Diplopseustis Meyrick, 1884: 284 - 285 View in CoL .

Type species: Cymoriza minima Butler, 1881 , by subsequent designation by Aurivillius, 1885, Zool. Jahresbericht, II. Abt. (1884), Arthropoda: 526

Diagnosis. The genus can be separated from Sufetula by characters from the forewings and male and female genitalia. The forewing of Diplopseustis moths displays small dots interspaced between the three larger spots along the costa, extended between the antemedial and postmedial lines, and the antemedian and postmedian lines are very thin. The hindwing lacks the antemedian and median markings, and the transverse line runs in the postmedian or subterminal area rather than in the median area as in Sufetula . Vein Rs 4 of the forewing diverges from the stalk of Rs 2 and Rs 3 at least 1/4 along its distance from the cell. Veins M 2 and M 3 are stalked in both the forewing and the hindwing. Posterior of the sacci tympani are puteoli that are separated from the posterior part of sternum II by a low, narrow ridge. In the male genitalia, the uncus is very thin and elongated. The valva has various shapes but is generally longer than wide. In the female genitalia, the corpus bursae is ovoid to oblong, without a signum.

Distribution and diversity. Diplopseustis is currently known from the Oriental, Australasian ( Australia, New Guinea) and Afrotropical regions. The genus currently includes seven species: Diplopseustis brunnealis (Hampson, 1917) comb. nov., D. constellata Warren, 1896 , D. nigerialis Hampson, 1906 , D. pallidalis Warren, 1896 , D. perieresalis ( Walker, 1859) , D. prophetica Meyrick, 1887 , and D. selenalis Hampson, 1906 . Diplopseustis brunnealis is the only species currently known from the Philippines.

Phylogenetic relationships. Diplopseustis was recovered as monophyletic together with Sufetula in Léger et al. (2021). The two Sufetula species S. diminutalis (Walker, 1866) from Central America and S. sythof fi (Snellen, 1899) from South-East Asia included in the phylogenetic analysis of Léger et al. (2021) cluster together.
