Bioacoustics of Ceraiaella zebrina

Description. Male ( holotype ). General appearance very similar to that of nominotypical subspecies (see Cadena-Castañeda 2015), but body colouration less spotted: body yellowish (greenish in living condition) with rose eyes, with almost whitish both lower half of pronotal lateral lobe and gena under eye, with light brown distal two thirds of antenna, upper part of pronotal lateral lobe, areas on pronotal disc along its lateral and posterior edges, stridulatory vein of left tegmen, two large dorsal spots in proximal half of hind femur, apical part of this femur, four transverse bands on hind tibia (proximal band poorly distinct and located only on dorsal half of tibia) and distal half of cercus, with transparent most part of hind wing, with brown distal half of epiproct, and with dark brown proximal third of cercus (colouration and structure of some body parts illustrated in Figs 257–262 ). Male genitalia with a pair of large and more or less rounded semisclerotized structures having numerous very small denticles ( Fig. 266 ). Female . Colouration and external structure of body as in male, but hind femur with smaller most proximal spot, hind tibia without proximal darkened band, abdominal apex unspecialized (typical of this tribe in structure) and with dark brown cerci and a pair of rather large lateral spots on proximal half of epiproct ( Fig. 263 ); genital plate and ovipositor ( Figs 264, 265 ) almost identical to those of C. triannulata Hebard, 1933 , but ovipositor somewhat shorter than in C. z. zebrina Cadena-Castañeda, 2015 . Length (mm). Body: male 18.0, female 15.0; body with wings: male 35.0, female 38.0; pronotum: male 4.0, female 3.9; tegmina: male 28.0, female 28.5; hind femora: male 18.0, female 19.0; ovipositor 6.5. Comparison. The new subspecies differs from C. z. zebrina ( Brazil : state Amazonas) in the clearly less spotted hind femora and somewhat shorter ovipositor (its length is 6.5 mm in C. z. pudica subsp. nov. and 7.2–7.8 mm in the nominotypical subspecies).
