Biclonuncaria recurvana, new species (Lepidoptera: Tortricidae: Polyorthini), is described and illustrated from Area de Conservación Guanacaste in northwestern Costa Rica. It is most similar to B. conica Razowski, 1993, from Mexico, but the two are easily distinguished by features of the male genitalia. Biclonuncaria recurvana has been reared (n = 12 specimens) from field-collected larvae feeding on the leaves of Dalbergia glomerata Hemsley (Fabaceae), consistent with the previously reported host plant for B. dalbergiae Razowski and Becker, 1993, which has been reared from Dalbergia in Brazil.

Although well studied in the Afrotropical Region, the genus Cosmorrhyncha Meyrick, 1913 (Lepidoptera: Tortricidae: Olethreutinae), has received little attention in the New World, where it apparently is restricted to the Neotropics from Guatemala south to Paraguay. Seven species are recognized, five of which are described as new: C. tonsana (Walker, 1863) (Type locality: Brazil); C. ocelliferana (Walker, 1863) (TL: Brazil); C. landryi Brown and Razowski, sp. n. (TL: French Guiana); C. parintina Brown and Razowski, sp. n. (TL: Brazil); C. macrospina Brown and Razowski, sp. n. (TL: Brazil); C. albistrigulana Brown and Razowski, sp. n. (TL: Costa Rica); and C. osana Brown and Razowski, sp. n. (TL: Costa Rica). Our circumscription of C. ocelliferana is rather broad and most likely encompasses a species complex rather than a single entity. Larvae of C. tonsana have been reared from Picramnia latifolia Tul. (Picramniaceae), Dialium guianense (Aubl.) Sandwith (Fabaceae), and Machaerium seemannii Benth. ex Seem. (Fabaceae) in Costa Rica; and those of C. albistrigulana from Dialium guianense (Fabaceae).
Saphenista bartellae Brown, new species (TL: Colorado), and S. powelli Brown, new species (TL: California) (Lepidoptera: Tortricidae), are described and illustrated. Two other western North American species, S. latipunctana (Walsingham, 1879), new combination, and S. dilutana (Walsingham, 1879), new combination, are transferred to Saphenista based on morphology of the genitalia.
We recognize and review 40 species of Chlamydastis Meyrick, 1916 (Lepidoptera: Depressariidae) from Costa Rica, including four previously described (i.e., C. vividella (Busck, 1914), revived status; C. phytoptera (Busck, 1914); C. orion Busck, 1920; and C. ungulifera (Meyrick, 1929)) and 36 new species: C. abelulatei Phillips and Brown, new species; C. carolinagodoyae Phillips and Brown, new species; C. angelsolisi Phillips and Brown, new species; C. lindapitkinae Phillips and Brown, new species; C. iangauldi Phillips and Brown, new species; C. anniapicadoae Phillips and Brown, new species; C. antonioazofeifai Phillips and Brown, new species; C. mignondavisae Phillips and Brown, new species; C. marianofigueresi Phillips and Brown, new species; C. colleenhitchcockae Phillips and Brown, new species; C. bernardoespinozai Phillips and Brown, new species; C. bobandersoni Phillips and Brown, new species; C. carlosviquezi Phillips and Brown, new species; C. christerhanssoni Phillips and Brown, new species; C. christhompsoni Phillips and Brown, new species; C. paulhansoni Phillips and Brown, new species; C. elenaulateae Phillips and Brown, new species; C. gladysrojasae Phillips and Brown, new species; C. powelli Phillips and Brown, new species; C. gracewoodae Phillips and Brown, new species; C. juanmatai Phillips and Brown, new species; C. isidrochaconi Phillips and Brown, new species; C. jimlewisi Phillips and Brown, new species; C. jimmilleri Phillips and Brown, new species; C. montywoodi Phillips and Brown, new species; C. johnnoyesi Phillips and Brown, new species; C. luisdiegogomezi Phillips and Brown, new species; C. paulthiaucourti Phillips and Brown, new species; C. dondavisi Phillips and Brown, new species; C. irenecanasae Phillips and Brown, new species; C. manuelzumbadoi Phillips and Brown, new species; C. noramartinae Phillips and Brown, new species; C. vitorbeckeri Phillips and Brown, new species; C. ronaldzunigai Phillips and Brown, new species; C. munifigueresae Phillips and Brown, new species; and C. willsflowersi Phillips and Brown, new species.COI nucleotide sequences (“DNA barcodes”) were obtained for 33 of the species, which helped associate males with females for sexually dimorphic species and revealed a few cryptic, presumably evolutionary siblings. We illustrate adults of all species, along with their male and female genitalia, where available.Nineteen species were reared from caterpillars, and their foodplants are listed. In Costa Rica, 15 species of Chlamydastis are recorded exclusively from Sapotaceae; one species each exclusively from Clethraceae, Vochysiaceae, Combretaceae, and Melastomataceae. Larvae are illustrated for 10 of the 36 new species, and superficial larval descriptions are provided based on photographs and notes. Of the 40 species of Chlamydastis reported from Costa Rica, 32 have been light-collected or reared from Área de Conservación Guanacaste.
A biological inventory focused on plant-caterpillar-parasitoid associations at Yanayacu Biological Station, Ecuador, yielded 81 adult specimens of Tortricidae (Lepidoptera: Tortricoidea) representing 42 species in 13 genera. Based on this material, new host records are presented for species in the following genera: Lypothora Razowski, 1981; Inape Razowski, 1988; Orthocomotis Dognin, 1905; Paraptila Meyrick, 1912; Runtunia Razowski and Wojtusiak, 2008; Transtillaspis Razowski, 1987; Xoser Razowski and Pelz, 2003; Argyrotaenia Stephens, 1852; Anacrusis Zeller, 1877; Sisurcana Powell, 1986; Amorbia Clemens, 1860; Paramorbia Powell and Lambert, 1986; and Episimus Walsingham, 1892. Tortricids were reared from 46 plant species representing 24 plant families, with Piperaceae, Melastomataceae, and Asteraceae supporting the most tortricid herbivores (six species each).
Eight new species of Eucosmocydia Diakonoff are described and illustrated from the Afrotropical region: E. pappeana Brown and Razowski, new species (TL: Kenya); E. deinbolliana Brown and Razowski, new species (TL: Kenya); E. ugandensis Aarvik, new species (TL: Uganda); E. lecaniodiscana Brown and Razowski, new species (TL: Kenya); E. nigeriana Brown and Razowski, new species (TL: Nigeria); E. pancoviana Brown and Razowski, new species (TL: Kenya); E. kirimiriana Brown and Razowski, new species (TL: Kenya); and E. macabensis Brown and Razowski, new species (TL: Mauritius). Three additional species are transferred to the genus: E. hymenosa (Razowski, 2013), new combination (TL: Nigeria); E. chlorobathra (Meyrick, 1911), new combination (TL: Seychelles); and E. trigonoptila (Meyrick, 1921), new combination (TL: Mozambique). We also transfer to the genus E. catamochla (Meyrick, 1932), new combination (TL: Indonesia), the first species recorded outside the Afrotropical region. We recognize two species groups in Eucosmocydia, and this contribution focuses on the oedipus Diakonoff, 1988 group (n = 13 species), the males of which are characterized by a unique flattened lobe from the base of the hindwing. Six species from Kenya were reared exclusively from native fruit of Sapindaceae; E. mixographa (Meyrick) was formerly reported from Fabaceae and Euphorbiaceae.

A database of larval host plants for the tortricid tribe Grapholitini (Lepidoptera: Tortricidae: Olethreutinae) is presented, and larval hosts are summarized for each genus. Food plants have been reported for over 400 of the approximately 1,644 described species of Grapholitini. Of the 81 genera currently assigned to the tribe, at least one larval host has been reported for 51. Ninety-seven different plant families have been reported at least once for a species of Grapholitini, with the greatest number of grapholitines recorded from Fabaceae (168 species), followed by Fagaceae (43 species), Pinaceae (43), Sapindaceae (36), Rosaceae (30), Asteraceae (30), Euphorbiaceae (15), Rutaceae (12), Annonaceae (12), Salicaceae (11), and Cupressaceae (11). Thirty-two genera appear to be restricted, or nearly so, to specific host families, but many of these are either monotypic or are represented by exceedingly few records. Extraordinarily, entomophagy is well documented in three genera: Andrioplecta, Coccothera, and Parapammene. Two new combinations are provisionally proposed based on hosts and male genitalia: Andrioplecta magnetica (Meyrick, 1928), new combination, and A. theristis (Meyrick, 1912), new combination, both of which are currently assigned to “Grapholitini unplaced species.”
