Key to known pupal cases of Nearctic species of
Mallophora
1 Maxillary sheath with small median process on each side of labral sheaths; prothoracic spiracle on rugose upraised area; abdominal segment 1 with all or some dorsal spurs expanded, sagittate, broad basally; segments 3–7 usually with median space in transverse row of ventral bristlelike spines (except male
Mallophora bomboides
)........................................................................................................................................2
Maxillary sheath without median process on each side of labral sheaths; prothoracic spiracle almost flush with prothoracic area; dorsal spurs on abdominal segment 1 not basally expanded or sagittate; segments 3–7 without median space in ventral row of bristlelike spines..................................................................3
2 Anterior coxal sheath with suborbital spine at base; wing sheath with 2 median tubercles; abdominal segments 3–7 with ventral transverse row of 7–14 sometimes bifurcate bristlelike spines; abdominal segment 8 with 10 dorsal spurs ..................................................................
Mallophora leschenaulti
Macquart
Anterior coxal sheath without suborbital spine at base; wing sheath with 1 median tubercle; abdominal segments 3–7 with ventral transverse row of 20–36 unforked bristlelike spines; abdominal segment 8 with 2–3 dorsal spurs .......................................................................
Mallophora bomboides
(Wiedemann)
3 Posterior mesothoracic callosity with 1 median spine; abdominal segment 1 with 7–8 spurs in transverse row and 2 shorter median spines on anterior margin; segments 2–4 with dorsal transverse row of 16–20 alternating long, narrow spurs and short, wide, unforked bristlelike spines; segments 3–7 with ventral transverse row of 16–29 bristlelike spines; segment 8 with 4 dorsal spurs and lateral spines on each side... .................................................................................................................
Mallophora fautrix
Osten Sacken
Posterior mesothoracic callosity with 2 subequal spines; abdominal segment 1 with dorsal transverse row of 16 spurs, outermost spine on each side short, 2 median spines threefourths as long as adjacent spines; segments 2–4 with dorsal transverse row of 13–14 bifurcate or unforked spurs and spines of equal size; segments 3–7 with ventral transverse row of 10–14 bristlelike spines; segment 8 with 2 dorsal spurs and 3 lateral spines on each side ....................................................................

(Wiedemann)
