Three new synonyms within the flower chafer genus Goliathopsis Janson, 1881 (Coleoptera: Scarabaeidae: Cetoniinae) from China Author Xu, Hao Author Qiu, Jian-Yue text Zootaxa 2020 2020-06-08 4789 1 91 131 journal article 10.11646/zootaxa.4789.1.3 1175-5326 3884725 CA5C0D09-B499-4077-873F-BF5B55C504B2 Goliathopsis gressitti Ruter, 1978 ( Figs. 10 , 19 , 32–33 , 50–51 , 77–80 , 97–98 , 144–149 , 164 ) Goliathopsis gressitti Ruter, 1978: 287 ( type locality: Pakse, S.

Type material. The number of type specimens was not mentioned in the original publication ( Ruter 1978 ), and the collecting locality and depository of the paratypes are in contradiction with what we have found. Four paratypes were located: the allotype was actually collected from the type locality (Pakse) and preserved in MNHN , it was not from Khong Sedone and deposited in BPBM as claimed in the original publication; the type specimens found in BPBM are three male paratypes . The male holotype ( MNHN , Figs. 144–147 ) is labeled: Paksé (S. Laos ), 15.VII.[19]67 [white label]// Goli- athopsis gressitti m. n. sp., HOLOTYPE , G. RUTER dét. 1976 [white label]// HOLOTYPE [red label]/ MNHN , EC7183 [white label]. The female allotype ( MNHN , Figs. 148–149 ) is labeled: Paksé , Laos , 31.VII.[19]67, [white label] // Goliathopsis gressitti m. n. sp, ALLOTYPE , , G. RUTER det. 1976 [white label]// ALLOTYPE [red la- bel]. Two male paratypes ( BPBM ) are labeled: Laos : Wapikhamthong Prov. , Khong Sedone , 17.VII.1965 // Native Collector , BISHOP MUS. // Goliathopsis gressitti m. n. sp., PARATYPE , G. RUTER dét. 1976 [handwritten on white label] // PARATYPE [red label]. The third paratype bears the same labels except 16.V.1965 . Other material examined ( 29♂♂ , 23♀♀ ).

Body length 12.0–12.5 mm; width 6.5–7.0 mm; Body dark brown to black ( Figs. 77–80 ). Pronotum with a tomentose band along both sides ( Figs. 97–98 ); disc with four small, light yellow, tomentose maculae; disc without tomentose midline; the middle of posterior margin usually with a small, light yellow, tomentose spot ( Figs. 77, 79 , 144 ). Scutellum usually tomentose. Elytron usually with four light brown, tomentose maculae: a large 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, sutural costa and anteapical umbone of elytra ( Figs. 77, 79 ). Disc of elytron with U shaped, setiferous punctures; punctures with few tomentum ( Fig. 10 ); setae long. Pygidium with tomentum and sparse, rounded, setiferous punctures ( Figs. 32–33 ); longitudinal ridge without tomentum in female ( Fig. 33 ). Cephalic horns of male rather long, constricted at base; inner side of base half with tomentum ( Fig. 19 ). Male genitalia small ( Figs. 50–51 ), proximal and distal parts of parameres slightly expanded in apical view, medially constricted, apex rounded; parameres distinctly curved in lateral view, basal piece slightly expanded. This species resembles Goliathopsis duponti , and the differences are provided in the diagnosis section of G. duponti . Distribution. Thailand , Laos .
