Remarks. Seira pini  is most similar to S. squamoornata (Scherbakov, 1898)  , S. saxatilis Gisin & Gama, 1962  and S. lusitanica Gama, 1964  by dense macrochaetotaxy of head with macAbout mac M 4i, S4, Pa4 present, Th II with about 10 medio-central macAbout mac (m1‒2 complex) and PmA and PmC groups with 11‒13 and 10‒13 macAbout mac, respectively; and Th III ‒ AbdAbout Abd IV with at least 16, 9, 5, 1 and 16 central macAbout mac, respectively ( Tab. 2). However, S. pini  differs from these species by head with macAbout mac Pp6 present ( absent in other species), Th II with up to 13 medio-central macAbout mac (10 in S. squamoornata  and S. lusitanica  , 11 in S. saxatilis  ) and PmA and PmC groups with up to 14 and 13 macAbout mac respectively (12 or less PmA macAbout mac in S. squamoornata  and S. lusitanica  , and less than PmC 11 macAbout mac in others species); Th III with 16‒18 central macAbout mac (15 in S. saxatilis  , 24 in S. lusitanica  ), and AbdAbout Abd IV with up to 17 central macAbout mac (16 in S. lusitanica  and S. saxatilis  ). Other comparisons among species are presented in Tables 1 and 2.

Seira pini  may have different color patterns in populations ( Figs 2E‒G View Figure ). Specimens of Monegros (Zaragoza) are similar to the species of the type locality, except for the pigmentation of the trochanters and femora and the dorsal rearrangement that extends until Abd III. Species from this same population mayAbout may still have total dorsal depigmentation of Th II to AbdAbout Abd III, and partially of AbdAbout Abd IV, remaining in the latter case a central spot of dark pigment  .
