( Figs. 11A–G View FIGURE 11 )

Material examined. BR, GO. Holotype male: Chapada dos Veadeiros, Alto Paraíso de Goiás, Ribeirão Couro, Cachoeira São Bento , 13.xii.2006 , PCB ( MZUSP). Paratypes: Chapada dos Veadeiros, Alto Paraíso de Goiás, Ribeirão Saltador , 12.xii.2006 , PCB, 7 males ( CLBA); Ribeirão Saltador , 12.xii.2006 , PCB, 8 males ( MZUSP); Loquinhas , 15.xii.2006 , PCB, 1 male ( MZUSP); Ribeirão Água Fria, 14°05'28.8"S 47°29'40.9"W, 16.xii.2006 GoogleMaps , PCB, 1 male ( MZUSP) .

Morphometric data. Holotype male, anterior wing length: 11.5 mm; paratype males (n= 17), anterior wing length: 11.5–16.0 mm.

Description. General color yellowish to ochraceous. Head and pronotum ochraceous; head with inconspicuous M-line, central frons darker, clypeus and occiput yellowish ( Fig. 11A View FIGURE 11 ). Antennae ochraceous, scape with darker spot laterally. Palpi pale yellowish. Pronotum with posterior corners rounded ( Fig. 11A View FIGURE 11 ). Wings with membranes ochraceous and conspicuous veins. Presence of 4 to 8 transverse veins between the medial and anterior cubital veins. Legs yellowish with darker stripe in distal part of the femur. Abdomen pale yellowish. Sternum IX with small bristles on posterior margin; hammer as a short truncate cone ( Fig. 11D View FIGURE 11 ). Penial armature, in dorsal view ( Fig. 11E View FIGURE 11 ), tapering gradually up to the level of distal part of the hooks where there is a rounded expansion, which subsequently narrows sharply in an elongated final process; in ventral view ( Fig. 11F View FIGURE 11 ), with pair of large distal vesicles and with hooks regularly curved with tips pointed; in the lateral view ( Fig. 11G View FIGURE 11 ), with the apex slightly inclined ventrally. Cerci ochraceous.

Remarks. Anacroneuria froehlichi was collected in the streams of Chapada dos Veadeiros, northern Goiás state. This species has a color pattern common to several species of the genus. A. froehlichi has penial armature (in dorsal view) with an abruptly narrowed apex, forming a slender process. This penial armature shape of A. froehlichi is unique, easily distinguishing it from other species of the genus.

Etymology. The name honors Claudio Gilberto Froehlich, a pioneer in Plecoptera research in South America.
