(Figs. 1, 204–206, 286, 355, Map 37) Diagnosis.— Glyphidocera vappae is most similar to G. f o r m a e but differs from the latter by having slightly smaller and more narrowly separate costal furcae of the valva, a shorter apical curnutus of the aedeagal vesica, and absence of cornuti within vesica of aedeagus.

Description.— Head: Vertex and frontoclypeus brownish yellow; outer surface of labial palpus dark brown intermixed with brownish­yellow scales to apical margin of segment II, segment III dark brown intermixed with few brownish­yellow scales; inner surface of segment I–II pale brownish­yellow scales intermixed with few dark­brown scales, segment III dark brown intermixed with few pale brownish­yellow scales; scape of antenna brownish yellow or brownish yellow intermixed with few dark­brown scales, flagellum with alternating bands of brownish­yellow and brown scales; male 4 th flagellomere dorsally protuberant and curved, forming a deep concavity opposite slightly excavated flagellomeres 5–6; concavity nearly closed by a few setiform scales on apex of protuberance of 4 th flagellomere; proboscis brownish yellow.

Thorax: Tegula and mesonotum brownish yellow or brownish yellow intermixed with few dark­brown scales. Legs brownish yellow intermixed with brown scales, apical margins of all segments and tarsomeres brownish yellow. Forewing (Figs. 1, 355): Length 6.0 – 7.1 mm (n = 52), brownish yellow intermixed with few brownish­orange and few darkbrown scales; cell and surrounding areas paler than marginal areas; cell with 2 dark­brown spots, 1 spot near middle, 1 spot near distal end; middle spot large or small, present or absent; distal spot small; a small spot on CuP basiposterior to midcell spot present or absent; margin brownish yellow or demarcated with dark­brown scales. Undersurface brown intermixed with brownish­yellow scales along costal margin; venation with R 3, R 4, and R 5 approximate to dorsoanterior part of cell; M 2 and M 3 approximate to dorsoanterior part of cell; M 1 absent; CuA 1 and CuA 2 branched distad of Cubitus beyond cell, extending in a slight curve to margin; CuP slightly evident basally. Hindwing (Fig. 1): Brownish gray; venation with Rs and M 1 stalked about 1 / 3 length beyond end of cell; M 2 closer to M 3 than to M 1; M 3 branched with CuA 1 beyond cell, about 1 / 4 distance as Rs and M 1; CuA 2 arising from cell about 2 / 3 length of Cubitus; 1 A and 2 A separate basally, forming an elliptical support.

Abdomen (Fig. 204): Male with 3 transverse, irregular rows of sex scales on intersegmental membrane between terga 2–3.

Male Genitalia (Figs. 205–206): Uncus elongate, wide at base, broadly constricted near 1 / 3, narrowly parallel­sided apically, apex narrowly rounded and setose; gnathos sparsely setose, protuberant, wide throughout length, apically upturned; tegumen slightly widened basally; dorsal strut of tegumen with arms convergent, fusing medially from posteroventral margin, extending to base of uncus; costa of valva nearly straight from shallow depression beyond basal, digitate process to dorsal furca; apex widely bifurcate, margin between furcae U­shaped; dorsal and ventral furcae large, divergent, equal in size, greatly extended beyond outer margin of cucullus; sacculus apically twisted, constricting valva slightly before midlength, widening distoventrally, forming an elongate, broadly rounded cucullus; cucullus membranous and setose; vesica of aedeagus sparsely denticulate, bearing a large crescent­shaped, apical cornutus; cornutus with one side slightly shortened, exposing a hollow, basal cavity.

Female Genitalia (Fig. 286): Papillae anales elongate, wider basally than apically; apophysis posterioris and apophysis anterioris about equal in length; eighth sternum and eighth tergum about equal in width; eighth sternum with posterior margin broadly rounded, anterior margin broadly emarginate; eighth tergum with posterior margin nearly straight, anterior margin broadly emarginate; antrum enlarged posteriorly from a constricted anterior end, posterior margin slightly rounded, posterolateral margin angular; anterior end with a pair of elongate, spinelike processes inside cavity formed from outer wall; ductus bursae short; corpus bursae slightly enlarged anteriorly, sparsely denticulate; ductus seminalis short, about 5 ­coiled, each coil decreasing in size distally; ductus seminalis with a short, 4 ­coiled internal support; side opposite ductus bursae slightly swollen, with a large, internal support.

Distribution (Map 37): Glyphidocera vappae appears cosmopolitan in Costa Rica and likely is distributed more widely throughout Central America and possibly into South America.

Etymology: The species epithet vappae is derived from the Latin “vappa,” meaning sour vine.
