Type Locality. Peru, Dept. Huánuco, N side Cerro Carpish , 2,500 m .

Diagnosis. This species is similar to several other species of Gelae (see Diagnosis under G. baen ). It differs from these similar species in being very large (TBL. 3.00 mm). Also, the male median lobe is extremely robust and broad in both dorsal and lateral aspects ( Figs. 15–16 ). The apex in ventral aspect is rather abruptly attenuated ( Fig. 15 ), and the apex is abruptly curved dorsad in lateral aspect ( Fig. 16 ).

Description. Body large (TBL ¼ 3.03–3.46 mm), robust (PNW/TBL ¼ 0.45–0.46), laterally broadly rounded, weakly contractile.

Head brown, clypeus yellow-brown; pronotum yellow with large, diffuse, medial brown macula; elytra brown, dark brown at base and along margins; venter and legs brown; antennae and palpi yellow, antennal club brown.

Head moderately broad (MDL/PHW ¼ 0.66–0.68), dorsally flattened; constricted immediately posterad of eye; very finely and sparsely punctate, surfaces shiny and smooth between punctures; eyes large, rounded, protruding; fronto-clypeal suture continuous, but fine, medially; clypeal margin moderately protruding, extending beyond level of anterolateral margins of frons ( Fig. 29 ); labrum broad, transversely rectangular; antennae (ratios: length I:II:III ¼ 1.3:1.0:1.3, width VII:VIII:IX ¼ 1.0:1.0:2.2). Pronotum broad (PNL/PNW ¼ 0.58–0.63), laterally not strongly produced, lateral margins nearly straight, anterolateral angle subquadrate, posterolateral corner distinctive, more angulate than anterolateral corner; punctation similar to that of head. Elytra robust (SEL/ELW ¼ 0.93–1.16); lateral margins broadly rounded; punctation fine and sparse, similar to pronotum; sutural stria prominent, extending about 1/2 length of elytron. Mesosternum strongly concave posteriorly, with prominent lobe extending ventrally between mesocoxae, anterior portion moderately narrow. Metasternum broad medially (MTL/MTW ¼ 0.36–0.40).

Male tarsi 5–5–4; pro- and mesobasotarsomeres only slightly expanded and with small ventral field of adhesive setae; metafemur slender, unmodified; metasternal fovea small, inconspicuous, located anterad of middle, with small pencil of fine, long setae. Median lobe in lateral aspect very broad, robust, straight, apical portion narrowed, apex abruptly bent dorsad and pointed ( Fig. 16 ); in ventral aspect very broad, lateral margins sub-parallel, apically abruptly narrowed, very broadly acuminate, apex narrowly rounded ( Fig. 15 ); operculum very broad, apically relatively broadly emarginate ( Fig. 15 ); lateral lobes short, broad, directed slightly dorsad, without setae ( Figs.15–16 ).

Female tarsi 5–4–4.

Etymology. This species is named donut , a whimsical arrangement of letters that is pronounced like the English word ‘‘doughnut.’’

Distribution. Gelae donut is known from highland areas in Bolivia and Peru.

Discussion. This species has been collected from cloud forest and montane rain forest. Elevation records are from 1,600 –2,300 m.
