Macaduma borneana

(x 1.73)

, 9-10mm. The forewing is of typical shape for the genus and is coloured deep rich brown as in many of the species. There is also a characteristic scale tuft at the costal angle. The hindwings are darkish grey, distinguishing the species from tortricella where they are more fawn. The male genitalia in tortricella have the valves broadening to the apex, and the aedeagus vesica is only finely scobinate; in the Bornean species the valves narrow towards the apex, ending in slender spines, bifid on the right, single on the left, and the aedeagus vesica has a distinctive lobe ringed with cornuti directed away from its extremity.
