Amyot & Serville, 1843
Diagnosis.
Body large (15.7–21.0 mm) and wide (5.1–7.0 mm). Labium reaching between metacoxae. Antennomere 1 long in both sexes, invariably longer than antennomere 2, as long as or sometimes even longer than pronotum. Sexual dimorphism well expressed, callar lobe strongly gibbose in males (
Fig. 13
), weakly gibbose in females (
Fig. 14
). Profemora in males strongly incrassate, ventral surface with longitudinal furrow in its entire length bordered with a number of spines on both sides (
Fig. 5
). In females profemora distinctly more slender, with fewer spines. Protibia ventrally with a strong anteapical tooth and a row of small denticles along its entire length in males (
Figs 5
,
15
), unarmed in females. Mesofemora of males ventrally with a row of small denticles, these missing in females. Allometry of males exists: the sexually dimorphic characters are much more expressed in some males than in others. Stridulatory organs in form of a large tooth (strigil) on protrochanter, matching a depression on ventral surface of procoxa (plectrum) (
Figs 1−2
). Peritreme of metathoracic scent glands horizontal, more or less scimitar-shaped with rounded apex, from ostiole directed laterad to slightly posterolaterad (
Figs 3−4
). Paramere with apex longer and narrower, outer margin basally angulately produced (
Figs 8−12
).
Included species.
There are three species placed in
Physopelta
s. str.
, all of them distributed in the
Oriental Region
. I am not aware of any undescribed species.
