Notiphilides amazonica new species

Figures 8 View FIGURE 8 ̄13, 14C–D

Types. Female holotype, IBSP 3667, and female paratype, IBSP 3668, from Centro de Investigaciónes Jenaro Herrera (04°53`44.8”S 73°38`50.1”W), Pequeño Distrito Jenaro Herrera, Loreto, Peru, 06/04/2013, C.A Rheims & R. P. Indicatti col.

Paratypes: 2 females, MZSP 911 & MZSP 912, from RESEX Mapuá, Breves, Pará, Brazil, 4-8/12/2012, C. S. Costa col.

Etymology. The name N. amazonica was chosen in reference to the wide distribution of the species in the Amazon biome.

Diagnosis. N. amazonica sp. n. differs from other species of Notiphilides by the following combination of characteristics: 155 leg bearing segments in female; claws of the second maxillae with two marginal filaments, in dorsal and ventral side of the structure ( Figs 12 View FIGURE 12 E, 14C); evident sulcus present in tergites ( Fig. 9 View FIGURE 9 B, D); intermediate tergite of the postpedal segment with distinct dark band in the distal region ( Figs 9 View FIGURE 9 F, 14D); ultimate legs with conspicuous tubercle at the apex of the tarsal article ( Figs 13 View FIGURE 13 E–F, 14D).

Description. Male unknown.

Female (IBSP 3667): Body with 155 leg-bearing segments, length 148 and maximum width 3.1. Homogeneous segmentation, anterior and posterior part of the body slightly reduced compared to the central part. The living specimen bluish black ( Fig. 8 View FIGURE 8 C̄D), when preserved in 70% alcohol turning to gray ( Fig. 9 View FIGURE 9 ).

Cephalic plate: smooth, with small sparse setae, wider than long, 2.3 wide and 1.9 length. Basis as wide as middle, tapering towards the distal region ( Fig. 9 View FIGURE 9 B).

Antennae: short and thickened, inserted frontally on cephalic plate ( Fig. 9 View FIGURE 9 A–B), separated by a small ledge, and sharply recurved. Length 4.2, about 2.2 times the cephalic plate length, and maximum width (in the first segment) 0.5. Last article elongated ( Fig. 10 View FIGURE 10 C) with length about twice the previous one. Chaetotaxy: articles ĪIV with small and sparse setae, relatively low numbers ( Fig. 10 View FIGURE 10 A); V̄XIII articles with larger setae increasing in numbers approaching the distal part of the structure ( Fig. 10 View FIGURE 10 ĀC). Article XIV with setae as in N. grandis and a set of grouped sensilla ( Fig. 10 View FIGURE 10 D), distributed in both ventral and dorsal region of the article.

Clypeus: well-defined region, less sclerotized than the cephalic plate ( Fig. 11 View FIGURE 11 A); with approximately 60 fine setae, mainly concentrated in its central region and approximately 10 sparse sensilla, concentrated in medium frontal region ( Fig. 11 View FIGURE 11 C̄E).

Labrum: a single piece, serrated, well developed and sclerotized, almost straight ( Fig. 11 View FIGURE 11 ĀB), comprises more than 100 small teeth ( Fig. 11 View FIGURE 11 B).

Mandible: straight and thin stick, body concave in ventral region, with six lamellar combs with approximately 20 teeth each, that gradually decrease in size towards the apex of the structure. Dorsal region of the mandible less sclerotized and more flexible, distinctly transparent. ( Fig. 11 View FIGURE 11 F̄H).

First maxillae: telopodite unarticulated with coxal projections very evident, two lappets present on each side ( Fig. 12 View FIGURE 12 ĀB).

Second maxillae: coxosternite with short setae arranged mainly at the apex and middle region of the structure, evident midline and foraminal process quite flat ( Fig. 12 View FIGURE 12 A, C). Telopodite robust ( Fig. 12 View FIGURE 12 A) with well-developed apical claw, partially spatulate and carrying two rows of teeth on ventral (4 denticles) and dorsal (6 denticles) surface ( Fig. 12 View FIGURE 12 D̄E). Setae well developed in articles I, II and III, mainly present in ventral region.

Forcipular segment: coxosternite short, wide, with 0.7 length, and 2.2 maximum width. Telopodites without teeth, when closed surpassing the edge of the cephalic plate ( Fig. 9 View FIGURE 9 A). Tarsungulum well developed, about 4 times the length of three other telopodite articles combined. Forcipular tergite only slightly smaller than the tergite of the first leg-bearing segment ( Fig. 9 View FIGURE 9 B).

Walking legs: size and morphology uniform along the body, except for the first pair slightly reduced. Legs of the LXXV segment tapering to the posterior region, measuring 2.9 length. Pretarsal article with 0.27 length; conic tarsal, tapering the distal portion, with 0.75 length; tibia rectangular, slightly narrower on the distal region with 0.65 length. Femur rectangular, with 0.5 length. Prefemur trapezoidal, with a maximum length of 0.45. Trochanter uniformly rectangular, with a length of 0.25. Procoxa greater than metacoxa, both in the shape of a right triangle, with a field of small pores, which extend from the sternites.

Pleural region: anterior and posterior part of the body with one line of paratergites that gradually increases to 2 lines and finally 3 lines in the middle region ( Fig. 13 View FIGURE 13 A–B), and the middle row greater than the others. Posterior body region starting with 2 paratergite rows and ending in a single one. Paratergite divides in few leg-bearing segments, along the distal part of body. Stigmatopleurite and prescutellum separated only by a thin membrane (less apparent than in N. grandis ), usually the former being wider and longer than the latter. Spiracles predominantly with elliptical shape, a few oval and rounded ( Fig. 13 View FIGURE 13 A–B).

Sternites: rectangular, homogeneous throughout the body. The sternite of the LXXV segment ( Fig. 13 View FIGURE 13 D) measures 0.75 length and 1.53 wide. Ventral pores, varying in concentration, present in all segments and grouped into two bands interrelated in the middle region that extend beyond the sternum to metacoxa and procoxa. Small setae and glandular structures ( Fig. 13 View FIGURE 13 D1̄D2) distributed as in N. grandis .

Tergites (first to penultimate): rectangular and slightly concave in both basal and distal part, with slightly convex sides, essentially homogeneous throughout the body, measuring in the LXXV segment 0.7 length and 2.25 width. In the distal portion, two shallow pits can be found ( Fig. 13 View FIGURE 13 C), each slightly offset to one side. Sulcus very evident especially in the anterior region of the body, near the basal edge of the tergite, divided or not into two units. Pretergite present as a narrow strip, more or less visible along the body. Last leg-bearing segment without paratergite ( Fig. 9 View FIGURE 9 F).

Last leg-bearing segment: sternite rectangular ( Figs 9 View FIGURE 9 E, 13E), measuring 0.8 width and 0.2 length. Tergites with sub-straight distal margin and convex proximal margin, pretergite absent ( Fig. 9 View FIGURE 9 F). Ultimate legs with six articles and a small tubercle in the distal region of tarsal article ( Fig. 13 View FIGURE 13 ĒF). Last pair of legs lower to the penultimate, measuring in left leg 2.1 length versus 2.3 length of its predecessor. Coxopleural pores absent. Setae rather short and lower numbers are distributed sparsely, especially on the last leg article.

Postpedal segments: intermediate tergite concave, with distinct dark band in distal region ( Fig. 9 View FIGURE 9 F). Intermediate sternite well developed. Gonopods of female biarticulate ( Figs 9 View FIGURE 9 E, 13E). Small sparse setae present in all segments, both ventral and dorsal.

Variation (n=4). Body length: 148̄ 164 mm. The Brazilian specimen MZSP 911 has 7 denticles in DR and 2 in VR ( Fig. 14 View FIGURE 14 C). The condition of body with 155 pairs of legs in females was constant in our specimens.

Notes. When alive, Peruvian specimens of N. amazonica sp. n. are dark blue ( Fig. 8 View FIGURE 8 C̄D), with a great ability to shrink and stretch the body. The specimens were collected in the forest ( Fig. 8 View FIGURE 8 A), under rotten logs amid litter ( Fig. 8 View FIGURE 8 B), buried about 5 cm deep. Three spherical, yellowish, homogeneously surfaced eggs were collected with the paratype IBSP 3668 ( Fig. 8 View FIGURE 8 D̄E).

Distribution. Peru: Loreto and Brazil: Pará.
