Figs 48–53

Material examined. 3 Males, 6 females (MHNG), Borneo, EAST MALAYSIA , Sabah , West Coast Residency, Kinabalu N.P., Poring Hot Springs , 500 m a.s.l., edge of relatively dry Dipterocarpaceae forest, sifting rotten wood, mushrooms and dead leaves under trees; 6.V.1987; D. Burckhardt & I. Löbl leg. [14a] . 3 males ( MHNG), Poring Hot Springs , 550–600 m a.s.l., Dipterocarpaceae forest, sifting rotten wood, leaves, especially bamboo; 9.V.1987; D. Burckhardt & I. Löbl leg. [18a].

Type material examined. Male holotype and female paratype of Pronasoona sylvatica Millidge, 1995 ( MHNG), from Kinabalu N.P., Poring Hot Springs.

Remarks. The new material of P. sylvatica is all from the type locality.

Taxonomic remarks. Millidge (1995), referring to the close relationship of the genera Pronasoona and Nasoona , pointed out the similarity of their habitus characters (see Figs 48–50, 53 ). At the same time, he mentioned differences in the palp structure of these genera, but failed to specify any. Nevertheless, the differences are quite significant: the embolic division in Pronasoona , in contrast to Nasoona , has no convector, but has a large radix with a relatively short tailpiece (see Figs 51, 52 ). In addition, the embolic division in Pronasoona , in contrast to Nasoona , shows a hypertrophied and complex anterior radical apophysis that bears several strongly sclerotized or membranous outgrowths.

Distribution. Borneo, East Malaysia ( Millidge 1995).
