Type material. The species was described based on a large series of specimens (147 males and 148 females) collect- ed from Sila Phet , Nan; Lampang; Mae Tha , Lamphun; Mae Taeng , Chiang Mai; and Wang Muea. Only five type specimens were examined, others should be preserved in several private collections as stated in the original publication ( Antoine 1991). Male holotype ( MNHN, Figs. 122–125 ) is labeled: N. Thailand, Sila Phet Nan, 12. VIII. [19]89, Ferrero leg. [white label] // HOLOTYPE Goliathopsis duponti ♂, Ph.

Diagnosis. Body length 11.5–13.0 mm; width 6.0–6.5 mm. Body black. Pronotum with tomentum on lateral portion ( Fig. 58 ); disc usually without tomentose midline (few individuals with an indistinct, light yellow midline); the middle of posterior margin usually with a small, light yellow, tomentose spot. Elytron usually with four light yellow, tomentose maculae: a small one on posthumeral area; a small one on the mediodiscal area near sutural costa; a large one on the median portion of lateral declivity; a large one on the postdiscal areas near sutural costa. Few other small tomentose maculae scattered on disc near scutellum and anteapical umbone. Disc of elytron with U shaped, setiferous punctures ( Fig. 7 ); setae long. Pygidium with rounded, setiferous punctures ( Figs. 26–27 ); longitudinal ridge without tomentum in female ( Fig. 27 ). Cephalic horns of male not constricted at base, without tomentum ( Fig. 15 ). Male genitalia large ( Figs. 44–45 ), proximal and distal parts of parameres distinctly expanded in apical view, medially constricted, apex rounded; parameres slightly curved in lateral view, proximal part of basal piece expanded.

This species is similar to Goliathopsis gressitti , but can be distinguished from the latter by punctures on elytral disc glabrous ( Fig. 7 ; with tomentum in G. gressitti , Fig. 10 ); elytra with less tomentose maculae; cephalic horns shorter, more expanded at apex, and not constricted at base ( Fig. 15 ; slender and constricted at base in G. gressitti , Fig. 19 ); shape of parameres different.

Distribution. China: Yunnan?; Myanmar, Thailand.

Remarks. Almost all records of Goliathopsis duponti are from northern Thailand ( Antoine 1991; Sakai & Ikeda 1996; Sakai & Nagai 1998), and only one paratype is from western Myanmar. However, a pair of specimens were presented by Li et al. (2013) from Mount Gaoligongshan of Yunnan where is far from its known distribution. Thus, this record needs to be confirmed in the furture investigation.

FIGURE 164. Known distribution of Goliathopsis Janson, 1881 species. Syncretic markers indicate identical or very close localities; type localities of the known species are marked, that of G. despectus (Westwood, 1873), G. cervus Janson, 1881, and G. esquiroli Pouillaude, 1913 are missing because the precise type localities are unknown.
