( Figs. 15–16 View Figure )

Material examined. PANAMA: Bocas del Toro Province: Cuenca 93 ( Río Margarita ) afluente Quebrada Rambala , Rambala Jungle Lodge , 8.91543°N, 82.15527°W, 3.74 km SE Rambala, 28 November 2014, E.

Fortuna Cabins , 8.77806°N, 82.19359°W, 1128 m, UV light, B. and T. Armitage, 21 January 2017, 4 ♀ ( COZEM)GoogleMaps  .

Adult habitus. General color yellow patterned with dark brown. Head mostly yellow but slightly darker yellow-brown on frons anterior to ocelli; lappets brown, antennae dark brown. Pronotum pale along median line, sublateral pigment bands brown with scattered rugosities ( Fig. 15 View Figure ). Femora almost entirely yellow, but a narrow distal band dark brown. Tibiae yellow. Wing membrane pale amber brown except for paler costal band extending from wing base almost to cord, and except for a transparent circular “window” extending beyond cord and posteríor to R-vein but not reaching posteríor margin of wing.

Male. Unknown.

Female. Forewing length 14 mm. Subgenital plate 4-lobed, inner lobes slightly smaller than lateral lobes ( Fig. 16 View Figure ). Abdominal sternum 9 bears a prominent T-shaped median setal patch.

Larva. Unknown.

Diagnosis. Only two species ( A. exquisita Stark, 1998  ; A. ventana Stark, 1998  ), currently known from Mesoamerica, have a transparent “window” in the apical region of the wings, but another species known from Colombia ( A. albimacula Klapálek  ) also shares this feature. The females of Anacroneuria exquisita  and A. ventana  are unknown and males of these species have a dark ocellar marking absent from these Bocas del Toro females. Anacroneuria albimacula  also has a dark ocellar marking, slightly different subgenital plate shape, and the species is currently known from a neotype ♂ and an additional female specimen from Antioquia Province in Colombia ( Stark et al. 1999).
