4.
Bagous quadrimaculatus
group
Diagnosis.
Pronotum with more or less distinctly carinate basal margin across middle one-fourth to one-half. Basal margin of elytra swollen, slightly to markedly costate from scutellum to, or almost to, humerus. Sclerotization of ventral surface of penis body broadly membranous. Endophallus lacking sclerites.
Remarks.
This monospecific group includes a species from the Indian subcontinent well characterized by a series of homoplastic characters. Habitus and shape of the male genitalia seem more similar to those of the species of the
B. compertus
group.
Species included.
