González-Obando, Ranulfo, Carrejo-Gironza, Nancy & Aldrete, Alfonso Neri García, 2022, Changes in the genus Euplocania (Psocodea: Ptiloneuridae): invalidation of the species group Marginata and establishment of the species group Uariniensis, with description of two new species, Zootaxa 5129 (1), pp. 129-136 : 130-131

Species Group Uariniensis

Diagnosis. Forewings with a pigmented marginal band from R4+5 to cu1 and cu2 cells ( Fig. 1 ). Pterostigma rounded, not angulate nor extended towards Rs. Hindwings with a pigmented marginal band from R4+5 to cu1 and cu2 cells ( Fig. 2 ). Hypandrium of three sclerites, central one large, with two median, close together, sclerotized, acuminate or distally widened posterior projections, located ventrally to a distally acuminate membranous projection ( Fig. 5 ). Phallosome with three pairs of endophallic sclerites ( Figs 6 and 11 ), mesal endophallic sclerite fused, inverted U-shaped, with short, lateral laminar processes, postero-mesal sclerites elongate, narrow and laminar ( Figs 12–15 ), basally fused to lateral process, apically acuminate and connected to the external parameres. Anterior sclerites small, transverse, lateral sclerites bow-shaped, apically directed mesally and with variable processes. Species included: E. atlantica Silva-Neto, 2021 , E. macuxi Pereira et al., 2022 , E. uariniensis Silva-Neto et al., 2019 , and two more species described below.

Key to the species of the group Uariniensis (males)

1. Central sclerite of the hypandrium with the two posterior median processes distally wide and curved slightly inward, each arm machete shaped (see Fig. 6 in Pereira et al. 2022)......................................... E. macuxi Pereira et al.

- Central sclerite of the hypandrium with the two posterior median processes distally acuminate ( Figs 5 and 10 )........... 2

2. Mesal endophallic sclerite with anterior margin aligned with the anterior margin of the lateral processes, appearing as a substraight anterior margin; anterior sclerites smaller than in the other three species........... E. uariniensis Silva-Neto et al.

- Mesal endophallic sclerite with anterior margin convex, or medially concave, lateral processes not forming a sub-straight line with the anterior margin of the sclerite ( Figs 6 and 11 )....................................................... 3

3. Lateral endophallic sclerites with concave laminar process apically, clearly widened, mesal endophallic sclerite with rounded anterior margin, not concave medially ( Fig. 11 )............................................................. 4

- Lateral endophallic sclerites apically with process not widened or developed as in the previous ones, mesal endophallic sclerite usually with medially concave anterior margin ( Figs 6 , 12, 14, 15 )........................... E. guticortesorum n. sp.

4. Posterior processes of the central sclerite of the hypandrium distally narrow; mesal endophallic sclerite basally narrow, apical process of lateral endophallic sclerite posteriorly wide, and distally curved outward (see Fig. 7 in Silva-Neto 2021).......................................................................................... E. atlantica Silva-Neto

- Posterior processes of the central sclerite of the hypandrium distally more widened than in the previous species ( Fig. 10 ); mesal endophallic sclerite basally broader than in the previous species, apical process of the lateral endophallic sclerites with concave laminar and crescent-shaped process ( Fig. 11 )................................................. E. wilsoni n. sp.
