, syntype (SMF RI 291). A, dDorsal view. B, lateral view. C, panoramic dorsal view. D, original label. Scale bars: 1 mm. Photos courtesy Abel Pérez.
Diagnosis:
It differs from
P. albithorax
by having in carapace the same colour of abdomen (
Fig. 29A
) instead of yellow spots. Abdomen with slightly yellowish coloration in lateral margins (
Fig. 29A
). Tarsal counts: 7(3), 17(3)/19(3), 9, 10.
Distribution:
Only known from the
type
locality. Eastern Cordillera real montane forest ecoregion in
Zamora Chinchipe Province
of
Ecuador
(
Fig. 23
).
Remarks:
Although it was described from ‘Columbien (
Sabanilla
)’ (
Fig. 28D
), the correct place is possibly
ECUADOR
,
Zamora-Chinchipe
,
Sabanilla
. In the description of various species,
Roewer (1913
;
1923
) inconsistently cited
Sabanilla
either as being in ‘Kolumbien’ or in ‘Venezuela’.
Sabanilla
, in this case, probably refers to a small village called
Sabanilla
[–4.03333°, –79.01667°,
c
.
1500 m
], on the old road between
Loja
and Zamora (
Zamora-Chinchipe
, southern Ecuador). A subsequent record (
Roewer, 1928
) reinforces our interpretation.
Although external similarity is encountered comparing the
type
specimens of both species of
Paraprotus
(
Figs 29
,
30
),
Roewer (1912: 120)
made a detailed description of the coloration of
P. atroluteus
, remarking that dorsal scutum was mostly light rustyellow except for brown-black coloration of ocularium and ventral surface (coxae and free sternites). Then, no yellow mark is described by
Roewer (1912)
for
P. atroluteus
, which is a remarkable feature present in
P. albithorax
, described and illustrated by
Roewer (1947: 33
, pl. 12, fig. 106) and visible in
Fig. 28A.
