Pantana Walker

Type species: dispar Walker = visum Hübner, S.E. Asia, Sumatra.

In facies, species of Pantana are not dissimilar from those of Laelia, but have general differences as discussed for Laelia and below, particularly with regard to the position and intensity of darker spots on the forewing: these are adjacent to the cell. The build is also more delicate, the wings generally broader.

The male abdomen lacks tymbal organs. The genitalia have a short, rather triangular uncus, no gnathus, and a broad, shallow saccus. The valves are squarish, though sometimes with one or both the distal angles produced. The aedeagus is straight, with a variably scobinate vesica, and often has a ventral digitate process centrally.

In the female the pseudopapillae are narrow as in Laelia. The ductus has the ostial funnel densely scobinate, and the short section to the ductus seminalis rather fluted, and coiled once. The bursa is pyriform with a small central signum, a finely scobinate sclerotised disc, sometimes slightly indented.

Wang (1993) illustrated the larva of a Taiwanese species. It is a pale rusty orange with long secondary setae on verrucae and the usual four dorsal brushes of the Orgyiini. Host-plants noted were all Gramineae.

The genus is diverse in the Oriental tropics to Sundaland and, with several endemics, the Philippines. It is not known from Sulawesi but has an outlier in the S. Moluccas.
