The number of preapical spines varies considerably intraspecifically and variability increases as a function of the number of spines. Species typically have ranges as follows: 0-2,1-3, 2-4, 3-6, 4-7, 6-11. Apical spines on hind tibia (Fig. 3f) This includes all spines on the hind tibia, though rarely some may be remote from the apex. These spines are present in members of all agathidine genera. Members of the genus Pharpa have between five and seven spines and this is also the most common range in the Agathis group of genera. In Alabagrus the number of spines varies from three to 20. As with mid tibia preapical spines, there is some intraspecific variation in this character. The number of spines on the hind tibia is positively correlated with the number on the mid tibia. Sculpture of the hind leg ventrally (Figs 3a, b, c, e) There are three states of this character in Alabagrus: smooth with scattered weak punctures (Figs 3b, e), strongly punctate (Fig. 3a), and rugose (Fig. 3c). The first is considered the primitive state, is the only one occurring in the sister group Pharpa and is the most widespread in the Agathidinae. The other two states occur in other Agathidine genera but not commonly. These states occur convergently and sporadically in Cremnops and allies, and in Zelomorpha and allies, both of which are distantly related to Alabagrus. Dimensions of hind femur (length/width) (Fig. 3e) The hind femur varies in size from 2-7-5T x longer than wide in Alabagrus. Members of Pharpa have hind femora varying from 3-5-4-3 x longer than wide and the vast majority of agathidines in the Agathis group fall in this range. There is some i
