Maguda Walker

Type species: immundalis Walker, Borneo.

The genus consists of small dark brown boletobiine-like species with narrow forewings and characteristically close antemedial and postmedial fasciae on all wings. These therefore can appear as a double fascia medially, particularly on the hindwing. The male antennae are ciliate. The third segment of the forwardly directed labial palps is approximately half the length of the second, apically acute.

The genus, as currently constituted (Poole, 1989), has several Oriental species, one in New Guinea and (Nielsen
et al., 1996) an undescribed one in Australia.

The male abdomen has the eighth segment more complex than in more typical boletobiines, the sternite having a pair of small coremata in a partial semicircular or rectangular frame anteriorly, that then angles out laterally beyond a small interior lobe to support a further pair of hair pencils. The tergite is similar to that of other boletobiines but more rudimentary in several species. The genitalia have the distal part of the valve flimsy, corematous, but with a complex array of more basal processes.

The female of the type species has the ostium set well within the eighth segment, flanked by a pair of scobinate patches that are slightly pouched. The ductus and bursa are similar to those in
Corsa.
