Philothalpus fabiolae is similar to punctate, integument without micropunctures. Philothalpus chloropennis Chatzimanolis and Pronotum : Surface smooth and glossy; longer than Ashe, 2005 because they share the following wide ( PL = 2.25, PW = 2.09), lateral margins characters: the head and pronotum are bright reddish concave; with few black microsetae along borders brown and with umbilicate punctures; the elytra are ( Fig. 2 ). Superior line of hypomeron visible in dorsal view. Disk with sparse, umbilicate punctures, punctures well-defined, distance between punctures dissimilar, from 1 to more than 3 times width of puncture, without punctures at middle. Pronotum with black microsetae on antero-lateral areas, few longer black macrosetae along borders. Scutellum: With black, glossy microsetae and sparse micropunctures. Elytra: Wider than pronotum (EL = 2.56, EW = 2.79) ( Fig. 3 ); with large punctures (about 2 punctures per 0.3 mm), punctures separated by 3–6 puncture diameters; covered with black microsetae and longer black macrosetae along borders of elytra ( Fig. 3 ). Abdomen: Terga and sterna III–VII with black setae, black macrosetae arranged in row at apical borders of all terga and sterna, posterior angles of terga and sterna II– VI with 1 longer black macroseta. Terga III– V with sub-basal carina curved and basal carina transverse; sub-basal carina fused to transverse basal carina in medial region. Distal margin of sternum VIII emarginate in males, round in females. Aedeagus: As in Figs. 4–7 . Paramere shorter and narrower than median lobe ( Figs. 4–5 ). Median lobe becoming narrow from middle to apex in lateral view ( Figs. 5, 7 ); dorsal margin straight, without convexities; apex subacute in dorsal view. Sensory spinules forming 2 longitudinal rows with 9–10 spinules each row ( Fig. 6 ) .

Etymology. The species name is in honor of Fabiola Benjumea Giraldo, mother of the first author.

Distribution. The species is known from the departments of Quind´ıo and Risaralda in the western and central Andes of Colombia between 1,231 and 1,761 m elevation ( Fig. 8 ).

Natural History. The new species is mainly associated with secondary premontane forests and Guadua forests ( Guadua angustifolia Kunth , Poaceae ) but is also found in shaded coffee plantations ( Figs. 9–10 ). There is one record from a non-shaded coffee crop area. Specimens were collected using pitfalls with decomposed squid as a bait. Specimens were collected during June–September during high and low rainy seasons.

The taxonomic key proposed by Chatzimanolis and Ashe (2005) is modified as follows to include the new species:

Couplets 1–17 without modification.

Umbilicate punctures on pronotum relatively large and numerous, average distance between punctures 0.5–1.0 times width of punctures.
