Emilie Bess and Kevin P. Johnson

Containing group: Epipsocetae

Introduction

Dolabellopsocidae contains three genera and 37 species. Dolabellopsocus and Isthmopsocus are distributed in Central and South America. Aurorpsocus is found in China.

Characteristics

Synapomorphy

Legs: Pulvillus of pretarsal claw is curved and broad.

General Characters

Head: Antennae 13 have segments.
Legs: Tarsi have 2 segments.
Wings:

Forewings:

Pterostigma is very narrow (length is 7x width), free of vein M.
Areola postica is long and narrow.
Veins Rs and M are joined by a short crossvein or a single point of contact.
Forewing has 2 anal veins (A2 is present).
Forewing veins have hairs arranged in 2 or more rows.
Hairs on forewing margin do not cross one another.

Hindwing:

Margins have hairs all around.
Hindwing veins have hairs arranged in 2 or more rows.

Male: Phallosome is pointed posteriorly.
Female:

Gonapophyses are reduced: dorsal and external valves are completely fused.

Dorsal valve is well developed, fused with external valve.
Ventral valve is absent.
External valve is narrow, fused with dorsal valve.

How to Know the Family

Antennae 13 have segments.
Tarsi have 2 segments.
Forewing:

Pterostigma is very narrow (length is 7x width).

Veins Rs and M are joined by a short crossvein or a single point of contact.

Forewing has 2 anal veins (A2 is present).

Hindwing:

Margins have hairs all around.

Family Monophyly

Monophyly of the family Dolabellopsocidae is supported by these morphological characters: pulvillus of pretarsal claw curved and broad, forewing pterostigma very narrow (length is seven times its width), and male clunium with ornamentations on the posterior median border (Casasola-Gonzalez 2006, Yoshizawa 2002).
