Genus Helesius
Explanation of Names
Helesius Casey 1899
Numbers
2 spp. n. of Mex. (1)
Identification
This genus is distinctive in the North American hyperaspine fauna because the legs are compressed and the hind femur is extremely robust.
Also, the apex of each tibia is thickened and excavated, Gordon's Figures (1)
Gordon's Key:
Punctures on head and elytron dense, Colorado, Montana .... nigripennis (LeConte)
Punctures on head not apparent, barely perceptible, punctures on elytron fine, indistinct; Texas .... nubilans Casey (1)
Range
Rocky Mtns to s. TX (1)
Remarks
very limited number of records for both spp. (1)
a female spmn in the USNM from San Antonio, Texas has an entirely red pronotum and is larger (3.5 mm long) than normal for H. nubilans. There is a good possibility that the specimen represents an undescribed species, but a male is needed to ascertain this. (1)
