Morphological analysis of three populations of Anopheles (Nyssorhynchus) nuneztovari Gabaldón (Diptera: Culicidae) from Colombia

Based on the results of comparative analyses of 1,039 specimens of several progenies of Anopheles nuneztovarifrom three localities in Colombia, eight costal wing spot patterns were observed. Patterns I and III were the most frequent: 77.96% and 11.36%, respectively. Using the diagnostic characters ratio of the length of the basal dark area of hind tarsomere II/length of hind tarsomere II, ratio of the length of the humeral pale spot/length of the pre-humeral dark spot, and the ratio of the length of the subcostal pale spot/length of the distal sector dark spot (DS-III2/Ta-III2, HP/PHD, SCP/DSD) approximately 5% of the adult females were misidentified as a species of Nyssorhynchus, different from An. nuneztovari. Approximately 5% of the specimens showed DS-III2/Ta-III2 ratio less than 0.25 (range 0.21 - 0.24), and among them 3.34% shared a HP/PHD ratio less than 1.50. Consequently, 1.52% of An. nuneztovari individuals can be misidentified as Anopheles oswaldoi. In those specimens with the DS-III2/Ta-III2 ratios higher than 0.25, 34.45% displayed SCP/DSD values greater than 0.50 and of these, 3.65% displayed HP/PHD values greater than 1.8. This combination of characters could lead one to misidentify samples of An. nuneztovari as Anopheles rangeli. Similarly, 2.43% of the females could be identified erroneously as either Anopheles aquasalis or Anopheles benarrochi. Individuals with a HP/PHD ratio greater than 2.0, could be misidentified as Anopheles trinkae, Anopheles strodei or Anopheles evansae. A distinct combination of diagnostic characters for An. nuneztovari from Colombia is proposed.

New species of Euplocania Enderlein (Psocodea: 'Psocoptera': Psocomorpha: Ptiloneuridae) from Colombia.

Seven species of Colombian Euplocania, are here described and illustrated, they increase to 16 the number of species in the genus, eight of which are endemic to Colombia. A new species group is also described.

A pair of new sister species of Loneura (Psocodea, ‘Psocoptera’, Ptiloneuridae) from Valle del Cauca, Colombia, representing a new infrageneric group

Abstract Two sister species of Loneura, from Valle del Cauca, Colombia, are here described and illustrated. They constitute a new species group that modifies the scheme of classification, proposed earlier for the genus by García Aldrete et al. (2011b). The new group is characterized by having the central sclerite of the male hypandrium with four posterior projections. A key to the males of Group II is included. The types are deposited in the Entomological Museum of the Universidad del Valle. Colombia may prove to be the most species rich area for Loneura.

Elaphopsocoides, a new genus of Psocidae (Psocodea: ´Psocoptera´) from Valle del Cauca, Colombia

Two new species of Elaphopsocoides n. gen. from Valle del Cauca, Colombia, are here described and illustrated. The new genus is related to Elaphopsocus Roesler, but differs from it mostly in the hypandrial projections and in phallosome structure. The female subgenital plate has a distinct, median, posterior projection. The types are deposited in the Entomology Museum, Universidad del Valle (MUSENUV), Santiago de Cali, Colombia.

Acantholachesilla gen. n. (Psocodea:'Psocoptera': Lachesillidae: Eolachesillinae: Graphocaeciliini) from Valle del Cauca, Colombia

Acantholachesilla saltoensis gen. et sp. n. is described from Valle del Cauca, Colombia, in the Lachesillidae, tribe Graphocaeciliini (Eolachesillinae). The genus is related to Dagualachesilla and Dagualachesilloides that occur in the same area, differing from them in the male clunial projection, phallosome, and female subgenital plate and gonapophyses.

The genus Waoraniella García Aldrete (Lachesillidae: Eolachesillinae: Waoraniellini) in Colombia: Two new species from the Andean region

Two species of Waoraniella from Valle del Cauca, represented by both sexes, are here described and illustrated. The new species were found in the Andean region, between 1000-2000 m above sea level, constituting the first record of the genus outside the Amazon Basin. An identification key and a distribution map of the known Waoraniella species is included.

New species and records of Cladiopsocus Roesler (Psocodea: ‘Psocoptera’: Psocomorpha: Cladiopsocidae) from Colombia

Thirteen species of Cladiopsocus Roesler, from the Colombian departments of Caquetá, Chocó, Magdalena, Nariño, Norte de Santander and Putumayo are here described and illustrated. New records of eight described species of Cladiopsocus, from the departments of Caquetá, Cauca, Quindío and Valle del Cauca are included. The number of species in the genus is increased to 41, of which 27 are Colombian. An updated identification key to the males of the genus is included, as well as a map of species distribution.

New species of Euplocania Enderlein (Psocodea: ‘Psocoptera’: Psocomorpha), in three species groups, from Colombia and Ecuador

Eight species of Euplocania from Colombia, in species groups Bonaverensis, Enderleini and Patinoi, are here described and illustrated. They raise to 40 the number of species described in the genus, 27 of which are found in Colombia. Of the Colombian species, one is shared with Ecuador and one is shared with Brazil and Peru. A key to identify the males of the species here described is included.

New species of Prolachesilla Mockford & Sullivan (Psocodea: ‘Psocoptera’: Lachesillidae: Graphocaeciliini) from Bolivia and Mexico

The genus Prolachesilla Mockford & Sullivan presently includes nine species, all described when the genus was erected; since then, no other species have been discovered. Here, we describe and illustrate one Bolivian and three Mexican species. This is the first record of Prolachesilla from Bolivia. A key to the species of the genus is included.

Seven new species of Loneura Navás (Insecta: Psocodea: ‘Psocoptera’: Ptiloneuridae) from Valle del Cauca, Colombia

Seven species of Loneura from natural areas of Valle del Cauca, Colombia, are described and illustrated. The female of L. andina is described for the first time. Two additional species, known only from the National Natural Park Gorgona (Cauca), are also recorded in Valle del Cauca. The new species are assigned to the infrageneric groups known in the genus. An identification key to males of Loneura is included.
