A new species of Lachesilla (Psocodea: ‘Psocoptera’: Lachesillidae) from Dominica, representing a new species group

Resumen

A new species of Lachesilla, from Cabrits National Park, St. John’s Parish, Dominica, is here described
and illustrated. The phallosome is V-shaped, and it is autapomorphic in having the distal ends of the apodeme arms
articulated to each clasper. Based on these characters, a new species group is created, close to the L. forcepeta and
L. palmera species groups (the latter also diagnosed in this paper). The holotype is deposited in the National Insect
Collection (CNIN), Instituto de Biología, Universidad Nacional Autónoma de México, Mexico City.
