Type material. Holotype: male, Camiguin, Mt. Timpoong, agro-eco, 15–20 IV 2010, A. Mohagan. Paratypes: 1 male, same data as holotype; 1 female, Camiguin, Mambajao, road to Katibawasan Falls, 271 m, 09°12.964’N 124°43.176’E, 27 VI 2010, K.B.R. Hill, D.C. Marshall, J. Jones, & A. & D. Mohagan, with voucher label 10. PH.CG.KAT.01, collected at light.

Etymology. The new species is named after the ancient Shilla (or Silla) Dynasty because the median ochraceous mark on the mesonotum is reminiscent of the golden crowns of Shilla.

Measurements of types (n = 2 males, 1 female). Length of body: male 45.4 (44.8–45.9), female 39.1. Length of head and thorax together: male 21.4 (21.3–21.4), female 19.8. Length of abdomen: male 24.0 (23.5–24.5), female 19.3. Width of head including eyes: male 20.1 (19.6–20.5), female 19.0. Width of mesonotum: male 16.8 (16.6–16.9), female 15.4. Width of posterior margin of abdominal tergite 3: male 16.9 (16.4–17.3). Length of forewing: male 54.8 (54.4–55.3), female 54.4. Width of forewing: male 18.2 (17.8–18.6), female 17.5. Wing span: male 125.0 (123.8–126.1), female 125.2.

Description of male ( Fig. 2 ). Head ( Fig. 2 E) black with the following dull ochraceous marks: transverse fascia along anterior margin of head, of which median point expanded posteriad reaching or nearly reaching central ocellus; a pair of sublateral spots on anterior margin of head; a pair of transverse fasciae along lateral parts of posterior margin of head, of which medial end widened anteriad; small median triangular spot (indistinct in holotype) on posterior margin. Distance between lateral ocelli and eyes distinctly more than twice as wide as distance between lateral ocelli. Antenna dark brown but pedicel and scape black. Postclypeus scarcely swollen, black with a median longitudinal ochraceous fascia from anterior margin of postclypeus to about anterior one-third point and narrow transverse castaneous fasciae along transverse grooves (black on transverse grooves in paratype). Anteclypeus black. Mentum dark brown. Labium black, slightly passing beyond posterior margin of midtrochanter. Lorum ochraceous with longitudinal black patch on postero-medial corner. Gena ochraceous with large black patch between postclypeus and eye.

Thorax ( Fig. 2 E, F): Inner area of pronotum black with the following dull ochraceous marks: a median longitudinal fascia, not reaching anterior and posterior margins of the inner area; a pair of large patches across paramedian and lateral fissures and posterior margin of the inner area. Pronotal collar black with a pair of dull ochraceous patches along lateral inner margins and a pair of small, indistinct (distinctly ochraceous in paratype) median transverse brown marks. Mesonotum ( Fig. 2 F) black with the following marks: large three-pronged crownlike median dull ochraceous mark, with inner sides of lateral peaks exactly agreeing with parapsidal sutures, with anterior tips of the three peaks touching anterior margin of mesonotum, with posterior median margin not reaching scutal depressions, and with posterior lateral ends extending posteriad to arms of cruciform elevation; a pair of longitudinal dull ochraceous fasciae between lateral margins of mesonotum and lateral sigilla; a pair of dark brown (castaneous in female paratype) patches filling spaces between the crown-like median mark and the longitudinal fasciae along lateral margins of mesonotum. Cruciform elevation smoked ochraceous (holotype) to smoked brown (paratype). Thoracic sternites mostly grayish ochraceous covered with silvery hairs and white pollinosity.

Legs ochraceous to brown with black marks. Fore-femur with mostly black primary, secondary, and subapical spine and black patches anteriorly and along inner ventral margin. Fore-tibia black. Fore- and mid-tarsi mostly black. Hind metatarsus and mesotarsus black. Hind pretarsus dull ochraceous with black apical part. Fore-, mid-, and hind pretarsal claws mostly black.

Wings hyaline, slightly tinged with yellow, but tinged with deep golden color basally extending up to about basal one-third of medial cell and about basal two-thirds of cubital cell of forewing and about basal half of cubital cells of hind wing, and also apically, on distal part of ulnar cells 1 and 2, entirely on apical cell 1, and partly on apical cell 2. Forewing venation reddish ochraceous but castaneous to dark castaneous distally. Radius and subcostal veins reddish ochraceous basally but fuscous distally. Forewing with smudged infuscations on radial and radiomedial crossveins. Basal cell fuscous centrally. Basal membrane gray or grayish ochraceous. Hind wing jugum ochraceous.

Operculum ( Fig. 2 G) orange; triangular with apex narrowed and slightly curved inwardly, extending to sternite V. Opercula slightly overlapping medially.

Abdomen obconical in dorsal view, slightly longer than head and thorax together; mostly black with ochraceous marks on lateral margins and a pair of sublateral rectangular white spots on tergite 3. Timbal cover ochraceous laterally. Abdominal sternites smoky ochraceous or ochraceous. Sternite VIII with median longitudinal smoky brown fascia.

Genitalia ( Fig. 2 C, D): Pygofer long ellipsoidal in ventral view. Uncus simple, long, slender, not bifurcate, inwardly bent in lateral view. Aedeagus about as thick as uncal lobe. Dorsal beak elongated narrowly.

Description of female ( Fig. 3 ). Mesonotum ( Fig. 3 B) with marks similar to those of males except a pair of castaneous (dark brown in males) patches filling spaces between the crown-like median mark and the longitudinal fasciae along lateral margins of mesonotum. Operculum ochraceous with anterior lateral margin black and covered densely with white pollinosity; nearly rectangular. Abdomen obconical in dorsal view, slightly shorter than head and thorax together. Abdominal sternites ( Fig. 3 C) ochraceous with irregular small fuscous to black spots and densely covered with white pollinosity only laterally. Abdominal segment 9 black dorsally and ochraceous ventrally. Ovipositor sheath fuscous, not protruding beyond abdominal segment 9.

Remarks. This species is very similar to Cryptotympana consanguinea but is distinguished by the following characteristics: head and pronotum comparatively much wider, with 1.58–1.77 [about 1.46 in C. consanguinea ] for the ratio of width of head including eyes to length of head and pronotum together; inner area of pronotum with a pair of large dull ochraceous [castaneous in C. consanguinea ] patches; mesonotum with median crown-like mark (with flat bottom side) [W-shaped mark (with a median incision from the bottom side of the mark) in C. consanguinea as illustrated in fig. 6 by Hayashi (1987)], which is dull ochraceous [castaneous in C. consanguinea ]; wings tinged with deep golden color [smoky brown in C. consanguinea ] basally; radius and subcostal veins reddish ochraceous [light green in C. consanguinea ] basally; forewing infuscations on radial and radiomedial crossveins much more smudged and indistinct than in C. consanguinea ; male operculum with apex much more narrowed than in C. consanguinea .
