Description of female holotype. Head dorsally, and prothorax, dark brown; head ventrally dark reddish-brown; mouthparts reddish-brown; anteclypeus and anterior half of labrum yellowish-brown; posterior half of labrum reddish-brown; scape, pedicel, and antennomeres III–IV dark brown (more dark reddish-brown depending on light intensity), with distal area reddish-brown; remaining antennomeres reddish-brown; ventral surface of meso- and metathorax dark brown (slightly dark reddish-brown in some areas depending on light intensity); scutellum and longitudinal band along elytral suture dark brown; remaining elytral surface reddish-brown except dark brown punctures; femora dark brown (darker reddish-brown in some areas depending on light intensity); tibiae dark brown basally, reddish-brown on remaining surface; tarsi brown (slightly reddish-brown depending on light intensity); abdominal ventrites dark reddish-brown, darker brown centrally in some areas, especially basal half of V.

Head. Frons densely, moderately finely punctate; with short, abundant, moderately narrow yellowishwhite scales nearly obscuring integument (scales slightly yellower or whiter in some areas), except shorter, narrower, sparser scales in central area near antennal tubercles. Vertex moderately finely, densely, shallowly punctate (punctures slightly coarser than on frons and partially confluent); with scales longer than on frons, with similar color, nearly obscuring integument (apparently, part of them lost in area between upper eye lobes), except smaller, sparser scales close to prothoracic margin. Area behind upper eye lobes with sculpturing and scales as on vertex, gradually shorter and sparser toward lower eye lobe. Area behind lower eye lobes moderately coarsely, shallowly, abundantly punctate; with short, narrow, moderately abundant yellowish-white scales (yellower depending on light intensity), partially obscuring integument, except nearly glabrous area close to prothorax. Antennal tubercles with sculpturing and scales as on frons, except smooth and glabrous narrow distal area. Median groove distinct from clypeus to level of posterior margin of eyes, deeper between antennal tubercles and upper eye lobes. Genae finely, moderately abundantly, shallowly punctate; with short, decumbent, narrow, moderately abundant yellowish-white scales. Gulamentum smooth, glabrous posteriorly, moderately coarsely, shallowly, confluently punctate, with narrow, short, bristly yellowish scales, slightly whiter, sparser toward posterior region of punctate area. Postclypeus with sculpturing and scales as on frons posteriorly, with scales gradually slender toward anterior margin; with a few long, erect yellowish setae laterally close to anterior margin. Labrum coplanar with anteclypeus in posterior third, inclined in anterior 2/3; finely, moderately sparsely punctate posteriorly close to boundary of inclined area, smooth on remaining surface; with both, short and long, sparse yellowish setae in punctate area, glabrous on remaining surface. Distance between upper eye lobes 0.83 times length of scape; in frontal view, distance between lower eye lobes 1.05 times length of scape. Antennae 1.2 times elytral length, reaching about posterior ninth of elytra; scape moderately finely, abundantly punctate, with narrow, small, decumbent, moderately abundant whitish scales; antennomeres with short, decumbent whitish scales, gradually

shorter, sparser toward distal segments; outer side of antennomeres III–IV not carinate; outer side of antennomeres V–IX carinate posteriorly (carina slightly increasing in length toward X); outer side of antennomeres X–XI entirely carinate. Antennal formula (ratio) based on length of antennomere III: scape = 0.96; pedicel = 0.23; IV = 0.93; V = 1.16; VI = 0.96; VII = 0.94; VIII = 0.87; IX = 0.83; X = 0.82; XI = 0.98.

Thorax. Prothorax about as long as wide; sides subparallel in posterior third, with large, rounded tubercle about midlength, with distinct constriction between lateral tubercles and anterior quarter, rounded in anterior quarter before narrow constriction near anterior margin. Pronotum coarsely, shallowly, conflu- ently punctate; anterolateral tubercles distinctly elevated; with moderately short, very slightly arched yellowish-white scales, slightly whiter toward posterior margin, moderately yellowish-brown, more abundant laterally in anterior half; with small, decumbent whitish scales close to anterior and posterior margins. Sides of prothorax with sculpturing and scales as on pronotum, interspersed with shorter and narrower whitish scales toward prosternum. Prosternum shallowly, moderately rugose-punctate in posterior 2/3, shallowly, moderately sparsely punctate in anterior third; with moderately short, very slightly arched yellowish-white scales (more yellowish-brown depending on light intensity) in posterior third, distinctly finer, sparser in anterior third; postcoxal processes glabrous except narrow band with small, decumbent, narrow scales close to procoxal cavities. Prosternal process with short yellowish-white scales (more yellowish-brown depending on light intensity), bristly posteriorly. Ventral surface of mesothorax with short, decumbent, moderately narrow yellowish-white scales (more yellowish-brown depending on light intensity), distinctly denser on mesanepisternum and mesepimeron. Metanepisternum, sides and anterior area of metaventrite with short, decumbent, moderately narrow yellowish-white scales (more yellowish-brown depending on light intensity); remaining surface of metaventrite with narrower, sparser whitish scales (slightly yellowish depending on light intensity). Scutellum with very short, decumbent yellowish-white scales except glabrous area close to margins. Elytra. Coarsely, deeply, moderately abundantly punctate in basal half (punctures not aligned in rows, nearly quadrate), gradually finer toward apex; apex obliquely truncate; with moderately narrow, elongate, abundant, decumbent yellowish-white scales ( Fig. 13 , 31 ) (whiter depending on light intensity); with longitudinal row of short, narrow whitish scales along sutural and epipleural margins; with minute yellowish seta in nearly all punctures. Legs. Femora and tibiae with short, abundant, decumbent yellowish-white scales (whiter depending on light intensity); tibiae interspersed with fine yellowish setae ventrally in distal half; ventral surface of protibiae transversely striate.

Abdomen. Ventrites finely, abundantly punctate; with short, decumbent, abundant, narrow yellowish scales (whiter depending on light intensity), slender on V, interspersed with fine, erect yellowish setae on sides and in posterior area of V; apex of ventrite V truncate, very slightly emarginate centrally.

Dimensions (mm). Total length 14.55; prothoracic length 2.20; anterior prothoracic width 1.40; posterior prothoracic width 2.05; maximum prothoracic width 2.20; humeral width 3.55; elytral length 9.95.

Type material. Holotype female from GUATEMALA, Zacapa: Sierra de las Minas ( Cerro del Mono ; cloud forest; 8 road km N San Lorenzo marble mill; 2150 m; MV & UV lights), 7.VI.1993, W.B. Warner col. ( FSCA).

Etymology. Named for Bill Warner, collector of the holotype and a noted student of the Scarabaeidae .

Remarks. Caraphia warneri sp. nov. is similar to C. lingafelteri but differs as follows: body more slender (4.1 times longer than wide); elytral apex obliquely truncate, with outer side distinctly angular ( Fig. 13 ); elytral scales longer, wider, straight and not arched ( Fig. 13 , 31 ); antennae terminating well short of elytral apex. In females of C. lingafelteri the body is wider (from 3.5 to 3.7 times longer than wide), the elytral apex is rounded or slightly obliquely truncate but with outer side not angular ( Fig. 10 ), the elytral scales are shorter, narrower and distinctly arched ( Figs 10 , 30 ), and antennae clearly surpass elytral apex.
