The front row is recurved, with the two middle eyes ( anterior median eyes ) further in front than the two at the sides ( anterior lateral eyes ).

The back row is procurved, with the two middle eyes ( posterior median eyes ) further in the back than the two at the sides ( posterior lateral eyes ).
23.
In addition, the posterior median eyes are close to the anterior lateral eyes, while they are midway between the anterior lateral eyes and posterior lateral eyes in related genera.
24.
Most diagnostic are the front row of four eyes, in which the anterior median pair are more dramatically prominent than any other spider eyes apart from the posterior median eyes of the Deinopidae.
25.
The posterior median eyes ( PME ) are vestigial in many species, but in some primitive sub-families they are comparable in size with the other secondary eyes and help to detect motion.
26.
The median eye, or the naupliar eye, is situated anteriorly in the centre of the head and is the only functional optical sense organ in the nauplii, which is functional until the adult stage.
27.
They can be readily distinguished from other genera in the subfamily by their anterior median eyes being larger than the anterior lateral eyes, whereas in other genera the reverse is true, along with a number of more technical reproductive features.
28.
It can still be changed quite easily, so please be brutal if necessary LOL . Details ( median eyes, pustules and scales on tergites, ornamentation on epimera, clearer delineation between carapace and compound eyes, etc . ) will be done after the basic body shape is approved.

Schmidt differentiated " Chromatopelma " from " Aphonopelma " based on the scopulae of the tarsus of the third leg and the metatarsus and tarsus of the fourth leg being divided by bristles ( setae ); the very large posterior median eyes; and the single fused spermatheca of the female.

Ashley Montagu said that the San have the following neotenous traits relative to Caucasoids : large brain, light skin pigment, less hairy, round-headed, bulging forehead, small cranial sinuses, flat roof of the nose, small face, small mastoid processes, wide eye separation, median eye fold, short stature and horizontal penis.
