Fulgora philippina – BAKER, 1925: 349 [keyed], 351 [described based on specimens from Samar Island], pl. 1, fig. 5 [dorsal view], pl. 2 fig. 3 [lateral view] (based on misidentified specimens!)

ETYMOLOGY. The species epithet, auratus (adj., Latin) means “golden” and refers to the extended bright yellow area of the posterior wings.

MATERIAL EXAMINED. TYPE MATERIAL. PHILIPPINES, Samar: Holotype ♂ ( Fig. 1 ): [Coll. I.R.Sc.N.B., Philippines , Samar, Hinabangan , 11°42’N, 125°04’E, xi.2004, local collector, I.G.: 32.907] ( RBINS).

DIAGNOSIS. This species can be separated from all other species of Pyrops by the following combination of characters:

(1) posterior wings bright yellow with narrow black band along apical margin ( Fig. 1 A );

(2) cephalic process elongate, weakly curved and weakly narrowing from base to mid-length, then weakly widening towards apex in dorsal view ( Fig. 1 C, E–F );

(3) head with vertex castaneous, frons, ventral half of genae and proximal portion of cephalic process ventrally pale yellowish, dorsal part of genae to anteocular carina black, cephalic process green with apex yellow ( Fig. 1 C, E–F );

(4) tegmina green with three transverse yellow bands on proximal half, the most distal one interrupted; two additional yellow markings in costal area; cells black in a marginal area extending from distal half of costal area, along distal margin, to apex of clavus; about 12 round yellow spots in distal zone of black cells; 4–5 yellow spots in green portion of distal half ( Fig. 1 A, D ).

DIFFERENTIAL DIAGNOSIS. The most similar species is P. nishiyamai Nagai & Porion, 2002 ( Fig. 4 ) from which P. auratus sp. nov. differs by its more robust (LPr/BPrH = 7.56 vs 10.6 in P. nishiyamai ) and mostly green cephalic process (mostly brown in P. nishiyamai ), the yellow transverse bands of the tegmina (only yellow spots on tegmina of P. nishiyamai ) and the wider area with black cells along apical margin. Pyrops philippinus ( Stål, 1870) ( Figs 5–8 ) somewhat resembles P. auratus sp. nov. but can be separated at first glance by the black area of posterior wings covering distal 1/3 (only a narrow black band along apical margin in P. auratus sp. nov.).

DESCRIPTION. Measurements and ratios: TL: ♂ (n = 1): 35.1 mm; TL+process: ♂ (n = 1): 47.9 mm; LTg/BTg = 2.62; BF/BPrH = 2.37; LPr/LF = 3.25; LPr/BPrH = 7.56.

Head: ( Fig. 1 C, E–F ) vertex castaneous basally with sides blackish; frons, ventral half of genae and proximal portion of cephalic process ventrally pale yellowish; dorsal part of genae to anteocular carina black; cephalic process green with apex yellow; cephalic process with spots of white wax; clypeus pale yellowish with apex slightly darker; labium and antennae black; ocelli yellowish. Cephalic process elongate, weakly curved and weakly narrowing from base to mid-length, then weakly widening towards apex in dorsal view; dorsal and ventral margins subparallel in lateral view. Two longitudinal carinae on frons extending on sides of cephalic process up to apex. Median, ventral carina on distal 2/3 of cephalic process. Frons subquadrate. Clypeus elongate with smooth median carina. Labium shortly surpassing posterior trochanters.

Thorax: ( Fig. 1 C, E–F ) pronotum pale yellowish with descending oblique black line on paranotal lobes; mesonotum castaneous, slightly paler towards scutellum and with black spot on each side along posterior margin; tegulae pale yellowish. Pronotum very weakly wrinkled with two impressed points on disc, without median dorsal carina and with weak, incomplete oblique lateral carinae; paranotal lobes with two carinae behind eye. Mesonotum smooth, weakly wrinkled on disc, with obsolete median and lateral oblique carinae

Tegmina: ( Fig. 1 A, D ) green with three transverse yellow bands on proximal half, the most distal one interrupted; two additional yellow markings in costal area; cells black in a marginal area extending from distal half of costal area, along distal margin, to apex of clavus; about 12 round yellow spots in distal zone of black cells; 4–5 yellow spots in green portion of distal half. Tegmina elongate, broadening from base to nodal line, with costal margin broadly rounded, apical margin obliquely rounded and apical angles rounded.

Posterior wings: ( Fig. 1 A–B ) bright yellow with narrow black band along apical margin; veins concolorous with background. Hind wings strongly broader than tegmina.

Legs: ( Fig. 1 A–B ) all coxae, trochanters and femora brownish red; pro- and mesofemora darker than metafemora; tibiae and tarsi black weakly tinged with reddish. All legs slender and elongate. Pro- and mesofemora broader than corresponding tibiae. Metatibiae with 7 lateral spines.

Abdomen: ( Fig. 1 A–B ) terga yellowish; sterna brown with segments darker towards apex; anal tube and genital segments brown.

Male terminalia: ( Fig. 2 ) brown with anal tube darker and a paler oblique area on basidorsal portion of gonostyli. Pygofer higher than long, with posterior margin sinuate in lateral view ( Fig. 2 A ) and bisinuate ventrally ( Fig. 2 E ). Gonostyli ( Fig. 2 A, E ) elongate, 1.50 times longer than high in lateral view, not surpassing apex of anal tube, with dorsal margin broadly rounded and apical margin with weak posterior projection; lateral hooks of gonostyli short, pointing anteroventrally ( Fig. 2 A, E ). Aedeagus membranous with pair of elongate ventral endosomal processes widening on distal half ( Fig. 2 C–D, F ). Anal tube elongate ( Fig. 2 A–B ), 1.25 times longer than broad in dorsal view, broadest at half of total length ( Fig. 2 B ); lateral margins

broadly rounded, subparallel for a distance along distal half ( Fig. 2 B ) and apical margin deeply, roundly notched in dorsal view ( Fig. 2 B ).

DISTRIBUTION. Philippines: Samar Island ( Fig. 3 ).

BIOLOGY. Unknown.
