Caeneressa Obraztsov

Type species: diaphana Kollar.

This genus was erected by Obraztsov (1957a) to embrace a large number of Oriental species that had previously been misplaced in Amata or in Eressa Walker. Eressa sensu stricto was reviewed by Obraztsov (1954), and is discussed above.

The wing venation of Caeneressa (Fig. 3) has already been discussed on Subfamilies Syntominae and Euchromiinae. In the hindwing it resembles that of Eressa. In the forewing pattern there is usually only a single transparent zone or pale patch in the space posterior to CuA2.

In the male genitalia the valves are usually broad, long, simple, unornamented, often with the saccular bases fused to a small central, triangular sclerite (the juxta), or one shaped like an inverted V, (also seen in Eressa). The valve is typically very slightly constricted centrally. The aedeagus vesica is usually simple with scobination general throughout, or in an extensive field.

In the female genitalia the ostium usually intrudes into the posterior margin of the seventh sternite. There is a single signum set ventrally, centrally in the bursa, elongate longitudinally, with the lateral scobination stronger than that in the centre.

In Borneo there is a large number of species, including the type species. Most fall within a distinctive Sundanian group with rather dark facies, defined by white basal spots on the tegulae (robusta to longipennis). A number of small species are also included for reasons given in each case, though in some instances this placement may have to be reviewed when further material becomes available.
