( Figs 153–177 )

Type material. Holotype: Ô, HONDURAS: Copán Department, Copán, 14°50’13”N, 89°08’37”W, elevation 620 m, mining larva on Sapindaceae 15.ii.2012, ex pupa iii. 2012, field card no. 5089, leg. A. Diškus, genitalia slide no. AD537 ( MfN) . Paratypes: 1 Ô, 1 ♀, same label data as holotype, genitalia slides nos AD528Ô, AD1091 ♀ (MfM); 4 Ô , 1 ♀, same label data, genitalia from adult in pupal skin, without pinned adults preserved, slide nos AD 529Ô, AD 538Ô, AD 551Ô ( MfN) .

Diagnosis. Externally, this new species can be confused with other sparsely speckled Tischeriidae species. In the male genitalia, the unique shape of the phallus as well as the combination of very slender uncus and the long anterior process of vinculum make C. sapindoidum sp. nov. immediately recognizable. In the female genitalia, is also distinctive because of the combination of large coils of ductus spemathecae, greatly folded and thickened accessory sac, and long lateral lobes of ovipositor.

DNA barcode. Unavailable.

Description. Male ( Figs 153, 155 ). Forewing length 2.5–2.8 mm; wingspan 5.5–6.1 mm (n = 2). Head: frons glossy golden cream; pecten yellowish cream with some dark brown scales; frontal tuft yellowish cream, golden glossy; collar comprised of slender lamellar scales, pale ochreous yellow, golden glossy; antenna approximately about one half the length of forewing; flagellum ochreous yellow, glossy, with some pale brown scales on upper side. Tegula and thorax pale ochreous yellow, glossy. Forewing with blue and purple iridescence, pale ochreous yellow, sparsely speckled with black-brown scales; fringe pale ochreous yellow, with an indistintive fringe line comprised of brown-black scales; forewing underside brown. Hindwing pale grey to cream or slivery shiny, depending on the angle of view; on underside, hindwing pale brown, without androconia; fringe ochreous cream. Legs ochreous cream, glossy, speckled with grey-brown scales on upper side. Abdomen densely speckled with brown scales on upper side, ochreous yellow with some dark brown scales on underside; genital plates ochreous yellow; anal tufts indistinctive (or rubbed).

Female ( Figs 154, 156–158 ). Forewing length 2.8–2.9 mm; wingspan 6.0– 6.1 mm (n = 2). Otherwise, similar to male.

Male genitalia ( Figs 159–164 ) with capsule 385–415 µm long, about 255 µm wide. Uncus comprised of two very slender and long lobes. Socii large, weakly paired, densely covered with minute spines. Tegumen moderately short, without spines. Valva about 245 µm long, almost gradually tapering towards apex; basal processes slender, relatively long. Anellus indistinctive. Vinculum very short, with a very slender and long anterior process. Phallus 690–700 µm long, very slender but wide apically; apex thickened laterally and with a prominent, pointed, median process.

Female genitalia ( Figs 165–169 ) ca. 3410 µm long. Ovipositor lobes relatively large, rounded, densely covered with peg-like setae; second pair of ovipositor lobes almost of the same size as the main lobes but with numerous long setae; lateral lobes distinctly long ( Fig. 169 ). Anterior and posterior apophyses equal in length; prela comprised of three pairs of unique, rod-like projections; inner prela very slender and long. Corpus bursae long; pectination indistinctive or absent. Ductus spermathecae with about 13–15 very large coils.

Bionomics ( Figs 170–177 ). Host plant is Serjania Mill. (or Paullinia L.), Sapindaceae ( Figs 170–172 ). Larvae mine leaves in February. The blotch-like mine is irregular, but usually elongated, whitish and transparent, without frass. Usually leaf mines are close to the leaf margin and the mining larva folds a margin of the mined leaf before pupation. The nidus is invisible through the epidermis, so dissection of the mine is necessary to see the nidus.Adults occur in March.

Distribution. This species is known from a single locality in Honduras, Copán Department, Copán, at the elevation of 620 m.

Etymology. The species is named after the tropical host-plant subfamily Sapindoideae , in reference to its feeding on Serjania Mill. (or Paullinia L.), Sapindoideae , Sapindaceae .
