Description.

Female ( Figs 7-9 ). Length, 7.0 mm. Antenna black with antennomeres 1 and 2 and basal 2/3 of 3rd yellow. Head yellow with area just in front of anterior ocellus to posterior margin of head and hind orbits above eyes black; apex of mandible reddish. Thorax yellow with triangular black spot on mesoprescutum. Abdomen yellow with apical segments and sheath black. Legs yellow, apex of foretarsus and apex of midtarsus infuscated; apical 2/3 of hind tibia, apical 2/3 of hind basitarsomere, and apical 4 hind tarsomeres black. Wings fasciated, area apical to apex of stigma and area basal to intercostal veins darkly infuscated, center yellow; extreme base of costa yellow; stigma yellow; veins in yellow area, yellow; veins in infuscated area, black.

Antenna 2.0 × head width, apical 4 segments longer than broad and shorter than segments 4 and 5 combined. Lower interocular distance 0.8 × eye length; distances between eye and hind ocellus, between hind ocelli, and between hind ocellus and posterior margin of head as 1.0:1.0:1.0. Malar space absent. Hind basitarsomere longer than following tarsomeres combined. Sheath rounded at apex in lateral view. Lancet ( Fig. 14 ) with serrulae flat, each with 7-9 fine subbasal teeth; annular hairs dense, short.

Male. Length, 7.0 mm. Similar in color to female. Male genitalia in Figs 10 , 11 ; harpe tapering to rounded apex; parapenis rounded on inner margin, almost straight on outer margin; valviceps of penis valve with long, rounded dorsal lobe.

Other specimen.

Costa Rica, Area de Conservación Guanacaste, lat11.01926 long -85.40997,14 Oct 2005, 05-SRNP-33935 (1 ♀, USNM) (http://Janzen.sas.upenn.edu).

Etymology.

This species in named in honor of Luciano Capelli of San Jose, Costa Rica, for his intense and generous efforts to publicize ACG conservation with outstanding video and photographs for the Costa Rican and international public.

Food plant and biology.

One specimen, 05-SRNP-33935), was reared from Davilla nitida (Vahl) Kubitzki ( Dilleniaceae ). The larva ( Figs 21 , 22 ) is very similar to that of Waldheimia interstitialis , illustrated by Smith and Janzen (2003b: fig.3).

Remarks.

The specimen reared from Costa Rica is not complete and is not included in the type series. However, enough is present, including the lancet, to show it is the same as the specimens from Panama. It DNA barcodes as far from the other 4 species of Waldheimia that were DNA barcoded, as they do from each other.

This species is similar to Waldheimia duckei Konow of South America, but Waldheimia lucianocapellii is separated by the mostly black mesoprescutum, white base of the hind tibia and base of the hind basitarsomere, yellow antennomeres 1 and 2 and base of 3rd, head pale from above antennae to clypeus, and low flat serrulae of the lancet ( Fig. 14 ). The only other species with which it might be confused in Costa Rica is Waldheimia fascipennis , which also has the wings broadly black at the base and apex and yellow at the center; however, Waldheimia fascipennis has an entirely orange head, entirely white hind basitarsomere, and deeper serrulae on the lancet ( Fig. 15 ).
