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.

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 ).

Female (IAvH-I-604). Coloration and abdominal spots patterns as male ( Fig. 60C–D ). Measurements: total length 3.26, carapace length 1.72, width 1.15, height 0.81. Clypeus height 0.35.

Epigyne: lateral borders (LB) short, curved towards posterior region of epigyne, forming posterior, small and heart-shaped atrium (A); median field plate (MFP) small inconspicuous; copulatory ducts (CD) very short, wide; seminal receptacles (SR) absent; spermathecae (S) large, bean-shaped, posteriorly positioned; fertilization ducts (FD) shorter than the spermathecae length ( Figs 61E–F ; 62C–D ).
