Bioacoustics of Conocephalus (Megalotheca) namibius

Figs 15 , 36, 37 Etymology: From Namibia . Description: Male . Coloration greenish yellow with a pair of hardly lighter (yellowish) stripes along lateral edges of disc, light brown area between them, yellowish proximal half of tegminal Sc, brownish both its distal half and stridulatory vein of upper tegmen, brown both plectrum of lower tegmen and majority of longitudinal veins in hind wings, semitransparent rest of wing venation, and transparent membranes of all wings (hind legs missing). Shape of head in profile as in Fig. 15 ; shape of both anterior part of head (from above) and proximal part of antennae similar to that shown in Fig. 12 , but rostrum hardly shorter; interspace between eye and posteroventral corner of epicranium (situated behind hind part of subgena) distinctly shorter than fore femur (ratio 1.2). Pronotum also similar to that of C. phasma (from above; Fig. 12 ), but slightly shorter and with lateral lobes higher and somewhat different in shape ( Fig. 15 ). Both pairs of wings long, extending much behind abdominal apex; tegmina narrow, and 4 mm not reaching apex of hind wings; stridulatory apparatus in lower (right) tegmen very similar to that of C. marcelloi ( Fig. 17 ); this apparatus in upper (left) tegmen very similar to that of C. phasma ( Fig. 12 ); costal area in proximal half of tegmina normally developed (but not wide); in distal half of tegmina, this area strongly reduced; tegminal RS and MA forming a single longitudinal vein with 6 or 7 short distal branches (base of RS almost indistinct, similar to crossvein; R appears like a vein lacking branches, as its base has distinct connection with only RA). Abdomen rather long, with 10 th tergite as in Fig. 36 ; cerci elongate (but less elongate than in C. phasma , C. longiceps , and C. marcelloi ), with almost acute apex and distinctly curved large denticle situated at middle of cercus; medial edge of cercus between its apex and this denticle convex at middle ( Fig. 36 ); genital plate with hind part almost identical to that of C. marcelloi ( Fig. 34 ); genital sclerites as in Fig. 37 . Female unknown. Length (mm): Body 18, body with wings 29, pronotum 3.7, fore femur 2.4, tegmen 18.5.
