Abstract

GARCIA ALDRETE, Alfonso N.. A new species of Lachesilla (Psocodea: 'Psocoptera': Lachesillidae) from Dominica, representing a new species group. Rev. Mex. Biodiv. [online]. 2011, vol.82, n.2, pp.481-484. ISSN 2007-8706.

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.

Keywords : taxonomy; Lesser Antilles; Lachesilla species groups; new species.
