Iberina montana is a small spider with a body length of 1.4–2 mm. The
palps on the male have 3 black bristles on the outer side of femur which break off easily, although the base is always still visible. The vulva has a small, median
spermatheca with the distance between the primary spermathecae smaller than their width. The
prosoma is yellowish, suffused with black, while the
opisthosoma is dark with vague chevrons. Its body is quite densely covered with long pale hairs. The legs are yellow-brown with relatively strong spines. ==Biology==
