of tarsi III divided by a line of longitudinal setae, in tarsi IV divided by a wide band of setae.

Agnostopelma: a new genus of tarantula without a scopula
on leg IV (Araneae, Theraphosidae, Theraphosinae).
This group of genera can be recognised by several synapomorphic characters that may (once all the genera have been revised) support the monophyly of this group within Corinnidae, be it at tribal or subfamilial level: strongly spined femora I, and strong ventral leg spines on the anterior tibiae and metatarsi; procurved eye rows, posterior row nearly straight; broad male palpal cymbium with dense dorsal setal mat (= cymbial scopula
) and modified setae; male palpal tegulum with a short, fine median apophysis; and simple female genitalic structure (see Lessert 1923; Lawrence 1937, 1952; Haddad 2007).
: Metatarsi I, 1/2 distal, scopulae not dense intermixed with few bristles; tarsi I, full, division with 2-3 rows of thin bristles; metatarsi II, distal half, rudimentary, scopuliform hair intermixed with few bristles; tarsi II, full, divided with 3-4 rows of bristles; metatarsi III, 1/4 distal, few scopuliform hairs intermixed with bristles and spines; tarsi III, full, divided with 6-7 rows of setae; metatarsi IV, few scopuliform hair distally; tarsi IV, full, divided with 6-7 rows of setae.
All leg podomeres lack macrosetae; leg 1 with sparse scopula
of fine, erect setae on tibia, metatarsus, and tarsus.
Ventral face covered by thin setae and black erect setae, which get thinner towards the reddish maxillary scopula
. Anterior area with around 25 distinct cuspules.
1A); metatarsus III shorter than metatarsus I; scopula
of metatarsus III reaches to 1/2 leg length; scopula
of metatarsus IV divided by four rows of setae, reaches to 1/3 leg length; numerous long hairs on retrolateral tibia and metatarsus IV (Fig.
Raven (1985), based on Vellard's description, considered Neostothis a junior synonym of Chaco Tullgren, and transferred the genus from Barychelidae to Nemesiidae (Pycnothelinae), due to the presence of scopula
on tarsi III and IV, wide labium, and absence of third claw.
of tarsus and metatarsus I and II slightly developed.
absent; a row of 2-3 spine-like setae on mesal ventral portion of metatarsus (Fig.
Chelicerae with many long dense scopula
hairs, 3 promarginal and 2 retromarginal teeth, condyle developed laterobasally and fang slightly longer than cheliceral width (Figs.
