Etymology. The species is named after the Betica Region (approximately corresponds to modern Andalucia) where it has been found.

Remarks. Seira betica sp. nov. resembles S. dagamae Dallai, 1973 and S. stachi Loksa, 1990 by color pattern of body on two longitudinal white bands on Th II‒Abd II, Abd IV with irregular transverse spots, and most dorsal macrochaetotaxy pattern (at least of S. dagamae ). However, S. betica sp. nov. differs from S. dagamae by Th II with 5 medio-central mac (4 in S. dagamae ) and PmA and PmC groups with 7‒9 and 6 mac, respectively (7 and 5 in S. dagamae ); Th III with 7‒9 mac inner to psp (6 in S. dagamae ); and Abd IV with mac B1‒2 (absent in S. dagamae ). Seira betica sp. nov. differs at this time from S. stachi more clearly by unguiculus outer edge serrated (smooth in S. stachi ). The original description of S. stachi does not present the dorsal macrochaetotaxy, as well as several other characteristics, which makes difficult to compare the species (see Loksa 1990: 274). In addition, in the description of unguis 3 internal teeth are reported (proximal, median and apical), probably wrongly, since the proximal tooth is always paired in Seira (Christiansen & Bellinger 2000; Barra 2004 a, 2004b; Bellini et al. 2010; Cipola et al. 2014 a, 2014b; Godeiro & Bellini 2014, 2015), therefore this can not be used to compare the species. The presence of a subapical rounded bulb on Ant III ( Fig. 31 A View FIGURE 31 ) and anterolateral psp in Abd IV ( Fig. 33 A View FIGURE 33 ) of S. betica sp. nov. are exclusive features registered here for the first time in Seira , which can help distinguish this species from other related taxa. Other comparisons among species are presented in Tables 1 and 2.
