Apex of phallic guide short, with apex thin and downward directed (Fig. 96). Ejaculatory apodeme fan-shaped, with one lateral margin rounded (Fig. 97). Phallus bifid, with ejaculatory ducts long and thin, apparently covered by a membrane with spines on apex and apical hook (Fig. 96). Female. Unknown. Geographical distribution. Colombia (Bolívar) (Fig. 131). Etymology. From the Latin spina = spine. Refers to the spines in the membrane that attach the ejaculatory ducts. Habitat. The specimens were collected with Malaise traps at ground level. The vegetation of collection site corresponds to areas of tropical dry forest in the Caribbean region. Taxonomic notes. Based on male specimen N. spinifera sp. nov. is similar in appearance to N. miriamae Rafael, 1992 [see figures 42.9, 42.22, 42.57, 42.58, presented by Rafael (1992) and figures 1.H, 2.K, 3.K, presented by Souza & Ale-Rocha (2009)], N. semispiralis Rafael & Rosa, 1991 [see figures 7–11 presented by Rafael & Rosa (1991) and figures 1.N, 3.Q, presented by Souza & Ale-Rocha (2009)], and N. sumapazensis sp. nov. (Figs 114–125). It differs from N. miriamae by having the scutellum whitish yellow, light brown pruinose (Figs 86, 88) (versus scutellum dark brown to black, gray pruinose in N. miriamae); vein r-m located before the basal third of the upper section of the cell dm (Fig. 89) [versus vein r-m located after the basal third of the upper section of the cell dm, figure 42.22, presented by Rafael (1992)]; section between cell dm and vein M 2 greater than vein dm-m (Fig. 89) [versus section between cell dm and vein M 2 equal than vein dm-m, figure 42.22, presented by Rafael (1992)]; fore and hind coxae whitish yellow, mid coxa brown (versus all coxae black); both surstyli with tips outward directed (Fig. 93) [versus both surstyli with tips inward directed, figure 42.57, presented by Rafael (1992)]; right surstylus slightly shorter and thin (Fig. 93) [versus right surstylus slightly longer and thickened, figure 42.57, presented by Rafael (1992)]; both surstyli with one small lobe ventrally in the proximal third when seen in lateral view (Figs 94–95) [versus left surstylus with subapical sinus ventrally in the proximal third when seen in lateral view, figure 42.58, presented by Rafael (1992)]. It differs mainly from N. semispiralis in having the mid coxae brown (versus mid coxa black in N. semispiralis); mid trochanter brown (versus mid trochanter black); scutellum light brown pruinose (Figs 86, 88) (versus scutellum gray pruinose); both surstyli with one small lobe ventrally in the proximal third, when seen in lateral view (Figs 94–95) [versus both surstyli with two ventral lobes, when seen in lateral view, figures 9–10, presented by Rafael & Rosa (1991)]. It differs mainly from N. sumapazensis sp. nov. by having the postpronotal lobe whitish yellow (Figs 85, 88) [versus postpronotal lobe light brown in N. sumapazensis sp. nov. (Figs 114, 116)]; scutellum whitish yellow (Figs 86, 88) [versus scutellum dark yellow (Figs 115–116)]; section between cell dm and vein M 2 greater than vein dm-m (Fig. 89) [versus section between cell dm and vein M 2 smaller than vein dm-m (Fig. 117)]; both surstyli with tips outward directed (Fig. 93) [versus both surstyli with tips downward directed (Fig. 121)]; both surstyli with one small lobe ventrally in the proximal third when seen in lateral view (Figs 94–95) [versus both surstyli with one small lobe ventrally in the middle third when seen in lateral view (Figs 122–123)]; ejaculatory apodeme fan-shaped, with one lateral margin rounded and other margin acute (Fig. 97) [versus ejaculatory apodeme fan-shaped, with two lateral margins acute (Fig. 125)].
