Type species.

Coturpus arcuatus R.S. Anderson, 1994.

Gender.

Masculine.

Diagnosis.

Within the Eulechriops complex of genera, Coturpus can be identified by lacking a striolate profemoral patch (as in Copturomimus ), lacking a very prominent receptacle on the mesoventrite (as in Turcopus ), lacking the premucro-like inner flange at the tibial apex (as in Cylindrocopturinus ), and can be differentiated from the observed species of Eulechriops by bearing elongate setae on the ventral surface of strongly arcuate hind legs at least in the males and by lacking a procoxal mesal tooth (though with the vast numbers of undescribed Eulechriops it is difficult to rule out the absence of this character from that genus).

Notes.

Females are unknown, and R.S. Anderson (1994: 482) suspects the modified hind legs to be found only in males as similar modification to the hind legs is known only in male Cylindrocopturinus .

Phylogenetic relationships.

R.S. Anderson (1994: 462) proposed a relationship to Cylindrocopturinus based on the presence of elongate setae on the ventral surface of the hind legs in males. This genus is difficult to separate from large and variable Eulechriops . Coturpus can be further separated from Turcopus and Cylindrocopturinus by genitalic characters given by R.S. Anderson (1994).

Host associations.

The genus has been collected on mistletoe, Phoradendron Nutt. ( Santalaceae ) on Quercus (R.S. Anderson 1994: 484).

Described species.

One (R.S. Anderson 1994).

Range.

Mexico.
