Domahovana naia sp. nov.

( Figs 9 –12, 55–75)

Type locality. Comunidade Lago Grande no Seringal do Recreio, Rio Gregório, Ipixuna, Amazonas State, Brazil.

Diagnosis. Body pale yellow; mesonotum with pair of large black maculae adjacent to posterior margin of pronotum; scutellum yellow ( Figs 9 –12). Male sternite VIII (Fig. 57) with posterior margin acutely rounded. Male pygofer (Fig. 58) with ventral margin strongly expanded ventrally. Style (Figs 60–61), in lateral view, slightly enlarged at median third of blade; apical portion elongated, sinuous, strongly narrowed and curved dorsally. Aedeagus (Figs 62–63) atrium with single ventral digitiform process (arrow in Fig. 63); shaft (Fig. 63) with a dorsal median lamella on apical third, and apex truncate, in caudal view (Fig. 62). Ovipositor (Figs 65–66) elongated, about three times pygofer length.

Total length. 7.2 mm (n= 1 male); 7.6 mm (n= 1 female).

Coloration. Pale yellow ( Figs 9 –12). Crown mostly orange with one black spot behind each ocellus. Ocelli light red. Pronotum with one black spot behind each eye, adjacent to lateral margin. Scutellum with pair of large black maculae adjacent to posterior margin of pronotum; scutellum yellow. Forewing (Figs 56, 64) light yellow or with a reddish tint on females, hyaline; with one black spot at base of clavus; narrow black stripe bordering anal margin of clavus, extending from black spot to basal angle.

Male terminalia. Sternite VIII, in ventral view (Fig. 57), approximately as wide as long; posterior margin acutely rounded. Pygofer, in lateral view (Fig. 58), approximately 1.5 times longer than high; ventral margin strongly expanded ventrally; posterior margin rounded. Valve approximately 1.5 times wider than long; posterior margin caudally projected forming a lobe. Subgenital plate (Figs 58–59), approximately 3 times longer than maximum width; apex acutely rounded. Style (Figs 60–61), in lateral view, slightly enlarged at median third of blade; ventral margin strongly excavated in basal portion; apical portion strongly slender, sinuous and curved dorsally. Aedeagus (Figs 62–63) with single ventral atrial digitiform process (arrow in Fig. 63); shaft with several teeth on lateroventral surface and fewer on dorsal surface; in lateral view (Fig. 63), shaft broadening towards apex; a dorsal median lamella on apical third; in caudal view (Fig. 62), shaft with lateral margins parallel distally and apex truncate.

Female terminalia. Sternite VII (Figs 65, 67) approximately 1.2 times longer than previous sternite, extending beyond posterior margin of tergite VIII; 1.4 times wider than long. Pygofer (Figs 65–66, 68) with few macrosetae distributed at apical half. First valvula (Figs 69–71) approximately 35 times longer than high. Second valvula (Figs 72–73) approximately 40 times longer than high. Gonoplac (Figs 74–75) approximately 12.8 times longer than high; expanded region encompassing apical half.

Other characters of the external morphology and terminalia as in generic description.

Etymology. The species name, a noun in apposition, refers to Amazonian mythology of the water lily plant Victoria amazonica (Poepp.) J. E. Sowerby. The legend tells the story of an Indigenous woman named “Naiá” who, in love with the moon (recognized by her tribe as a Goddess called “Jaci”), drowns when bending to kiss the moon’s reflection in a lake. Driven by this, Jaci transformed Naiá into the water lily plant. In addition, the name exalts the local culture of Amazonas State and relates to the species as specimens were coincidentally collected during the period of the full moon.

Material examined. Holotype: 1 ♂, “ BRASIL, AM, Ipixuna , Rio \ Gregório, Com. Lago Grande\ no Seringal do Recreio \ 7º10’06”S – 070º49’06”W 145m \ 17-23.v.2011 light trap \ Cavichioli, Gonçalves & Takiya” ( INPA).

Paratypes: 1 ♀, same data as holotype, except “ 18-23.v.2011 YPT Cavichioli\ Gonçalves, Rafael, Takiya et al.” ( INPA) .

Notes. Domahovana naia sp. nov. closely resembles Domahovana yamurikuma sp. nov. in having the scutellum with a pair of large black maculae adjacent to the posterior margin of the pronotum, the male pygofer with ventral margin strongly expanded ventrally, and the aedeagus atrium with a single ventral process and shaft with several small lateroventral teeth. However, Domahovana naia sp. nov. can be distinguished from the latter by apically acute male sternite VII; style with apical third longer, strongly narrowed and sinuous; and aedeagus with a median dorsal lamella on the apical third of the shaft, and apex truncate in caudal view.
