Coscinoptera Lacordaire 1848: 511; Chapuis 1874: 139; Jacoby 1880: 31; Horn 1892: 12-13; Jacoby and Clavareau 1906: 62-63; Clavareau 1913: 77; Leng 1920: 288; Guérin 1943: 32-33; Blackwelder 1946: 637; Monrós 1951a: 1150-1151; Monrós 1953a: 114-115; Moldenke 1970: 41, 1981: 89.
Type species.
Coscinoptera desmiphora Lacordaire, 1848, designated by Monrós (1953a: 114).
Diagnosis.
This genus can be separated from Euryscopa by the lack of bilobed lacinia and the elytra with confused punctation, in some cases exceedingly coarsely and deeply punctate. Other useful diagnostic characters are: head moderately prominent, covered with dense fine punctation and silky pubescence; male head as long as wide; eyes round and salient; prothorax transverse, pronotal disc as high as long; scutellum often coarsely punctate and always with dense white pubescent; elytra either metallic unicolored and glabrous or black; ventrites usually covered with exceedingly dense white pubescence; female anal pit normally small and only moderately depressed.
Distribution.
USA to Argentina.
Remarks.
As for other groups within Clytrini , it is in need of modern taxonomic revision. Several species groups have been proposed, but their monophyly has not yet been tested. Monrós (1953a), split this genus into two informal species groups, mainly based on sexual dimorphism evident in male heads. Moldenke (1970) proposed six informal species groups. Subsequently, Moldenke (1981) preserved only three of his earlier groups and transferred some species to two new genera ( Coleorozena and Coleothorpa ). More recently, Agrain and Roig-Juñent (2011), recovered a monophyletic clade (sister to Megalostomis ), containing the type species of Coscinoptera , Coleorozena , and Coleothorpa . This clade is supported by two synapomorphies: male head as long as wide, and pronotal disc as high as long. Consequently, the latter two genera were synonymized with Coscinoptera . Some North American species are found in the nests of ant genera Camponotus Mayr and Formica Linnaeus. Moldenke (1981) divided this genus into three species groups and he indicated three species to be present in Argentina: Coscinoptera euryscopoides Monrós, and Coscinoptera terebellum Lacordaire within group II; and Coscinoptera tibialis Harold within group III.
