Explanation of Names
Aphalaroida Crawford, 1914
8 spp. in our area, 9 total(1)
less than 3mm
Forewings short, rhomboidal, often patterned, with pterostigma present. Genae slightly swollen beneath vertex, not conical; Antennae short, between 0.6 and 1.4 times as long as the width of the head. Head, thorax, and forewings often covered with conspicuous glandular hairs. Upon emergence color is pallid throughout, becoming darker and wing pattern developing as the insect matures. The wing maculation is often variable within a single species and thus is not typically sufficient for species-level identification (Hodkinson 2001)

Overview of species based primarily on forewing characters, adapted from on Hodkinson (2001):
Forewing and vertex covered with glandular hairs:
P. spinifera - costal break absent, FW apex broadly rounded, glandular hairs very long
P. rauca - costal break absent, FW apex acute, rhomboidal, glandular hairs short
P. prosopis - costal break present, costal margin straight, vein Rs bent sharply at apex, cell Cu1a short and tall
P. pithecolobia - costal break present, costal margin gently convex, vein Rs straight at apex, cell Cu1a long and less tall
Forewing and vertex appearing glabrous:
P. california, P. inermis, P. acaciae, P. masonici
sw. US & FL to Costa Rica(1)
Acacia & Prosopis (Fabaceae: Mimosoideae)

Heteropsylla spp. also occur on Mimosoid legumes and are found across the same range, though the two genera are easily distinguishable.
