Diagnosis - The new species belongs to the Stenoloba manleyi species-group, representing the allopatric sister species of the Vietnamese S. bachmana KONONENKO et RONKAY, 2000. The two species are easily distinguished by their external and genital features as S. pulla has much darker wings than its sister species, and the forewing pattern is much more diffuse, less distinct and conspicuous than in S. bachmana. The male genitalia of the two species are of similar type, but those of S. pulla (Fig. 7) are much broader at basal (saccular) half, with almost parallel costal and ventral margins, the cucullus is rather angular, with longer, narrower field of sclerotized setae, the valvae are more asymmetrical, right valva larger, broader, the aedeagus is shorter, much more thickened at middle and the cornutus is stronger, more than two times longer than those of S. bachmana (Fig. 9). The female genitalia of the two sister species are more similar but the rate of the antrum and the ductus bursae is different in the two taxa, as the antrum is somewhat shorter, the ductus is longer in S. pulla (Fig. 8), their rate is about 1.25:1 while the antrum is significantly longer, almost twice as long in S. bachmana (Fig. 10). The new species resembles also the dark forms of S. manleyi formosana KONONENKO et RONKAY, 2000, and S. lichenosa KONONENKO et RONKAY, 2001, occurring sympatrically with S. pulla in Taiwan. The most conspicuous difference between them is the much narrower reniform stigma of S. pulla, marked with a
