Diagnosis

Augochlora simplex sp. nov. females have a tuberculate S1 and males have S4 with a tuft of thick setae on medioapical margin ( A. mendax species group). Females are dark green with metapostnotum entirely carinate-rugulose, being similar to A. tenax , but can be separated from the latter by the elongate head, mesoscutum and scutellum smooth among punctures and anterior surface of T1 with sparse tiny setae among long setae. Differently from other species of the subgroup, the hind basitarsus of the male is parallel sided and S5 gently depressed transversally on median surface.

Description

Female. Measurements. Distance between eye notches: 1; head length: 1.7; clypeus width: 0.7; clypeus length: 0.3; clypeoantennal distance: 0.3; clypeus ocellar distance: 1.2; intertegular distance: 1; T1 width: 1.3; T2 width: 1.5; body length: 6.3. Head. Labrum basal surface light brown; basal elevation not well defined. Mandible mostly dark brown, medially light brown; distance between base and apical tooth about 4× mandibular basal width. Clypeus disc mostly green, apical dark band as long as 1.5 OD; with shallow punctures (I <PD); lateral teeth prominent. Supraclypeal area dark green; upper portion densely punctate, becoming sparser (I <PD) near epistomal suture.

Preoccipital carina as thick as 0.3 OD laterally. Gena green. Post-gena weakly punctate, becoming microreticulate near hypostomal carina; with sparse setae <3 OD. Hypostomal carina very low, <0.3 OD, not prominent anteriorly. Mesosoma. Dorsolateral angle of pronotum obtuse in dorsal view. Fore leg coxa to femur dark brown, coxa and femur with faint green reflections, tibia and tarsus light brown. Mesoscutum dark green with golden reflection; anterior portion contiguously punctate, becoming sparser (I <PD) posterior to median line, disc smooth among punctures. Scutellum dark green; sublateral surfaces with I <PD, smooth among punctures. Mesepisternum dark green; contiguously punctate anterior to mesepisternal groove, the remainder of lateral surface with I <0.5 PD, smooth among punctures, with well-defined punctures at mid height right after mesepisternal groove. Mid leg coxa to tibia brown, tarsus light brown. Metanotum dark green. Metepisternum dark green; with crowded punctures. Hind leg coxa to tibia brown, tarsus light brown. Metapostnotum as long as scutellum; entirely carinate-rugose. Propodeum dark green; with crowded punctures near metepisternum; posterior surface less than 1.5× higher than wide between lateral carinae. Metasoma. T1 mostly dark brown with faint green reflection, dorsally dull; entirely weakly punctate; anterior surface with sparse tiny setae among long setae. T2–4 mostly dark brown with faint green reflections; with weak and dense punctation. T5 dark brown. S1 with a tuberculate median elevation. S1–6 dark brown, becoming lighter apically; S4 and S5 with long setae (> 3 OD) on posterior half.

Male. Measurements. Distance between eye notches: 1.2; head length: 1.7; clypeus width: 0.4; clypeus length: 0.4; clypeoantennal distance: 0.3; clypeus ocellar distance: 0.9; intertegular distance: 1; T1 width: 1.3; T2 width: 1.4; body length: 6.2. Head. Labrum basal surface creamy white. Mandible creamy white, apex brownish. Clypeus disc mostly green with golden reflection, apex creamy white; slightly longer than wide; with shallow punctures (I <PD). Supraclypeal area golden; densely punctate, I <PD. Lower paraocular area golden; densely punctate near antennal socket; sparse setae with about 1.5 OD, shorter decumbent setae in between. Frons dark green with blue reflection; frontal line becoming faintly indicated above antennal sockets level. Flagellum not crenullate; F1 subequal to F 2 in length. Preoccipital carina as thick as 0.5 OD laterally. Gena dark green with golden reflection. Post-gena mostly punctate, becoming smooth near hypostomal carina; with relatively dense setae <3 OD. Hypostomal carina very low, <0.3 OD. Mesosoma. Dorsolateral angle of pronotum rounded in dorsal view. Fore leg coxa to femur brown, coxa and femur with strong green reflections, tibia and tarsus yellow. Mesoscutum dark green with golden reflection; sparsely punctate, becoming sparser (I <2 PD) posterior to median line, disc smooth among punctures. Scutellum dark green with golden reflection; sublateral surfaces with I <2 PD, smooth among punctures. Mesepisternum dark green with golden reflection; punctate anterior to mesepisternal groove, the remainder of lateral surface with I <PD, smooth among punctures, with shallow punctures at mid height right after mesepisternal groove. Mid leg coxa to femur dark brown, femur with strong green reflection, tibia light brown, tarsus yellow. Metanotum green with golden reflection. Metepisternum green with golden reflection; densely punctate, I <0.5 PD. Hind leg coxa green, trochanter and femur dark brown with faint green reflections, tibia light brown, tarsus yellowish, basitarsus about 5× longer than wide, not narrowed apically. Metapostnotum green with golden reflection; as long as scutellum; entirely carinate-rugose. Propodeum dark green with golden reflection; lateral surfaces imbricate among punctures; posterior surface less than 1.5× higher than wide between lateral carinae. Metasoma. T1 mostly dark brown, with faint dark green reflection; densely punctate on disc, I <PD, sparser on lateral surfaces; apex not inflexed. T2–6 dark brown with faint dark green reflections; with weak and dense punctation. T7 dark brown. S1 dark brown with faint dark green reflection. S2–6 brown, becoming lighter apically. S4 with a tuft of thick setae on medioapical margin. S5 median surface gently depressed transversally; without glabrous patch medially. Genitalia: not dissected.

Etymology

Latin meaning simple, in reference to the subtle modifications on male sterna and hind basitarsus when compared with A. mendax subrgroup species.

Distribution

Brazil (Minas Gerais).
