Adetaptera schaffneri Santos-Silva, Nascimento and Wappes , sp. nov.

( Fig. 46–49 )

Description. Male. Integument mostly brown, interspersed with irregular dark reddish-brown areas (lighter on some areas); anteclypeus and labrum reddish-brown; palpomeres yellowish-brown; distal 2/3 of antennomere III reddish brown; basal third of antennomere IV reddish brown; remaining antennomeres brown; tibia gradually reddish brown on distal half; tarsi mostly dark reddish brown.

Head. Frons coarsely, sparsely punctate; with light yellowish-brown pubescence (lighter depending on light intensity), abundant, but not obscuring integument, slightly denser laterally and toward antennal tubercles; with a few long, erect brownish setae close to eyes. Vertex coarsely, sparsely punctate; with yellowish-brown pubescence (lighter depending on light intensity), dense laterally, sparser centrally. Area behind eyes coarsely, abundantly punctate (punctures coarser behind lower eye lobe); pubescence as on sides of vertex. Genae 1.45 times length of lower eye lobe; with a few coarse punctures toward ventral surface, smooth toward dorsal surface; pubescence as behind eyes (distinctly sparser in area close to frons). Antennal tubercles finely, sparsely punctate anteriorly, smooth in remaining surface; pubescence as on frons, slightly sparser in some areas. Median groove absent. Postclypeus finely, sparsely punctate in wide central area, smooth laterally; with sparse light yellowish-brown pubescence, with a few long, erect brownish setae interspersed. Labrum coplanar with anteclypeus at posterior 2/3, inclined at anterior third (concave at center of anterior area); with a few short yellowish-brown setae except short, dense yellow pubescence in concave area. Distance between upper eye lobes 0.94 times length of scape; in frontal view, distance between lower eye lobes 1.30 times length of scape. Antennae as long as elytra (only holotype measured), slightly surpassing middle of elytra; scape, pedicel, antennomere III, and basal 2/3 of antennomere IV with moderately sparse light yellowish-brown pubescence (lighter depending on light intensity); remaining surface of antennomere IV and antennomeres V–XI with slightly paler pubescence; antennomeres III–IV with long brownish setae ventrally, more abundant on III; remaining surface of III–IV and entire surface of V–XI with short, sparse, erect yellowish setae. Antennal formula (ratio) based on length of antennomere III: scape = 0.55; pedicel = 0.18; IV = 0.69; V = 0.34; VI = 0.24; VII = 0.22; VIII = 0.18; IX = 0.18; X = 0.18; XI = 0.20.

Thorax. Prothorax longer than wide, cylindrical, slightly widened centrally. Pronotum coarsely, sparsely punctate; with narrow, longitudinal light yellowish-brown pubescent band centrally (lighter depending on light intensity), from base to apex, with dense pubescence of same color laterally, and sparse pubescence of same color between sides and central pubescent band. Sides of prothorax with pubescence as in sides of pronotum, gradually, slightly less dense toward prosternum. Ventral surface of thorax with sparse light yellowish-brown pubescence, denser laterally. Scutellum with light yellowish-brown pubescence except glabrous centrobasal area.

Elytra. Sides arched; apex with outer angle forming large triangular projection, and sutural angle forming small triangular projection, with area between them concave; coarsely, sparsely punctate (punctures slightly finer toward apex). Pubescence light yellowish-brown (lighter depending on light intensity), as follows: basal fifth with large, subtriangular macula, reaching humeri, abundant in some areas, sparser in others, not obscuring integument, partially connected along sides of elytra with oblique dense band, not reaching midlength of elytra and suture; oblique row with three spots of dense pubescence, placed dorsally, slightly after middle of elytra; another oblique row with two spots of dense pubescence close to the former; another irregular spot with dense pubescence at distal fifth; remaining surface with very sparse pubescence, slightly more abundant on sides of midlength, and posterior fifth.

Legs. Femora with yellowish-white pubescence (brighter white depending on light intensity) distinctly not obscuring integument. Tibiae with pubescence as on femora; with short, suberect yellowish setae ventrally; dorsal distal third of meso- and metatibiae carinate, with row of thick, erect, short yellow setae, along carina, curved toward outer apex posteriorly. Tarsi with pubescence as on femora.

Abdomen. Ventrites I–IV with dense yellowish-brown pubescence laterally (lighter depending on light intensity), distinctly sparser centrally; V with dense yellowish-brown pubescence throughout (lighter depending on light intensity); apex of ventrite nearly truncate.

Female. Antennae slightly shorter (0.9 times elytral length), almost reaching midlength of elytra; abdominal ventrite V longitudinally sulcate.

Variation. Anteclypeus and labrum dark brown; elytra dark reddish brown, gradually lighter toward apex; tibiae entirely dark brown.

Dimensions (mm), holotype / paratype males/ paratype females. Total length 6.20/6.25–7.25/7.40– 7.40; prothoracic length 1.50/1.50–1.70/1.70; anterior prothoracic width 1.15/1.15–1.35/1.45; posterior prothoracic width 1.30/1.25–1.45/1.55; maximum prothoracic width 1.35/1.30–1.55/1.65; humeral width 1.45/1.40–1.65/1.75; elytral length 4.25/4.20–4.95/5.05.

Type material. Holotype male from MEXICO, Oaxaca: 2 miles north San José del Pacífico, 16.VII.1974, Clark, Murray, Ashe and Schaffner col. ( TAMU) . Paratypes – same data as holotype, 6 males, 3 females (3 males, 2 females TAMU, 1 male, 1 female ACMT, 1 male FSCA, 1 male MZSP) ; 1 male, 20.VII.1974 ( TAMU) .

Remarks. All other species currently placed in Adetaptera have the elytral apex rounded or nearly so. As A. schaffneri sp. nov. has both the lateral and interior margin of the elytral apices with acute spines, it may be better placed in a new genus, however, because the elytral shape by itself does not justify erecting a new genus we have provisionally included it in Adetaptera .

Etymology. Named to recognize and honor Joseph Schaffner, retired Texas A&M University Entomology Professor.
