Anacroneuria yameo Stark & Sivec

Anacroneuria yameo Stark & Sivec, 1998:60 .

Holotype ♂, Río Nanay , Callicebus Research Station, Mishana, Loreto, Peru (USNM)

Material. COLOMBIA: 1♀, Amazonas , Municipio de Leticia , Quebrada La Arenosa , Km 11 road to Tarapacá, Río Amazonas middle basin, light trap, S 04 ° 07 ′ 30 ″, W 69 ° 57 ′ 25 ″, 26 May 2002, D. Emmerich ( MEUV) .

Discussion. This species was previously reported from this same locality by Zúñiga et al. (2006) but the female specimen, collected at the same time, had not previously been studied. This specimen matches the color pattern of the holotype closely and is an almost

certain match. The locality is in the lowlands of Río Amazonas central basin in the small Colombian “trapezium” between Peru and Brasil. The water of the creek is slightly colored, the water temperature at the time of collection was 24°C and natural riparian vegetation is present.

Female. Forewing length 11.5 mm. Subgenital plate 4-lobed, mesal lobes narower and slightly longer than lateral lobes and divided by a shallow, wide triangular notch ( Fig. 42 ); lateral lobes divided by narrow notches. Transverse sclerite of sternum 9 weak, obscure; mesal setal patch with conspicuous long red brown setae in lateral patches; median stalk with thin short setae.

Egg. Spindle shaped with broadly rounded apex; typical of genus ( Fig. 43 ).
