Mireana tawitawiensis Park & Kim View in CoL , sp. nov.

( Figs. 2 View FIGURE 2 A–J)

Type material. Holotype: ♂, Philippines, Tawi Tawi , Tarawakan, North of Batu Batu, 22 Oct. 1961, Noona Dan Wxp. 61–61. Caught in Malaise traps, gen. slide no. CIS-7412, in ZMUC.

Paratypes: 2♂, same locality, 13 & 16 Nov. 1961, gen. slide no. 6201, -7410 ; 1♀, Mindanao, Sapanmoro, Ce- ruan Dist., 21 Dec. 1961, Noona Dan Wxp. 61–61. Caught in Malaise traps, gen. slide no. CIS-7413, in ZMUC .

Diagnosis. This species is externally similar to Ephalista batillosa sp. nov. in the wing coloration, but it can be easily distinguished by the up-curved labial palpus and the absence of fuscous scales at apical part of forewing.

Description. Male. ( Figs. 2 View FIGURE 2 A–C). Forewing length 5.5–6.0 mm.

Head: vertex shiny mustard brown, covered with pale-yellow scales; frons pale yellow. Antenna long, longer than 1.3 times length of forewing with basal segment elongated, pale yellow; flagellum pale yellow, without annulation, pale brownish gray in discal 2/5; second segment of labial palpus long, thickened ventrally, arched, light yellow all around; 3rd segment slender, as long as 2nd segment, light yellow, with acute apex.

Thorax: Tegula is light yellow to light orange dorsally. Hind tibia light yellow, with blackish scales at apex. Forewing ground color pale yellow; with broad, grayish-brown antemedian fascia, occupying more than 1/3 of the wing; postmedian fascia similar, often not definitely separate from each other; costa slightly expanded anteriorly in basal 2/5; apex obtuse; fringe same as forewing ground color; venation ( Fig. 2C View FIGURE 2 ) with R 1 absent; R 2 arising from near upper angle of cell; R 3 and R 4 stalked for about basal half; R 4 reaching prior to apex; R 5 absent; M 1 arched basally, directing to base of R 3+4; M 2 absent; M 3 and CuA 1 coincident, arising from near lower corner of cell; CuA 2 nearly parallel to M 3 +CuA 1; cell weakly closed. Hindwing as wide as forewing; ground color paler than that of forewing; apex produced; fringe concolorous with ground color; venation Rs and M 1 connate; M 2 absent; M 3 approximated to CuA 1; cell opened.

Abdomen: Male with broad spinous zones on dorsal surface; sternite VIII with broad expansion medially. Female with abdominal sternite VIII slightly emarginated medially.

Male genitalia ( Figs. 2 View FIGURE 2 D–H): Uncus long, broadly elongated, bent medially downward, with nearly truncate apex. Median process of gnathos broad basally, bent beyond 2/3. Tegumen deeply emarginated medially on posterior margin, emarginated in V-shape on anterior margin. Valva elongated, slightly narrowed distally, not distinctly bordered with cucullus; cucullus as long as basal part of valva, strongly upturned, with more or less narrowly produced apex, densely setose. Juxta heavily sclerotized, horn-shaped latero-caudal processes, with sharp and acute apices, these caudal processes of juxta demonstrate slight morphological differences which fall within infraspecific variation. Vinculum narrowly banded. Aedeagus slender, gently bent near basal 1/3, as long as valva, with a minute conic spine near apex dorsally and a spine-like process ventrad.

Female genitalia ( Figs. 2 View FIGURE 2 I–J): Ostium bursae concaved on caudal margin medially. Antrum bowl-shaped. Ductus bursae long, coiled once near anterior end; ductus seminalis arising from anterior 1/3. Corpus bursae semi-ovate; signum with anterior margin linear, heavily sclerotized, with dense spinules on surface.

Distribution. The Philippines (Is. Tawi Tawi).

Etymology. The species name is derived from the type locality.
