Introduction

PogrimaSchaus, 1940, was established in the Galleriinae, as a monotypic genus, and was assigned to the Tirathabini by Whalley (1964) and maintained as such by Munroe (1995, p. 88).

Material and methods

This work is based on the vast material belonging to these and related species in the author’s collection (VOB) and in the collections of other major museums (USNM, IES), and on the pertinent literature. A synoptic collection, representing all the species, was taken to USNM and NHMUK and compared with the material deposited in these institutions. The holotypes of the new species are provisionally deposited in VOB, and will be transferred, together with the collection, to a Brazilian institution in the future. Genitalia were prepared following the methods described by Robinson (1976). Terms for morphological characters follow Hodges (1971).

Diagnosis: Small. FW length 4-8 mm (10-18 mm wingspan), grey, markings dark grey, orbicular spot black, well defined; diffuse, whitish area above cell, from base to costa before postmedial band; R3+4 (Figure 5) to costa before apex, stalked halfway between R2 and apex; M1 from upper angle of cell, close to Rs; M1+M2+CuA1 stalked, from lower angle of cell; CuA2 from near lower angle. HW with Sc+Rs+M1 from upper angle of cell, Sc+Rs stalked halfway between M1 and apex; M2 absent, M3+CuA1 stalked beyond lower angle of cell. Labial palpus short in males, 1/2 size of eye diameter; long, porrect, 3x eye diameter in females. Male genitalia with uncus short, broad, densely covered with long setae dorsally; valva spatulate, 3-4x as long as wide; vinculum round; phallus straight, vesica with no spines. Female genitalia as described for P. palmasalis (below).

Distribution: Antillean.

Remarks: Presumably related to Tineopaschia minuta Hampson, 1916, a smaller species with similar pattern.

Acknowledgments

Diego R. Dolibaina, Serra Bonita Reserve, prepared the illustrations. Dr Scott E. Miller (USNM) and Dr Bernard Landry (Muséum d’Histoire Naturelle, Geneva, Switzerland), reviewed the manuscript and suggested some changes that improved the article. Collections from Guana Island were supported by The Conservation Agency, through a grant from the Falconwood Corporation. James D. Lazell and Dr S. E. Miller (USNM) provided arrangements to work on the island. Collecting in Puerto Rico was made possible with the support of G. Maldonado Capriles, and in St. Thomas with support of W. P. MacLean. Collecting in Cuba was partly supported by the Academia de Ciencias, with the collaboration in the field of Jorge de la Cruz, Rafael Alayo and Eduviges Valdés (IES). Dr Antonio Vives (Madrid, Spain), the editor of SHILAP Revta. lepid., did a careful and competent job, as usually. To all of them my most sincere gratitude.
