cyaneomaculata Jacoby 1887, incertae sedis.

(Figs 68–71)

cyaneomaculata Jacoby 1887: 523 [Type locality: Volcan de Irazu, Costa Rica; type depository: BMNH, lectotype, female, designated by Smith and Lawrence (1967: 54) examined] as Diabrotica .

Material examined: Lectotype female (BMNH): 1) [Type]; 2) [Irazu, 6–7000 ft. H. Rogers]; 3) Type. Sp. figured.]; 4) [Godman-Salvin Coll. Biol. Centr.-Amer.]; 5) [ Diabrotica cyaneomaculata Jac.]; 6) [Lectotype Diabrotica cyaneomaculata Jac. RFS]. Paralectotype male (BMNH): 1) [Paralectotype]; 2) [Cache. Costa Rica. H. Rogers]; 3) [Godman-Salvin Coll. Biol. Centr.-Amer.]; 4) [Lectoparatype Diabrotica cyaneomaculata Jac. RFS]. Paralectotype female (MCZ): 1) [Costa Rica. V. Patten.]; 2) [ Diabrotica cyaneo-maculata Jac.]; 3) [1st Jacoby Coll.]; 4) [Type 17689]; 5) [Lectoparatype Diabrotica cyaneomaculata Jac.]. Two males and two females (MCZ): [C. Rica]. One male (MCZ): [Costa Rica]. One female (MCZ): [ Diabrotica cyaneomaculata]. One female (MCZ): 1) [Costa Ri]; 2) [1st Jacoby Coll.].

After studying the type material of D. cyaneomaculata, it became clear that this species possesses a set of characters that do not make it congeneric with Diabrotica species: aedeagus without orificial plate; internal sac very weakly sclerotized, lacking sclerotized hooks, plates and other armature (Figs 70–71); eyes relatively small, genal space as wide as one-fourth to one-half of maximum diameter of eye. Extensive generic level studies of the New World Galerucinae are needed to find the proper generic placement for this species.
