Labrundinia kogilamae Silva View in CoL sp. n.
( Fig. 30 View FIGURES 30 A – M )
Material examined. Type material: Holotype male, Brazil: São Paulo, São Carlos, Monjolinho stream, associated with the aquatic macrophyte, Myriophyllum aquaticum , 12.iii.2008, F. L. Silva ( MZUSP). Paratype: 1 male same data as holotype ( NTNU).
Etymology. Named in honour of Kogilam Maistry from Cape Town, in recognition for her friendship, kindness and continuous support.
Diagnostic characters. Labrundinia kogilamae sp. n. differs from other Labrundinia species by the combination of the following characters. Adult male: wing length 1.32–1.45 mm; R2+3 absent; abdominal tergites II–VI with continuous brown transverse band near proximal margin, T VII–VIII completely brown; hypopygium brown, sternapodeme with distinct anterior process.
Description. Adult male (n = 2 unless otherwise stated)

Coloration. Head pale brown with dark brown occipital margin; pedicel, antenna and maxillary palp pale brown. Thorax completely brown. Wing membrane transparent without any marking. Legs brown. Abdominal tergites II–VI with continuous brown transverse band near proximal margin, T VII–VIII completely brown; hypopygium brown ( Fig. 30L View FIGURES 30 A – M ).

Adult female, pupa and larva. Unknown.
Remarks. Adult males of Labrundinia kogilamae appear most similar to those of L. tenata in the abdominal coloration. However, the sternapodeme with distinct anterior process, forming an acute angle apically separates L. kogilamae from L. tenata that has an apically rounded sternapodeme without anterior process. Labrundinia kogilamae has been recorded only from its type locality in São Paulo State, Brazil. The adults emerged from the aquatic macrophyte Myriophyllum aquaticum placed in a plastic tray and kept in laboratory. Thus, this is a likely habitat for the unknown immature stages.
