Diagnosis

Notalina ( Neonotalina) daniae sp. nov. is identifiable by the distinctive structure of segment X, which features a V-shaped apicomesal incision creating two large, rounded lobes. Additionally, in dorsal view, there are two small protuberances laterally at the mid-length of segment X with two setae in each one. The mesoventral processes of the inferior appendages are sub-quadrate with a pointed projection near the apex, while the mesodorsal processes are long, thin, and flat.

Notalina ( Neonotalina) daniae sp. nov. is assigned to the N. brasiliana species group as defined by Holzenthal (1986). The new species shares with Notalina cipo , N. claudiofroehlichi , N. morsei , and N. ralphi the shape of segment X with apicomesal incision forming two large lobes and the absence of an apicomesal process. However, N. cipo and N. morsei have a wider apicomesal incision of segment X and V-shaped with long lobes and straight apices, while in the new species the apicomesal incision is shorter than ⅓ of tergum X. Notalina daniae can be confused with N. ralphi and N. claudiofroehlichi by showing a similar pattern in the apicolateral processes of segment X that forms two rounded and setose lobes, but in N. claudiofroehlichi these lobes are strongly sclerotized apically and the apicomesal incision of segment X is U-shaped, extending anteriorly ca ½ of its length, while segment X of the new species is membranous. Although Notalina ralphi possesses the V-shaped incision extending anteriorly ca ⅓ length of the segment like in N. daniae , it differs from N. daniae by the absence of lateral protuberances in segment X, and by having a row of 5–7 short, stout setae situated subapically, while N. daniae has two small protuberances at the middle-length of segment X in dorsal view. Another difference is observed in the mesoventral process of the inferior appendages in lateral view, where in the new species N. daniae the inferior appendage is subquadrate with a small projection near the apex and in N. ralphi and N. claudiofroehlichi the inferior appendage is indistinct or rounded.

Etymology

The species epithet ‘ daniae ’ is a noun in the genitive case to honor Prof. Dra Daniela ‘Dani’ Takiya, who collected the new species.

Description

Adult male ( Figs 7–8 View Fig View Fig )

COLOUR (pinned). Head and thorax brown with off-white spots. Legs, palps, and antennae golden brown ( Fig. 7A View Fig ). Tibial spur formula 2, 2, 4. Length of forewing: 7.00 mm (n = 1).

MALE GENITALIA ( Fig. 8 View Fig ). Abdominal segment IX annular, in lateral view, broadest laterally, posterolateral margin with some setae above preanal appendages, posterior margin slightly produced medially ( Fig. 8A View Fig ); in dorsal view, sub-rectangular with posterior margin irregular and protruded laterally; anterior margin almost straight ( Fig. 8B View Fig ). Preanal appendages digitate, longer than half the length of segment X, rounded apically with long setae ( Fig. 8A–B View Fig ). Segment X, in lateral view, almost straight, featuring a small protuberance medially with two setae, and having a rounded apex with sparse stout setae; in dorsal view, broad at the base with two small membranous protuberances laterally at the middle-length of segment X and a V-shaped incision at the apex, dividing it into two rounded lobes ( Fig. 8A View Fig ). Inferior appendages, in ventral view, broad at base with apical portion elongate, digitate and setose; basodorsal process rounded and well developed, basoventral protuberance robust, rounded, and very setose ( Fig. 8C View Fig ); mesoventral process with approximately half-length of apical portion, rounded, protrude with a small point near apex; in lateral view, very large, subquadrate, setose on the posterior margin, with a pointed protuberance near the apex; mesodorsal process digitate long, thin, flat, like a blade with acute apex inward directed ( Fig. 8A View Fig ). Phallic apparatus with phallobase well developed and a pair of laterally directed acuminate flanges ( Fig. 8D View Fig ); phallotremal sclerite well developed, roughly Y–shaped, in ventral view ( Fig. 8D View Fig ).
