Philoponella fluviidulcifis View in CoL new species

( Figs. 1C View FIGURE 1 A – G. A – B , 3A–D View FIGURE 3 A – D , 6 View FIGURE 6 A – F AB, 7A)

Type. Male holotype ( UFMG 11538) from Brazil, Minas Gerais: Marliéria (Parque Estadual do Rio Doce, 19º42’S 42º44’W, 597 m), 1–10 September 2003, T. Rodrigues et al. leg.

Etymology. The specific name is a noun in apposition composed by the fusion of two Latin words, fluvii (river) and dulcifis (sweet). This name alludes to the type locality of the species, Rio Doce (“Sweet River”) State Park.

Diagnosis. Males of Philoponella fluviidulcifis resemble those of the Philoponella semiplumosa species group (see Opell 1979: 532) in having the retrolateral tubercle of the palpal femur longer than the prolateral one ( Fig. 3D View FIGURE 3 A – D ), and the conductor spike longer than the apical projection of the median apophysis spur, but can be distinguished from other members of the group and all other tropical American Philoponella species by the median apophysis spur with a large base and the apical projection forming a 180° hook ( Figs. 3A, B View FIGURE 3 A – D ; 6A).

Description. Male (holotype). Total length 3.72, carapace length 1.40, sternum length 0.56, abdomen length 2.19, leg I, length of articles: femur 2.08, patella 0.28, tibia 1.86, metatarsus 1.83, tarsus 0.79. Length of tibiae II 0.69, III 0.51, IV 1.02. Carapace pale-yellow with two paramedian longitudinal dark bands ( Fig. 1C View FIGURE 1 A – G. A – B ). Chelicerae pale-yellow. Endites, labium and sternum light grey. Legs pale-yellow ( Fig. 1C View FIGURE 1 A – G. A – B ). Abdomen dorsally pale-yellow with white spots and posterior region dark ( Fig. 1C View FIGURE 1 A – G. A – B ), ventrally light brown. Anal tubercle and spinnerets light brown. Embolus filiform, in clockwise direction in left palp ( Figs. 3A, B View FIGURE 3 A – D ). Median apophysis bulb not tumescent and not covering the embolus ( Figs. 6A, B View FIGURE 6 A – F ). Conductor basal lobe longer than wide, canoe-shaped in retrolateral view ( Fig. 3A View FIGURE 3 A – D ). Conductor spike rounded in retrolateral view ( Fig. 3A View FIGURE 3 A – D ), acute and curved in apical view ( Fig. 3B View FIGURE 3 A – D ) and longer than the apical projection of median apophysis spur ( Figs. 3A, B View FIGURE 3 A – D ).

Female. Unknown.

Variation. Male (N = 4). Carapace length 1.19–1.40, sternum length 0.66–0.71, abdomen length 1.91–2.67.
