Figures 5 , 6D Diagnosis: The new species can be easily distinguished from its congeners by the form of male cerci, that presents the apex truncated, dilated, with a lateral triangular spine-like process, and a medial triangular process, much larger than lateral process, with apical margin dentate. Etymology: The specific epithet honors Dr. Edison Zefa, who has made several and significant contributions to the knowledge of Brazilian orthopterans, concerning mostly crickets. Description: Holotype male ( Fig. 5 , 6D ): Medium-sized, yellowish, probably green in life ( Fig. 5A ). Head ( Fig. 5B, C ): Fastigium of the frons triangular; apex in a small protuberance; with a small ocellus on middle.Antennal sockets dilated at base. Fastigium of the vertex triangular; a little globose at apex; with a large and deep sulcus on middle that not reaches apex. Thorax: Pronotum plain-colored but with some small reddish punctations. Pronotal disc ( Fig. 5C ) with anterior margin almost straight and posterior margin convex; furcal sulci open umbrella-shaped; larger in the posterior region. Lateral lobes ( Fig. 5D ) smaller than pronotal disc, wider than long; anterior margin straight, posterior margin almost straight; humeral sinus presenting an angle of ca. 90º. Tegmina ( Fig. 5A , 6D ) shorter than hindwings; anal and costal margins almost parallel; Sc curved; R with eight bifurcation that reaches costal margin; M long, following R in all extension; MP leaving M after the middle of tegmina, with one bifurcation; MA with one bifurcation; CuA very long and curved, with two bifurcations; one vein between MP and CuA; A1 brownish, stridulatory area with brownish stains ( Fig. 5F, G ). Mesobasisternum ( Fig. 5E ) with anterior margin almost straight; lateral lobes triangular, leaf-like, distant in posterior region. Metabasisternum ( Fig. 5E ) triangular, not elevated on middle; anterior margin straight; lateral lobes demilune shaped, almost touching in the posterior margin. Abdomen: Tergite X with posterior margin straight. Epiproct moderately big, triangular. Cercus ( Fig. 5H, I ) not very long; curved to the medial region; apex dilated, truncated, but with three spines. Subgenital plate ( Fig. 5H, I ) trapezoidal; posterior processes rhomboid, larger than long. Genitalia : Phallus completely membranous but with anterophallic apodemes on base of dorsal lobe near ejaculatory vesicles; lower fold of ventral lobe quite large and long; ejaculatory vesicles quite large.

Measurements (mm): Holotype : BL: 17.1; TegL: 28.5; HW: 2.98; PrL: 3; PrH: 3.2; FLiii: 15; TLiii: 16.5; SPL: 2.2; CL: 3; SFL: 1.1; TN: 46. Remarks: A. ( Anaul. ) zefai sp. n. belongs to the Subinermis species group of Anaulacomera ( Anaulacomera ) , and within another seven species of the group, it is closely related to A. ( Anaul. ) apicidentata Caudell. The new species can be differentiated from the latter by the form of male cerci, which bears a medial subapical spine in A. ( Anaul .) apicidentata and three apical spines in the new species. The apical spine is also present in A. ( Anaul .) caudata sp. n. , A. ( Anaul. ) metropolitana , A. ( Anaul .) spatulata Hebard, but it varies in form in all species, being long in A. ( Anaul .) metropolitana , and A. ( Anaul .) caudata sp. n. , medium sized in A. ( Anaul .) zefai sp. n. , and small in A. ( Anaul. ) spatulata . The width of the cerci is very similar to A. ( Anaul. ) apicidentata , and similar to A. ( Anaul. ) metropolitana , and A. ( Anaul. ) caudata sp. n. The male subgenital plate is quite similar to A. ( Anaul. ) subinermis and A. ( Anaul .) cautada sp. n. , and differs from A. ( Anaul .) metropolitana and A. ( Anaul .) brevicolis by the absence of a medial projection on apex in these last species.
