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 View Figs ). 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 View Figs ); 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 View Figs ). 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 View Figs . Paramere shorter and narrower than median lobe ( Figs. 4–5 View Figs ). Median lobe becoming narrow from middle to apex in lateral view ( Figs. 5, 7 View Figs ); dorsal margin straight, without convexities; apex subacute in dorsal view. Sensory spinules forming 2 longitudinal rows with 9–10 spinules each row ( Fig. 6 View Figs ) GoogleMaps .

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 View Figs ).

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 View Figs ). 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.

18(12). Surface of pronotum near apico-lateral angles with rugose microsculpture. Umbilicate punctures on pronotum relatively large and numerous, average distance between punctures 0.5–1.0 times width of punctures. Width of impunctate line at midline of pronotum equal to about width of 2 punctures on anterior half and 1 puncture on posterior half. Impunctate area at middle of epicranium
