Anacroneuria patioba n. sp.

( Figs. 4A–F )

Type material. Holotype, male: BR, BA: EEEWG, Riacho Patioba , S13°34'50'', W39°42'17'', 09.x.2010, light pan trap, AC et al. col. Paratypes: same data as holotype, 4 males .

Description. A small sized species. Holotype, male: forewing length, 11,5 mm. Paratypes, males (n= 4): forewing length, 11–11.5 mm (s= 0.27). General color pale yellowish. Head and pronotum yellowish; head with inconspicuous M-line, central frons area yellowish, clypeus and occiput pale yellowish ( Fig. 4A ), darker in teneral specimens ( Fig. 4B ). Antennae ochraceous, scape with dark spot laterally. Palpi pale yellowish. Pronotum with two dark strips laterally, anterior corners rounded, posterior corners rounded ( Fig. 4A ). Membrane and veins of wings conspicuous. Legs pale yellowish with dark strip in distal part of the femur. Cerci ochraceous. Sternum IX with small bristles on posterior area. Hammer simple, truncate cone ( Fig. 4C ). Penial armature ( Figs. 4D, E, F ) with pair of large distal vesicles. In lateral view, terminal tube slightly raised, distal region curved, a pair of latero-inferior lobes ( Fig. 4D ). In dorsal view, terminal tube short, with narrow base ( Fig. 4F ). Hooks regularly curved and acute apically.

Female and nymph. Unknown.

Remarks. The penial armature of A. patioba resembles that of A. cathia Froehlich, 2002 , however the new species has a shorter aedeagal apex and obliquely shaped shoulders ( Fig. 4 D-F). The aedeagus of A. cathia has the apex longer and the shoulders are not obliquely shaped. Additionally, the color patterns are different, pale yellowish in A. patioba , and light-medium brown in A. cathia ( Froehlich, 2002) . We collected a teneral specimen with remants of gills in thoracic segments, milky wings, and a dark head.

Etymology. The name Patioba refers to the stream where the specimens were collected. The name is used as a noun in apposition.
