Typhochlaena paschoali sp. n. Figs 7, 27-28

Diagnosis.

The females differ from those of all other Typochlaena spp. by an almost straight, broad and short spermathecae, with a multilobular distal portion (Fig. 7). Male unknown. Additionally, females have cephalothorax and legs brown, abdomen black with dorsum with a central longitudinal white pattern having zigzag border (Fig. 27).

Etymology.

The specific name is a patronym in honour of Elbano Paschoal de Figueiredo Moraes, a Brazilian environmentalist who was died early on April 2011. He was one of the founders of the NGO "GAMBA - Grupo Ambientalista da Bahia", and was well known for his efforts in preserving Brazilian Atlantic rainforest remnants in the state of Bahia, Brazil.

Distribution.

Known from southern state of Bahia, Brazil. A single record for Tapera, in the state of Pernambuco, Brazil is probably a label mistake (Fig. 28).
