Resumen:
A new ricinuleid species, Cryptocellus chimaera sp. nov., is described
based on a male specimen from Northwest Ecuador (Esmeraldas, Reserva
Ecologica Mache-Chindul, Estacion Biologica Bilsa). This species is
unique among all Cryptocellus in having very large longitudinal
carapacial translucent areas together with a markedly incrassate femur
of leg II. Representing only the second species of the order described
from Ecuador, C. chimaera sp. nov. is assigned to the magnus
species-group of Cryptocellus Westwood, 1874. Cryptocellus chimaera sp.
nov. is remarkable, for its morphology resembles that of Cryptocellus
magnus Ewing, 1929, especially with regard to the male copulatory
apparatus, although both resemble Pseudocellus Platnick, 1980, due to
the presence of diffuse longitudinal carapacial translucent areas. Along
with the new species description, a comparative diagnosis and
supplementary images are provided for C. magnus. Based on direct
observations of some species belonging to the five species-groups of
Cryptocellus, we discuss on the occurrence of different morphologies of
carapacial translucent areas within the genus. We deem it important to
continue the survey of morphological characters, especially within
Cryptocellus, in order to increase our understanding of the
species-groups and to unravel their relationships.
