Diagnosis
Evaniscus marginatus is recognized by the combination of the following character states: subantennal carina length: extending dorsally of medial margin of lower face; pronotal lobe carina presence: absent; mesofemoral depression sculpture: foveate; mesofemoral depression pilosity presence: present.
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. Mandible color vs clypeus color: mandible color different than clypeus color; mandible color same as clypeus color. Subantennal carina length: extending dorsally of medial margin of lower face. Preorbital carina length: extending dorsally to the ventral margin of the anterior ocellus. 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: 1.5× 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 wider than long (length of flagellomere < width of flagellomere). Shape of occiput: as high as wide.
Mesosoma . Mesosoma length: 2.75–2.75 mm (n=4). Antero-dorsal region of mesosoma color: black. Postero-ventral region of mesosoma color: black. Median notch of transverse pronotal carina presence: present. Transverse pronotal carina length: long, extending postero-laterally of epomia. Pronotal collar sculpture: scrobiculate and foveate. Patch that is part of dorsal region of lateral pronotal area texture: smooth. Pronotal lobe carina presence: absent. Mesonotum color: 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: absent. Distance between depressions vs. diameter of depressions on internotaular area: greater than the diameter of one depression. Mesofemoral depression sculpture: foveate. Mesofemoral depression pilosity presence: present. 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.
Legs . Fore leg color: yellow; red. Mid leg color: yellow; red. Hind leg color: black. Metafemur length vs. metatibia length: metafemur equal to or shorter than metatibia. Metabasitarsus length vs metatibia length: metabasitarsus 1.4× to 1.6× 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.
