Anaulacomera (Analaucomera) zefai sp. n.

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.

Type Material: Holotype male, ‘ DPTO ZOOL \ UF –PARANÁ’ ‘ S. José Pinhais — PR \ Brasil ( BR277 –Km54) \ 21.III.1985 \ C.I.I.F. (Luminosa)’ ‘ DZUP 366883 ’.

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.
