 Etymology . fulmineus: Latin = of lightning. This 



specific name was probably chosen because of the resemblance 



of the jagged elytral markings to a lightning bolt. 



Remarks . Ischyrus fulmineus is most similar to I. 



insolens and I. n. sp . 16; I. insolens lacks basal pronotal 



spots, I. n. sp . 16 lacks the black connection between stria 



V and VI on the central elytral band.
