Scale bars = 0.5 mm. According to Cooreman (1976: 47), the typeseries of  C. leleupicomprised four juveniles, but only three were found in the vial of specimens listed as types. A second vial containing another juvenile, with slightly different collection data from the original description, is assumed to be the fourth typespecimen.  DIAGNOSIS:  Cryptocellus leleupiclosely resembles  C. chiruislaand  C. guaviarensis, with which it shares several morphological characters of the male: a pronounced median elevation and distinct, granular triangular surface of the cucullus; a wide movable finger of the chelicera; a well-developed ventral notch, ventral subbasal protrusion, and proventral distal expansion of the tibia of leg I; the metatarsus of leg I compressed prolaterally in proximal two thirds, with a distinct distal expansion ventrally; and a tuft of long setae ventrodistally on the metatarsus of leg III. The male of  C. leleupiis most similar to that of  C. chiruislain the tibia of leg I, notably the subbasal protrusion situated proventrally in the proximal half of the segment, and the short ventral notch, visible in dorsal and prolateral aspects. The two species also resemble each other in the subapically truncated retrolateral margin of the cheliceral movable finger and in the similar shape of the fixed process of the male copulatory apparatus. The male of  C. leleupidiffers from the males of  C. chiruislaand  C. guaviarensisin the absence of a retroventral distal expansion of the tibia of leg I that, although small, is present in the other two species and in the anterior triangular surface of the cucullus, which is slightly concave in  C. leleupi, but planar in the other species. Additionally, the posterodorsal margin of the basal segment of the pygidium is notched in  C. leleupiand  C. chiruisla. This notch is deep, with the ventral margin distinctly notched, in the female of  C. leleupi(fig. 16D) (both are shallow in the male); in contrast, the pygidium is more shallowly notched dorsally, whereas the ventral margin is entire, in the female (and male) of  C. chiruisla. Furthermore, the posterior genital lip is acute in the female of  C. leleupi(fig. 19C) but trilobate in the female of  C. chiruisla, and the spermathecal morphology also differs slightly in the two species.  MALE: The only male that has hitherto been located (UFMG 9099) is currently mislaid (see Remarks). DESCRIPTION OF FEMALE: Based on the female from Estación Biológica Jatun Sacha (MACN Ar 37274).  Measurements:Total length, 4.26 mm(table 1).  FIGURE 18. A–D.  Cryptocellus islacolon, sp. nov., holotype ♂ (OUMNH 2010-028-001) and E–H.  Cryptocellus goodnightiPlatnick and Shadab, 1981, holotype ♂ (AMNH IZC 324859), leg III copulatory apparatus, prolateral aspect ( A, E), dorsal aspect ( B, F), dorsal aspect, inclined ( C, G), and ventral aspect, inclined ( D, H).

Pair of small papillate vesicles situated submedially on posterior surface, aligned with base of spermathecae (fig. 19C).   DISTRIBUTION:  Cryptocellus leleupihas been recorded from the Jatun Sacha Biological Stationand the Río Negro, respectively situated in the Napoand Tungurahuaprovinces of Ecuador(fig. 1).  REMARKS:  Cryptocellus leleupiwas described from a juvenile specimen which, based on the number of tarsomeres on the walking legs (I:1, II:4, III:3, IV:2), can be recognized as a protonymph. The typeseries consists entirely of juveniles, thus failing to provide information concerning the adult morphology necessary for species diagnosis and was therefore considered a nomen dubium by Platnick and Paz (1979). No other published records of ricinuleids occur in the immediate proximity of the typelocality of  C. leleupi, Río Negro, situated in the eastern foothills of the Ecuadorian Andes. However, a juvenile identified as  Cryptocelluscf. leleupi, from the Jatun Sacha Biological Station, situated ca. 73 kmnortheast of the typelocality, was included in a molecular study by Fernández and Giribet (2015). The taxonomic identification of the cytochrome oxidase csubunit I DNA sequence (GenBank accession KR180410) is listed as  C. leleupialthough the voucher (IZ-130032) is listed as  Cryptocellussp.in MCZbase, the database of the Zoological Collections (https://mczbase.mcz.harvard.edu/SpecimenSearch.cfm). A male and a female from the Jatun Sacha Biological Station were examined during the present investigation and confirmed to differ from all other ricinuleid species. Given the relative proximity of this station to the typelocality of  C. leleupi, it seems reasonable to consider these specimens to be conspecific. The male (UFMG 9099) was examined in December 2017, when the species diagnosis was prepared. Soon after, the vial with the specimen was mislaid in UFMG and, despite extensive searches, has not been located, preventing a more detailed and thorough documentation of the male morphology. Nevertheless, the diagnosis presented herein is sufficient to permit recognition of the species. The structures noted in the diagnosis have been well documented in the description of the two other  Cryptocellusspeciesto which  C. leleupiis compared (Botero- Trujillo and Flórez, 2017). Although knowledge of the adult morphology of  C. leleupiremains incomplete, it is now possible to recognize this species. Therefore,  C. leleupiis no longer considered a nomen dubium.    MATERIALEXAMINED:  ECUADOR:  Napo: Cantón Tena, Parroquia Puerto Napo, Estación Biológica Jatun Sacha, 01°03′57.5″S 77°37′0.2″W,  410 m,  1–5.xii.2009, C.
