Etymology. The species is named after the Betica Region (approximately corresponds to modern Andalucia) where it hasAbout 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‒ AbdAbout Abd II, AbdAbout 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 macAbout mac (4 in S. dagamae  ) and PmA and PmC groups with 7‒9 and 6 macAbout mac, respectively (7 and 5 in S. dagamae  ); Th III with 7‒9 macAbout mac inner to pspAbout psp (6 in S. dagamae  ); and AbdAbout Abd IV with macAbout 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 notAbout 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 notAbout not be used to compare the species. The presence of a subapical rounded bulb on AntAbout Ant III ( Fig. 31 A View Figure ) and anterolateral pspAbout psp in AbdAbout Abd IV ( Fig. 33 A View Figure ) of S. betica  sp. nov. are exclusive features registered here forAbout 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.
