Cladiopsocidae

Abstract: The phylogenetic relationships of the genera of Epipsocetae were inferred on the basis of 122 morphological characters of adult specimens, corroborating the monophyly of the group with ten synapomorphies. The genera are grouped in well defined clades consistent at family level. Dolabellopsocidae, Ptiloneuridae and Epipsocidae are recognized as monophyletic families. In each family, the genera appear as monophyletic units, except in Epipsocidae, where the relationships are ambiguous and monophyly of most genera is not supported. Results indicate that Cladiopsocidae is paraphyletic; it was divided into two monophyletic families: Spurostigmatidae and Cladiopsocidae (sensu stricto), represented by the genera Spurostigma and Cladiopsocus respectively. Neurostigma is recognized as a monophyletic genus closely related to other epipsocid genera, nevertheless due to the low resolution obtained within Epipsocidae, it is not possible to decide if it is a genus of that family or if it forms a different clade at family level. The genera Parepipsocus Badonnel, previously considered as incertae sedis, and Dimidistriata Li & Mockford, previously placed tentatively in Dolabellopsocidae, are included in Epipsocidae. Loneuroides, Terryerwinia and Timnewia are recognized as valid genera. Two well defined clades are recognized within E pipsocidae, one with exclusively American genera, and the other that includes Asiatic and American genera.

Abstract: The genus Cladiopsocus Roesler is redefined. Seven new species from Central and South America and seven previously described species of Triplocania Roesler are placed in this genus.

Abstract: The results of a survey on the species diversity of the families Cladiopsocidae and Dolabellopsocidae (Psocodea: ‘Psocoptera’: Psocomorpha: Epipsocetae) in Valle del Cauca and in the National Natural Park (NNP) Gorgona, Colombia, are presented. The specimens studied were collected in the context of two scientific projects, in which 12 species in the two families were identified, five in Cladiopsocidae and seven in Dolabellopsocidae. In the first family, Cladiopsocus presented a new record in the country and four new species; in the latter, two genera were identified, Dolabellopsocus , with three new species and two new records, and Isthmopsocus , with two new species. This study presents the description of the nine new species from Valle del Cauca and NNP Gorgona, the new records for Colombia and identification keys to the neotropical species of both families.

Abstract: Ten species of Cladiopsocus Roesler were identified among recent collections from the Colombian departments of Amazonas and Putumayo. Eight new species were found, five from Putumayo and three from Amazonas, that are here described and illustrated. C. ramulosus (Enderlein) and C. domesticus (New) were found in the Putumayo department. The number of species in the genus is increased to 28, with two from Angola, and 26 from the Neotropics. An identification key to the males of the neotropical species is included.
