Krakatauia Enderlein, 1912: 408 View in CoL .

Type species. Psilopus rectus Wiedemann, 1830 , orig. des. Bickel, 1994: diagnosis: 142.

Bickel & Martin, 2020: extended diagnosis: 398.

A recent key to the Australasian Sciapodine genera can be found in Bickel & Martin (2020, p. 381) as well as a key to the species groups of Krakatauia (p. 399).

Krakatauia is not strongly defined by synapomorphies, but forms a probable monophyletic group whose species share the following features in a mosaic of combinations ( Bickel & Martin, 2020): usually abundant setae on the male frons ( MSSC), but absent in the female; male face bulging ( MSSC; not in female), eyes often with pale hairs between facets, pedicel usually with rather short dorsal and ventral setae, fore tibia usually bare of major setae, wing often infuscate, venation sometimes modified, haltere sometimes black in both sexes, male cercus with large ventral clavate arm and short distal digitiform projection, large subtriangular projection present between cercal bases.

Since Krakatauia recta ( Wiedemann, 1830) is the type species of its genus, we can include the species with confidence in that genus. Bickel (1994: 144) attributes K. recta ( Wiedemann, 1830) to the Krakatauia evulgata View in CoL species group. Krakatauia recta was until now the only species of the group with a wide distribution in the Oriental region.
