426E06A02C11DFE26260EE205AD40568.taxon	diagnosis	Diagnosis. Ceratogyrus attonitifer sp. n. can be diagnosed from its congeners, and all other species of Theraphosidae, by the presence of a large, elongate protuberance which extends out of the fovea and over the spider's abdomen (Figure 2).	en	Midgley, John M., Engelbrecht, Ian (2019): New collection records for Theraphosidae (Araneae, Mygalomorphae) in Angola, with the description of a remarkable new species of Ceratogyrus.

426E06A02C11DFE26260EE205AD40568.taxon	etymology	Etymology. The specific epithet is derived from the Latin root attonit-, meaning astonishment or fascination, and the suffix - fer, bearer of or carrier, and refers to the astonishment felt by the authors at the discovery of this remarkable species.	en	Midgley, John M., Engelbrecht, Ian (2019): New collection records for Theraphosidae (Araneae, Mygalomorphae) in Angola, with the description of a remarkable new species of Ceratogyrus.

426E06A02C11DFE26260EE205AD40568.taxon	description	Description. Measurements are presented in Table 2. Carapace (Figure 3 A, B): Golden brown with paler coloration distally; ovate, hirsute with fringe of longer, pale setae on lateral and posterior margins. Cephalic region flat in lateral profile, not distinct from thoracic region. Ocular tubercle distinct with eye pattern as in Figure 4 A. Eye sizes (mm): AME: 0.3 (0.27 - 0.32), ALE: 0.46 (0.36 - 0.51), PME: 0.22 (0.18 - 0.25), PLE: 0.41 (0.38 - 0.44). ALE larger than all other eyes, ca. 1.5 x diameter of AME; PLE larger than PME, AME and PLE similar in size. Clypeus relatively wide, straight, with fringe of short, anteriorly oriented setae on anterior margin. Fovea strongly procurved with prominent, elongate protuberance extending over dorsal aspect of abdomen, as long as or longer than carapace length, anterior part extending from carapace sclerotized, remainder soft and membranous, bag-like in living specimens, becoming shrivelled when preserved, dark in colour. Chelicerae: Golden brown, hirsute on dorsal, prodorsal and anterior surfaces. Retrolateral surface concave, more so ventrally, with distinct, well developed scopula of plumose setae. Prolateral surface with fine, sparse setae, no plumose setae; ventral surface with single row of seven large teeth along promargin and single, small depression anterior to first tooth;> 10 smaller teeth or denticles on proximal ventral surface external to larger teeth. Promargin with long, slender, grey setae; retromargin with long, red, wooly setae corresponding to those on maxilla. Sternum, labium and maxillae (Figure 3 C): sternum densely hirsute with short black setae, longer setae marginally and anteriorly. Sigilla not apparent. Labium sparsely hirsute with elongate, slender setae and ca. 60 - 85 cuspules. Maxillae densely covered in 250 - 320 cuspules on proximal region of ventral surface; ventral surface also with sparse medium to long, slender setae, becoming shorter on retrolateral surface. Prolateral surface with sparse, elongate setae; proventral margin with elongate, red, woolly setae, no spiniform setae present. Legs and pedipalps: all femora golden brown dorsally; palps and legs I and II dark brown for remainder of dorsal and retrolateral surfaces; legs III and IV golden brown for remainder of dorsal surface. Palps and legs I and II dark brown to black ventrally and prolaterally as is typical for the genera Ceratogyrus and Augacephalus (Gallon 2005). Legs III and IV with alternating broad, pale and narrow dark brown bands as follows: majority of femora yellow-brown but with proximal and distal margins dark brown, patella dark brown, tibia yellow-brown. Palp and leg tarsi scopulate for entire ventral surface; all leg tarsi with paired claw tufts concealing paired tarsal claws, third claw absent, but a small triangular patch of longer scopular setae is present in its place. Metatarsi scopulate, scopulae entire for legs I-III, divided by longitudinal row of setae on leg IV. Scopulae broad and covering almost entire non-articulating surfaces of metatarsi I and II, approximately distal 3 / 4 of metatarsus III, narrow and tapering for metatarsus IV covering distal 2 / 3 of non-articulating surface. Dorsal surface of palp and leg tarsi with long, scattered setiform trichobothria and two distal submedian rows of short, clavate trichobothria. For palps and legs I, II, III, and IV counts of clavate trichobothria as follows: 6 - 21, 12 - 27, 13 - 30, 16 - 29, 15 - 29. Spination: all leg tibia with 1 DPV, 1 DRV; metatarsi III and IV with 1 DPD, 1 DRD; remaining segments without spines. Abdomen: densely hirsute with short setae and more sparse, elongate setae; dorsal and lateral surfaces brown with golden speckles. Ventrally, book lungs covered with pale, yellow-brown transverse bands, separated by narrow, black band of setae, remainder of ventral surface posterior to book lungs, and spinnerets, black. Distal segment of posterior spinnerets digitiform, but not markedly elongate. Spermathecae (Figure 4 B): Simple, paired, unlobed, flattened in cross section; relatively broad, widening at their base, no swollen terminus. Not diagnostic within the genus.	en	Midgley, John M., Engelbrecht, Ian (2019): New collection records for Theraphosidae (Araneae, Mygalomorphae) in Angola, with the description of a remarkable new species of Ceratogyrus.
