Diagnosis.

Evaniscus rufithorax is the most commonly collected species of in the genus. This species differs from other Evansicus by a combination of the following character states: pronotal lobe carina presence: present; subantennal carina length: extending ventrally of medial margin of lower face.

Description.

Head. Head color: dorsal half of upper face and vertex color black; ventral half of upper face and lower face color red or yellow; orange. Mandible color vs clypeus color: mandible color same as clypeus color. Subantennal carina length: extending ventrally of medial margin of lower face. Preorbital carina length: extending dorsally to ventral margin of the antennal foramen. Upper face sculpture: foveate. Malar space length vs. half compound eye height (male): shorter than half compound eye height. Ocellar ocular line length vs. lateral ocellus diameter: shorter than lateral ocellus diameter. Posterior ocellar length vs. lateral ocellus diameter: 1.5x as long as the diameter of the lateral ocellus. Ventral region of occipital carina curvature in lateral view: straight. Ventral region of the postoccipital carina shape: not raised. Radicle color: yellow; orange. Scape color: yellow; orange. Scape length vs compound eye height: scape shorter than half compound eye height. Female flagellomere 1-8 shape: distinctly longer than wide (length of flagellomere> width of flagellomere). Shape of occiput: as high as wide.

Mesosoma. Mesosoma length: 2.25-2.85 mm (n=29). Antero-dorsal region of mesosoma color: red. Postero-ventral region of mesosoma color: black; red. Median notch of transverse pronotal carina presence: present. Transverse pronotal carina length: long, extending postero-laterally of epomia. Pronotal collar sculpture: foveate. Patch that is part of dorsal region of lateral pronotal area texture: smooth. Pronotal lobe carina presence: present. Mesonotum color: red; black. Mesoscutum shape: as long as wide (length of mesoscutum> width of mesoscutum). Antero-admedian line length vs. lateral ocellus diameter: equal to lateral ocellus diameter. Parapsidal signum conspicuousness: inconspicuous. Foveae on notaulus presence: present. Distance between depressions vs. diameter of depressions on internotaular area: greater than the diameter of one depression. Mesofemoral depression sculpture: smooth. Mesofemoral depression pilosity presence: absent. Ventral area of the mesopectus sculpture: foveate. Medial region of transmetapectal carina presence: absent. Area dorsal of transmetapectal carina sculpture: smooth. Posterior propodeal projection shape in lateral view: not raised. Posterior region of plica presence: absent. Dorsal area of the metapectal-propodeal complex sculpture: foveate. Posterior margin of the metapectal-propodeal complex ventrally of the propodeal foramen curvature in lateral view: curved. Mesosoma color: black posteroventrally, red anterodorsally.

Legs. Fore leg color: yellow; red. Mid leg color: yellow; red. Hind leg color: red-black. Metafemur length vs. metatibia length: metafemur equal to or shorter than metatibia. Metabasitarsus length vs metatibia length: metabasitarsus 1.2 × to 1.4 × as short as metatibia.

Wings. Fore wing vein color: black. Setae on proximal region of fore wing color: black.

Metasoma. Metasoma color: black. Dorsal region of petiole sculpture: foveate.

Comments.

A lectotype was designated because syntypes were from specimens with different localities and one syntype varies in color; the male specimen chosen as lectotype from Peru is in very good condition and fits the description well. The male paralectotype from Bolivia that is at ZMPA varies in color (only) from the other type specimens and all known other material; the antero-dorsal region of mesosoma color is red in all Evaniscus rufithorax specimens, but is black in this type specimen.
