Remarks: Liu (1993) described Lamelligomphus jiuquensis from a single female collected from Xingcun, Fujian ( Figs. 15l–n ). Liu (1993) considered jiuquensis to be similar to L. formosanus but differed in four points: (i) prothorax black, with yellow stripes, (ii) colour pattern of synthorax with 2 nd and 3rd lateral yellow stripes broad and complete, but antehumeral stripe broken in the middle, (iii) 7th abdominal sternum not constricted subapically, (iv) a pair of occipital horns closing or parallel to each other. Lui's characters used to distinguish L. jiuquensis from L. formosanus also apply to female L. formosanus ! Four male and one female L. formosanus specimens collected from Shimentai have an interrupted yellow stripe across the metepisternum and one male and four females are marked with an uniterrupted yellow stripe and although one male and one female possessed uninterrupted antehumerals stripes the remainder were interrupted ( Fig. 15b ). Three of the Shimentai females are marked with a pair of small yellow spots on the central dorsum of the prothorax, whereas the prothorax of the remaining two females and all five males are entirely black. There is slight variation in the structure of the occipital horns; one female features almost parallel sided horns ( Fig. 15i ). This same female from Nanling also featured an entirely black postclypeus and a slightly shallower groove dividing the yellow spots on the postfrons than Shimentai females. It is apparent that the differences described by Liu (1993) for the type female L. jiuquensis are merely phenotypic variation in colouration. There are no structural differences between L. jiuquensis ( Figs. 15j–l ) and L. formosanus ( Figs. 15a–i ). The undulating occiput, shape of the occipital horns and deep central dorsal groove on the top of the frons are identical. The two species are here considered synonymous. The record of Lamelligomphus formosanus from Hainan ( Hua 2000 ) requires confirmation. Distribution: China ( Fujian , Guangdong , Guangxi , Guizhou , Hainan [?] and Taiwan) .
