Ordo: Araneae
Familia: Theraphosidae
Genus: Typhochlaena
Name
Typhochlaena paschoali Bertani, 2012 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
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.

Carapace: length to width 1.0. Fovea 1.5 wide. Eyes: tubercle 0.1 high, 1.1 long, 1.8 wide. Clypeus 0.2. Anterior eye row procurved, posterior slightly recurved. Eye sizes and inter-distances: AME 0.3, ALE 0.4, PME 0.2, PLE 0.3, AME–AME 0.4, AME–ALE 0.2, AME–PME 0.2, ALE–ALE 1.3, ALE–PME 0.3, PME–PME 1.1, PME–PLE 0.1, PLE–PLE 1.5, ALE–PLE 0.3, AME–PLE 0.4. Ratio of eye group width to length 2.4. Maxillae: length to width: 1.7. Cuspules: 64 spread over ventral inner heel.

Scopula: tarsi I–III fully scopulate, IV divided by row of 6 setae. Metatarsi I–II 4/5 scopulate; III 2/3, IV 1/4 distal scopulate. IV divided by six wide row of setae. Spines: two apical spines on ventral metatarsus IV. Urticating hairs type II (0.32 to 0.4 long, 0.01 wide) on the abdomen dorsum. Genitalia: paired broad spermathecae very slightly curved outwards, ending in multilobular apex (Fig. 7). Color pattern (preserved in alcohol): carapace and chelicerae brown. Legs and palps light brown, except for tarsi and metatarsi I–III and tarsi of palp and leg IV, darker. Coxae, maxillae and labium light brown. Sternum dark brown. Longitudinal stripes on dorsum of femora, patellae, tibiae and metatarsi inconspicuous. Distal femora, patellae, tibiae and metatarsi with white rings. Abdomen black, dorsum with a central longitudinal white pattern having zigzag border. Cephalic area and chelicerae with long stiff setae. Abdomen dorsum with several scattered, very long, white guard-hairs (Fig. 27).
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).
