Ansa distincta Walker, 1868: 548 – 549. (syn. by STÅL 1872)

Diagnosis. Bucculae rectilinear. Outline of anterolateral margins of pronotum impunctate in dorsal view. Fovea in each basal angle of the scutellum about the same size as the diameter of a compound eye. The outer margin of each metapleural evaporatorium straight; gyrification of evaporatorium with low wrinkles. Sublateral margins of abdominal sternites not concolourous with abdominal venter (pale yellow to orange). Spiracles concolourous with abdominal venter, dark-castaneous to ferruginous. Dorsal rim of pygophore with 1 + 1 dorsal processes; extension of dorsal rim well-developed over segment X. Superior layer of ventral rim with two pairs of processes; lateral margin of each projection notched. Inferior layer of ventral rim with one median process. Segment X rec- tangular, with one tumescent process, medially. Valvulae 9 with 1 + 1 lateral sclerotized areas placed along with ring sclerite and one medially.

Colouration: General colour reddish-castaneous dorsally, with dense dark-brown to black punctures; ventral surface darkcastaneous to ferruginous with dense concolourous punc- tures. Head reddish-castaneous, punctures on basal half castaneous, those on distal half concolourous. Anten- nomeres uniformly dark-castaneous ( Fig. 9A ). Labium reddish-castaneous, apical labiomeres dark brown. Out- line of anterolateral margins of pronotum and lateral mar- gins of coria ferruginous; punctures dark-brown. Pro-, meso-, metasternum, and evaporatorium dark-castaneous to reddish-castaneous; lateral margins yellowish. Legs reddish-castaneous; femora and tibiae immaculate, yel- lowish-ferruginous. Connexivum ferruginous, lateral half yellow. Sternites dark brown to reddish-castaneous, with dark-brown punctures; sublateral band from sternite 3 to abdominal sternite 7 pale yellow to orange.

Thorax: Pronotum with anterior angles produced; anterolateral margins concave, crenulate; humeral angles slightly developed ( Figs. 8A , 9A , 21A ). Gyrification of evaporatorium with high wrinkles; outer margin of each metapleural evaporatorium straight ( Fig. 18J ). Fovea in each basal angle of the scutellum about the same size as the diameter of a compound eye ( Fig. 21C , green arrow).

Phallus ( Fig. 10 L– N): Dorsal connectives of articu- latory apparatus long. Processus capitati long, reaching phallotheca distal margin. Phallotheca piriform, shorter than width apically, with a pair of dorsal processes, wider basally than medially, and three pairsof projections: 1 + 1 in posterodorsal margin, 1 + 1 ventrobasal, and 1 + 1 in posterolateral margin, rounded. Conjunctiva with one pair of processes and two pairs of lobes: median and ven- tral lobes, membranous. Process of vesica long. Ductus seminis distalis extremely long, at least five times longer than the conjunctiva, convolute. Female terminalia ( Fig. 11 A– B): Valvifers 8 convex, at least twice as long as lat- erotergites 9, partially covering valvifers 9; mesial mar- gins juxtaposed, posterior margins sinuous; valvulae 8 not visible in ventral view. Laterotergites 8 with posterior margins obtusely projected; spiracles absent. Valvifers 9 flat, oblique, in an obtuse angle, relative to the position of segment X, with anterior margins concave and poste- rior margins straight. Laterotergites 9 triangular, obtusely projected apically, surpassing tergite 8. Female genitalia: Valvulae 9 with 1 + 1 lateral sclerotized areas placed along with ring sclerite and one medially. Ring sclerite elliptical ( Fig. 11C ). Ectodermal ductus ( Fig. 11C – D ): proximal ductus receptaculi convoluted, extremely long in relation to the length of vesicular area, at least three times longer; greater diameter. Median wall of vesicular area enlarged subproximally. Distal ductus receptaculi convoluted, extremely long, at least three times longer than vesicular area, with diameter equal to median wall of vesicular area diameter. Annular flange convergent; posterior annular flange wider than length of capsula seminalis. Pars intermedialis rectilinear. Capsula seminalis globose and smaller than pars intermedialis.

Distribution. Brazil: Amazonas and Rio de Janeiro ( Fig. 17 ).

Comments. The female specimen deposited in the ZMHB examined by FREY- DA- SILVA et al. (2002) was mistakenly conceived as a holotype. From the original description by Burmeister, it is not possible to know the number of specimens examined by the author, so this specimen must be considered a syntype. Therefore, the designation of this specimen as a lectotype is made here.

We did not examine the type material of Ansa distincta, but we accept Stål’s authority.
