Augochloropsis (Glyptochlora) Moure

Augochloropsis (Glyptochlora) Moure, 1958: 188 . Type species: Megalopta ornata Smith, 1879 , by original designation.

Diagnosis: Females of A. ( Glyptochlora ) are readily recognized by the diagnostic characteristics provided in the revision of Celis & Melo (2022) for the subgenus. In general, the male ( Fig. 1 ) is similar to the females and both sexes share the following morphological features: dorsal ridge of the pronotum strongly lamellate; pronotal lobe strongly depressed, forming a deep concavity; tegula oval, with posterior internal margin weakly notched, not producing a posterior tooth; mesoscutum foveate ( Fig. 1C ; see also fig. 7C of Celis & Melo (2022)), with sinuous elevations in lateral view (see figs. 3A, B of Celis & Melo (2022)),anterior margin strongly projected on the pronotum and lamellate,this lamella strongly emarginated medially forming a bilobed structure (see also fig. 8C of Celis & Melo (2022)), lateral regions lowered and parapsidal lines strongly elevated; axillary crest on scutellum polished and with margin strongly elevated in lateral view,near to mesoscutum; metanotum with acute posterior margin (see figs.3C, D of Celis & Melo (2022)); propodeum with posterior vertical surface strongly excavated and carinated; metapostnotum with strong central ridge; mesepisternum medially forming an acute projection like a tooth ( Fig. 2C ; red arrow), and with expansion like a sheet ventrally, near to mid coxa ( Fig. 2C ; yellow arrow); T1 with dorso-lateral line and anterior margin flattened, apparently straight in dorsal view; T1-T4 with marginal zone glabrous, wide (reaching half length of the tergum medially), somewhat depressed laterally; dorsal surfaces of T1-T3 mostly glabrous, with scarce, minute bristles, and semierect, black longer bristles close to the anterior edge of marginal zones on T3 and T4 ( Fig. 1D and Fig. 2B ; see also fig. 4D of Celis & Melo (2022)); and T1 and T2 without vibrissae.

The male shows the following differences in relation to females: vertex long (1 OD) and weakly angulate; posterior surface of head, immediately behind ocelli, not vertical as in females, giving a more swollen appearance to the head in dorsal view, and forming a weak post-ocellar transverse ridge, strongly elevated medially in frontal view (similar to the elevation in Pseudaugochlora Michener, 1954 ). Elevation behind compound eye, on vertex, weakly developed and not continuous with post-ocellar transverse ridge. Tegula oval, with posterior margin smooth, centrally weakly microtessellate, inner margin with some sparse fine punctures. Propodeum with lateral angle and areas adjacent to metapostnotum entirely foveate ( Fig. 2A ), not carinated and with irregular edges; lateral expansions of propodeum small and not well defined; posterior vertical surface of propodeum foveate with irregular edges ( Fig. 2A ). Metapostnotum with irregular margin, and with entire surface covered by strong, parallel and radial plicae ( Fig. 2A ). Gradulus of T2 weakly constricted ( Fig. 1A ). Marginal zone of T1 mostly smooth, its lateral surface with sparse fine punctures, T2-T4 almost entirely smooth ( Fig. 1D ).
