Body length 11.5–12.5 mm; width 5.8–6.7 mm. Dorsal surface and pygidium clad with light yellow and brown tomentum ( Figs. 73, 75 ). Pronotum with four indistinct, small, tomentose maculae ( Fig. 75 ); disc darker, lateral portion light yellow or brown ( Figs. 73, 75 , 95–96 , 138, 140, 142 ); midline on pronotum and scutellum yellow, distinct. Elytron usually with 4 light brown maculae: a small one on posthumeral area; a small one on the mediodiscal area near sutural costa; a small one on the median portion of lateral declivity, sometimes enlarged ( Fig. 96 ); a large one on the postdiscal areas near sutural costa. Few other small tomentose maculae scattered on declivity of elytra ( Fig. 140 ). Disc of elytron with U- and drop shaped, setiferous punctures ( Fig. 9 ); setae very long. Pygidium with rounded punctures ( Figs. 30–31 ); longitudinal ridge without tomentum in few individuals ( Fig. 31 ). Cephalic horns of male slender, not constricted at base; without tomentum ( Fig. 17 ), sometimes with few tomentum on inner surfaces and proximal portion ( Fig. 18 ). Male genitalia small ( Figs. 46–47 ), proximal and distal parts of parameres expanded in apical view, medially constricted, outer line of distal part obtusely angled, apex sharp; parameres almost flat in lateral view, basal piece expanded. FIGURES 73–76. Habitus of Goliathopsis ferreroi Antoine, 1991 (dorsal and ventral view). 73–74, male; 75–76, female. FIGURES 77–80. Habitus of Goliathopsis gressitti Ruter, 1978 (dorsal and ventral view). 77–78, male; 79–80, female. This species resembles Goliathopsis despectus , and the differences are already provided in the diagnosis section of G. despectus . Goliathopsis ferreroi is also similar to G. velutinus , but can be differentiated by inner surface of cephalic horns glabrous, at most tomentose in proximal portion ( Figs. 17–18 ; totally tomentose in G. velutinus , Fig. 21 ). Besides, the shape of parameres of these three species is distinctly different as shown in Figs. 42, 46, 48 . Distribution. Thailand , Laos .
