Medrano, Miguel & Kury, Adriano B., 2017, Taxonomic revision of the Andean genus Eulibitia Roewer, 1912 (Arachnida, Opiliones, Cosmetidae), with the description of five new species, European Journal of Taxonomy 357, pp. 1-55: 12-16
treatment provided by
Eulibitia clytemnestra sp. nov.
Paramedian tubercles of posterior margin of scutum rounded and contiguous, other areas finely granulated, without tubercles ( Fig. 9AView Fig). Ladder mask only present in area II, entering only a little into scutal grooves ( Fig. 8AView Fig). Differs from other species of the genus because of the smooth lateral margins ( Fig. 9 AView Fig). Coda very short and mid-bulge asymmetrical, coxa IV slightly granulated, without clavi inguines ( Figs 8 AView Fig, 9 AView Fig). Femur IV straight, without conspicuous ornamentation ( Figs 8D, FView Fig, 10View Fig A–C).
Noun in apposition from Clytemnestra, daughter of Leda and sister of Helen of Troy, from Greek mythology. Two of the new species of Eulibitia have been named after Helen and Clytemnestra to complete the four siblings originating from the union of Zeus and Leda.

MEASUREMENTS. CL = 2.52, AL = 4.29, CW = 3.71, AW = 6.05, Fe IV = 6.67, Ti IV = 5.54.
DORSUM ( Figs 8View Fig, 9 AView Fig). Dorsal scutum beta-shaped, with asymmetrical mid-bulge. Posterior margin of scutum with two paramedian rounded tubercles. Lateral margins of scutum smooth. Posterior margin
of scutum with row of small tubercles. Tergites with row of small tubercles and anal operculum finely granular.
VENTER ( Fig. 8 C, EView Fig). Free sternites finely granular; coxae II–IV finely and uniformly granular; coxa I with longitudinal row of tubercles and smooth area corresponding to locking area of Pp Tr.
CHELICERAE ( Fig. 10 FView Fig). Basichelicerite with minute tubercles on ecto-basal side and two on antero-mesal corner; movable finger with row of tubercles, giving a serrated appearance, and large basal tubercle; fixed finger with five tubercles decreasing in size from basal to distal part of finger.
PEDIPALPS ( Fig. 10View Fig D–E). Trochanter with strong ventral process. Femur with pronounced dorsal row of seven tubercles, with ventral row of ten setiferous tubercles and mesodistal process. Patella with low mesal keel.
LEGS ( Figs 8 FView Fig, 10View Fig A–C, G). Coxa IV finely granulated, without clavi inguines, distal apophysis of coxa IV slightly tuberculate and directed laterally. Trochanter IV with small retro-distal apophysis. Femur IV straight, with two longitudinal ventral rows of small tubercles along entire length. Patella IV substraight, with small tubercles. Tarsal counts: 6(3)/12–11(3)/7–?/8.
COLOR ( Fig. 8View Fig). Body and appendages color background 68 (Strong Orange Yellow), ladder mask 104 (Pale Greenish Yellow). Trochanter and tarsomeres 98 (Brilliant Greenish Yellow).
GENITALIA ( Fig. 9View Fig B–C). Ventral plate subrectangular, narrower basally and distal border hardly concave; dorsal apophysis of glans long and rounded, wattle long. Shapes and organization of macrosetae as follows: MS C 1– C 2 large, curved and flat; MS D1–D2 large and straight, D2 smaller than D1 and located closer to MS A 1; MS A 1– A 2 large, cylindrical, straight, located in basal middle of ventral plate (asymmetry in number of MS A already seen in E. maculata ); MS B and MS E 1– E 2 ventral, very small and immersed in microsetae. Pair of MS B at base of ventral plate.
Only known from the type locality, in the WWF ecoregion Magdalena Valley montane forests ( NT 0136), tropical and subtropical moist broadleaf forest biome, in Santander Department ( Fig. 33View Fig).
