Description:

Male.

Head: Distance between oval eyes approx. 1 facet diameter ( Fig. 12 ). Eyes appear in the shape of mulberries (probably indicative of crepuscular or nocturnal activity). Scape 2× as long as wide, 1.5× as long as spherical pedicel. Flagellomeres elongate, each narrower at about midlength; relative lengths of antennomeres: 6–4–35–28–29–28–29–27–26; GLVWDO VHJPHQWV PLVVLQJ. $OO ÀDJHOORPHUHV KDYH (SUREDEO\) VLQJOH PXVKURRP‒VKDSHG ascoids on the distal swelling ( Fig. 13 ). Relative lengths of the four visible palpus segments: 18–19–18–57; [length of distal striate segment probably underestimated, because they are not positioned horizontally]. No Newstead scales apparent.

Thorax: Wing length 4.0 mm. Venation with radial fork near tip of R 1, medial fork in basal half of wing, close to 2 nd FHOO ()LJ. ƗƗ). /HJV ODFNLQJ VSHFL¿F IHDWXUHV.

Abdomen: With 8 pregenital segments and terminalia. Tergum 6 without lateral extensions, but with median cluster of small circular pores (possibly associated with glands). Terminalia inverted, segments 8 and 9 each rotated by 90°. Terminalia: tergum 9 rectangular, distally narrower and rounded. Tergum 10 conical, setose, as long as cercus. Cercus oval, ca 2× as long as wide ( Fig. 16 ). Gonocoxite 2× as long as wide, decreasing in width distally. Gonostylus about same length as gonocoxite, slightly folded at ca PLGOHQJWK; GLVWDO SDUW DSSUR[LPDWHO\ VLFNOH‒VKDSHG, ÀDWWHQHG.$HGHDJXV ZLWK D ODWHUDOO\ FRPSUHVVHG EDVDO VFOHULWH,GLVWDOO\ ZLWK D KHDYLO\ VFOHURWLVHG UHFWDQJXODU µSODWH¶ DQG VKRUW median tip.

Notes: Based on the general shape of the terminalia, N. amazonensis sp. n. is related to N. rondanica from the Brazilian State of Rondônia ( Quate & Alexander 2000). The gonostyli are similar in shape, but the presence of pores on tergum 6, together with the shape of the aedeagus, distinguish the new species from its congeners.
