urn:lsid:zoobank.org:act:FE0218EC-ED2F-422D-A686-E8CEF21B87B0 ( Figs. 11A–E , 12A–F )

Diagnosis. This new species can be easily recognized by the tergum X with medium-sized spine-like setae covering 1/3 apical; basodorsal lobe strongly sclerotized and produced in dorsal view; dorsomesal process absent; apicolateral process strongly sclerotized with the rounded apex in lateral view; and basal portion of inferior appendages very broad, subtriangular in lateral view.

Description. Adult male (n=1). Head brown; maxillary and labial palps brown; antennae pale brown ( Figs. 11A, B ). Thorax brown; pleuron pale brown ( Fig. 11C ). Forewing brown, with small hyaline spot at thyridial cell; forewing length 7.55 mm; forks I and V present ( Fig. 11D ); hind wing length 6.28 mm; forks I, III and V present; fork I very narrow, fork III with petiole ca. 1/3 its length ( Fig. 11E ). Legs pale brown ( Fig. 11A ); tibial spur formula 2,2,4. Male genitalia. Segment IX, in lateral view, dorsolaterally as long as ventrolaterally; anterior margin slightly concave; apicodorsal area with paired, poorly developed, closely situated protuberance; posterolateral margin strongly produced medially, bearing setae ( Fig. 12A ). Preanal appendages setose, long, slender, ca. 2/3 length of segment X; in dorsal view, apex rounded, bearing long setae ( Figs. 12A, B ). Segment X, in lateral view, saddle-shaped; anterodorsal area slightly convex; mid-dorsal area without lateral protuberance; distal area without dorsomesal and dorsolateral processes; apicolateral process strongly sclerotized, brownwish, rounded, bearing medium-sized spine-like setae ( Fig. 12A ); in dorsal view, with strongly sclerotized and produced basolateral lobe; U-shaped apicomesal incision extending anteriorly ca.1/2 length of segment X; with numerous medium-sized spine-like setae covering 1/3 apical its length ( Fig.12B ). Inferior appendage, in lateral view, with very broad basal portion, subtriangular, apical portion elongate, digitate, setose; basodorsal process rounded, smaller than basoventral process; mesodorsal process long and broad, apex acute, directed apicodorsad ( Fig. 12A ); in ventral view, basoventral process well developed, symmetrical, obliquely rounded, apex directed mesad ( Fig. 12C ); mesoventral process, in lateral view, indistinct ( Fig. 12A ); in ventral view, distinctly pointed with subtruncated apex ( Fig. 12C ). Phallic apparatus with a pair of strongly sclerotized, acuminate phallobase flanges ( Figs. 12 D-F), apex directed posteroventrad ( Fig. 12D ); phallotremal sclerite well developed, claw-shaped in lateral view ( Fig.12D ); Y-shaped, apical portion mesally directed in ventral view ( Figs. 12E, F ).

Remarks. Notalina (Neonotalina) is currently divided into two species groups ( brasiliana and roraima), which are defined based mainly on characters of the male genitalia ( Holzenthal, 1986; Calor et al., 2006). Notalina (Neonotalina) claudiofroehlichi sp. nov. is herein assigned to the brasiliana group due having a complex phallic apparatus with acuminate lateral flanges at the apex and a well-developed phallotremal sclerite. It is most similar to N. (Neonotalina) ralphi Silva-Pereira, Oliveira, Desidério, Calor & Hamada, 2022 mainly by the tergum X with slightly convex anterodorsal area, absence of processes on the median portion and the inferior appendage with indistinct ventromesal process in lateral view. However, N. (Neonotalina) claudiofroehlichi sp. nov. has the preanal appendages with rounded apex, which are acuminate in N. (Neonotalina) ralphi . In the new species the incision apicomesal of segment X has U-shaped, extending anteriorly ca.1/2 of its length, whereas inN. (Neonotalina) ralphi this incision has V-shaped, extending anteriorly ca.1/3 length of segment. Additionally, the phallotremal sclerite of the phallic apparatus in N. (Neonotalina) claudiofroehlichi sp. nov. is claw-shaped in lateral view, while in N. (Neonotalina) ralphi this sclerite is Y-shaped.

Although N. (Neonotalina) claudiofroehlichi sp. nov. is a member of the brasiliana group, the morphology of tergum X resembles that of N. (Neonotalina) matthiasi Holzenthal, 1986 from Colombia, a member of the roraima group.Both species share the presence of spine-like setae on the tergum X, but in N. (Neonotalina) claudiofroehlichi sp. nov. these setae are medium-sized, distributed on the dorsal and lateral regions of 1/3 apical, whereas in N. (Neonotalina) matthiasi they are short, distributed along the lateroventral margin of the tergite and another alone seta on the apex of each apicolateral process.

Etymology. The new species is named in honor of Prof.Dr.Claudio Gilberto Froehlich (Universidade de São Paulo, Brazil) in recognition of his efforts to the advancement of the knowledge on Neotropical aquatic insects and his contributions in supervising new entomologists.
