Trichopterna cucurbitina (Simon, 1881)

( Figs 118–124)

Erigonopterna alticeps Denis, 1951: 150 , figs 1–6. New synonymy.

Remarks: The excellent figures of Erigonopterna alticeps Denis, 1951 , with typical cephalic tubercle and tibial apophysis allow a positive identification as Trichopterna cucurbitina (Simon 1881) . The former becomes its junior synonym. Denis statement “à un examen superficielle, cette Araignée peut être confondue avec Trichopterna thorelli (Westring,)” also is confirm to the synonymy.

Palp ( Figs 120–122): Tibia with large, triangular, retrolateral apophysis; protegulum strongly protruding; embolic division elongated, with spiral, gently narrowing embolus.

Epigynum ( Fig. 123): With two slightly converging lateral grooves and two anteromedian, strongly chitinised lobes.Vulva ( Fig. 124): Spermathecae oblique oval, with some additional lobes, touching in the middle; insemination ducts originating near anteromedian lobes, leading laterally to spermathecae.

Previous records: Porto: Freixo, river bank of Douro ( Machado 1949) . Viana do Castelo: Vila Nova de Cerveira, Ilha dos Amores ( Machado 1949); Paredes de Coura, Mantelães ( Machado 1949).
