Pseudaugochlora indistincta

description: Pseudaugochlora indistincta Almeida sp.n.
Diagnosis. This species is most similar to P. graminea, P. callaina, P. erythrogaster, and P. simulata. The female can be distinguished from those of the other species by the furrow­like depression on the apical portion of the clypeus (Fig.8 b — in P. callaina the clypeus is broadly depressed medially, Fig.8 a; in the other three species the clypeus is flat or very weakly concave); the moderately coarse and moderately dense punctures on disc of T1 (in P. callaina, P. erythrogaster, and P. s i m u l a t a the punctures are very fine intermixed with coarser punctures). The male can be distinguished by the weakly hooked F11 (strongly hooked in P. g r a m i n e a, P. erythrogaster, and P. simulata); and by the entangled and unordered hair apices of the stem of the Y­shaped hair patch (as in Fig.2 a; in P. callaina apices of hairs of the Y­shaped are ordered and aim at midline of the Ystem, Fig.2 b). and by the entangled and unordered hair apices of the stem of the Y­shaped hair patch (as in Fig.2 a; in P. c a l l a i n a apices of hairs of the Y­shaped are ordered and aim at midline of the Y­stem, Fig.2 b).

On basal area of labrum very fine, short and erect between and anterior to the two basal elevations; on scape and frons longer than on female; on S4 and S5 with hair patches forming tufts: S4 with a Y­shaped hair patch, hair apices on the stem of this patch entangled and unordered (as in Fig.2 a), S5 with two lateromedial tufts (as in Fig.2 a); on S6 moderately long, forming an apical fringe.
Sculpture: integument smooth and shiny except: outer interspace of mandible weakly microrugulose, almost smooth; disc of clypeus weakly and irregularly microreticulate, narrow basal band smooth; on vertex rough; on scutellum coarse and irregularly reticulate (reticulum reaching anterior margin); on metanotum irregularly rugulose; upper corner of the posterior surface of propodeum deeply microreticulate.
Punctures: on outer interspace of mandible absent; on supraclypeal area not beveled, moderately fine and very dense (as on frons); on vertex close to eye very fine and sparse (more than three diameters apart); on disc of mesoscutum moderately coarse and dense, sparser in areas near parapsidal lines; on scutellum moderately coarse and moderately dense, intermixed with very fine and sparse punctures, moderately fine and dense on median transverse line; on scutellum fine and moderately sparse; on T1–T3 moderately coarse and dense, finer and sparser apicad, apical margin impunctate.
Structure: epistomal sulcus forming approximately orthogonal angle (more rounded than in female); F11 weakly hooked (as in Fig.1 b); frontal carina weak and well­defined only on upper part of supraclypeal area; angle of the frontal line between supraclypeal and frontal areas gently declivous (approximately 140, as in Fig.6 a); margin of S4 emarginate, posterior marginal area of S4 and S5 depressed; seven unevenly spaced hamuli on hind wing; S7, S8 and genitalia structurally similar to those of P. graminea (Figs.3 a, 4a).
Measurements (mm). Approximate length of body = 10.2, anterior wing = 7.8. Length and width of head = 2.45, 2.87. Maximum, inferior and superior distances between eyes = 1.94, 1.30, 1.44. IOC, OOC = 0.22, 0.23; MOD, LOD = 0.34, 0.41. Length and diameter of scape = 0.73, 0.24. Length of pedicel, F1, F2, F3 and F10 = 0.12, 0.17, 0.35, 0.32, 0.28. Diameter of F5 = 0.21.

Variation: The color varies from green with bluish highlights to metallic blue with purple and green highlights; body length varies from 8 – 13 mm; microreticulate basal band varying in width from very narrow (approximately ¼ flagellar width) to almost as wide as lateral microreticulate bands; some females from the states of Santa Catarina and São Paulo possess punctation on the disc of T1 fine, resembling that of females of P. simulata (Figs.7 d,f); the depressed area on the clypeus of females from southern Brazil is slightly wider and deeper than observed in females from Minas Gerais and Rio de Janeiro states.
Etymology: the specific epithet alludes to the similarity of this species and P. g r a m i n e a, P. c a l l a i n a, and P. simulata, and the difficulty of distinguishing these species.
Distribution in Brazil: southeastern and southern Brazil, south of Minas Gerais (states of Minas Gerais, Paraná, Rio Grande do Sul, Rio de Janeiro, Santa Catarina, and São Paulo).
Period of activity: every month of the year except May, June, and September.
