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
) and anterolateral psp in Abd IV (
Fig. 33
A
) 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.
