INTRODUCTION

Loneura Navás, 1927, is one of eleven genera in the family Ptiloneuridae (Psocodea: Epipsocetae). The genus was re-defined, and some of the species included in it were transferred to Ptiloneura Enderlein (García Aldrete et al., 2020). Loneura presently includes 36 described species (García Aldrete et al., 2011a, 2011b; Mendivil Nieto et al., 2017; Moura Lima et al., 2019; González Obando et al., 2020; González Obando & Carrejo-Gironza, 2020). The species described to date have been found in Belice, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Guatemala, Mexico, Nicaragua, Panama and Peru. From samplings with led light traps and direct search in natural areas of Cuzco, Peru, two other species of Loneura were found, to reach four species recorded for this country. These two species are described and illustrated below.

MATERIAL AND METHODS

The specimens were collected with a LED light trap and direct search on tree bark, using canvas beating sheets and oral aspirators. Three specimens were available for study, they were dissected in 80% ethanol, and their parts were mounted on glass slides in Canada balsam following standard procedures. For the preparation of the plates, the protocol regularly used in other studies of psocids was followed (see González Obando et al., 2011). Color was recorded from whole specimens, observed under a dissecting microscope illuminated with cold white light at 50X. Measurements (given in µm) of parts on the glass slides (head, right wings and legs and genitalia), were taken with a micrometer, mounted on a Nikon Eclipse Ci microscope.

Abbreviations of parts measured are as follows: H: head median length (in dorsal view); MxW: maximum width of head capsule; Mx2, Mx4: lengths of second and fourth segment of right maxillary palpus, f1…fn: lengths of flagellomeres 1…n of right antenna, IO, D and d, respectively: minimum distance between compound eyes, antero-posterior diameter and transverse diameter of right compound eye, all in dorsal view of head; FW and HW: lengths of right fore- and hind- wings; W and w: width of fore- hind- wings; lp: pterostigma length; wp: pterostigma width; al: areola postica length; ah: areola postica height; F, T, t1-t3: lengths of femur, tibia and tarsomeres 1-3 of right hind leg, ctt1: number of ctenidiobothria on t1 of right hind leg. Ratios of head and wings were taken: H/MxW; H/D; PO: d/D; IO/d; FW/W; HW/w; lp/wp; al/ah (see González Obando et al., 2011). The illustrations were made from digital photographs, taken with a Canon T5i camera and Helicon Focus program, processed in a Clip Studio Paint vector graphics editor program. The scales are given in mm. The specimens are deposited in the Entomological Museum, Universidad del Valle, Santiago de Cali, Colombia (MUSENUV).

RESULTS

Description of new species

The species described below belong in group II (see González Obando et al., 2020), by having the hypandrium of a single sclerite resulting from the fusion of the proximal ends of the side sclerites to the central sclerite, this extended mesally on each side, and with two posterior projections in the middle, variously shaped (García Aldrete et al., 2011a, 2012).

DISCUSSION

The species of Loneura known in Peru is raised to four. Until 2019 the only known Loneura species in Peru was L. erwini (New & Thornton, 1988), originally described as Ptiloneura (Loneura); now L. garcialdretei González Obando & Carrejo-Gironza, 2020, and the two species described above, belong to the same species group (Group II: Hypandrium of a single sclerite resulting from the fusion of the proximal ends of the side sclerites to the central sclerite, this extended mesally on each side, and with two posterior projections in the middle, variously shaped). The species in this group are somewhat similar to those with forewings with a submarginal brown band, with segments arc-shaped, or with long spots only at the end of each cell m (Figs. 7, 13) but differ considerably in head pattern, and details of the hypandrium and phallosome. By the shape of the hypandrium L. amankii sp. nov. is somewhat similar to L. amazonica (New), but differing from it by the shape of the endophallic sclerites and by details of the hypandrium. By the coloration pattern of the head and wings. Loneura kosnipatensis sp. nov. is similar to several species of group II; by the shape of the hypandrium it is similar to L. amazonica (New). By the shape of the endophallic sclerites it is similar to L. zuluagai González Obando, Carrejo-Gironza, Panche & Garcia-Aldrete. Differs from them and from similar species in group II by the shape of the hypandrium and endophallic sclerites (Figs. 11, 12).

The number of species in Loneura is raised to 38. The number of species assigned in Group II, characterized by having the hypandrium of a single sclerite, is raised to 19 (Table 1) which constitutes 50% of the species described in the genus.

L. konispatensis sp. nov.	Both	1150	Peru
L. koreguaje González-Obando, Carrejo-Gironza, Panche & Garcia-Aldrete	Male	844	Colombia
L. misak González-Obando, Carrejo-Gironza, Panche & Garcia-Aldrete	Male	844	Colombia
L. monticola García Aldrete, González-Obando & Sarria-Sarria	Male	90-241	Colombia
L. nonuya González-Obando, Carrejo-Gironza, Panche & Garcia-Aldrete	Both	917	Colombia
L. occidentalis González-Obando, Carrejo-Gironza, Panche & Garcia-Aldrete	Both	1383-1617	Colombia
L. orucapu González-Obando, Carrejo-Gironza, Panche & Garcia-Aldrete	Both	844	Colombia
L. tatama González-Obando, Carrejo-Gironza, Panche & Garcia-Aldrete	Both	1617	Colombia
L. zuluagai González-Obando, Carrejo-Gironza, Panche & Garcia-Aldrete	Both	917	Colombia

It is pertinent to remember that the character “hypandrium of a single sclerite” is shared with five species of Euplocania in species group Bonaverensis (González Obando et al., 2018), which points to the need to clarify the relationships among the genera of Ptiloneuridae. Also, it would be advisable to consider the species known only from females (L. brasiliensis Roesler, L. erwini New & Thornton, L. lienhardi García-Aldrete, L. maesi García Aldrete, L. murui González Obando, Carrejo-Gironza, Panche & Garcia-Aldrete, and L. quinaria Navás), as well as the females with uncertain assignment to species group.

Considering the altitudinal distribution range of the known species of Loneura, the challenge is to carry out more explorations, in more areas, especially in the Amazonian foothills of Bolivia, Ecuador, Peru and Venezuela, as well as in mountainous areas of Brazil and other neotropical countries. Based on the exploratory work carried out in Colombia, the country most species rich for Loneura (Table 1) (García Aldrete et al., 2011b, 2012; Mendivil Nieto et al., 2017; González Obando et al., 2020; González Obando & Carrejo-Gironza, 2020), transferring the results of this effort to natural areas of other countries in the Amazon Basin, the number of species could probably be dramatically increased, in accordance with the megadiverse nature of these countries.
