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

(1) posterior wings pale blue with apex and area along sutural margin black brown, with brown area paler and narrower towards basosutural angle ( Fig. 1 A );

(2) cephalic process elongate, curved and narrowing apically ( Fig. 1 E–G );

(3) head black with frons yellow-brown ( Fig. 1 E–G );

(4) tegmina uniformly with ground colour black and dense reticulum of green veins and veinlets, and with transverse rows of centrally orange white spots ( Fig. 1 A ).

MATERIAL EXAMINED.

TYPE MATERIAL. INDIA, Andaman and Nicobar Islands: holotype ♀ ( Fig. 1 ): [Andamans] [ andamanensis Dist. (Type)] [Distant Coll. 1911—383.] [Type]. ( BMNH) .

ADDITIONAL MATERIAL. INDIA, Andaman and Nicobar Islands: 1♂: Andaman, Distant Coll., 1911—383. ( BMNH) .

ADDITIONAL DATA. INDIA, Andaman and Nicobar Islands: 1 ex. ( Fig. 8 ): Nicobar ( ATKINSON, 1885, 1889).

SUPPLEMENTARY DESCRIPTION.

Male genitalia: brown-black with anal tube darker. Pygofer higher than long, with posterior margin broadly rounded with a ventral projection in lateral view ( Fig. 9 A ). Gonostyli ( Fig. 11 A–B ) elongate, 1.75 times longer than high in lateral view, with posterior margin broadly narrowly rounded and showing a slight lamina dorsolaterally; not surpassing apex of anal tube; lateral hooks of gonostyli strongly projecting laterally, and pointing ventrally at apex ( Fig. 9 A–B ). Anal tube elongate ( Fig. 9 A, C ), 1.15 times longer than broad in dorsal view, broader apically ( Fig. 9 C ); lateral margins slightly sinuate ( Fig. 9 C ) and apical margin strongly notched in dorsal view ( Fig. 9 C ).

DISTRIBUTION. Andaman and Nicobar Islands, without more precision.

NOTE. The species has not been recorded for more than one century. The last record was given by ATKINSON (1885) from Nicobar.
