I was able to get some ventral shots of my H. arizonensis and it appears to be female. I'm hoping some of the experts here can confirm this. I'm basing my determination on the following observations:
Photo 1) Distance between right and left inner pectine tooth.
Photo 2) Pectine tooth count: 28
Photo 3) Length of pectine--does not cross leg joint of 4th leg.
