Diagnosis. The new species ( Figs. 1 View FIGURE 1 – 3. 1 a, b) resembles externally Enispa elataria ( Figs. 3 View FIGURE 1 – 3. 1 a, b), but can be separated from it by more clear reddish colour, E. elataria being usually more yellowish. Also wings are less angled, especially hindwing. The white discal spot of hindwing is feeble in E. rosellaria but quite distinct in E. elataria . Enispa rosellus ( Figs. 2 View FIGURE 1 – 3. 1 a, b) is externally quite different with white patches in fore and hind wings. In rosellaria they are more stripelike.

By male genitalia E. rosellaria ( Fig. 4 View FIGURE 4 – 6. 4 a) is closer to E. rosellus ( Fig. 5 View FIGURE 4 – 6. 4 a) than to E. elataria ( Fig. 6 View FIGURE 4 – 6. 4 a). Unci in E. rosellaria and E. rosellus are alike, as valvae, except for digitate saccular processes, which reach apex of cucullus in E. rosellaria while in E. rosellus there is an incurved costal spine that extends beyond apex of the cucullus. In E. elataria uncus is straight with strong setae, and digitate saccular process is short and slender. Vesica of E. rosellaria has diverticula perpendicular to each other, and has also a batch of scobination in distal part.

Female genitalia of E. rosellaria ( Fig. 4 View FIGURE 4 – 6. 4 c) differ from E. rosellus ( Fig. 5 View FIGURE 4 – 6. 4 c) by broader and somewhat longer antrum. In E. elataria ( Fig. 6 View FIGURE 4 – 6. 4 c) antrum is clearly shorther and v-shaped.

Same closer relation of E. rosellaria to E. rosellus contra E. elataria is shown also in DNA. Genetic distances calculated with K2P method indicate that E. rosellaria and E. rosellus are sister species and that E. elataria is more separated. ( Fig. 7 View FIGURE 7 ).

Description. Wingspan 10–11 mm, males and females same size. Head: Frons and vertex brown, palpi narrow, upcurved close to the head, brown, antennae in male relatively shortly ciliate and female very shortly ciliate. Thorax and abdomen same color as wings. Legs same color as underside, dirty yellowish. Wings pale, heavily marked vinous red, with white indefinite zigzag stripes on both wings, the postmedial line on forewings being strongest. On forewing there is distinctive dark line from centre of costa to middle of outer margin. Distally to white discal spots on both wings there are one or two small black dots. Margins and forewing costa dark brown with dark shining scales, cilia orange-yellow. Underside color light dirty yellowish grey, with darker suffusion on wing margins, especially more so on hind wings. Male genitalia ( Fig. 4 View FIGURE 4 – 6. 4 a–b): Vinculum broad U-shaped, tegumen triangular upside down, with somewhat rounded base. Valvae with incurved costal spine, same length as cucullus. Saccus broad, apically rounded. Uncus basally curved with fine setae and hooked tip. Juxta triangular, weak. Aedeagus short and smooth with tiny scobination distally. Vesica membranous with spiculate batch above base of ductus ejaculatorius.

Female genitalia ( Fig. 4 View FIGURE 4 – 6. 4 c): Apophyses anteriores and posteriores of normal length for the genus. Antrum elongate thick with small, dull spines. Ductus bursae coiled, about as long as corpus bursae.

Bionomy and distribution. The new species occurs in disturbed areas with mixed vegetation. Flight period is all year round, depending on rains. Preimaginal stages are unknown. Caterpillars of Japanese species of Enispa feed on lichens and use lichen fragments for camouflaging ( Sugi, 1987). So far E. rosellaria has been found in Northern-Thailand, Lampang and Chiangmai provinces.

Etymology. Name of new species is a combination of E. rosellus and E. elataria .
