Workers
Workers of aureocuprea, caudapinniger, cilium, and clarivida are unknown.
1. Only a single hair present lateral to (outside of) the longest hair on the anterior margin of the clypeus in full-face view (Fig 7). Denticle present on base of subapical (second from apex) tooth (Fig 7) with no gap present between basal dentition and apical teeth............................................................................................... 2
-. Two or more hairs present lateral to the longest hair on the anterior margin of the clypeus in full-face view (Fig 8). Denticle absent on base of subapical (second form apex) tooth (Fig 8) with a gap present between basal dentition and apical teeth... 3
2. Propodeal spiracle large, visible in dorsal view at posterior lateral corner of propodeum (Fig 9). In lateral view, petiolar spiracle large, its horizontal diameter as long as the distance between the spiracle and anterior margin of petiolar node... bressleri
-. Propodeal spiracle small, not visible in dorsal view (Fig 10), located on lateral propodeum (Fig 77). In lateral view, petiolar spiracle small, its horizontal diameter distinctly shorter than the distance between the spiracle and anterior margin of petiolar node............................................................................................ goblin
3. Posterior margin of head flat. In posterior view, fifth (apical) tarsomere distinctly wider compared to fourth (Fig 11). Ventral margin of head in lateral view distinctly convex...................................................... caputleae
-. Posterior margin of head concave. Fifth (apical) tarsomere in posterior view almost the same width as fourth (Fig 12). Ventral margin of head in lateral view relatively flat.......................................................... venatrix
Males
1. Parameres broadly overlapping dorsally, almost along the whole length of basimere (Fig 13). Posterodorsal portion of paramere with a distinct, flattened, needle-like projection, and with a deep notch separating the projection and paramere (Fig 13).......................................................................................... bressleri
-. Parameres not or sometimes narrowly overlapping dorsally on small part of basimere (Fig 14). Posterodorsal portion of paramere without needle-like projection, or without a deep notch separating the projection and paramere (Fig 14)......... 2
2. Posterior portion of paramere narrow, forming a blunt, needle-like projection (Fig 15). Large species (WL> 2.1mm).... cassis
-. Posterior portion of paramere wide, not forming a needle-like projection (Fig 16). Small to medium species (WL<2.1mm).. 3
3. Notaulus distinctly impressed on mesoscutum (Fig 17). Body color usually black to blackish brown, rarely brighter. Small species (WL 0.79–1.28mm)........................................................................ goblin
-. Notaulus not impressed on mesoscutum (Fig 18). Body color usually brown to yellow, sometimes darker. Medium to small species (WL 1.03–2.03mm)............................................................................ 4
4. Paramere with a broad, distinct lobe posterodorsally (Fig 19). Subpetiolar process small, but distinct. Palpal formula 2,2.............................................................................................. caudapinniger
-. Paramere without distinct lobe posterodorsally (Fig 20). Subpetiolar process distinct or indistinct. Palpal formula usually 3,3 rarely 2,3............................................................................................ 5
5. Lateral ocellus relatively small and distant from eye; distance between them more than 1.5× maximum diameter of lateral ocellus (Fig 21). Subpetiolar process developed, with few hairs. Body color brown........................... caputleae
-. Lateral ocellus relatively large and close to eye; distance between them less than 1.5× maximum diameter of lateral ocellus (Fig 22). Subpetiolar process variable, but usually poorly developed and often without hairs. Body color brown to yellow.. 6
6. Distance between lateral ocelli about same length or less than maximum diameter of mid ocellus. Distance between lateral ocellus and eye 0.5× or less than maximum diameter of lateral ocellus (Fig 23). Hairs on compound eye more than 0.33× of horizontal diameter of mid ocellus. Anterior face of mesofemur with only subdecumbent short hairs (Fig 25)...... clarivida
-. Either distance between lateral ocellus distinctly longer than maximum diameter of mid ocellus, or distance between lateral ocellus and eye distinctly longer than 0.5× length of maximum diameter of lateral ocellus (Fig 24), or hairs on compound eye distinctly shorter than 0.33× length of horizontal diameter of mid ocellus, or anterior face of mesofemur with short and dense long hairs (Fig 26)..................................................................................... 7
7. Hairs on compound eye longer than 0.5× length of horizontal diameter of mid ocellus (Fig 27). Subpetiolar process developed............................................................................................... cilium
-. Hairs on compound eye shorter than 0.25× length of horizontal diameter of mid ocellus (Fig 28). Subpetiolar process not developed........................................................................................... 8
8. Body color uniform dark brown (Fig 37). Parapsidal line clearly impressed, usually highlighted with darker pigment. venatrix
-. Body bicolored, head brown and the other body parts yellow (Fig 29). Parapsidal line usually unclear, sometimes weakly impressed, without pigmentation............................................................... aureocuprea
