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 )

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

MALE GENITALIA ( Fig. 8 ). Abdominal segment IX annular, in lateral view, broadest laterally, posterolateral margin with some setae above preanal appendages, posterior margin slightly produced medially ( Fig. 8A ); in dorsal view, sub-rectangular with posterior margin irregular and protruded laterally; anterior margin almost straight ( Fig. 8B ). Preanal appendages digitate, longer than half the length of segment X, rounded apically with long setae ( Fig. 8A–B ). 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 ). 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 ); 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 ). Phallic apparatus with phallobase well developed and a pair of laterally directed acuminate flanges ( Fig. 8D ); phallotremal sclerite well developed, roughly Y–shaped, in ventral view ( Fig. 8D ).

Female and immature stages
