Diagnosis. This is the only known species of Sparganothoides in which the enlarged apices of the socius/ gnathos arms are strongly asymmetrically bilobed with the longer lobe bilobed secondarily.
Description. Male. Head: Frons brownish yellow, smooth scaled, deeply concave; vertex roughened laterally, yellowish brown; two large exoskeletal protuberances between mesal-posterior margins of compound eyes, angled toward middle; a laterally broad, dorsoventrally flattened, bilobed protuberance between antennae, projected anteriorly; broad area of densely packed, short, yellowish brown scales between anterior and posterior protuberances; short, erect, yellowish brown scales between posterior protuberances. Labial palpus yellowish brown mesally, yellowish brown laterally. Antennal scaling yellowish brown. Thorax: Dorsum smooth scaled, yellowish brown with grayish tinge on tegulae, scales long and dense, parted at center, obscuring wide median channel in notum filled with dense row of short white scales mesally and long thin white scales laterally; tegula with clump of small orange or brown pointed scales at apex giving tegula truncate appearance. Forewing length 7.4 mm (n = 1). Forewing costal fold extending less than onehalf wing length (dark grayish brown scales within fold); forewing ground color yellowish brown with grayish tinge basally; ill-defined orange and dark brown transverse striae throughout; five dark brown spots along costa beyond costal fold; distinct, broad, grayish brown pretornal patch from discal cell dorsad, lined with orange and brown scales on basal margin creating sharply contrasting border; indistinct dark brown transverse strigulae in subterminal and terminal areas. Fringe yellowish brown. Hindwing yellowish gray basally and near anal angle; gray beyond, with very faint gray transverse striae visible only in yellowish gray portion near anal angle; patch of gray scales on anal angle. Abdomen: Genitalia ( Fig. 34 View FIGURES 31–36 ; EME slide #5613; Costa Rica, Puntarenas, Estación Biol. Las Cruces, 6 km SE San Vito, Río Jaba; n = 1) with uncus long, curved, widened and triangular subapically with a small subrectangular process apically, with long setae dorsally and short setae in two patches ventrolaterally on widened area; tegumen raised, broadly rounded at base of uncus; socii subtriangular posteriorly, secondary arms long, slender, curved before enlarged, strongly asymmetrically bilobed apices with longer lobe bilobed secondarily; transtilla strongly sclerotized, straight, spines short, numerous over most of posterior margin, enlarged anterior process unreinforced at middle; valva elongate, ovate, without a sclerotized crease, costa convex, sacculus convex, extending to apex of valva, pulvinus absent; phallus pistol-shaped, aedeagus shorter than phallobase, gently curved, convexly curved dorsally, tip attenuate apically, attached to juxta by a short process, vesica with dense bundle of>30 cornuti.
Female. Unknown.
Type material. Holotype: Male: COSTA RICA: PUNTARENAS: Estación Biol. Las Cruces, 6 km SE San Vito, Río Jaba , 1150 m, 20–21.i.1993, J. Powell ( EME).
Immature stages. Unknown.
Biology. This species was collected in secondary forest in January.
Remarks. Sparganothoides polymitariana is one of the most derived species in the genus, possessing several autapomorphies; however, it is convincingly assigned to this species group.
Etymology. The name is derived from the Latin “polymitarius” (= highly wrought or finished).
