Material examined. Diabrotica trifurcata: Lectotype male (BMNH): 1) [Lectotype]; 2) [V. de Chiriqui, 2–3000 ft. Champion.]; 3) [Type. Sp. figured.]; 4) [Diabrotica trifurcata Jac.]; 5) [Godman-Salvin Coll., Biol. Centr.-Amer.]; 6) [Lectotype Diabrotica trifurcata Jac. RFS]. Paralectotype male and female (BMNH): 1) [Paralectotype]; 2) [Chontales, Nicaragua. Janson.]; 3) [Godman-Salvin Coll., Biol. Centr.-Amer.]; 4) [paraLectotype Diabrotica trifurcata Jac. RFS]. Paralectotype female (BMNH): 1) [Paralectotype]; 2) [Chontales, Nicaragua. T. Belt.]; 3) [Godman-Salvin Coll., Biol. Centr.-Amer.]; 4) [paraLectotype Diabrotica trifurcata Jac. RFS]. Paralectotype female (BMNH): 1) [Paralectotype]; 2) [Chontales, Janson]; 3) [trifurcata Jac.]; 4) [Baly coll.]; 5) [paraLectotype Diabrotica trifurcata Jac. RFS]. Paralectotype male (BMNH): 1) [Paralectotype]; 2) [Irazu, 6–7000 ft. H.Rogers.]; 3) [Godman-Salvin Coll., Biol. Centr.-Amer.]; 4) [paraLectotype Diabrotica trifurcata Jac. RFS]. Paralectotype male (MCZ): 1) [V. de Chiriqui, Champion]; 2) [Diabrotica trifurcata Jac.]; 3) [1st Jacoby Coll.]; 4) [Type 17686]; 5) [LectoParatype Diabrotica trifurcata Jac.]. Paralectotype male (MCZ): 1) [Chontales, Nicaragua. Janson.]; 2) [1st Jacoby Coll.]; 3) [LectoParatype Diabrotica trifurcata Jac.]. Paralectotype female (MCZ): 1) [Chontales, Nicaragua. T. Belt.]; 2) [1st Jacoby Coll.]; 3) [LectoParatype Diabrotica trifurcata Jac.].
Diabrotica linensis: Lectotype male (BMNH): 1) [V. de Chiriqui, 4000–6000 ft. Champion.]; 2) [Lectotype Diabrotica linensis Baly (= elongatula Jac.)]. Male (USNM): [Costa Rica: Las Cruces, Nr. San Vito 19–20.III.65. SS&WDDuckworth].
We studied the internal sacs of the aedeagi of the lectotypes of D. linensis (Figs 55–57) and D. trifurcata (Figs 50–52) and found no significant differences between them. The elytral color patterns of D. linensis (Figs 53, 54) and D. trifurcata (Figs 48, 49) are different, but that alone is not sufficient to justify the recognition of species status for D. linensis. Therefore, we treat D. linensis as a synonym of D. trifurcata. In the type series of D. trifurcata Jacoby at the BMNH, one paralectotype is not a Diabrotica: 1) [Paralectotype]; 2) [Chontales, Nicaragua. Janson.]; 3) [Godman-Salvin Coll., Biol. Centr.-Amer.]; 4) [paraLectotype Diabrotica trifurcata Jac. RFS]. We do not know what genus this specimen belongs to.
