In California, texanus is most likely to be confused with 
H. niger Currie, from which it can be separated by the dots 
on the mesoscutellum, and by the markings of the coxae 
(banded with pale in texanus, mostly black in niger). The 
gonarcus and parameres of these species are shown for 
comparison; niger (Figures 36, 37) has a conspicuously 
longer mediuncus, and lacks bristles on the lateral margin 
of the paramere between the hook and the hinge.
