Protosticta linnaei van Tol, 2008 Protosticta linnaei : van Tol (2008) , pp. 229–231, Figs. 23–26. Type locality: Chu Yang Sin National Park, Dak Lak Province, southern Vietnam .— Yokoi & Souphanthong (2014) , p. 26, Pl. 3, Fig. 15. Notes . P. linnaei was described from Chu Yang Sin National Park, Dak Lak Province of southern Vietnam based on male specimens (van Tol 2008 ). This is a Protosticta species of the P. c u r i o s a group, characterized by a distinct cup-like structure dorsally on the paraprocts, although in P. linnaei this structure is more like a triangular saucer placed on the dorsum of the apex of the paraprocts. Recently Yokoi & Souphanthong (2014) recorded P. linnaei from Lao PDR, but they provided only a rough drawing of its anal appendages (in lateral view) and did not provide a description. For the specific identification of many species of Protosticta a detailed examination of the anal appendages, especially the paraprocts, is required. Therefore, the material from Lao PDR needs further study to ascertain the occurrence of P. linnaei there. The female is still unknown. Distribution . Vietnam (Chu Yang Sin National Park, Dak Lak Province), Lao PDR (Oudomxay Province).
