Diagnosis.
Males of
Tenedos persulcatus
Jocqué & Baert, 2002
, resemble those of
T. neitai
sp. n.
by general shaped and organization of the palpal structures (
Figs 58A–D
;
59A–B
;
61A–D
;
62A–B
), but are distinguished of the remain species by having very long and thin retrolateral tibial apophysis (RTA) with a groove along of its extension, with modified base, conductor (C) ending as strongly sclerotized appendix without other projections; long and membranous median apophysis (MA) (see
Jocqué & Baert, 2002: 113
, fig. 31 A–C; figs 58A–D; 59A–B). Females can be recognized by very long and coiled seminal receptacles on small spermathecae (
Figs 58E–F
;
59C–D
).
Remark.
It was not possible to examine the
type
material of this species. The specimens herein referred were collected in
Norte de Santander department
and compared with the original illustrations made by
Jocqué & Baert (2002)
. Otherwise, the female was collected together with males and their abdominal spots patterns are similar, allowing us to deduce their co-specificity. Males and females of this species presents remarkably differences on genital morphology, which are unusual in the remaining species of
barronus
group, however, due scare additional morphological evidence these species are provisionally placed in this group.
Description.
Male
(ICN-Ar-12314). Coloration (
Fig. 57A–B
): carapace brown-reddish, light on medial region. Chelicerae with paturon brown, fangs brown-reddish. Endites light brown, white on anterior region. Labium and sternum brown. Legs: Coxae I–IV light yellow. Femora I–IV brown with some dark lateral spots. Patellae-Tarsi I–IV brown. Abdomen: dorsally dark gray with nine white guanine spots organized as follows: two sub-oval spots, anteriorly positioned; four sub-oval spots larger than previous ones, medially interrupted by two transversal and elongated spots, all medially positioned; a large transversal spot, posteriorly positioned. Laterally dark gray with a wide and oblique longitudinal stripe, extending to the posterior side. Ventrally light gray with three large and wide stripes, being the lateral largest. Spinnerets light brown. Measurements: total length 4.27, carapace length 2.09, width 1.35, height 0.85. Clypeus height 0.38. Eye diameters and interdistances: AME 0.07, ALE 0.08, PME 0.09, PLE 0.09; AME–AME 0.15, AME–ALE 0.17, AME–PME 0.23, PME–PME 0.20, PME–PLE 0.28, ALE–PLE 0.23. Chelicerae 0.63 length. Sternum length 0.85, width 0.84. Legs: I—femur 1.25/ patella 0.43/ tibia 1.08/ metatarsus 1.01/ tarsus 0.85/ total 6.31; II—1.07/ 0.47/ 0.87/ 0.86/ 0.68/ 5.34; III—0.99/ 0.41/ 0.79/ 0.93/ 0.66/ 5.51; IV—1.28/ 0.53/ 1.21/ 1.36/ 0.92/ 7.38. Abdomen length 1.90. Legs spines pattern (only the differences from the general pattern): I—tibia v1r-1r-1p; II—v=I, p0-1-1, metatarsus 1r-0-2. Palp: retrolateral process of cymbium (RPC) long, very wide; tegulum (T) large, wider than long; subtegulum (St) large, longer than wide; conductor (C) developed, flattened with short sclerotized region on distal side; appendix (ApC) short, flattened, apically squared; embolus (E) long, filiform towards apex; base of embolus (EB) approximately as long as basal tegular membrane; basal tegular membrane (BTM) originated proximally on tegulum, proximally flattened, filiform appendix; spermatic ducts (SD) S-shaped with both folds full open and thin; ventral tibial apophysis (VTA) very small; median apophysis (MA) small, membranous with sclerotized tip; retrolateral tibial apophysis (RTA) longer than palpal tibia, very thin towards distal side with modifications at base (

;
59A–B
).
Female
(ICN-Ar-8010). Coloration (
Fig. 57C–D

Legs: Coxae I–IV light yellow. Femora-metatarsi I-IV yellow. Tarsi I–IV light brown. Abdomen: dorsally dark gray with five white guanine spots organized as follows: two large and irregular spots, anteromedially positioned; two sub-oval spots smaller than previous ones, medially positioned; a large transversal spot, posteriorly positioned. Laterally dark gray with several small light spots. Ventrally, light yellow without spots. Spinnerets with basal article white, distally light brown.
