Diagnosis. Body length 240–425. Funicle 7-segmented with fu 2 shorter than or equal to fu 1 and fu 3 ( Figs 341 View FIGURE 341 , 345 View FIGURES 342–345 , 352 View FIGURES 350–352 ); mandibles when closed overlapping medially ( Fig. 350 View FIGURES 350–352 ), each with 2 small apparently equal teeth; occiput without lines, sulci or carinae except for a median transverse sulcus of variable length ( Figs 343 View FIGURES 342–345 , 351 View FIGURES 350–352 ) just above foramen; fore wing behind venation with posterior margin forming an evenly rounded lobe ( Figs 346, 347 View FIGURES 346, 347 ). Male body length 110–140 (2 card-mounted specimens). Body without wings, eyes, ocelli and mouthparts; antenna and tarsi greatly reduced ( Figs 356–359 View FIGURES 356, 357 View FIGURES 358–363 ). Mockford (1997) recorded body length measurements for 8 slide-mounted specimens as 139–240 μm.

Discussion. Dicopomorpha belongs to the Alaptus group of genera, together with Alaptus , Callodicopus , Dicopus , and Litus . It is most similar to Callodicopus but does not have a thick vertexal trabecula extending transversely across the back of the head. It differs from Dicopus by the mandibles crossing medially when closed, the head ventral to lower eye margin not narrowing so appreciably, and the fore wing wider distal to venation. In the Nearctic, males have never been collected in the wild; the only males known are for the single included species and were laboratory reared from a culture of Psocoptera.

Nearctic hosts. Psocoptera: Lepidopsocidae .
