Type material. Holotype, female: Panama, Canal Zone , Albrook Forest Site , Fort Clayton , Lot no. 147, November 9/10, 1967, Hutton and Llaurado, black light trap . Allotype, male: same data as HT, except lot no. 155, Dec. 6/7, R. Hutton ; Paratype, female: lot no. 159, Dec. 21/22. HT and AT deposited in USNM , 1 PT in UTIC.

Diagnosis. Interstriae 10 sharply elevated to level of ventrite 3; protibiae without an additional mesal tooth. Female frons unique by its deep glabrous concavity appearing orange and velvet-like, and by the truncated anterior margin of the pronotum.

Description female. Length 2.1¯ 2.2 mm, 1.9¯2.0 × longer than wide; colour dark brown. Head. Eyes entire, separated above by 2.1¯2.3 × their width. Frons deeply concave from epistoma to vertex, lateral margins sharp, touching upper edge of eyes, impressed area smooth and impunctate, appearing orange and velvet-like in texture; glabrous. Antennal club setose, two sutures obscurely indicated, a faint septum present at suture 1. Funiculus 6- segmented. Pronotum weakly reticulated, subshining, shallow fine punctures separated by 2¯3 × their diameter, reaching anterior margin; anterior half with low asperities. Vestiture consisting of 6 erect setae (4–0–2). Elytra smooth and shiny, striae not impressed, punctures moderately large, shallow, in irregular rows, separated by 1¯2 × their diameter; interstriae 4¯6 × wider than striae, punctures smaller and confused, particularly so on declivity. Glabrous. Legs. Procoxae separated by 0.5¯0.6 × and mesocoxae 1.0 × the width of one procoxa. Protibiae narrow, distal teeth 1 and 2 large, of equal length, with 3¯4 additional rugae or sharp granules along towards base; protibial mucro obtuse. Meso- and metatibiae with 7 and 6 lateral, socketed teeth on distal half and third, respectively. Ventral vestiture. Setae on metasternum and metanepisternum simple.

Male. Similar to females except frons convex, weakly reticulated, with faint punctures; eyes separated above by 2.5 × their width.

Key (Wood 1982). Keys to couplet 10, with no further match.

Etymology. Composed by the Latin nominative, masculine adjective flavus, meaning yellow, and frons, meaning front of head, referring to the large yellow and velvet like concavity in the female frons.

Biology and distribution. This species is only known from the lowland type locality in Panama, attracted to black light.
