New species and records of Psocoptera (Insecta) from Roraima State, Brazil.

Abstract

Psocoptera. from Ilha de Marcica and Pacaraima, Roraima State, Brazil, representing 103 species are recorded. Sixty-two are new to science. and are described and figured, representing genera Echmepteryx(2), Tapinella(3), Musapsocus, (1), Seopsocus(3),Isth-mopsocis(3), Dolabellopsocus(6), Epipsocus(5), Neurostigma.(1), Nctiopscus(1), Cae-cilius (6) , Enderluinella (1), Xanthocarcilius(1) , Polypsocus(3) , Scytopsocus(1), ar-chipsocus(1), Lachesilla(4), Notolachesilla(1) , Perispsocus(4), Dactylopsocus (1) , Metylophorus(3), Blaste.(4), Lichenomiae(3), Myopsocus (3). Genus Notarchispsu. gen. is erected for Archipsocus macrurusNew and a new species. Genus MonocladellusEu-derlein in placed in synonymy of, PolypsocusHagen. South American species assigned to genus LophopterygllaEnderlein by New (1979) are. reassigned to Myopscus and represent a parallel development in the latter genus.

Molecular systematics of the barklouse family Psocidae (Insecta: Psocodea: ‘Psocoptera’) and implications for morphological and behavioral evolution

“…When the evolution of male genital structure was examined, information from a closely related bisexual species was adopted for those taxa (i.e., T. circularoides cf. T. gonzalezi: Mockford, 1991, T. sp. cf.…”

Systematics and biogeography of the New World species ofTrichadenotecnumEnderlein (Insecta: Psocodea: ‘Psocoptera’: Psocidae)

“…Diagnosis: This species is similar to T. gonzalezi (Williner) but can be separated from it by the following character states: darker background colour of forewing; apical margin of egg guide slightly bilobed; pigmented arms of subgenital plate broadly separated; ventral valve of gonapophyses shorter (Mockford, 1991). The T. circularoides – T. gonzalezi complex can be easily distinguished from T. peruense sp.…”

Seven new species of Lachesilla (Psocodea: 'Psocoptera': Lachesillidae), in the group forcepeta from the Amazon Basin

“…The structural plan of the male genitalia in group forcepeta has proven to be quite successful, and the ornamentation of the claspers with scales, setae, spines or small denticles, add to the enormous variation observed in the group: L. asperiforceps García Aldrete, from Mexico, Guatemala and Nicaragua, and several related undescribed species from southern Mexico, present a dense field of microspines on the surface of the claspers; the distal end of the claspers in L. spiniforceps García Aldrete, from the Tambopata Reserved Zone in the Peruvian Amazonia present a field of medium-long spines, and L. yanomami Mockford, from Roraima, Brazil, L. yanomamioides García Aldrete, from Mexico, Guatemala and Trinidad, and L. gracilis García Aldrete, from SE U. S. A., Mexico, Belize and Guatemala, have a row of fine denticles along the inner edge of the distal half of the claspers (García Aldrete 1988, 1996, 2001, 2008Mockford 1991). The function of these ornaments is unknown, although presumably, they could play a role in mating, or in close distance species recognition.…”
