Ambrozio-Assis leg.; frog-call trap ( Physalaemus cuvieri ) 1ª3; CE-MHS . Description Female adult (n = 1) HEAD. Sensilla ( Fig. 25A ): Ocular row with 1 thick offset seta at ventral portion, about 15 setae shortly extending posteriorly. Subocular row poorly defined anteriorly, with 4 slender setae on posterior portion; vertex and interocular space with a few scattered slender setae. Postgenal row with 6 slender setae ranging from mid-posterior portion to ventromedially. With 2 ventromedial thick setae. THORAX. Sensilla ( Fig. 25B ): Antepronotum with 9 slender lateral setae. Postpronotum with 1 thick dorsal and 4 slender setae more posteriorly. Scutum, prescutal area with 2 thick and 1 intermediate, vertically aligned setae near prescutal suture; 8 intermediate and 4 slender setae anteriorly, merging with anterior portion of dorsocentral row. Antealar area with 9 thick, 4 intermediate and 6 slender setae centrally located; 8 slender setae more dorsally, near dorsocentral row. Supraalar area with 1 thick and 2 intermediate setae anteroposteriorly aligned, 11 slender setae surrounding. Dorsocentral row, posterior region with 3 thick and 1 slender offset setae; about 27 thick/intermediate and 14 slender setae filling row. Scutellum with 10 thick setae. Posterior anepisternum without setae. Anepimeron with 15 slender setae. WING. R 3 /R 1 : 0.59; R 2+3 /R 2 : 0.57. LEGS. Empodium ( Fig. 25C ) short, slender, with 3 branches. Ta1/Ta2: 2.87; Ta3/Ta4: 1.10. Distribution and biology The single specimen examined was previously recorded by Ambrozio-Assis et al. (2018) . It was collected via frog-call trap playing the call of Boana bischoffi , in Santa Catarina State , in an area of Atlantic forest, at an altitude of 470 m a.s.l. This species is otherwise known only from Costa Rica , at altitudes ranging from 1800 to 1850 m a.s.l. ( Borkent 2008 ).
