Agnosthaetus thayerae View in CoL species-group

This probably monophyletic species-group is created for A. thayerae and A. newtoni ( Fig. 8 View Figs ), two of the more distinctive species of the subfamily Euaesthetinae . They can be distinguished from all other species of Agnosthaetus by the combination of distinct microsculpture on the head and thorax, sublongitudinal ridge of head ( Fig. 10 View Figs , sr) distinct but somewhat confused by adjacent minor carinae and punctures, deep, distinct, and dense dorsal punctation of the head (with punctures subadjacent or separated by <0.5X puncture diameter; cf. the truncatus species-group, with which these two species are most similar), and two lateral elytral ridges (as in Fig. 88 View Figs , ek, mr). Both species share many other characters, including the uniquely angulate sides of the labium (rather than the typically rounded sides: Fig. 19 View Figs ), distinctly rimmed median orifice of the median lobe ( Figs. 168 View Figs , 170 View Figs , arrows), and parameres almost entirely fused to the median lobe ( Figs. 167 View Figs , 169 View Figs ). Males of both species uniquely share the apical labral edge toothed only laterally ( Figs. 165–166 View Figs ) and each mandible with two teeth on the mesal edge instead of the usual one ( Fig. 189 View Figs , arrow: as far as I know, a unique character within Euaesthetinae ).
