Janulus nebulosus ; Mello-Leitão, 1943: 167 (examined, misidentification non P. nebulosa ( Simon, 1895) .

Type material Holotype ♂, paratype ♀, Parque Copesul de Proteção Ambiental (currently Estação Ambiental Braskem , 29° 56′ 34″ S, 51° 43′ 4″ W), Triunfo, Rio Grande do Sul, Brazil, 08.I.1997, M. A. L.

Etymology The specific epithet is a patronym in honor of Brazilian agronomist and environmentalist José Antônio Kroeff Lutzenberger, for his extraordinary effort to make humanity care about nature and by was a great defender of the natural environment in Brazil and worldwide, being an internationally known environmental activist.

Diagnosis Janula lutzenbergeri sp. nov. is similar to J. malachina ( Simon, 1895) by the presence of a single median pointed projection in the dorsum of the abdomen, but differs by having a subtriangular of the abdomen with straight lateral angles (Fig. 27), while the abdomen in J. malachina has rounded lateral angles (Fig. 32). The male palp of Janula lutzenbergeri sp. nov. (Figs. 24, 42, 43, 44) resembles those of J. malachina in the shape of conductor, but differs by the apical process of conductor with obtuse apex, while the apical process in J. malachina is bird head shape (Fig. 31). Females of Janula lutzenbergeri sp. nov. also resemble those of J. malachina (see Levi, 1964a, figs. 32, 33), but differ by the wide spermathecae base and distally tapered (Figs. 25, 26) and by the wide copulatory ducts that surround the spermathecae (Fig. 26).

Male (holotype). Carapace (Fig. 27) pale yellow, lateral grayish brown, and darkened margin. Clypeus grayish. Chelicerae, labium, and endites pale yellow. Legs pale yellow, femora and tibiae apex and base of metatarsi III and IV grayish. Abdomen subtriangular with dorsal median pointed projection (Fig. 27), posterior region projected. Dorsum light gray with longitudinal white dots band; posterior region, from the tubercle, with gray streaks. Lateral region of the abdomen grayish. Venter light gray. AME larger than the others and separated from each other by almost their diameter. PLE smaller than the other eyes.

Measures. Total length 1.90. Carapace: length 0.75, width 0.67. Leg formula 1423. Leg length I: femora 1.62; patellae + tibiae 1.77; metatarsi 1.72; tarsi 0.65; total 5.76. Patellae + tibiae: II 0.97; III 0.70; IV 1.33.

Female (paratype MCN 28,178). Color and shape of the abdomen, carapace, and legs as in the male. AME larger than other eyes and separated by little more than half their diameter. PLE smaller than the other eyes. PME distant from each other by an eye diameter.

Measures. Total length 2.05. Carapace: length 0.85, width 0.72. Leg formula 1423. Leg length I: femora 1.62; patellae + tibiae 1.67; metatarsi 1.75; tarsi 0.65; total 5.69. Patellae + tibiae: II 0.98; III 0.68; IV 1.22.

Variation Total length in males (n = 10) 1.62–2.00; carapace 0.65–0.77; femur I 1.32–1.75. Females (n = 10) total length 1.95–2.70; carapace 0.80–0.87; femur I 1.47–1.55. In some individuals, the abdomen with reduced white pigment, in others reddish-brown abdomen.

Note. Males and females were collected together in several locations in Brazil.

Etymology The specific name is a noun in apposition, taken from the type locality.

Diagnosis Females of Janula mamiraua sp. nov. resemble those of J. bicruciata ( Simon, 1895) (see Levi, 1964a, figs. 69–71) by the presence of a depression in the epigynal plate and by the spermathecae elongated and loops of copulatory ducts encircling spermathecae (Fig. 29), but differ by the depression wider than long and situated posteriorly (Fig. 28), while the depression in J. bicruciata is median and longer than wide.

Female (holotype). Carapace oval, yellow orange, except central area light yellow, with darkened margin. Conical tubercles behind the anterior median eyes developed. Chelicerae, labium, and endites yellow. Legs yellow, I–III grayish on the sides; leg IV darkened, except metatarsi and tarsi. Abdomen (Fig. 30) trapezoidal, yellow orange anteriorly darkened, and with a median-posteriorly transversal dark brown band. Medially with two muscle impressions, orange. Venter yellow orange with two bands, one white and one dark, on each side of the spinnerets. PLE smaller than the other eyes. AME larger than other eyes and separated their diameter. PME distant from each other by an eye diameter.

Measures. Total length 1.87. Carapace: length 0.72, width 0.65. Leg formula 1423. Leg length I: femora 1.45; patellae + tibiae 1.52; metatarsi 1.42; tarsi 0.52; total 4.91. Patellae + tibiae: II 0.82; III 0.54; IV 1.25.
