Type species.

Copturus regalis Boheman, 1845 [by monotypy].

Gender.

Masculine.

Diagnosis.

Archocopturus can be separated from the other zygopines that have a concealed pygidium and a second funicular article that is subequal to the first by the following combination of characters: the eyes are separated at the top by a small lanceolate space (Fig. 48 ; also in other genera - e.g. many species of Macrocopturus ), the vertex of head has a triangular, transversely striolate region (visible in Figs 48 and 94b for Archocopturus but most noticeable in Fig. 95b for Cylindrocopturus ; also seen in some species of other genera, e.g. Zygops , Cylindrocopturus ) the pronotum has deep, close punctures, the profemora are unarmed, and the hind femora are carinate and ventrally toothed and do not extend much beyond the abdominal apex. Additionally, all known species of Archocopturus have blue-green scales on the pronotum, suggesting mimicry of the dolichopodid genus Medetera ( Hespenheide 2005). While this coloration is found in several other genera of Conoderinae , the only other zygopine with it is Zygopsella , which Archocopturus can be easily separated from by the lack of a ventral profemoral tooth and the more approximate eyes. The mesoventrite is flat in most species but posteromedially depressed in A. championi .

Phylogenetic relationships.

Champion (1906b: 42) suggests a relationship with Zygopsella . The two genera have in common the deep punctures of the pronotum (also in Arachnomorpha ) and blue-green scales.

Host associations.

The South American Archocopturus regalis (Boheman, 1845) has been reared from branches of Lecythidaceae in Peru ( Fassbender 2013).

Described species.

Four species are known from the focal region, which includes all four species described by Hespenheide (2005). One additional species is known from South America ( Wibmer and O’Brien 1986: 270, Hespenheide 2005: 671).

Range.

Mexico, Belize, Guatemala, Honduras ( Hespenheide 2005), Nicaragua, Costa Rica, Panama; South America.
