Aphelocerus citimus , new species Figures 53 , 123 ; map 21

HOLOTYPE: Male. Mexico, Ver., Jalapa , Botanical Gardens, 9 June 1983, 1320 m, C. & L. O’Brien & G. B. Marshall ( LACM). (Specimen point mounted, sex label affixed to paper point, white, hand printed; support card, white, locality label, white, machine printed; LACM repository label, white, machine printed; holotype label, red, machine printed; plastic vial with abdomen and aedeagus.)

PARATYPES: None.

DIAGNOSIS: The available specimen superficially resembles the member of A. inconstans (Gorham) , but in citimus beetles the lower aspects of the pronotum lack the dense aggregate of the white setae.

DESCRIPTION: Size: Length 6.2 mm; width 2.2 mm. Integument: Cranium, pronotum, pterothorax, and abdomen cyanescent; elytra and legs black. Vestiture: Apical half of elytra densely vested with patch of variously oriented setae; legs vested with white setae. Head: Interocular depressions and frontal umbo shallow; width across eyes equal to width across pronotum (40:40); antenna as in figure 53. Thorax: Pronotum longer than wide (47:40), considerably narrower than width of elytra across humerus (40:50), anterior transverse depression well developed, side margins moderately arcuate; elytra shallow, depth at humerus 20, greatest depth in posterior half 25. Abdomen: Male pygidium with posterior margin evenly arcuate. Male genitalia: As in figure 123.

NATURAL HISTORY: The available specimen was collected in June, at 1320 m.

DISTRIBUTION (map 21): Southeastern Mexico.

ETYMOLOGY: From the Latin citimus (nearest). I refer to the superficial resemblance between specimens of A. citimus n.sp., and those of A. inconstans (Gorham) .
