Etymology. The specific epithet is a patronymic in honor of the entomologist Jhon Cesar Neita by his many contributions to the taxonomy and systematic of the Scarabaeoidea in Colombia.
Diagnosis. Tenedos neitai sp. n. is similar to T. persulcatus Jocqué & Baert, 2002 by long anterior branch of retrolateral tibial apophysis (aRTA), cymbium narrow towards apical side and by basal retrolateral tibial apophysis (bRTA), but can be distinguished by having very thin anterior branch of retrolateral tibial apophysis (aRTA); conductor (C) with several very short and strongly sclerotized extensions, heart-shaped atrium (A), bean-shaped spermathecae (S) (Figs 61A–F; 62A–D).
Remark. Like T. persulcatus, males and females of this species presents remarkably differences on genital morphology, we provisionally placed it in barronus group.
Description. Male (IAvH-I-592). Coloration (Fig. 60A–B): carapace uniformly reddish-brown. Chelicerae with paturon brown, fangs brown-reddish. Endites light brown, white on anterior region. Labium and sternum brown. Legs: Coxae-tarsi I–IV light brown, except tibia and metatarsus I, pale yellow. Abdomen: dorsally dark gray with eleven white guanine spots organized as follows: two longitudinal and wide spots, with an internal notch, anteriorly positioned; two small and irregulars spots, sub-medially positioned; six small and irregular spots dispositioned in groups of three, medially positioned; a transversal and wide band, posteriorly positioned. Laterally dark gray with a large and wide spot, posteriorly positioned. Ventrally totally covered by a large spot. Spinnerets light brown.

Palp: retrolateral process of cymbium (RPC) long and wide, with small process on medial region; tegulum (T) small; subtegulum (St) longer than wide in ventral view; conductor (C) developed, flattened on distal region, with short and wide sclerotized region on distal side; appendix (ApC) short, flattened, apically squared, with small projections; embolus (E) long very wide at base, filiform towards apex; base of embolus (EB) approximately as long as three times as basal tegular membrane; basal tegular membrane (BTM) originated basally on tegulum, ligule-shaped; spermatic ducts (SD) S-shaped with both folds full open and thin; ventral tibial apophysis (VTA) very short; median apophysis (MA) small, membranous; anterior branch of retrolateral tibial apophysis (aRTA) longer than palpal tibia, posterior branch (pRTA) laminar and short (Figs 61A–D; 62A–B).
