Type material. Although the original publication of Goliathopsis esquiroli did not indicate the number of type specimens, Pouillaude (1913) explicitly indicated the description based on “Types ♂ et ♀ et quelques exemplaires”, and the entire type series was deposited in Oberthür Collection. A male and a female among a large series of con- specific specimens in MNHN were labeled by Pouillaude as types, but these conspecific specimens all bear the same printed label and the label data conforms to the original publication. Actually, in the case of his new species established on several specimens, Pouillaude only attached his handwritten label to a single specimen for each sex with the term “type” and a citation of the original publication (see Figs. 132, 136 View FIGURES 128–137 ). But the number of the labeled “type” specimen is not always accorded with his statement in the publication. Like so many authors of the period, he only chose a typical individual instead of labeling all type specimens. Consequently, all specimens in MNHN bearing the identical label “ Chine, Kouy-Tchéou, R. P. J. Esquirol, 1913” are treated as syntypes. We also found the same label alongside few specimens of G. esquiroli in RMNH, BMNH, NHMB, IRSNB , and probably in some others. These specimens were believed to belong to the original series and exchanged by Oberthür after the species was named. In order to preserve the stability of zoological nomenclature, the male ( Figs. 128–132 View FIGURES 128–137 ) in MNHN bearing Pouillaude’s label is here designated as lectotype of G. esquiroli : Chine, Kouy-Tchéou, R. P. J. Esquirol , 1913 // G. Es- quiroli, Pllde. Ins. 1913. p421, type ♂ [Pouillaude’s handwriting] // Goliathopsis esquiroli Pouill., G. RUTER dét. 19 [white label]. Forty five paralectotypes (23♂♂, 22♀♀) were examined: 1♀ ( MNHN, Figs. 133–136 View FIGURES 128–137 ), Chine, Kouy-Tchéou, R. P. J. Esquirol, 1913// G. Esquiroli , Pllde. Ins. 1913. p421, type ♀ [ Pouillaude’s handwriting] ; 16♂♂, 14♀♀ ( MNHN) , 1♂, 1♀ ( MNHN, de Lisle collection), Chine, Kouy-Tchéou, R. P. J.

The type locality of Goliathopsis esquiroli was given as Guizhou without exact locality ( Pouillaude 1913), and we believed that Father Joseph Esquirol (1870–1934) perhaps collected them from Wangmo County of southern Guizhou where he worked from 1912 to 1924 ( Moussay & Appavou 2004).

The holotypes of G. camptotropus ( Fig. 72 View FIGURES 66–72 ) and G. polystricus ( Fig. 137 View FIGURES 128–137 ) are presumed lost, and their collecting data are transcribed from the original publication ( Yang 1988) as follows: ♂ (holotype of G. camptotropus ), Luodian County, Guizhou, alt. 450 m, VI.1981, Qian-Ying Meng leg.; ♂ (holotype of G. polystricus ), Wangmo County, Guizhou, alt. 500 m, V.1979, Chen-Jing Yang leg.

Diagnosis. Body length 11.3–12.0 mm; width 5.4–6.0 mm. Body black. Pronotum with four small tomentose spots in disc ( Figs. 62, 64 View FIGURES 62–65 ), the two on same side connected occasionally ( Figs. 69 View FIGURES 66–72 , 128, 133 View FIGURES 128–137 ); the tomentose midline usually absent, at most with several discontinuous maculae ( Figs. 72 View FIGURES 66–72 , 128 View FIGURES 128–137 ). Elytron with many light yellow, tomentose maculae; four maculae usually present on specific positions: a small one on posthumeral area ( Fig. 62 View FIGURES 62–65 ), sometimes enlarged ( Figs. 64 View FIGURES 62–65 , 66, 69 View FIGURES 66–72 ); a small one on the mediodiscal area near sutural costa; a large one on the median portion of lateral declivity, usually expanded towards distal area; a small one on the postdiscal areas near sutural costa, sometimes enlarged ( Fig. 128 View FIGURES 128–137 ). Disc of elytron with drop shaped, setiferous punctures ( Fig. 8 View FIGURES 1–12 ); setae short. Pygidium without tomentum, densely clad with rounded, setiferous punctures ( Figs. 28–29 View FIGURES 22–37 ). Cephalic horns of male slightly constricted at base ( Fig. 16 View FIGURES 13–21 ), sometimes curved backward ( Figs. 67, 70, 72 View FIGURES 66–72 ); inner sides with tomentum. Male genitalia large ( Figs. 40–41 View FIGURES 38–53 ), proximal and distal parts of parameres distinctly expanded in apical view, medially constricted, apex reversed and sharp; parameres almost flat in lateral view, proximal part of basal piece distinctly expanded.

This species resembles Goliathopsis lameyi , but body size smaller, cephalic horns shorter, and elytra with more small tomentose maculae.

Distribution. China: Hunan (new record), Guizhou, Guangxi, Yunnan (new record).

Remarks. The data of Goliathopsis esquiroli in MNHN revealed that this species was not only caught in 1913, Father Joseph Esquirol also collected few individuals in 1911 and 1912. As a French missionary, he worked in Luodian County since 1908, and transferred to Wangmo County in 1912 ( Moussay & Appavou 2004). This fact suggested that the distribution range of G. esquiroli covered southern Guizhou where the types of G. camptotropus and G. polystricus were collected.According to the original descriptions and illustrations ( Yang 1988), the latter two species actually extremely resemble G. esquiroli in appearance and parameres although they have been inappropriately compared with G. gressitti and G. velutinus . Indeed, the diagnostic character of G. camptotropus is the cephalic horns curving backward apically ( Fig. 72 View FIGURES 66–72 ); whereas this is a morphological anomaly that can be observed from a few males in a large series of male specimens of G. esquiroli ( Figs. 67, 70 View FIGURES 66–72 ). Meanwhile, Yang (1988) claimed that G. polystricus differs from G. esquiroli by the position of the tomentous maculae on the dorsal surface ( Fig. 137 View FIGURES 128–137 ); but the size and position of these maculae are not reliable ( Figs. 62, 64 View FIGURES 62–65 , 66, 69 View FIGURES 66–72 , 128, 133 View FIGURES 128–137 ), and the median line on pronotum is sometimes discontinuous ( Fig. 128 View FIGURES 128–137 ), even absent ( Figs. 62 View FIGURES 62–65 , 66 View FIGURES 66–72 ; also see Medvedev 1964; Antoine 1991; Sakai & Nagai 1998). Consequently, the diagnosis characters of both two species are considered in the range of variation of G. esquiroli , and we proposed G. camptotropus and G. polystricus as junior synonyms of G. esquiroli .
