flagellum: the third and largest part of the antenna, divided into a large first flagellomere and a hair-like arista (made up of barely distinguishable separate flagellomeres)
femur: third leg segment (the first of the two long parts of the leg); located between the trochanter and the tibia.
geniculate: elbowed.
labellum: the terminal part of the proboscis (derived from the lower lip, or labium).

seta: bristle.
setae: multiple bristles.
setulae: small setae.
subquadrate: almost square in shape.
tarsus: the distal (last) leg segment, subdivided into 5 tarsomeres.
tergites: dorsal plates of the abdominal segments.
tibia: fourth leg segment, located between the femur and the tarsomeres.
