( Figs. 3 A-G) Type data: Holotype ♂ . COLOMBIA , Santander . Provincia De Vélez. Chipatá. 30.VIII.2006 , J. Chacon ( MEN-UT ) . Paratype 1 ♂ , same data, ( MEN-UT ) . Etymology: The name is a substantive that means amphora (from Latin amphora) in reference to the shape of the filament of the aedeagus. Diagnosis: The scutellum of the N. amphora has two anterior setulae to basal bristle, spherical-shaped male terminalia, aedeagus with the filament bottlelike shaped ( Fig. 3A ), distally spiculated and with spine-like apical process in ventral view ( Fig. 3D ), paramere rectangular-shaped ( Figs. 3D ), surstylus with 10 prensisetae at each side. The general shape of the male terminalia (spherical, prominent cerci and short filament) of the N. amphora is similar to those of the major group and N. parva . N. amphora differs from species in the major group because the filament of the aedeagus in this group of species is approximately the same width in all its extension, and reaching beyond the base of cerci N. parva it is the most similar species to N. amphora , in fact both species belong to the parva group which could be characterized by hemispherical male terminalia with short filament of the aedeagus (not reaching the base of cerci) and with different widths in its extension. N. parva has a chalice-shaped filament ( i.e., wider at the apex that at the base) ( Figs. 3H, I ) and 5 to 6 prensisetae at each side ( Fig. 3J ). Description: Body length 5.74-6.25 mm long, 1.92 wide at pteropleura. Head: 1.85-1.96 mm wide, 1.7-1.85 mm high, 0.77-0.81 mm long; front 0.55-0.64 mm wide in the lunule, 0.45-0.46 mm wide lower ocelar triangle; lunule with 12 setulae; postpedicel 0.84-0.94 mm long, 0.19-0.20 mm wide in lateral view; arista 1.025 mm long; longest setulae of the arista 0.076 -0.089 mm long; subvibrissal area with 3 setulae. Thorax: 1.92 mm wide, 2,25-2,48 mm long at pteropleura; anepisternum with 4 anterodorsal and 6 posterior bristles; scutellum with 5 setulae between anterior and posterior lateral bristles and 2 before lateral anterior bristle; fringes of calypteres with 12 brown setae; Wing 5.33-5.40 mm long, 1.92-2.37 mm wide, hyaline. Abdomen: 2.70-2.96 mm long. Male terminalia: 0.75-0.89 mm long, 0.82-0.88 mm wide; epandrium 0.32-0.38 mm long, 0.38-0.46 mm wide (0.83 times as wide as long) in lateral view and distally slightly concave; transversal long and thin gonopodite; paramere rectangularshape, acute at the internal corner and rounded at the external; surstylus with 10 prensisetae at each side, arranged in a sinuous line; filament of the aedeagus 0.30-0.35 mm long, 0.15 mm wide, does not reach the base of the cerci, width of section C like the base of the filament; the filament bottle-shape in ventral view, spiculated 1/3 distal in ventral view around the opening and two apical spine-like projections; cerci 0.17-0.21 mm long, 0.16-0.17 mm wide in ventral view. Host: N. amphora was collected from fruits of chili pepper ( Capsicum annuum L. var. frutescens – Solanaceae ) and guava ( Psidium guajaba L. – Myrtaceae ).
