Lycomorphon iwokrama sp. n.

Type material. Holotype: male, GUYANA, Region 8; Iwokrama Research Centre, N4°40' W58°41', ca. 60m; 17–21.vi.2014, general collecting; Michael Geiser & Roy Canty leg. Secondary label: BMNH {E} 2014-131 Biodiversity Initiative ; BMNH(E) 1499603. (BMNH)

Diagnosis. Antennomere 3 slightly longer than 4, pronotum wider than long, each elytron with 3 strong costae, costa 3 reaching apical 1/4, parameres slightly shorter than half of phallus.

Description. Body and pronotum dark brown. Elytra dark brown with almost circular yellow spot at midlength. Antennae dark brown except for the light brown terminal antennomere ( Fig. 4 ). Trochanter yellow, femur dark brown with proximal 1/10 yellow.

Interocular distance 1.2 times longer than eye diameter. Antennomere 3 1.2x longer than 4 and 2.7x longer than antennomere 2. Mandibles curved. Labial palpi short. Maxillary palpi elongate, ultimate palpomere pointed apically, palpomere 2 1.1x longer than 4 and 1.8 times longer than palpomere 3. Labrum slightly rounded distally. Pronotum trapezoidal, 1.3 times wider medially than pronotal length medially, median longitudinal carina simple in anterior half, forming longitudinal groove posteriorly. Elytra elongate, 3.6 times longer than humeral width; each elytron with 3 strong costae, costa 3 weak and absent at apical 1/4, costa 1 strong at basal half, reticulate cells regular, largely rectangular. Tibia 1.2x longer than femur and 2.8 times longer than trochanter. Abdominal sternum 8 with deep median emargination distally. Sternum 9 elongate, constricted at basal 1/3, rounded distally, and proximally rounded with pointing end. Phallus straight in lateral view, apex rounded, teary orifice in distal 2/3. Parameres slightly shorter than half of phallus length, rounded apically in lateral view ( Figs. 1–3 ). Body length: 6.4mm, humeral width: 1.5 mm.

Etymology. The name in a nom in apposition, and refers to the species occurrence site.
