Type species.

Turcopus viscivorus R.S. Anderson, 1994 [original designation].

Gender.

Masculine.

Diagnosis.

R.S. Anderson (1994: 463) separates Turcopus from Coturpus , Cylindrocopturinus , and Eulechriops minutus (LeConte, 1824) by the deep, prominently carinate, cup-like receptacle on the mesoventrite (Fig. 14 ); this has not been seen in the numerous observed specimens of Eulechriops , representing mostly undescribed species, but is difficult to generalize the mesoventrite for all species of such a variable genus. Turcopus is otherwise difficult to distinguish from Eulechriops except by the vestiture pattern (Fig. 92 ) and host association, which are currently unknown in Eulechriops . Turcopus can be further separated from Coturpus by genitalic characters given by R.S. Anderson (1994: 477).

Phylogenetic relationships.

R.S. Anderson (1994: 477) proposed a relationship with the sister taxa of Coturpus + Cylindrocopturinus (those three taxa are the proposed sister to Eulechriops ). The difficulty of separation with Eulechriops suggests a closer relationship with that genus but much work needs to be done in delimiting generic boundaries in this complex of genera.

Host associations.

Turcopus has been collected on Phoradendron on Quercus (R.S. Anderson 1994: 479).

Described species.

One (R.S. Anderson 1994).

Range.

Mexico, Guatemala.
