Philoponella duopunctata View in CoL new species

( Figs. 1D–G View FIGURE 1 A – G. A – B , 4A–G View FIGURE 4 A – G , 6C–F View FIGURE 6 A – F , 7A View FIGURE 7 A – C )

Types. Male holotype (UFMG 12264) from Brazil, Acre: Senador Guiomard (Fazenda Experimental Catuaba, 10°5’30”S 67°37’54”W, 214 m), 6–16 July 2012, P.R. Zanoli & I.A. Barros leg. Female paratype (UFMG 12261) from the same locality, 9–18 April 2012, P.R. Zanoli & I.A. Barros leg.

Etymology. The specific name refers to two characteristic ventral black spots on the abdomen of this species.

Diagnosis. Males of Philoponella duopunctata can be distinguished from all other tropical American Philoponella species by the presence of a retrolateral process at the median hematodocha ( Fig. 4A View FIGURE 4 A – G ). Females can be recognized by the posterior insertion of copulatory duct in spermathecae and the large base of spermathecae ( Fig. 4E View FIGURE 4 A – G ). Males and females differ from other Philoponella by the presence of a ventral black spot on the spinnerets and other on the epigastric plate ( Fig.1 E, G View FIGURE 1 A – G. A – B ).

Description. Male (holotype). Total length 2.29, carapace length 0.99, sternum length 0.51, abdomen length 1.30; leg I, length of articles: femur 1.02, patella 0.20, tibia 0.92, metatarsus 0.94, tarsus 0.66. Length of tibia II 0.41, III 0.28, IV 0.56. Carapace pale-yellow, ocular area black ( Fig. 1D View FIGURE 1 A – G. A – B ). Chelicerae pale-yellow. Endites and labium black, sternum gray ( Fig. 1E View FIGURE 1 A – G. A – B ). Legs pale-yellow ( Figs. 1D, E View FIGURE 1 A – G. A – B ). Abdomen dorsally light gray with a few white spots ( Fig. 1D View FIGURE 1 A – G. A – B ), ventrally pale-yellow with one black spot on the epigastric plate and another just anterior to the spinnerets ( Fig. 1E View FIGURE 1 A – G. A – B ). Anal tubercle and posterior lateral spinnerets black, posterior median spinnerets light grey, and anterior lateral spinnerets light grey with black margin ( Fig. 1E View FIGURE 1 A – G. A – B ). Embolus filiform, in clockwise direction in left palp ( Fig. 4B View FIGURE 4 A – G ). Median apophysis bulb tumescent, covering the embolus ( Figs. 4 View FIGURE 4 A – G AB, 6C). Conductor basal lobe almost as long as wide, bean-shaped in retrolateral view ( Figs. 4A View FIGURE 4 A – G , 6C View FIGURE 6 A – F ). Median hematodocha process with a narrow base and a dorsal rounded and a pointed ventral projections ( Fig. 4A View FIGURE 4 A – G , 6C View FIGURE 6 A – F ). Prolateral tubercle of the palpal femur absent, retrolateral small and rounded ( Fig. 1 View FIGURE 1 A – G. A – B FG).

Female (paratype). Total length 2.36, carapace length 0.76, sternum length 0.43, abdomen length 1.60, leg I, length of articles: femur 1.14, patella 0.25, tibia 1.02, metatarsus 0.97, tarsus 0.61. Length of tibia II 0.48, III 0.28, IV 0.69. Colour pattern as in male, except by carapace white and legs dusky-grey ( Figs. 1F, G View FIGURE 1 A – G. A – B ). Epigynum with a deep atrium with large posterior and anterior rims ( Fig. 4C View FIGURE 4 A – G ), copulatory openings in the posterior half of atrium, posterior plate trapezoidal ( Fig. 4D View FIGURE 4 A – G ). Spermathecae ovoid with a large base and few apical pores ( Fig. 6F View FIGURE 6 A – F ), copulatory ducts short with posterior insertion in the spermathecae, hidden behind a large dorsal membrane ( Figs. 4E View FIGURE 4 A – G , 6E View FIGURE 6 A – F ), fertilization ducts inconspicuous ( Fig. 4E View FIGURE 4 A – G ).

Variation. Male (N = 6). Carapace length 0.86–0.89, sternum length 0.38–0.46, abdomen length 1.09–1.17. Female (N = 17). Carapace length 0.76–0.86, sternum length 0.43–0.51, abdomen length 1.14–1.58.
