CHELIFEROUS GROUP Aphelocerus akis , new species Figures 200, 201 View Figs , 226; map 25

HOLOTYPE: Male : Mexico, Veracruz, E slope Vol. San Martin Tuxla, 22009, July 5, 1994, E. Giesbert ( FSCA). (Specimen point mounted, sex label affixed to paper point, white, machine printed; support card, white; locality label, white, machine printed; FSCA repository label, white, machine printed; holotype label, red, machine printed; plastic vial with aedeagus and abdomen).

PARATYPES: Three specimens. Mexico. Veracruz, 914 m, N slope Volcan San Martin, IV6 (year unknown) E. Giesbert ( WOPC, 2) ; Est. Biol. De Los Tuxtlas , 188359, 958059, 28 IV1991 ( WFBC, 1) .

DIAGNOSIS: Distinguishable from very similar specimens of A. apiculus , n.sp., by the trigonal shape of the last antennomere and by the more gradual slope of the elytra.

DESCRIPTION: Size: 6.0– 6.5 mm; width 2.1 mm. Integument: Black. Vestiture: Integument densely vested with prominent light and dark setae, light setae particularly prominent along lower edge of pronotum and along epipleuron. Head: Genae and epicranium expanded; interocular depressions and frontal umbo prominent; frons, epicranium, and gena very finely punctate; eyes spherical, moderately convex; width across eyes subequal to width across pronotum (45:50); antenna (fig. 226) elongate, longer than length of pronotum (65:55). Thorax: Pronotum longer than wide (55:50), very finely punctated, anterior transverse depression poorly defined, lateral margins feebly arcuate, considerably narrower than wide across humeri (49:60); elytra boldly convex, shallow longitudinal carina only faintly visible throughout elytral disc, apical slope acute, depth at humerus 25, greatest depth in posterior half 38; metafemora not extended beyond elytral apex. Abdomen: Posterior margin of male pygidium truncate, of female evenly arcuate. Male genitalia: As in figure 201; phallic plate with denticular margin (fig. 200).

VARIATION: The four specimens examined did not vary appreciably.

NATURAL HISTORY: The holotype specimen was collected during early July, whereas two paratype specimens were captured during early May, at 670 m and 945 m. One additional paratype was captured during April at the Biological Station of Los Tuxtlas.

DISTRIBUTION (map 25): Known from the northern and eastern slopes of Volcan San Martin and from the Los Tuxtlas Biological Station in southeastern Mexico.

ETYMOLOGY: The specific epithet akis (point) is a Greek noun. I wish to accentuate the testaceous coloration of the antennal apex.
