( Figs. 1–8 ) Type material . Holotype female: Brasil, Maranhão , Mirador, Parque Est[adual] Mirador, Povoado Pindaíba (Mel), 06 ◦ 39 Ɩ 44 ƖƖ S 45 ◦ 01 Ɩ 37 ƖƖ W, Armadilha Malaise , 01-05.vi.2011 , F. Limeira-de-Oliveira , M.M. Abreu & J.S. Pinto Junior ( CZMA ). The holotype is deposited in Coleção Zoológica do Maranhão ( CZMA ), Caxias , Maranhão , Brazil . Diagnosis . Eye stalks relatively short, head in dorsal view 1.7 times as broad as mesosoma. Mesoscutellar process dorsally pointed and cone-shaped. Mt5 with lateral patch of white setae. Description . Body color ( Figs. 1 and 5 ). Body generally dark brown with ventral and lateral portions of head ( Figs. 2 and 3 ) and mesosoma ( Figs. 2 and 5 ) brown. Legs dark brown ( Fig. 5 ). Fore and hind wings hyaline. Body length: 7.15 mm , head plus mesosoma: 3.07 mm . Head ( Figs. 2, 3 and 5 ). Head punctuate, densely covered with white setae ( Figs 2 and 3 ), though less distinct, shorter and thinner, dorsally ( Fig. 3 ). Antenna 10-segmented. Length of antennal segments (in mm): scape: 0.92, pedicel: 0.08, F1 (anellus): 0.04, F2: 0.31, F3: 0.23, F4: 0.23, F5: 0.19, F6: 0.19, F7: 0.15, clava: 0.30. F2–F6 densely covered with long and depressed setae. Longitudinal sensilla arranged in multiple irregular rows (number of rows depending on length of flagellomere). Clava ( Figs. 2 and 3 ) one-segmented, but limits of fused antennomeres still slightly indicated, densely covered with long setae. Frons densely setose and entirely foveate, with basal portion wide, at least more than half width of head in frontal view. Gena short, shorter than eye length in lateral profile; with expansion around posterior margin. Figs. 5–8. Axima nordestina Barbosa, Krogmann & Azevedo sp. nov. , 5. Head and mesosoma, lateral view. 6. Wings, dorsal view. 7. Metasoma, lateral view. 8. Head and mesosoma, dorsal view. Mesosoma ( Figs. 4 , 5 and 8 ). Pronotum ( Fig. 8 ) 0.34 as long as wide; with piliferous punctures, more dense at lateral panel of pronotum. Mesoscutum with complete and broadly foveolate notauli ( Figs. 4 and 8 ); without median mesoscutal carina ( Fig. 8 ), remaining mesoscutum with piliferous punctures. Dorsal surface of axillae with piliferous punctures, posterior portion of axillae smooth with distinct patch of white setae. Axillula smooth, dorsally defined by distinct carinae. Mesoscutellum expanded dorsally into cone-shaped process, antero-medially with keel-like carina ( Figs. 5 and 8 ). Mesepisternum with distinct but shallow mesofemoral depression ( Figs. 2 and 5 ), the depression anteriorly without carina; Mesepisternum anteriorly with distinct white setae. Mesepimeron ( Figs. 2 and 5 ) glabrous, upper mesepimeron marked by deep impression, with well-marked fovea. Ventral mesopleuron with piliferous foveae; mesofurcal pit large, situated anterior to mesocoxal depression; mesodiscriminal line absent. Metanotum with metascutellar arms carinate; lateral panel of metanotum consisting of row of large fovea; metascutellum carinate, reaching anterior margin but separated from posterior margin of metanotum. Lateral panel of metapleuron with densely foveolate punctures and distinct long white setation. Ventral metepisternum anteriorly smooth, posterior portion irregularly foveolate and greatly expanded between hind coxae. Propodeum with median foveolate sulcus, and most piliferous punctures foveolate and much larger than on pro- and mesonotum. Legs ( Fig. 5 ). Forecoxa with large piliferous punctures. Meso and hind coxae setose and polished. Wings ( Fig. 6 ). Length of submarginal vein: 1.08 mm , marginal vein: 0.69 mm , postmarginal vein: 0.15 mm , stigmal vein: 0.15 mm . Metasoma ( Fig. 7 ). Length of metasomal tergites in dorsal view (in mm): Mt1 (petiole): 1.08, Mt2: 0.23, Mt3: 0.23, Mt4: 0.23, Mt5: 0.46, Mt6: 0.77, Mt7: 0.69, Mt8/9: 0.23. Petiole with indistinct, shallow reticulation; subrectangular in cross section, with four strong carinae delineating each of the dorso- and ventrolateral margins; dorsal surface with median carina along anterior ¾ ; lateral surface with additional complete length carina. Post-petiolar metasoma without microreticulation; tergites bare except Mt4–6 with distinct patches of white setae, Mt7–9 setose ( Fig. 7 ). Length of exposed part of ovipositor in dorsal view: 0.08 mm . Male . Unknown. Distribution . Maranhão , Brazil . Etymology . The specific epithet nordestina refers to its Northeastern Brazil origin. Host . Unknown.
