status

 

Chariodactylus Moser, 1919 View in CoL

Type species

Chariodactylus chacoensis Moser, 1919 View in CoL (designation: Evans 2003: 247).

Diagnosis

Clypeus and frons gradually raised over the lateral area of head ( Fig. 11 A View Fig ); clypeal anteroventral area strongly reduced (similar to Fig. 11 H View Fig ); posterior ocular area exposed ( Fig. 11 A View Fig ), eye large; pronotum as long as wide, with anterior and posterior margins not beaded; prosternum with two anterior sulci (similar to Fig. 11 H View Fig ); protibia with two external teeth and without spur ( Fig. 11 A View Fig ); abdomen with intersegmental membrane VII–VIII exposed.

Remarks

The genera Chariodactylus , Macrodactylus and Manodactylus Moser, 1919 are similar to each other. Chariodactylus ( Fig. 11 A View Fig ) is distinguished as follows (opposition to 1, Macrodactylus ( Fig. 11 C View Fig ); 2, Manodactylus ( Fig. 11 B View Fig )): clypeus broad, trapezoid (1, narrow, trapezoid; 2, as Chariodactylus ); eye large (1, 2, small); pronotum wider than long (1, longer than large; 2, as Chariodactylus ). Future cladistic analysis and a taxonomic review of Macrodactylus including Chariodactylus and Manodactylus are needed to confirm the possible synonymy between these genera.
