Brescovit. Diagnosis. Notiphilides grandis differs from other species of Notiphilides by the combination of the following characteristics: body having 151̄153 leg-bearing segments in females and 137 in males; claw of the second maxillae with only one marginal filament, in the dorsal side of the structure ( Figs 5 D̄E, 14A); a sulcus present in the distal margins of the tergites, more visible in the medial region of the body ( Figs 2 D, 7D); intermediate tergite of the postpedal segment with homogenous color ( Figs 2 F, 7F, 14B); ultimate legs without tubercle in apex of the tarsal article ( Fig. 6 F). Description. Female ( IBSP 1160). Body with 151 leg-bearing segments, length 132, and maximum width 2.8. Specimen preserved in 70% alcohol presents light yellow color ( Figs 2‒6 , 14 B), color in life unknown. Cephalic plate: smooth, with small sparse setae, wider than long, 2.4 wide, 1.8 length. Basis as wide as middle, tapering towards the distal region ( Fig. 2 B). Antennae: short and stout, inserted frontally on the cephalic plate ( Figs 2 A, B), sharply curved backwards. Length 4.1, about 2.2 times the size of the cephalic plate, and maximum width (first segment) of 0.6. Last segment elongated, about 3 times the previous in length ( Fig. 3 C). Chaetotaxy : ĪIV articles with small and sparse setae, in relatively low numbers ( Fig. 3 A). V̄XIII articles with longer setae increasing in quantity approaching the distal part ( Fig. 3 B). XIV article with two types of setae: A– long and thin and B– short and thickened, and sensilla, distributed in both ventral and dorsal region ( Fig. 3 D). Clypeus: well-defined region, with 40 short and stout scattered setae, slightly concentrated in the central region ( Fig. 4 A). Rod-shaped sensilla spread sparsely throughout the area. Labrum: well developed and sclerotized, with a single piece, almost straight, serrated, composed of more than 100 small conical teeth, uniform, slightly higher in the middle region ( Fig. 4 A, B). Mandibles: manubrium straight and thin, body concave with six lamellar combs ( Fig. 4 C‒D) that gradually decrease in size towards the apex of the structure. Dorsal region of mandible less sclerotized and more flexible, distinctly transparent ( Fig. 4 D). First maxillae: two lappets present on each side. Telopodite uniarticulated with coxal projections ( Fig. 5 A‒B), both having tiny setae in apical region and sensilla in form of small rods, more numerous in ventral region. Second maxillae: coxosternite with minute and sparse setae, chaetotaxy as in Fig. 5 C. Telopodite with many setae, which gradually accumulate in the apical region of the ventral structure. Telopodite claw well developed ( Fig. 5 D‒E), spatulate, with one filament of 4 short denticles on DR. Forcipular segment: coxosternite short and wide, 2.1 wide and 0.6 in length ( Fig. 2 A). Telopodites when closed reach the distal edge of the cephalic plate ( Fig. 2 A). FIGURE 2. Notiphilides grandis (Brölemann) . Female paratype (IBSP 1160): A, anterior part of body, ventral; B, same, dorsal; C, sternite of the LXXV segment, ventral; D, tergite of the LXXV segment, dorsal; E, terminal portion of the body, ventral; F, terminal portion of body, dorsal. Scale bars: 0.3 (B), 0.4 (A), 0.5 (C, D), 1 (E, F). Walking legs: size and morphology uniform along the body, except for the first pair, slightly reduced. Leg of the LXXV segment tapering towards the posterior region, measuring 2.3 length. Pretarsus well developed, 0.23 long, tapered tarsus, tuning in distal portion, with 0.70 length. Rectangular tibia, slightly narrower in distal region, 0.6 length. Rectangular femur, 0.5 length. Prefemur trapezoidal, 0.4 of length. Trochanter uniformly rectangular, 0.2 length. Procoxae greater than metacoxa, both in the shape of a right triangle, with the field of small pores that extend from the sternum. FIGURE 3. Notiphilides grandis (Brölemann) . Female paratype (IBSP 1160): Right antenna. A, first three antennal articles, ventral; B, articles IV, V, VI, VII, ventral; C, articles XIII and XIV, ventral; D, structures found in the distal portion of the last antennal article. Abbreviations: SA, antennal setae type “A”; SB, antennal setae type “B”; Se, antennal sensille. Scale bars: 0.04 (D), 0.2 (B, C), 0.4 (A). Pleural region: anterior and posterior part of the body with one line of paratergites ( Fig. 6 A) that gradually increase to 2 lines and 3 lines ending in the middle region ( Fig. 6 B). Posterior paratergites divide into a few articles along the distal part of body. Stigmatopleurite and prescutella similar in size and separated by a conspicuous thin membrane ( Fig. 6 A). Spiracles elliptical in shape ( Fig. 6 B). Sternites: rectangular, homogeneous throughout the body except for the first and last, little reduced. Sternite of the LXXV segment ( Fig. 6 D) measuring 0.72 length and 1.68 wide. Ventral pores present in all segments, grouped in two interconnected strips extending beyond the sternum to metacoxa and procoxa. Using oblique light, it is possible to see small structures distributed throughout the surface of the sternite where the pore fields occur ( Fig. 6 D1̄D2). Small setae scattered sparsely and dense in quantity, distributed across the sternite surface ( Fig. 6 D1). Tergites (first to penultimate) : rectangular, measuring in the middle of the body (LXXV segment) 0.73 length and 2.7 wide. Sulcus less conspicuous than in N. amazonica sp. n. , divided into two units permeate the distal structure base ( Fig. 2 D), present in the middle and distal body region. Two shallow pits are present in most body segments slightly offset to the side ( Fig. 6 C). Last leg-bearing segment: sternite slightly trapezoidal, with its base tapering to the distal part of the body ( Figs 2 E, 6E), measuring 0.32 wide, 0.75 length. Tergite, with elliptical shape ( Fig. 2 F), measuring 0.9 wide, 0.52 length, pretergite not visible Ultimate legs with six articles, slightly larger than the penultimate, left legs with a length of 2.2 versus 1.8. Undeveloped coxa, missing coxal pores ( Figs 2 E, 6E). Setae rather short and in low number are distributed sparsely, especially in the last leg articles. Sub-apex tarsal with little groove ( Fig. 6 F). Postpedal segments: intermediate tergite homogeneously staining with sub straight base measuring 0.8 in maximum width, and rounded distal part with a maximum length of 0.65 ( Fig. 2 F). Intermediate sternite well developed, in elliptical shape with a maximum length of 0.42 and maximum width of 0.94 ( Fig. 6 E). Gonopod biarticulated, tapering towards the distal portion, in the shape of an isosceles rectangle triangle with the hypotenuse turned to the central portion of the segment. Small sparse setae present on all segments, both ventral and dorsal portions ( Fig. 6 E). Male. Body length 142, maximum width 2.4. Structures as in female ( Fig. 7 ), except for the number of legbearing segments, 137. Gonopod biarticulated, gradually thinner towards the distal portion, surpassing the distal margin of the anal segment ( Fig. 7 F) in shape of isosceles triangle, with the hypotenuse facing the lateral margin of the segment ( Fig. 7 E). Variation (n=6). Body length: 132̄184. Pretergite of last leg-bearing segment visible (not hidden for predecessor tergite) in female specimens (MCN 477) from Manaus, Amazonas. One female (MCN 455) with 153 pairs of legs. Distribution. Brazil : Amazonas .
