Pseudopoda columnacea Zhang, Jäger & Liu , spec. nov. Figs 60–61 , Map 2

Type material. THAILAND, Chiang Mai Province: Holotype male from Doi Inthanon National Park , sweeping in lower evergreen forest [18.59°N, 98.48°E], 1680 m, 20 August 2006, P. Dankittipakul leg. ( MHNG, THI0004 ) . Paratype: 1 male, with same data as for holotype ( MHNG, THI0005 ) .

Etymology. The specific name is derived from the Latin adjective columnaceus, - a, - um, meaning

“columnar”, referring to the shape of the tegular apophysis; adjective.

Diagnosis. The male of P. columnacea Zhang, Jäger & Liu , spec. nov. can be distinguished from those of other Pseudopoda species by the columnar tegular apophysis in ventral view.
