Bioacoustics of Agaporomorphus sharynae

Diagnosis. Agaporomorphus sharynae sp. n. lacks a distinctive bursa copulatrix in the female which distinguishes it from other genera within Copelatinae . The new species is a member of the A. knishi group sensu K.B. Miller (2005) . Members of this group have convoluted male genitalia with series of setae on the dorsal surface ( K.B. Miller, 2005 ). Male specimens of A. sharynae sp. n. differ from the other members of the A. knishi group by the combination of absence of modified antennae, an apparent stridulatory device, and the medio-apical spine on abdominal ventrite V. Agaporomorphus silvaticus K.B. Miller, 2005 also lacks modified antennomeres, but that species has very different male genitalia ( Figs 11–13 ). Males of A. sharynae sp. n. have modified anterior protarsal claws with a large basal expansion and subbasal emargination along the ventral margin with the posterior claw slightly shorter than the anterior ( Fig. 18 ). Unique features of the male genitalia of A. sharynae sp. n. include atypically large apical, transparent lobes and the setae on the median lobe present only as a series of sparse, short setae along the left side of the dorsal surface ( Fig. 2 ). The lateral lobes are characterized by a large, membranous subapical lobe and two large regions of setae with those in the medial cluster long and prominent ( Fig. 4 ).
