ETYMOLOGY. — Species named after the lamella-shape of pseudepiphallic apical lobes in male genitalia.
DIAGNOSIS. — Species very close to E. tenebrosus Desutter-Grandcolas, 1992 by its size, coloration, male FW size and venation, but separated from that species by male genitalia (as in E. tenebrosus, except for lamella-shaped dorsal valves), its slightly more narrow FWs (length/width ratio 1.42, n= 3, against 1.53, n = 6, in E. tenebrosus), with fewer stridulatory teeth (232 against 259-264, n = 6, mean 262, in E. tenebrosus).
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.
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)
