038C1730FFEBFFD723AACE24C751F98F.taxon	diagnosis	DIAGNOSIS. All known species of Malesia are characterized by small size and similar external appearance. Forewing narrow, ochreous. Forewing pattern includes two rounded black spots in the middle and at the end of the discal cell and a dark oblique band in the postmedial area; in some specimens, a dark discontinuous transverse band in the submarginal area. Hindwing translucent. Antenna bipectinate in male, filiform in female. In male genitalia uncus long, slender, slightly extended at tip. Tegumen broad, v-shaped. Valva elongate, costa with distal process (absent in M. cana Černy, 2014). Distal saccular process present only in M. cana. Aedeagus straight, short, broad, tapering distally (except in M. cana, where aedeagus is longer and thinner). Vesica long, with a longitudinal ridge with a series of spine-like cornuti (except in M. cana, where vesica is short and broad with other arrangements of cornuti and scobination).	en	Koshkin, E. S.

038C1730FFE8FFD222BACB6CC10FFE22.taxon	diagnosis	DIAGNOSIS. The new species clearly differs from the other congeners in the peculiarities of the structure of the male genitalia – the presence of a hook-like distal process of the costa and a massive spine-like distal saccular process. Apart from Malesia spitsyni sp. n., the distal saccular process is present only in M. cana Černy, 2014, where it is strongly curved and the costa lacks any processes. The distal costal process is also present in M. eugoana van Eecke, 1920, M. tanahratana Bucsek, 2012, and M. luzonao Černy, 2014, but in these species it is bifurcated (in M. spitsyni sp. n. it is not bifurcated and looks like a slightly curved hook). The aedeagus of the new species is short and broad, tapering distally, as in M. eugoana, M. tanahratana and M. luzonao. The size of the cornuti in M. spitsyni sp. n. is larger than in the above species. Externally, M. spitsyni sp. n. has no clear differences from other Malesia species, and is the same size as M. eugoana, which is the largest species in the genus.	en	Koshkin, E. S.

Abdomen gray on upperside, pale ochreous laterally and on last segments. Femurs gray, rest of legs light ochreous. Forewing narrow, ground color pale ochreous, with heavy diffuse dusting of dark brown scales. Two large rounded black spots in middle and end of discal cell.
