Ilnacorella Knight, 1925

2. Apex of left paramere broad, deeply dissected, with medial and lateral lobes of variable width........................... 3

– Apex of left paramere attenuate with narrow distal region, and undivided, rounded apical knob........................... 6

3. Clavus and corium with distinct shagreened surface; sculpturation composed of minute, dense, shallow punctures without reticulation............................ 4

– Clavus and corium with sculpturation composed of large, moderately dense, deep punctures or with small to moderately large, moderately dense, moderately deep punctures covering a generally undulating or reticulate surface.......................... 5

4. Pronotum subrectangular with shagreened surface; both sexes elongate, costal margins parallel sided, hemelytron not declivous at cuneal fracture...... Ficinus Distant, 1893

– Pronotum subtriangular with shining, smooth to faintly rugulose surface; sexes dimorphic, costal margins of male variably rounded, costal margin female always more rounded than in male; hemelytron declivous at cuneal fracture......... Jornandes Distant, 1894

5. Head either entirely black or orange, sometimes black with vertex broadly orange; dorsal vestiture composed of very dense, long, recurved silvery setae; body large, sometimes total length of macropterous specimens reaching 7.50 mm, always greater than 4.50 mm, if female brachypterous then ranging from 3.55 to 4.00 mm and scutellum usually pale yellowish orange.... Lopidella Knight, 1925

– Head usually black with vertex narrowly pale yellow, sometimes head black with pale yellow near eyes or if head completely black then body small, dorsum shining, and vestiture sparse and black; dorsal vestiture variable, either composed of sparse, short, brown to black or moderately dense, longer recurved, silvery simple setae; body small usually shorter than 4.50 mm; females never brachypterous or with pale scutellum............... Scalponotatus Kelton, 1969

6. Body large and broad (length and width usually greater than 6.00 and 2.75 in male and 6.50 and 3.50 in female); head shining orange, labium short, reaching just beyond forecoxa, frons strongly protruding; dorsum glabrous; endosomal spicule with long, thin, smooth spine at base and middle, both spines perpendicular to body of spicule; right paramere without ventrally directed spines distal to strongly serrate basal lobe...... Jornandinus Carvalho and Schaffner, 1973

– Body almost always shorter; if length of male 7.00 then width is less than 2.25; head usually entirely black, sometimes pale near medial margin of eye; if head orange then dorsum pubescent; labium always surpassing middle coxa; dorsum with variable vestiture; endosomal spicule either clearly bifurcate with dorsal and ventral lobes, or with small spine parallel to body of spicule; right paramere with ventrally directed spines, or basal lobe without spines..................... 7

7. Vertex anterior to transverse basal carina steeply angled; hemelytron rugose or reticulate surface with moderately large discrete or obscure punctures; endosomal spicule clearly bifurcate with dorsal and ventral lobes, apex of dorsal lobe extending beyond apex of secondary gonopore; right paramere with ventrally directed spines............................ Slaterocoris Wagner, 1956

– Vertex anterior to transverse basal carina gradually angled; hemelytron with variable sculpturation—either discrete, minute punctures only, or with discrete, minute punctures underlying shingle-shaped plates, or with shingle-shaped plates only; endosomal spicule with small spine parallel to body of spicule, apex of spine not extending beyond apex of secondary gonopore; right paramere with one large dorsally directed lobe or without lobes..........................................
