Key to the Oriental species of Brachycerocoris

1 Anterior half of pronotum with well developed, prominent, pointed central tubercle, distinctly longer than width at base (in lateral view) ( Fig. 1b ), with apex truncate......................................... Brachycerocoris camelus Costa

- Anterior half of pronotum with central tubercle usually distinctly shorter than width at base ( Fig. 2c ; Fig. 3b ) and apex of central tubercle distinctly rounded, if as long as width at base, the central tubercle at basal half of scutellum (scutellar tubercle) much elongate (> 2 mm in height) ( Fig. 4b )..................................................................... 2

2 Central tubercle at basal half of scutellum (scutellar tubercle) much elongate, usually more than 2 mm in height ( Fig. 4b )......................................................... Brachycerocoris davidii Roca-Cusachs & Salini sp. nov.

- Central tubercle at basal half of scutellum (scutellar tubercle) short with 1 mm in height ( Fig. 2c ; Fig. 3b ).............. 3

3 The central margin connecting base of central tubercle on basal half of scutellum with posteromedial scutellar tubercle, straight (in lateral view) ( Fig. 2c ); Paramere distinctly P-shaped, apex of crown broader than long, crown massive ( Fig. 9 d, e ); stem medially concave on outer margin and not of uniform width throughout................................................................................................... Brachycerocoris petrii Salini & Roca-Cusachs sp. nov.

- The central margin connecting base of central tubercle on basal half of scutellum with posteromedial scutellar tubercle, Cshaped (in lateral view) ( Fig. 3b ); Paramere distinctly L-shaped, apex of crown semiovate, crown not massive ( Fig. 13 a, b ); stem of uniform width throughout..................................... Brachycerocoris dromedarius (Vollenhoven)
