It can be distinguished from other congeneric species by the pattern of dry white spots occupying the anterolateral zone of the carapace, the posterior zone of the eyes, and the lateroposterior corner of the DS (Figs 11A, B, 12A, B) and by the shape and ornamentation of the leg IV of the males: femur with a subdistal dorsal group of conspicuous tubercles, patella inflated, dorsal face densely tuberculated with two large curve distal spines like horns, and tibia swollen, dorsally almost smooth, with the prolateral face densely tuberculated, with the retrolateral row with numerous contiguous large tubercles and the retrodorsal row with distal tubercles larger (Fig. 12F, G).

The species is named after Guaichía, another name given to María Lionza, a female deity belonging to Venezuelan spiritism, which originates from the state of Yaracuy, where the species inhabits. The myth of María Lionza has been interpreted as a symbol of the biological and cultural mestizaje, or intermixing, that characterizes Venezuela. It expresses the Indigenous, European, and African roots that comprise the cultural diversity of Venezuela. This is a noun in apposition.

Malleus swollen. Lamina parva (LP) almost as wide as it is long; the distal half triangular, with a well-marked neck and a circular distal cleft. MS-A1–2 located on malleus, one pair laterally and one pairs more ventrally; MS-B pair ventrally located on the truncus, supernumerary and asymmetric; two pairs of MS-C located medially on the LP, dorsally to the neck; MS-D1 and MS-D2 similar in size; MS-D1 located slightly proximal to MS-E; and MS-D2 basally located, near the base of glans; MS-E as one pair of short setae and one pair of large setae. Glans globose and wide, with a dorsally curved stylus with small triangular dorsal process. Color (Fig. 15A, B). DS background Brilliant orange yellow (67), carapace reticulated, lateral margins and spines of area III Dark orange yellow (72), abdominal scutum, and coxa I–IV dorsally Light greenish yellow (101), areas II and III with a medial zone lighter than lateral regions. Pale greenish yellow (104). Chelicerae reticulated dark olive (108) on background moderate greenish yellow (102). Legs reticulated dark grayish olive (111) on background moderate yellow green (120) to moderate greenish yellow (102).

Female. Measurements. DSL: 4.3; DSW: 3.8; AL: 2.1; AW: 3.1; IOD: 1.8; pedipalp: CoPp 0.7, TrPp 0.5, FePp 2.9, PaPp 1.4, TiPp 1.7, TaPp 1.8, ClPp 1.2, total 10.2; Leg IV: FeL 4.7, TiL 3.0. Description (Fig. 11C, D). Similar to male, except by the shape of DS, Eta (Fig. 11C), chelicerae not swollen. The mesotergal areas slightly larger in comparison to males. Basitarsus I not swollen. Legs III and IV without developed secondary sexual characteristics, only rows of granules or small tubercles. The female displays the same color pattern as the males, yet the hues are lighter in tone.

Venezuela, Yaracuy. Only known for the type locality (Fig. 2).

Eutimesius ornatus (Roewer, 1943) was described from Bogotá, Colombia (Roewer 1943), and recorded from Venezuela on a female specimen from the northeastern region of San Cristóbal in Táchira state (Pinto-da-Rocha 1997). However, this particular specimen exhibits clear discrepancies when compared to the male holotype (MCR-3862, SMFD, Pinto-da-Rocha 1997: figs 57, 58, 61, 63, 64), specifically in the pattern of white, dry spots and the size and shape of the spines in area III. While the pattern of white dry spots has displayed stability or minimal intraspecific variation in the specimens examined by us, for example, females with larger spots (Figs 5A, B, 9A, B), the pronounced aforementioned differences observed between the male and female of E. ornatus as depicted by Pinto-da-Rocha (1997), coupled with the geographical distance between both disjunct populations, raise the question regarding the identity of the female from Venezuela. E. ornatus”, Therefore, we propose that the female from Venezuela represents an undescribed species distinct from E. ornatus.

Can be distinguished from all other species of the genus by the fusion of the paired spines of scutal area III (Fig. 13).

Eutimesius spp., penis, distal portion in dorsal, ventral, and lateral view: A–C. E. aroa sp. nov., (MIZA 0105934); D–F. E. canoabo sp. nov., (MIZA 0105945); G–I. E. ephippiatus, (ICN-Ao-1492); J–L. E. guaichia sp. nov., (MIZA 0105935); M–O. E. simoni, (ICN-Ao-328). A–I. Unscaled.

Subtle variations were observed in the shape of the LP, which presents less pronounced and rounded lateral projections (instead of acute), a wider neck, and the MS-A, which are separated from each other, with one pair positioned almost ventrally and the other almost dorsally (Fig. 14M–O). Additionally, slight variations in leg coloration and the pattern of dry spots were observed in individuals potentially identified as E. simoni, which were evaluated solely through photographs of live specimens (Fig. 15). Due to these variations and limitations in the material study, we have included these records on the map (Fig. 2) as Eutimesius cf. simoni, leaving open the possibility that more than one species may be involved in the Amazonian populations.

Brazil, Amazonas; Colombia, Amazonas; Ecuador, Napo, and Los Ríos; Peru, Loreto (Fig. 15). The species was originally documented in Puerto Asis but erroneously attributed to the Department of Guainia (Pinto-da-Rocha 1997). We hereby correct this misattribution and reassign it to its accurate department, Putumayo.
