Etymology.
The specific name is a patronym in honor of Evert Irving Schlinger, who collected the
type
specimen.
Diagnosis.
The female of
Tinus schlingeri
sp. nov.
resembles those of
T. palictlus
Carico, 1976
by the long lateral lobes (LL) (
Carico, 1976: 76, figs. 28, 29
), but can be distinguished by the large and elongated scape-like projection of the middle field (MF) (
Fig. 4
).

Abdomen, 10.64 long, dark gray, bristly, anterior portion of dorsum with grouped dark brown bristles (
Fig. 2
). Venter light brown, scattered setae. Epigynum with large, wide and projected middle field (MF) (
Fig. 4
) and enlarged lateral lobes (LL) (
Fig. 4
). Spermathecae (S) short and rounded (

Note.
Tinus schlingeri
sp. nov.
was initially thought to be the female of
Tinus oaxaca
Carico, 2008
as both species were similar in size and colour pattern. However, close examination of the
holotype
of
T. oaxaca
revealed distinct differences in the colour pattern of carapace and abdomen. In the original description of
T. oaxaca
, the dorsal prosoma presents an uniformly brown median band (
Carico 2008
), whereas
T. schlingeri
sp. nov.
has a lighter and vivid pattern. Also, the dorsal femora and patellae of
T. oaxaca
have an “indistinct pattern” (
Carico 2008
), but
T. schlingeri
sp. nov.
presents distinct dark patches.
Also, the only known specimen of
T. oaxaca
was collected from
Oaxaca
,
Mexico
, which is about
470 km
from where
T
.
schlingeri
sp. nov.
was collected and in a different drainage basin (
Fig. 1
).
