Remarks on type material. González-Sponga (2000) indicated three type specimens of N. guaiquinimensis, but only one specimen was found in the collection.

Diagnosis. Legs 1–20 with lateral tibial spurs, and 21 and 22 without tibial spurs. Femur of ultimate legs with one large spinous process; ultimate tarsus 1 equals tibia, longer than tarsus 2; basal part of tarsus 1 not divided into articles, but the distal part, not divided, with some shallow mosaic sutures; tarsus 2 without division.

Redescription of syntype. Length: 25.7 mm; ultimate legs 11.10 mm. Antennae reaching to posterior margin of tergite 3; antennae with 17 articles; two basal articles and ventral half of third article glabrous, but with some long scattered setae (1 to 6). Cephalic plate smooth, somewhat longer than wide (1.7 mm / 1.6 mm) (Fig. 30); with a short anterior sulcus and incomplete paramedian sutures reaching to half (Fig. 31).

Anterior margin of forcipular coxosternite slightly convex in the middle; coxosternal tooth-plates wide, elongate, and chitinised (Fig. 32). Coxosternite with a short median suture (Fig. 33). Distal denticle of forcipular trochanteroprefemur very short.

Tergites smooth; tergite 1 with an anterior transverse suture and complete paramedian sutures (Fig. 34), that cross the anterior transverse suture (not crosses); tergite 2 with incomplete paramedian sutures and 2 incomplete lateral sutures (two short sulci on posterior border)(Fig. 34); tergites 3–4 with oblique sutures (Fig. 36) tergites 3– 22 with complete paramedian sutures (Figs, 35, 36, 37); tergites 3–19 (3–20) with lateral longitudinal sutures (Fig. 37); tergites 5–19 (4–11) with a low median longitudinal keel; only tergite 23 (22–23) marginated, with posterior margin medially convex (Fig. 38). Sternites smooth; sternites 2–21 with an incomplete median longitudinal sulcus (Fig. 40); sternites 2–20 with short incomplete lateral sutures on the anterior margin (not described) (Figs 41, 42).

Sternite 23 shorter than sternite 22, trapeziform, with posterior margin straight (Fig. 43). Coxopleuron almost entirely covered by pore-field, only coxopleural process and a narrow area bordering posterior margin of coxopleuron remaining poreless; coxopleural processes long (3/4 sternite 23).

Legs 1–20 with small setae; legs 21–22 and prefemora of ultimate legs glabrous; legs 1–20 (4–20) with lateral tibial spurs (Fig. 39). Legs 1–22 without tarsal spurs. Prefemur of right ultimate leg with 3 large ventral spinous processes and of left leg with 4 (Figs 44, 45); femur of ultimate legs with 1 large spinous process (Fig. 45); tibia equals tarsus 1, and longer than tarsus 2 (Fig. 44); with tarsus 1 and tarsus 2 (narrow tarsi, with three segments and a distal claw); basal part of tarsus 1 not divided into articles, but the distal part with some shallow mosaic lines, but without division (Fig. 46); tarsus 2 without division (Fig. 47); tarsus 2 with a well-developed claw-shaped pretarsus (Fig. 47).

Remarks on variation. Length: from 19.50 to 33 mm; ultimate legs 7.5 to 11.9 mm. Color: body and legs yellowish; cephalic plate and forcipular coxosternite light reddish brown. Prefemur of ultimate legs usually with 4 ventral spinous processes, but in some specimens with 3 ventral spinous processes, or 3 in the right and 4 in the left legs.

Remarks on synonymy. Newportia guaiquinimensis is here considered a junior synonym of N. pilosa because of the characters of the ultimate legs. In both species, the prefemur of ultimate legs has 3 or 4 large ventral spinous processes and the femur has one large ventral spinous process. The tarsi of N. guaiquinimensis and N. pilosa are also similar. The basal part of tarsus 1 is not divided into pseudo-articles, but the distal part presents some lines. Tarsus 2 has no divisions. Locomotory legs 1–20 of N. pilosa and N. guaiquinimensis both have lateral tibial spurs.
