description: Copobaenus Fairmaire & Germain, 1863
Fairmaire & Germain (1863: 236), type species Copobaenus nobilis Fairmaire & Germain, 1863 [subsequent designation by Abdullah (1969)].
= Trichananca Blackburn, 1891 syn. nov.
Blackburn (1891: 341), type species Trichananca victoriensis Blackburn (1891) by monotypy].
The synonymy is based on the studied type species of Copobaenus and Trichananca which appear congeneric:
Type material examined, C. nobilis. Lectotype ♂ [designated by Abdullah (1969:335)] BMNH: 28452 [handwritten] // TYPE [printed] // Germain [handwritten] // Chili Chillah [handwritten] // Fry Coll. 1905-100. [printed] // Type H.T. [printed, label circular, red frame] // Copobaenus nobilis Germain Chili (Germain) [handwritten].
Type material examined, T. victoriensis. Holotype ♂ [monotypy] BMNH: T. 3913 A? [handwritten on a card with the specimen] // Type [printed, label circular, red frame] // Trichananca victoriensis, Blackb. [handwritten] // Blackburn coll. 1910-236. [printed].
The two discussed species appear to be rather similar except that in C. nobilis (Fig. 1) the compound eye is smaller and lacks interfacetal setae (the setae are present in T. victoriensis), the postcoxal rests are not present (narrow but well-developed in T. victoriensis), the mesoventral intercoxal process is narrow (distinctly wider, with lateral edges somewhat margined in T. victoriensis), the metathorax is considerably longer (less so in T. victoriensis), the elytra are metallic blue and the ventral pterothorax and abdominal ventrites strongly glossy (slightly glossy in T. victoriensis), the elytral disc confusedly punctate (the punctures arranged into irregular, partially confused longitudinal rows in T. victoriensis), and the elytral epipleuron is present but weakly defined (well-defined in T. victoriensis). The listed features, however, are in my opinion not sufficient enough to treat both genera as valid, and a new generic synonym is introduced.
New combinations are therefore proposed for the species previously attributed to Trichananca: Copobaenus apterus (Lea, 1922) comb. nov., C. bicoloratus (Gemminger in Gemminger & Harold, 1870) comb. nov., C. cheesmanae (Telnov, 2019) comb. nov., C. concolor (King, 1869) comb. nov., C. frenchi (Pic, 1913) comb. nov., fulgidus (Werner & Chandler, 1995) comb. nov., C. hornabrooki (Uhmann, 1995) comb. nov., C. inexpectatus (Telnov & Degiovanni, 2021) comb. nov., C. marziae (Moore & Vidal, 2005) comb. nov., C. micromelas (Lea, 1922) comb. nov., C. neotropicus (Telnov & Degiovanni, 2021) comb. nov., C. nigripennis (Lea, 1917) comb. nov., C. novacaledonicus (Telnov, 2019) comb. nov., C. pisoniae (Lea, 1917) comb. nov., C. poggii (Telnov & Degiovanni, 2021) comb. nov., C. poqui (Guerrero & Diéguez, 2018) comb. nov., C. rugulosus (Uhmann, 2007) comb. nov., C. uniformis (Lea, 1922) comb. nov., C. valenciai (Moore & Vidal, 2005) comb. nov., C. victoriensis (Blackburn, 1891) comb. nov., C. vinctus (Erichson, 1842) comb. nov.
