Genus Vittatus gen. n.
Vittatus fencha sp. n.
The generic name is an arbitrary combination of letters. Gender is masculine.
It is easily distinguished from other erigonine genera by its ribbon-like convector, its droplet-shaped cymbium and its prominent anterior radical apophysis (Figs 108A, 111B). The epigyne in this genus has a wide atrium and a scapoid.
Small sized Erigoninae . Carapace brown, modified in male (with small hump around PME and short sulci). Chelicerae with 5 promarginal and 4 retromarginal teeth in male, and with 5 promarginal and 5 retromarginal teeth in female. Chaetotaxy: tibial spine formula: 2-2-1-1. TmI ca 0.61, TmIV ca 0.61.
Male palp: tibia with trichobothria (prolateral and dorsal) and 2 apophyses: prolateral apophyses tongue-shaped, located near tibial base; dorsal apophysis, with a cup-like stem, and a petal-like extension around the upper-rim of the stem, bending downward (Figs 108B, 111B), Cymbium droplet-shaped (subtriangular) with elongate tip. Paracymbium ‘C’ -shaped, broad at base (Fig. 108B). Tegulum small, with protegulum protruding ventrally (Fig. 108B). Anterior radical process bifurcate, with sharp tips (Fig. 111B); convector ribbon-like, with a tapering tip (Figs 108B, 111A); embolus long and sinuous, with a small thumb near embolus tip (Fig. 108 C–D).
Epigyne: ventral fig mesally concave, with a scapoid (Fig. 110A); copulatory ducts simple (Fig. 110C); spermathecae dewdrop-shaped (Fig. 110C).
