HOLOTYPE: Female. Ecuador, Pich. Prov. , 16 km SE Sto. Domingo, Tinalandia, 680 m, 15–30­VI­1975, S. & J. Peck ( CNCI). (Specimen point mounted; sex label affixed to paper point, white, machine printed; support card, white locality label, hand printed; holotype label, red machine and hand printed.)

PARATYPES: Seven specimens, one collect­ ed from the same locality as the holotype, 15–30­V­1975 ( CMNC, 1). Ecuador: Pichincha: Tinalandia , 500 m, 16 km SE Sto. Domingo, 4–14­VI­1976, S. & J. Peck ( CNCI, 1; WOPC, 1) ; 12 km E Santa Domingo de los Colorados , 17­XI­1986, G. B. Edwards, forest, field, 670–762 m ( FSCA, 1) ; 12 km E Sto. Domingo de los Colorados , 762 m, 11–17­V­1986, J. E. Eger ( TAMU, 1) ; 17 km E Santa Domingo, 23–28­XII­1989, E. Giesbert ( FSCA, 1), ‘‘ Ecuador’ ’, 6­I­1985 ( QCAZ, 1) .

DIAGNOSIS: In specimens of this species the elytral discal setal tuft (fig. 178) is com­ prised of one patch whose setae are directed anteriorly.

DESCRIPTION: Size: Length 4.5–5.2 mm; width 2.0– 2.6 mm. Integument: Black, except legs, elytra piceous and apex of antenna testaceous. Vestiture: Head, prothorax, elytra, and protibia vested predominantly with dark setae, pterothorax, femora, and meso­metatibiae vested predominantly with pale setae; tarsi vested with dark setae, elytral middiscal setal tuft comprised of one patch whose setae are directed anteriorly. Head: Width across eyes feebly narrower than width across pronotum (32:35) finely punctate; interocular depressions and frontal umbo shallow; eyes subspherical, moderately convex; antenna as in figure 77. Thorax: Pronotum as long as wide (35:35), narrower than width of elytra across humeri (35:40), anterior transverse depression moderately indicated; elytral depth at humerus 10, greatest depth in posterior half 20, humeral umbo prominent. Abdomen: Male pygidium with posterior margin narrowed, feebly truncate, tegmen as in figure 211.

VARIATION: The available specimens did not vary appreciably.

NATURAL HISTORY: Specimens were collected during May, June, and December at 680 m; another specimen was taken (670– 762 m) in a forest field.

DISTRIBUTION (map 22): Known only from central Ecuador.

ETYMOLOGY: The trivial name anticus (in front) is a Latin adjective used here to refer to the anterior orientation of the setae of the elytral middiscal tuft.
