Length of visible labial segments I: II: III = 0.86: 1.61: 0.17. Length of pronotum from anterior margin of anterior pubescent area to level of posterior protuberances 1.27, greatest width of pronotum 1.61, greatest width of thorax (metapleuron) 1.88. Medial length of abdomen in dorsal aspect 3.8, greatest width 3.2. Lengths of femur, tibia, and tarsus (segments I and II) of fore leg 2.02, 1.95, and 0.44 (0.32 and 0.15); of mid leg 1.95, 1.81, and 0.36 (0.31 and 0.12); of hind leg 2.51, 2.48, and 0.46 (0.17 and 0.34), respectively; greatest widths of fore, mid, and hind femora 0.52, 0.46, and 0.50, respectively. Etymology. The specific name from the Greek δεɭνOς, δεɭνO- (latinized as deino -) ‘enormous, terrible’ and Greek ρυγχOς (latinized as rhynchos ) ‘beak’, referring to the very robust labium of the species.
