Cryptops (Trigonocryptops) iporangensis n. sp.
( Figures 1–3 View FIGURE 1 View FIGURE 2. C View FIGURE 3. C )
Type material. Holotype: ISLA 2191 from Ressurgência da Areias Cave, Iporonga, São Paulo, Brazil, 06/IV/2012, leg. R.A. Zampaulo
Etymology. The name is given in reference to the municipality in which the cave is located. Iporanga is from Tupi origin, a Brazilian Indian language, and means "beautiful water".
Diagnosis. This species is characterized by antennal article 1 with an inverted Y-shaped ventral suture on its proximal part; distal region of first antennal article without setae; incomplete paramedian sutures on tergites; absence of trigonal sutures; legs and antenna elongated; anterior setose area on clypeus pentagonal; a pair of a large distal spinose processes on the ultimate leg tibia (2.5 times as long as processes on prefemur and femur); 10 saw teeth on ultimate leg tibia, and 5 on tarsus 1.
Description. Length (anterior margin of cephalic plate to posterior margin of ultimate tergite) 27.5 mm. Cephalic plate 1.4 mm long, antenna 10.4 mm ( Figure 1 View FIGURE 1 A).
Head, anterior trunk segments and legs light orange to yellowish; posterior tergites and legs pale yellowish to whitish.
Cephalic plate overlapping tergite 1, slightly longer than wide; posterior corners rounded, sides convex, anterior apex slightly indented; complete paramedian sutures diverging anteriorly. Head homogeneously covered with fine setae.
Antenna composed of 17 articles ( Figure 1 View FIGURE 1 A); articles 1–9 increasing in length and decreasing in width, quadrangular; article 1 with an inverted Y-shaped suture on its proximal part on ventral side ( Figure 1 View FIGURE 1 C); articles 2– 6 1.5 times as long as wide; articles 10–17 2.5 times as long as wide. Article 1 with a high density of lanceolate setae of varied length, these strong setae progressively less abundant on articles 2–4; distal region of first article without setae, like a ring; from articles 3–4, short, fine setae form a fur-like covering with long setae only encircling the proximal end of each article.
Anterior setose area on clypeus pentagonal, bearing four lanceolate setae; a row of 15 prelabal setae; scattered setae between anterior margin of clypeus and prelabal setae ( Figure 1 View FIGURE 1 D). Labrum with shallow incision against rounded sclerotised bulge ( Figure 2 View FIGURE 2. C B).
Anterior edge of forcipular coxosternite convex on each side, with a row of 7+7 marginal setae ( Figure 2 View FIGURE 2. C B). Surface of coxosternite and trochanteroprefemur with sparse scattered long or short fine setae, with the long setae concentrated on inner margin. Tarsungulum articulated with trochanteroprefemur along wide hinge.
Apical claw of second maxilla with slender hook distally, lacking a flange along its inner edge. Dorsal brush dense, running along distal fourth of article 3 ( Figure 3C View FIGURE 3. C ).
Tergite 1 with complete anterior transverse suture; incomplete paramedian sutures on tergites 2–19, occupying roughly one fifth of the length of the posterior part of the tergite; lateral crescentic sulcus on tergites 4–19. Tergite 1–4 with homogeneous short and long setae; remaining tergites with sparse, short and long setae. Tergite 21 slightly longer than wide, posterior margin with rounded apex ( Figure 2 View FIGURE 2. C E); shallow longitudinal median depression along its posterior two-thirds; pretergites 1–20 with a transverse row of fine setae.
Spiracles elongated, elliptical.
Legs long and thin, e.g., leg 10 with prefemur 0.9 mm long, femur 0.8 mm, tibia 0.9 mm, tarsus 1 0.7 mm, tarsus 2 0.4 mm compared to tergal width of 1.2 mm. All tarsi strongly bipartite. Leg 1 with strong spiniform setae combined with short, fine setae on prefemur and femur, and tibia, pretarsus and tarsus with fine spiniform setae ( Figure 2 View FIGURE 2. C A); setae on legs 2 to 20 similar but less dense. Leg 20 prefemur and femur about equally long; tarsus 2 0.5 times as long as tarsus 1 ( Figure 3 View FIGURE 3. C A). Ultimate leg: prefemur 1.9 mm long, femur 1.8 mm, tibia 1.1 mm, tarsus 1 0.7 mm, tarsus 2 1.2 mm; prefemur and femur 4.5 times as long as than their maximal width at the distal end ( Figure 3 View FIGURE 3. C B). A pair of distal spinose processes on anterior side of prefemur, femur and tibia; spinose processes of tibia 2.5 times as long as spinose processes of prefemur and femur; numerous spiniform setae on ventral side of prefemur and femur; tibia, tarsus 1 and tarsus 2 with fine setae, concentrated on dorsal region; 10 saw-teeth on tibia ( Figure 3 View FIGURE 3. C E), 5 on tarsus 1 ( Figure 3 View FIGURE 3. C D); inner margin of tarsus 2 a ridge. Pair of accessory spines of pretarsus on legs 1–20 divergent, one third the length of pretarsus ( Figure 3 View FIGURE 3. C F); accessory spines lacking on ultimate leg.
Sternites 2–19 with median longitudinal and curved transverse sulci, their intersection forming a depression, without trigonal sutures in front of the endosternites ( Figure 2C, 2 View FIGURE 2. C D); sternite of ultimate leg-bearing segment with sides gently convex and converging posteriorly ( Figure 2 View FIGURE 2. C F); posterior corners rounded. Sternites 1–18 with sparse, short and long setae varying in density on each sternite. Coxopleural pore field elliptical, with about 70 pores. Short and moderately spiniform setae in pore field, less numerous than pores; posterior margin of coxopleuron with spiniform and fine setae.
