Species of Emphylica have a conical frons (Figs 2–5), similar to species of Achyra, Loxostege and Sitochroa (Figs 6–10), and by this differing from most genera of Pyraustinae. They can be best distinguished from the genera mentioned above in male genitalia by the narrowly triangular to trapezoid, sparsely to moderately setose uncus, the scale-liked editum, the sclerotized ventral process of the sella pointing towards the ventral margin of the valva, the nearly U-shaped juxta, the well-developed, distally rounded saccus, and the interlaced spicules in the phallus. In female genitalia, the antrum is sclerotized and the signum is rhombic.

Emphylica diaphana resembles other Emphylica species in the conical frons and the scale-like setae of the sella. It can be best distinguished from its congeners by the whitish ground colour suffused with pale brown scales on both wings, the dark brown lines at termen, in male genitalia by the triangular, distally narrowly-rounded uncus bearing only few short setae and the long, strongly sclerotized ventral sella usually projecting beyond the ventral margin of the valva. In female genitalia of E. diaphana, the antrum is strongly sclerotized, shorter than the length of the anterior apophysis, slightly wider than the ductus bursae; the maximal length of the signum is approximately 2/3 as long as the diameter of the corpus bursae; the two opposing angles of the signum without carinae are well-developed, almost as long as the other two. In E. xanthocrossa the antrum is broad, lightly sclerotized, no more than twice as wide as the ductus bursae; the two opposing angles of the signum without carinae are fairly short; in E. crassihamata the antrum is longer than the anterior apophysis, in E. cruoralis the antrum is as long as the anterior apophysis and the signum of both species is small (less than half of the diameter of the corpus bursae).

Juxta plate-shaped with lateral part strongly sclerotized, distal half slightly divided medially. Phallus tubular, straight, approximately 4/5 as long as length of valva, distal half with interlaced spicules, distal end dorsally with several small, teeth-like spines. Female genitalia (Fig. 20). Anterior apophysis with triangular expansion near basal third. Antrum cup-shaped, slightly wider than ductus bursae, medially somewhat constricted.

This species was formerly placed in the genus Loxostege, probably based on the conical frons. However, genitalia traits of Loxostege moths, e.g. the cylindrical uncus with dense, scale-like setae, the few hair-like setae of the dorsal sella, the ventrobasally directed ventral sella and the usually coiled ductus bursae, are different in Emphylica diaphana. Although in appearance the wing colour and pattern of this species are somewhat dissimilar to those of other Emphylica species, the genitalia traits agree with the diagnostic characters of Emphylica xanthocrossa Turner, the type species. Moreover, according to the molecular phylogeny, this species was inferred as terminal lineage within Emphylica, rather than in Loxostege. Consequently, this species is considered as correctly placed in Emphylica.

In appearance, E. crassihamata resembles E. cruoralis in the reddish brown subterminal band, but can still be recognized by the predominantly yellow basal 2/3 of the forewing sprinkled with reddish brown scales and the presence of a faint antemedial line on the forewing and postmedial lines on both wings. In male genitalia it differs from E. diaphana and E. xanthocrossa by the distally rounded, moderately setose uncus, the pointed and recurved dorsal process of the sacculus, and the long and slender phallus, which is longer than the length of the valva; from E. cruoralis it differs by the wider distal uncus, the small triangular, strongly sclerotized process near the distal sacculus as well as the hook-like ventral sella. In female genitalia, the sclerotized antrum is approximately 1.5× as long as the anterior apophysis whereas in E. cruoralis the sclerotized antrum is as long as the anterior apophysis.

Valva evenly wide medially, slightly tapering towards apex, with a small triangular sclerotized process beyond distal end of sacculus; transtilla triangular; costal sclerotized band wide, slightly expanded to 2/3 of dorsal margin; sacculus broad, distal third expanded and bearing a strongly sclerotized, hook-like process; dorsal sella quadrate; ventral sella hook-like, strongly sclerotized. Juxta U-shaped with two slender arms, thickened and fused in basal half. Phallus long and slender, slightly curved upward, approximately 1.25× length of valva, distal half with interlaced spicules on vesica, distal end with several pointed cornuti dorsally. Female genitalia (Fig. 21). Anterior apophysis slightly bulging near basal third. Antrum long, funnel-shaped, thickened and strongly sclerotized distolaterally, approximately 1.5× as long as anterior apophysis.

Emphylica cruoralis resembles E. crassihamata in the reddish brown subterminal band and the saffron fringe. The differences between the two species are provided in the diagnosis of E. crassihamata. In appearance, E. cruoralis can be best recognized within the genus by the yellow postmedial band of the forewing, in male genitalia by the narrow trapezoid uncus with hair-like setae at distal third, the large, thumb-shaped, weakly sclerotized process of the ventral valva near the distal sacculus as well as the triangular ventral sella overlaid by a folded, distally blunt process. In female genitalia, it resembles E. crassihamata except for the less sinuate distolateral antrum and the relatively shorter and wider antrum anteriorly.

This species was formerly placed in the genus Pyrausta. However, both the molecular phylogeny and the genital traits suggested that it should be placed in Emphylica. According to the male genitalia (Fig. 18) of the type specimen of Emphylica cruoralis (Warren, 1895), comb. n., this species agrees with diagnostic characters of Emphylica. It differs from Pyrausta by the conical frons, in male genitalia by the the presence of an editum made of modified, scale-like setae, the more anteriorly positioned and ventrally directed and sclerotized sella, and the more strongly developed sclerotized dorsal process of the sacculus, and in female genitalia (Fig. 22) by the strongly sclerotized antrum.

Emphylica xanthocrossa resembles E. crassihamata and E. cruoralis in the saffron fringe, the conical frons and the U-shaped juxta. It can be best distinguished from its congeners by the smaller wingspan (less than 15 mm), the triangular saffron spot on the forewing costa postmedially, the smoky brown subterminal margin of the hindwing, in male genitalia by the distally concave uncus, the spinulose ventral sella, the absence of a dorsal process on the sacculus, the larger juxta, the broad and slightly sinuate phallus and the ductus ejaculatorius originating from the middle of the phallus. In female genitalia, the antrum is moderately sclerotized, bottle-shaped, the two opposing angles of the signum without carinae are short, whereas in E. diaphana, E. crassihamata and E. cruoralis the antrum is strongly sclerotized and the two opposing angles of the signum without carinae are almost as long as the other two.
