Sphingius scrobiculatus Thorell: Thorell, 1897 View in CoL : 236; description of male. Deeleman-Reinhold, 2001: 489, fig. 839. Sphingius pingtung Tso et al., 2005 View in CoL : Tso et al., 2005: 49, figs. 9–12; description of male. Zhang, Fu & Zhu, 2009: 37, figs 9–12. Syn. nov.

Type material. Holotype: ♂, MYANMAR: Palon: 1885-1889, leg. L. Fea ( MSNG, examined). Original label: Sphingius scrobiculatus Thor. Birmania: Palon. Fea .

New material. THAILAND, Chaiyaphum Province: Tart Tone NP, mixed forest behind NP headquarters, 500 m, sifting decomposed leaves and organic litter, 12 June 2002, P. Dankittipakul, 2♂ ( MNHG, PDC- 589361) .

Remarks. Sphingius scrobiculatus can be distinguished from its congeners by the thicker embolus, and by the very long, RTA curving backwards ( Fig. 1 View FIGURES 1 – 5 ). The description and illustrations of S. pingtung given by Tso et al. (2005) from Taiwan and subsequently by Zhang et al. (2009) from China correspond well with the holotype of S. scrobiculatus originally described from Myanmar ( Fig. 1 View FIGURES 1 – 5 ). Both parties ( Tso et al. 2005; Zhang et al. 2009) distinguished S. pingtung from S. scrobiculatus only on the basis of minor differences in the embolus, the shape of median apophysis and the presence of conductor (which was missing in the original description by Tso et al. 2005). The close genitalic similarities and the discovery of a new material in Thailand intermediate between Myanmar and China indicate that S. scrobiculatus and S. pingtung are best considered synonymous.

Judging from overlapped distribution between S. scrobiculatus (only the male is known) and S. gracilis (only the female is known), it is possible that either these species have rather broad distribution range or they are conspecific. No taxonomic treatment for S. gracilis and S. scrobiculatus is proposed at this stage, pending the discovery of the conspecific male of S. gracilis in China, for which its palpal morphology is presumably similar to or not distinctive from that of S. scrobiculatus .

Distribution. Myanmar, Thailand (new record) and China (Guangxi, Taiwan).
