Aaroniella(loving barklice)
Philotarsus(loving barklice)

is a of barklice within the order Psocodea, comprising approximately 150 across eight recognized . The family belongs to the infraorder Philotarsetae and is closely related to Pseudocaeciliidae and Calopsocidae. A revised classification recognizes two : Philotarsinae (tribes Philotarsini and Aaroniellini) and Zelandopsocinae. The family has been extensively studied for its , , and biogeographic patterns, particularly in relation to plate tectonics and historical fragmentation in the southwest Pacific.

Identification

can be distinguished from related Pseudocaeciliidae and Calopsocidae by characters of wing venation and genitalia; a key to is available in systematic treatments. The family is placed in the infraorder Philotarsetae based on morphological synapomorphies. Generic-level identification requires examination of characters including wing shape, areola postica configuration, and male and female genitalic structures.

Distribution

has a broad geographic distribution with strong representation in the southwest Pacific region. Distribution records include North America (Arizona, California), Central America (Guatemala, Mexico), and Pacific landmasses. Biogeographic studies indicate patterns consistent with historical vicariance linked to plate tectonics. The ranges of closely related , such as Aaroniella maculosa and A. eertmoedi, show largely distinct distributions with limited overlap.

Similar Taxa

PseudocaeciliidaeClosely related within Psocomorpha; distinguished by wing venation and genitalic characters.
CalopsocidaeRelated in Psocomorpha; morphological differences in wing structure and genitalia separate the two families.

Taxonomic History

Broadheadia was synonymized with Aaroniella; the Latrobiella was erected. The current classification recognizes two : Philotarsinae (Philotarsini and Aaroniellini) and Zelandopsocinae.

Parthenogenesis

At least one , Aaroniella eertmoedi, has been documented as parthenogenetic with no males observed; this trait has not been confirmed as -wide.
