Homilopsocidea

Wings and genitalia of Sabulopsocus tractuosus, from Schmidt & New (2004).

Belongs within: Psocomorpha.
Contains: Elipsocidae, Lachesilloidea, Pseudocaecilioidea, Peripsocoidea.

The Homilopsocidea are a clade of bark-lice supported by two synapomorphies: the presence of an egg-guide exteneding from the dorsodistal margin of the female subgenital plate, and dorsal swelling of the dorsal valve of the gonapophyses (Yoshizawa 2002).

Characters (from Yoshizawa 2002): Head usually with rounded vertex except sharply pointed in Calopsocidae; postclypeus usually well bulged; epistomal suture with or without well-developed internal ridge; anteclypeus variable; male eyes usually much larger than female’s; ocelli complete, usually clustered on weakly developed tubercle; mandible short, with rounded outer margin except Calopsocidae with somewhat angled outer margin; lacinial tip usually bicuspid; galea usually flattened; labial palpus rounded. Prothorax less bulged dorsally; pterothorax strongly bulged dorsally; mesothorax with broad precoxal bridge and narrow trochantin; metaepisternum with broad membranous region. Forewing with various coloration and markings; posteroproximal corner smoothly rounded; venation generally of Caecilius-type. Hindwing with rounded posteroproximal corner; Sc faint. Male genitalia variable; phallosome complete. Female genitalia: subgenital plate usually with distal projection extended from dorsal margin. Gonapophyses usually complete; dorsal valve swollen dorsally, usually with subapical ventral process.
