description: Neoscutops ranyzeae sp. nov.
(Figs. 46–50, 60, 73)
Diagnosis. Head triangular in frontal view; frons shiny brown; face shiny yellow; scape and pedicel dark yellow, first flagellomere yellow; palpus dark brown; scutum brown with anterior margin and postpronotal lobe pale brown; legs brown except apical 1/3 of tibiae and tarsi whitish-yellow; fore femur with series of long strong setae on posteroventral surface; surstylus contiguous with epandrium; female hypoproct wide and short, anterior margin with a small median cleft.
Description. Holotype male. Body: 1.85 mm. Wing: 1.8. Thorax: 0.75. Head (Fig. 73). Frons shiny, brown. Face shiny, yellow, with scattered, thin, elongate yellow setae. Parafacial yellow. Gena yellow, with scattered, short brown setae and one long robust seta below. Antenna: scape and pedicel dark yellow, first flagellomere yellow; pedicel with 2 preapical short black setae besides the thin marginal ones; first flagellomere short, oval; arista subbasal dorsal pale brown to yellow with 8 dorsal and 3 ventral rays. Mouthparts: proboscis pale brown; palpus short, clavate, black with thin brown setae; clypeus yellow, U-shaped. Postcranium brown with scattered brown microtomentum and band of dense yellow microtomentum on lateral margin of eye, with short brown setae. Eyes with interfacetal setae sparse. Setae: 1 lateral vertical and 1 medial vertical pairs long, the lateral pair almost long as medial pair; 1 orbital pair inserted below the half of frons, as long as lateral vertical setae; 1 postocellar pair robust, divergent, shorter than ocellar; 1 long proclinated ocellar pair inserted laterally on the ocellar triangle; all setae pale brown.
Thorax brown, yellow on postpronotal lobe; pleurae and scutellum clothed in scattered brown microtomentum; scutum with short brown setulae. Setae: 1 postpronotal short and weak; 2 short and dark notopleural; 1 postsutural supra-alar long; 1 postalar short; 1 long prescutellar dorsocentral; 1 scutellar pair very long (approximately 2x the length of the prescutellar dc), convergent; 1 katepisternal short and weak, all setae brown.
Legs brown except apical 1/3 of tibiae and tarsi whitish-yellow. Fore femur with posteroventral series of long and strong dark brown setae; mid tarsus without ventral black spines. Apicoventral spine of mid tibia also short, not reaching middle of first tarsomere.
Wing pale brown, progressively paler toward apex, apex hyaline; the longitudinal fold crosses the vein dm-cu above middle.
Abdomen brown, shiny, with dense brown microtomentum; coating setae short and weak, brown, almost inconspicuous dorsally, longer on lateral surface of tergites. Tergite 1+2 divided longitudinally by median unsclerotized line from base to half; sternite 6 concave anteriorly (Fig. 48); tergite 6 and syntergosternite 7+8 fused laterally (Fig. 49). Terminalia: phallus short, slender (Fig. 47); cercus large, membranous, closely approximated (Fig. 46); postgonites short (Fig. 46); surstylus contiguous with epandrium, not articulated (Figs. 46, 47); ejaculatory apodeme small, elongate.
Female. As in the male except for clypeus brown on apex. Terminalia (Fig. 50): syntergosternite 7 well sclerotized; sternite 8 rather triangular, distal margin slightly concave in middle; hypoproct wide and short, anterior margin with small median cleft; cercus small.

Distribution. Brazil (Amazonas).
Etymology. The specific name is given in homage to Dr. Ranyse Querino of the Empresa Brasileira de Pesquisa Agropecuária - EMBRAPA, collector of the specimens.
Variations. In some paratypes the pedicel has a brown spot on the dorsum, mid and hind tibiae, with the anterior and posterior surfaces yellow and an incomplete dark brown preapical ring. The surstylus is also shorter than in the holotype.
Remarks. This species is very similar to Neoscutops minor sp. nov. but can be distinguished by the yellow clypeus, larger size and characters of the male and female terminalia.
