Zusammenfassung:Leucoloma crosbyi, a new species from northern Madagascar, is described, resulting from a revision of the pantropical genus. Diagnostic characters include: robust habit; narrow, opaque, juxtacostal bands tapering to basal region; costal-laminal transition zone with 2-9 multi- to bistratose rows; interior cells forming broad scarious region; narrow hyaline margin; and longitudinally thick-walled alar cells. It is most closely related to L. grandidieri Ren. & Card, and has been confused with L. talazaccii Ren. & Card.
