Park, Kyu-Tek & Lee, Sangmi, 2012, Two new species of the Torodora karismata species complex and a new species of the Torodora leucochlora species complex (Lepidoptera: Lecithoceridae: Torodorinae), Zootaxa 3547, pp. 46-54 : 48-49

Torodora parakarismata Park , sp. nov.

( Figs. 1, 1 a, 4, 6, 6a–b)

Holotype. ♂, Indonesia, Sumatra U. Mount. Simasopa 15 km west Sindaraya 28 viii1992 400m, JB Heppner & EW Diehl, gen. slide no. CIS-6146/Park. Type is deposited in the McGuire Center for Lepidoptera and Biodiversity, Florida Museum of Natural History, University of Florida, Gainesville, Florida, U.S.A.

Diagnosis. The new species closely resembles T. karismata Park , but can be distinguished by the following characters: the largest whitish costal patch at the middle of the forewing is narrow, with length more than two times the width, and extended beyond lower margin of the cell, followed by three more distinct smaller, evenly spaced patches before the large apical patch. In T. karismata , the largest median patch is broad, length less than 1.5 times of its width, not reaching lower margin of cell, followed by three smaller patches before large apical patch, of which the middle one is very small and much closer to the first one. The male genitalia provide a good separable character with the different shape of juxta as in Figs. 6 a and 7a.

Description. Male ( Fig. 1, 1 a, 4). Wingspan 13 mm. Head brownish, partly mixed with silvery-white scales dorsally, and with a row of broad orange-white scales along posterior margin; frons shiny silvery white. Collar well-developed, dark brown in basal 1/3, then orange white beyond, mixed with brownish scales medially. Antenna more than 1.3 times length of forewing; basal segment slightly dilated apically, dark brown dorsally, orange white ventrally; flagellum shiny orange white throughout, without annulations. Second segment of labial palpus thickened with rough scales ventrally, dark brown on outer surface, orange white centrally in basal half on inner surface; 3rd segment as long as 2nd segment, orange white dorsally, dark brown ventrally. Tegula dark brown, mixed with orange-white scales posteriorly. Thorax dark brown, irregularly mixed with orange-white scales. Forewing elongate; ground color dark purplish brown, with various shapes and sizes of whitish costal patches: largest patch at middle, quadrate, narrow, length more than twice width; second larger one prior to apex, triangular; third larger one at ¼ length of costa, preceded by two smaller ones and followed by smallest one; three other smaller ones followed by the largest costal patch; discal stigma small, orange white, near end of cell; terminal fascia dark brown, along termen; apex obtuse; termen oblique; fringe dark brown around apex, then orange white in 3/5 length, partly mixed with brownish scales, dark brown beyond 3/5 length; venation similar to that of T. karistmata . Hindwing dark purplish brown, with large whitish patch near apex. Hind tibia clothed with brownish scales dorsally, shiny silvery-white ventrally. Female unknown.

Male genitalia ( Figs. 6, 6 a, 6b). Uncus broad basally and narrowed towards apex, slightly longer than basal stalk of gnathos, with round apex. Median process of gnathos large, bent preapically. Valva broad basally, narrowing toward middle; costa strongly angled medially; cucullus elongate, slender, nearly parallel sided, densely setose; apex obtuse; ventral margin gently arched. Juxta deeply concave on caudal margin; caudal processes heavily sclerotized, gently bent, outward, with acute apex. Vinculum heavily sclerotized, band-shaped. Phallus stout, shorter than valva, broadened basally, slightly narrower towards apex; apex produced, with apical processes of two different lengths.

Distribution. Sumatra, Indonesia.

Etymology. The species is named for its resemblance to the preceding species, T. karismata Park.
