Lyssomanes mexicanus Logunov, 2014: 65 , figs. 37-39 (male holotype from Mexico, Veracruz, about 7 km N of Huatusco , deposited in MCZ, not examined); World Spider Catalog, 2020 .

Material examined. MEXICO, Veracruz: Xamaticpac de Calcahualco , 19.1261°N, 97.0670°W, 1700 m, 15- 24 Feb 2013, 2 males and 2 females, U . Garcilazo-Cruz, CNAN 10186-10189 .

Diagnosis. Males of L. mexicanus are close to those of L. anchicaya Galiano, 1984 and L. taczanowski Galiano, 1980 , but they can be distinguished from both by the thicker embolus with large obtuse basal outgrowth (absent in the other two species), and the shape of median apophysis ( Figures 12-15 ). On the other hand, females are similar to those of the L. elegans F. O. Pickard-Cambridge, 1900 and L. michae Brignoli, 1984 , for their rounded spermathecae, and copulatory openings (co) lateral and anteriorly located. From these species, the females of L. mexicanus can be differentiated by their longer copulatory ducts (cd), more distally located glandular ducts (arrow in Figure 18 ) and anterior and internally located fertilization ducts (fd) ( Figures 16-18 ).

Description. Female (CNAN 10186, figs. 10-11, 16-18). Total length: 6.91. Carapace length: 2.59, width: 2.23, height: 0.92. Carapace high, rounded and yellowish (Figures 10-11). OC: 1.29, with some dispersed orange hairs. Width of eye rows, first: 1.24; second: 1.23; third: 0.80; fourth: 0.90. Diameter AME: 0.58; ALE: 0.26; PME: 0.04; PLE: 0.23. Clypeus low (0.14 height). Chelicera length: 0.98, yellowish, vertical, with six retromarginal and two promarginal teeth. Sternum length: 1.24; width: 1.17, white. Labium length: 0.39; width: 0.31, yellowish. Thoracic groove 0.41 long. Legs I-II stronger than III-IV, all yellowish. Legs I II IV III. Leg segments, I: 2.85+1.23+2.58+2.51+0.60; II: 2.37+1.03+2.08+2.03+0.61; IIII: 2.30+0.80+1.91+1.95+0.69; IV: 2.43+0.78+1.86+2.35+0.50. Leg macrosetae: Femur I-III d 2 di, p 0-1-1, r 1 me; IV d 2 di, p 1 di. Tibia I v 2-2-2-2, p 1 di, r 1 di; II v 2-2-2-2, p 0-1-1-0, r 0-0-1-0, d 0-0-1-0; III v 2-0- 2-0, p 0-1-1-0, r 0-0-1-0, d 1-0-1-0; IV v 1-0-2-0, p 0-1-1, r 0-1-1, 1-0-1. Metatarsus I-II v 2-2-2, p 1 pr, r 1 pr; III-IV v 2-2-1, p 1 pr, r 1 pr. Abdomen cylindrical and yellowish, with two pair of brown spots, dorsal and laterally located (Figures 10-11), 4.32 long, 1.67 wide. Epigyne ( Figures 16-18 ): epigynal plate small, weakly sclerotized, with a posterior straight border; two rounded and small anterior and lateral copulatory openings; relatively short copulatory ducts, and rounded median spermathecae, with posterior and internal fertilization ducts (fd).

Variation. (n=2) Total length: 6.48-6.91, carapace length: 3.99. The other female examined presented more abundant orange hairs in the OC. On the other hand, males (n=2) total length: 5.96-7.00, caparace length: 2.36-2.85, presented a more slender and less wide embolar base (arrow in Figure 14 ).

Distribution and Comments. Mexico ( World Spider Catalog, 2020) ( Figure 19 ). This species appear to be endemic to Mexico, from the southeastern state of Veracruz ( Logunov, 2014). Here, a new southwestern and altitudinal record of the species is presented, in the state of Veracruz. In the Arachnological Collection of the Facultad de Ciencias of the Universidad Nacional Auto7noma de Me7xico (CAFC, F. AVlvarez-Padilla) the author examined another 46 specimens of this species, with the same data as presented above in the examined material, two of which were females and one juvenile. This material cannot be put in material examined because it is in process to be donated to CNAN. This species has been collected by beating low vegetation, and by hand, during the daytime in mountain ecosystems. Known altitudinal distribution: 1148-1700 m.
