Agalliopsis fasciata Osborn 1934: 164 View in CoL , fig. 1. HOLOTYPE ♀, SAMOA IS. [BMNH, examined].

Color. Ochraceous with dark brown patches. Median half of vertex chocolate brown (result of fusion of two round lateral spots, median stripe, their shape more clearly visible in facial view).

Male genitalia. Caudal lobe of pygofer rounded and produced into darkly pigmented mesal lobe. Styles stout, long, inner arm slender, longer than outer arm, dorsal angle prolonged. Connective as long as wide, anteriorly produced in middle, caudal margin medially excavated. Aedeagus in lateral view V-shaped, dorsal apodeme well developed, closely oppressed to shaft, shaft slightly curved at apical 0.33 bearing subapical tooth on right lateral margin, apically terminated by two short processes, gonopore subapical.

Female genitalia. Hind margin of female seventh sternite straight.

Material examined. SAMOA: HOLOTYPE ♀, “Type” “Samoan Is.” “Malololeleci” “Upolu 2000ft, 14– 30.vi.24, P.A. Burton and G.H. Hopkins [red label]” “ Holotype Agalliopsis fasciatus Osborn ” ( BMNH) . Additional material: 1 ♂, Upolu: Afiamalu, 3.vi.1940, O.H. Swezey, Agalliopsis fasciatus Osborn, O.H. Swezey det. ( BPBM) .

Remarks. I. fasciata resembles Agallia hilaris Horváth from Canary Islands ( Horváth 1909, Lindberg 1954) but differs in the coloration, position of the ocelli and the structure of the male genitalia.
