Actinopus urucui
sp. nov.
, male: A–D MPEG 22271: A. Patella III, dorsal; B. Tibia III, dorsal; C. Patella IV, dorsal; D. Tibia IV, dorsal.
Etymology.
The specific name is a noun in apposition from the
type
locality name.
Diagnosis.
Males of
Actinopus urucui
differ from
A. parafundulus
(
Fig. 162
A–C) by the leg metatarsi and tarsi paler than other articles; shorter tegulum; presence of three keels (PAc, PS and PI) on copulatory bulb; and a smaller PA (
Fig. 165
A–C).
MALE (MPEG 13206): Total length 9.38; Carapace, long 4.63; wide 3.88. Carapace rounded. Anterior eye row slightly procurved, posterior row recurved (
Fig. 163 B
). With short an weak bristles between AME-clypeus, between ALE–ALP, between posterior eyes-fovea and lateral eyes-edge of carapace. Sternum with eight sigilla fused medially, two distal sigilla more fused than others (
Fig. 163 C
). Rastellum protuberant, inverted V-shaped, hirsute, without spines apically (
Fig. 163
E–F). Chelicerae with eight denticles along prolateral row of teeth. Prolateral row with four megateeth and one basal tooth. Retrolateral row with six megateeth (
Fig. 163 D
). Patella and tibia III with distal crown of well-developed thorns, on patella III interrupted in middle and on tibia III not interrupted in middle (
Fig. 164
A–B). Patellae III and IV with spines on prolaterodorsal face (
Fig. 164 A, C
). Tibia IV without spines on dorsal surface (
Fig. 164 D
). Ventral pseudoscopulae occupying 10% of tarsus I, 40% of II and 100% of III and IV. Pseudoscopula of tarsi I and II with setae spaced, forming diffuse group of bristles; On tarsi III and IV, compact. Carapace, chelicerae, sternum, coxae, trochantera, femora, patellae, tibiae pale brown; metatarsi and tarsi of legs yellowish brown, paler than other articles; Abdomen pale gray (
Fig. 163 A
).
