Gergithus multipunctatus Che et al. 2007: 621 [described], figs 42–50 [head, thorax, tegmen, hind wing and male genitalia illustrated].

Gergithus multipunctatus – Meng & Wang 2012: 4 [keyed], 8 [compared with G. nonopunctatus Meng & Wang, 2012 ] — Chen et al. 2014: 4 [listed from China], 190 [distribution, material examined – see note infra].

non Gergithus multipunctatus – Chen et al. 2014: (erroneous: based on wrong identification of an undescribed species) 50 [keyed], 55 [described], 56 [habitus, details and male genitalia illustrated], 190 [material examined (see note infra)] — Guo & Chen 2015: (erroneous: based on wrong identification of an undescribed species) 430 [material examined], 431 [colour and ratios], 432–433 [male genitalia], figs 9–10, 17, 23, 29, 35 [habitus, frons and male genitalia illustrated].

Note

The illustrations of the species by Chen et al. (2014) and Guo & Chen (2015) show strong discrepancies when comparing with the original description and accompanying illustrations provided by Che et al. (2007). The specimen illustrated in the two first papers shows a yellow vertex (instead of brown) and frons without yellow spot near dorsal margin. The illustrations of the male genitalia, despite their poor quality in the two first works, also show strong differences, especially obvious in the shape of the ventrolateral lobe of the phallobase which is much larger in Che et al. (2007).

The list of material examined by Chen et al. (2014) mentions only one male available for genitalia examination. It originates from Hainan, Wuzhishan, rather far from Jianfeng Mountain, the only surely recorded location for G. (Maculergithus) multipunctatus to date.

The concept of G. (Maculergithus) multipunctatus in Chen et al. (2014) and Guo & Chen (2015) should not be taken as indicative of the species.

Diagnosis

The species can be recognized by the following combination of characters: (1) frons with a round yellow spot below dorsal margin, not reaching the latter; (2) vertex brown; (3) 4 yellow spots on tegmina along sutural margin; (4) tegmina with 10 yellow spots in total.

Identification can be confirmed by the male genitalia characters illustrated in Che et al. (2007: figs 46– 49).

Distribution

Known from China, Hainan: Jianfeng Mountain ( Che et al. 2007) (see map Fig. 1 ).

Remark

The mention of the species in Hainan: Wuzhishan by Chen et al. (2014) is based on the misidentification of a yet undescribed species and hence erroneous.
