Type species.

Zygopsella ruficauda Champion, 1906 [by original designation].

Gender.

Feminine.

Diagnosis.

Zygopsella is similar in appearance to Archocopturus and some species of Macrocopturus , Hoplocopturus , and Copturomimus with blue-green pronotal scales, but of those genera is similar only to Archocopturus with the subequal first two articles of the funiculus and deep pronotal punctures. From Archocopturus , Zygopsella can be separated by the more widely separated eyes (Fig. 54 ), the more sharply acuminate lower margin and more strongly inflexed lower lateral margin of the eyes, the more strongly arcuate lateral margins of the pronotum (Fig. 103b ), the ventrally toothed profemora, the ventrally emarginate tibiae to receive the femoral tooth, and the flattened caudal prominences of the elytra (Fig. 103b ).

Phylogenetic relationships.

Suggested by Champion (1906b: 42) to be closely related to Archocopturus . The combination of ascending abdominal ventrites, concealed pygidium, unmodified mesoventrite, carinate and ventrally toothed metafemora and short second funicular article of the antenna is shared only with Archocopturus , Phileas , and Larides (the latter only with a faint carina in the distal half of the femora). Also similar to many Cylindrocopturus with the elytral processes and relatively widely sepa rated eyes. Zygopsella has a similar eye shape to Helleriella that is strongly laterally inflexed and sharply ventrally acuminate.

Host associations.

Unknown.

Described species.

Two, including one species transferred from Archocopturus by Hespenheide (2005).

Range.

Mexico ( Hespenheide 2005: 683), Guatemala, Costa Rica ( Hespenheide 2005: 682), Panama ( Hespenheide 2005: 683), Guadeloupe ( Hespenheide 2005: 683).
