Platynectes mazzoldii Šťastný, 2003

( Figs 4D , 12A )

Platynectes mazzoldii Šťastný, 2003: 240 (orig. descr.).

Type locality. “ Thailand, Phu Hin Rongkla National Park , Huai Khamunoi ” .

Type material. Holotype ♂, deposited in NHMW.

Material examined. CHINA: Yunnan: 1 ♀, “ China: Yünnan, Xishuangbanna ca. 15 km NW Menglun 5.11.1999, ca. 700–800 m leg. Jäch, et al. (CWBS 354)” ( NHMW) .

Notes. Habitus is given in Fig. 4D .

Collection details. Found in primary forest streams and pools near waterfalls at altitudes ranging from 700 to 1250 m a.s.l. ( Šťastný 2003).

Distribution. Southern China (Yunnan, Xishuangbanna) ( Fig. 12A ).

Notes. This species was reported from China based on only a single female specimen from Xishuangbanna, Yunnan (CWBS 354) by Šťastný (2003). This female was studied in great detail by one of us (J. Šťastný) and because it was identical in all characters with specimens from the type series it was identified as P. mazzoldii . It was not included in the type series ( Šťastný 2003) because it was found about 500 km from the type locality of P. mazzoldii . There is currently a gap in the known distribution, but it is likely that it may occur from Thailand to southern China. The occurrence and distribution of this species in China need to be confirmed by further records.
