Key to Tribes of Australian Neopasiphaeinae

1. Forewing marginal cell bent away from anterior wing margin at apex, sometimes only slightly so; facial fovea broad or absent; mandible of female usually four or more times as long as basal width, bidentate, lower tooth much longer than upper (upper tooth bilobed, giving tridentate appearance, in Anthoglossini ); pygidial plate of female with lateral margins not strongly concave, apex neither slender nor parallel-sided (except a few rare exceptions) ...................... 2

—. Forewing marginal cell with apex on anterior wing margin; facial fovea linear or nearly so (often very short or absent in male); mandible of female two to three times as long as basal width, ending in three equally conspicuous teeth; pygidial plate of female with lateral margins concave, apex quite slender and parallel-sided [ Callomelita Smith ] ...................................... Callomelitini

2. Pterostigma small, parallel-sided, truncate (sometimes obliquely so) at base of r-rs or rarely shortly beyond that point, not or scarcely tapering to apex within marginal cell; marginal cell on leading edge of wing 2.75–5.0× as long as pterostigma ................................................................................................................. 3

—. Pterostigma usually larger and usually not parallel-sided, apex usually tapering to a point on leading edge of marginal cell, r-rs thus arising near midlength of pterostigma; marginal cell on leading edge of wing 1.3–2.5× as long as pterostigma .................................................................................. Neopasiphaeini

3. Inner metatibial spur of female finely serrate or pectinate with slender branches of approximately uniform length arising from a rachis that tapers rather uniformly toward apex; metabasitibial plate fully defined, in some females visible without removal of setae, rounded or blunt apically; mandible slender near base, expanded apically, female with upper apical tooth bidentate in unworn mandibles, mandibular apex of female thus tridentate; compound eyes parallel or converging below [ Anthoglossa Smith ] ................................... Anthoglossini

—. Inner metatibial spur of female densely pectinate and almost palmate, with long branches, rachis thick near base and narrowing in region where most branches arise; metabasitibial plate of female defined only along posterior margin, or, at least apex not defined, plate never visible without removal of setae; metabasitibial plate of male variable, acutely pointed if defined; mandible approximately parallel-sided, apex bidentate; compound eyes often diverging below [ Trichocolletes Cockerell ] ........................................................ Trichocolletini
