Notalina froehlichi, Calor & Holzenthal , new species

Fig. 1

As in other members of brasiliana species­group, this species possesses lateral, acuminate flanges on the male phallobase and well­developed phallotremal sclerites. It has two pairs of processes on abdominal segment X and the median region of this segment is thick. In addition, the mesodorsal process of the inferior appendage has its apex dorsally curved in lateral view.

Adult: Color brown, with small, white, wing spots. Forewing length 10 mm.

Male: Genitalia as in Fig. 1 . Abdominal segment IX broadest ventrolaterally, with pair of small, dorsal protuberances. Segment X elevated mesally in lateral view, bearing pair of subequal dorsomesal and ventrolateral processes apically, dorsomesal process claviform, rounded apically; ventrolateral process broadly digitate, rounded apically. Preanal appendage long, about half­length of segment X, digitate, setose. Inferior appendage with apical portion elongate, digitate, setose; basal portion bearing various processes: short, flat, apically rounded basodorsal process; long, slender mesodorsal process, its apex narrowed, dorsally directed in lateral view; very short, rounded, setose, basal protuberance; and long, digitate, apically pointed mesoventral process. Phallic apparatus with phallic apodeme and phallobase well developed; phallobase with pair of dorsolaterally directed, acuminate flanges; phallotremal sclerite well developed, roughly U­shaped in dorsal view.

Holotype male: BRAZIL: Minas Gerais: Rio Caraça, near Santa Barbara, 20°01'22"S, 043°28'45"W, 728 m, 9.xi.2001 (Holzenthal, Amarante, Blahnik, & Paprocki) ( UMSP 000081361) ( MZUSP).

Paratype: BRAZIL: Minas Gerais: Rio Caraça, near Santa Barbara, 20°01'22"S, 043°28'45"W, 728 m, 9.xi.2001 (Holzenthal, Amarante, Blahnik, & Paprocki) 1 male ( UMSP).

Etymology: This species name is dedicated to Dr. Claudio G. Froehlich, the notable Brazilian entomologist from FFCLRP/USP, who has been instrumental in contributing to our knowledge of Brazilian aquatic insects.
