Bioacoustics of Ectecous lamelliferus

DESCRIPTION In addition to the character of the genus. General morphology Size only slightly bigger than E. tenebrosus . Fastigium, ocelli and palpi as in E. tenebrosus ; with lateral ocelli separate by a distance shorter than their own width. Coloration General coloration as on Fig. 26 . Face as in E. tenebrosus : black, with reversed Y-shaped line under median ocellus, a small yellow spot under antennal pit (in an area with many long setae), and a wider yellow area under lower angle of eye; but median yellow line thinner between antennal pits and spot under anterior angle of eye smaller ( Fig. 27A ). Maxillary palpi as in E. tenebrosus , but article 5 darker ( Fig. 27A ). Vertex ( Fig. 27B ) as in E. tenebrosus , with the most lateral yellow lines (behind the eyes) prolonged as a semi-circular line on the occiput (unnoticed in E. tenebrosus description). Pronotum ( Fig. 27B, C ) and legs ( Fig. 26 ) as in E. tenebrosus . iod pron L pron w FW L FW w FIII L FIII w TIII L Tars1-III Male holotype 1.4 2.5 3.9 7.8 5.4 12.7 2.9 10.7 2.4 Paratype male (n =2) 1.4 2.5-2.6 4.3 8-8.8 5.8-6.1 12-12.2 3.1 10.3-10.8 2.7-2.8 Mean (n = 3) 1.4 2.53 4.17 8.2 5.77 12.3 3.03 10.6 2.63 Male FWs covering abdomen up to half supra anal plate, as in E. tenebrosus . Venation ( Fig. 27D ): harp with 6 – 8 veins, mirror crossed by 4 – 5 concentric veins. Stridulatory file with 232 teeth (n=1). Subgenital plate short, truncated apically. Distal margin of supra anal plate with many long and thick setae ( Fig. 27E ). Male genitalia ( Fig. 27 F-H) Pseudepiphallic sclerite, rami, ectophallic apodemes, ectophallic fold (short and bifid) and endophallic apodeme as in E. tenebrosus (see Desutter-Grandcolas 1992b, Figs 59-61), but dorsal valves wide and thick, having the shape of nearly vertical lamellas ( Fig. 27H ), with sharp, curved denticles on lower margin ( Fig. 27G ); median lophi (= apical lobes) entirely membranous ( Fig. 27F, G ), convex on outer side, concave with abruptly vertical base on inner side. Female Unknown. Measurements (in mm) See Table 19 .
