Petalops jactatus sp. nov. differs from other species by having the head dorsally and meta-acetabulae pale orange; dorsal abdominal segments III–VI pale orange, VII black with middle third of anterior margin pale orange, and VIII–IX black. In P. proletarius and P. virago the head dorsally is black with the space between eye and ocelli and short longitudinal stripe between ocelli pale yellow; meta-acetabulae black to dark castaneous with bluish-green reflections; and dorsal abdominal segments III–IX black with pale yellow median longitudinal stripe running from III to middle third of VII segment.
