Gaster: pedunculate; clavate (widest at T4)

Scutum high, rounded, arched forward

First gastral segment: pedunculate; nodose; without dorsoposterior spine (cf Notocrabro)

Forewing venation: single submarginal cell; recurrent vein meets submarginal cell near middle (ratio of basal to apical segments ~ 5:4)

Prepectus: area rounded (although anterior & lateral planes distinct); epicnemial carina entirely absent

Verticaulus absent

Head shape: subquadrate (in dorsal view)
Ocelli arrangement: subequilateral triangle

Note PO < OO, potentially useful in species identification.

Orbital fovea: distinct
Scapal basin: without dorsal carina
Female: 10 flagellar segments

Scapal basin: without dorsal carina

Note the clypeus shape … potentially helpful in species identification.

Pygidial plate: present

Pygidial plate: apparently impunctate; shiny.

Note the concave apical half and the domed mediobasal region, potentially helpful in species identification.

Size ~ 5mm
Gaster: pedunculate; clavate (widest at T4)

Gaster: clavate (widest at T4)

Scutum higher than pronotal collar, rounded anteriorly

Scutum higher than pronotal collar, rounded anteriorly

First gastral segment: pedunculate; weakly nodose when viewed laterally

Forewing venation: single submarginal cell; recurrent vein meets submarginal cell beyond middle (ratio of basal to apical segments ~ 5:3)

Prepectus: area rounded; epicnemial carina entirely absent

Prepectus: area rounded; epicnemial carina entirely absent
Verticaulus: absent

Head shape: quadrate
Ocelli arrangement: equilateral triangle

Note large VOL (distance from posterior ocelli to rear of vertex), potentially relevant to species identification.

Note: pronotal corner shape … may be useful for species level identification

Orbital fovea: small, indistinct
Scapal basin: without dorsal carina
Female: 10 flagellar segments

Note clypeus shape … potentially helpful for species identification

Note clypeus shape and mandible width shape plus colour … potentially useful in species identification

Note mandible shape … potentially useful in species identification

Pygidial plate: impunctate

Size ~5mm (perhaps slightly larger)
Gaster: pedunculate; clavate (widest at T4)

Gaster: pedunculate (first segment weakly nodose when viewed laterally); clavate (widest at T4)

Head shape: quadrate
Gaster: pedunculate

Note: pronotal corners prominent … may be helpful for species level identification

Forewing venation: single submarginal cell; recurrent vein meets submarginal cell beyond middle (ratio of basal to apical segments ~3:2)

Scutum higher than pronotal collar, rounded anteriorly

Prepectus: area rounded; epicnemial carina entirely absent

Verticaulus: absent

Head shape: quadrate
Ocelli arrangement: equilateral triangle

Note large VOL (distance from posterior ocelli to rear of vertex), potentially relevant to species identification.

Note clypeus shape … potentially helpful for species identification

Note clypeus & mandible shape … potentially useful in species identification

Note clypeus & mandible shape … potentially useful in species identification

Note mandible shape … potentially useful in species identification

Pygidial plate: impunctate

Note: the pale structure is probably a parasite (stylops?)
