Agathidium microphthalmum Subgroup

DISCUSSION: This species subgroup is unit­ ed by small body size, the very strongly reduced eyes, the large male metafemoral tooth, and distribution in southern Mexico and Guatemala. The three species are externally fairly similar but may be distinguished by the small size and shape of the eyes (figs. 110–112) and by the shape of the male genitalia with the median lobe lacking lateral carinae and sulci and the lateral lobes apically straight (figs. 335–343).
