Kay Hoover and Barbara Wilson-Clay call this a "dimpled nipple" in their 
excellent I-have-no-interest-in-it-but-you've-simply-got-to-own-it 
Breastfeeding Atlas, now in its third edition.

At pp 56-59, they write, "The dimpled nipple is a form of nipple inversion 
in which the tissue inside the fold can become adhered.  [A]dhered skin is 
very fragile compared to skin that receives a normal amount of light, air 
and friction from clothing.  When the nipple folds back on itself after BF 
or pumping, moisture is often trapped in the dimple, causing maceration.  
[I]t is important to hold the dimpled nipple in a retracted position until 
it has dried.  Applications of topical antibiotic and antifungal creams may 
be ... used to protect the skin from infection.  [O]ver time, and with 
repeated exposure to light and air, this tissue becomes less fragile, 
although good hygiene remains important in order to keep the area clean of 
debris."
