Gonzalez-Rodriguez, Liza M., García-Hernández, Andrea L. & Clarkson, Bruno, 2017, First records of water scavenger beetle species (Coleoptera, Hydrophilidae) from Quindío Department, Colombia, Check List 13 (5), pp. 605-620 : 616

Phaenonotum sp. 1 ( Figs 21, 45)

Diagnosis. Body 1.60–2.40 mm long. Body oval in shape. Dorsal coloration entirely black. Dorsal punctation on head and pronotum fine and dense, on elytra sparser. Meso-metaventral process slender and acuminate on anterior margin, widened posteriorly. Parameres as long as median lobe, apex slightly acuminate, convex on outer margin, wide medially; median lobe wider than parameres, slightly acuminate at apex; phallobase shorter than parameres.

Geographic distribution. First record from Quindío Department and from Colombia.

Material examined. Colombia, Quindío Department, La Tebaida Municipality, Pizamal neighborhood, 04°24ʹ 50.2ʺ N, 075°51ʹ06.3ʺ W, 1012 m a.m.s.l., 2015-I-30, L.M. González coll., CIUQ 10678–10682 (11 males, 19 females).

Remarks. Specimens were found in marshes on muddy substrates and on submerged vegetation. Phaenonotum sp. 1 was very difficult to identify given that in many cases the genitalia have slight differences. The external morphology of this species needs to be carefully studied.
