Tibiae gradually dark reddish brown toward apex. Ventral surface of abdomen dark reddish brown basally, gradually lighter toward apex.

Head. Frons somewhat coarsely, abundantly punctate, except smooth central plate close to postclypeus; with short, bristly yellowish-white seta emerging from each puncture, except one thick, short, yellowish seta on each side near eyes, and glabrous on smooth plate. Antennal tubercles finely, sparsely punctate, except smooth apex; with short, decumbent yellowish-white seta emerging from nearly all punctures, except glabrous apex. Vertex and area behind eyes, coarsely, densely punctate, except almost smooth narrow area close to posterior area of eyes; with short, bristly yellowish-white seta emerging from nearly all punctures on area between antennal tubercles and upper eye lobes, distinctly shorter between posterior margin of eyes and prothorax, except almost glabrous smooth area close to eyes; with one somewhat long, erect, thick yellowish seta on each side close to eyes. Area behind lower eye lobes smooth, glabrous close to eye, striate-punctate close to prothorax; with row of short yellowish-white setae close to smooth area, from middle to near inferior area; another row of similar setae close to eye on ventral surface.

Gulamentum smooth, glabrous on posterior area; coarsely rugose-punctate between eyes (less so centrally), with short, bristly, sparse yellowish-white setae laterally, almost absent centrally; intermaxillary process with one long, decumbent yellow seta on each side, directed toward center. Maxillary palpomere IV and labial palpomere III securiform. Posterior 2/3 of outer side of mandibles coarsely, abundantly punctate on its superior area, smooth inferiorly; punctate area with short yellowishwhite setae not obscuring integument, and long, thick yellow setae interspersed, and smooth area glabrous; anterior third smooth and glabrous. Distance between upper eye lobes 0.29 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.31 times distance between outer margins of eyes. Antennae 1.85 times elytral length, reaching elytral apex at basal third of antennomere IX. Scape somewhat coarsely, densely punctate, except smooth apex (smooth area wider dorsally); with yellowish pubescence not obscuring integument, except glabrous smooth area, and a few thick, long, erect yellow setae interspersed. Pedicel and antennomeres III–XI with yellowish pubescence, shorter and denser toward distal antennomeres; pedicel and antennomeres III–IV with long, erect yellowish-brown setae ventrally, sparser on IV; apex of antennomeres III–X with long, sparse yellowish-brown setae directed backward (shorter and sparser toward X); antennomeres III–VI ( Figs 10–13 ) with short spine at inner apex (spine gradually shorter toward VI); antennomere VII with spicule at inner apex; outer apical angle of antennomeres III–IV rounded; outer apical angle of antennomeres V–X angular. Antennal formula based on length of antennomere III (excluding apical spines): scape = 0.87; pedicel = 0.19; IV = 0.81; V = 1.04; VI = 1.04; VII = 1.04; VIII = 0.93; IX = 0.93; X = 0.74; XI = 0.93.

Thorax. Prothorax slightly wider than long; sides rounded from anterolateral angles to near posterolateral angles. Pronotum slightly convex, coarsely, densely punctate, without smooth central area; with somewhat long, decumbent light yellowish-brown setae on basal half of wide central area, shorter, slightly more abundant on posterior half of wide central area; with a few long, erect yellowish setae interspersed on wide central area; with large, dense yellowish-white pubescent macula on sides of anterior half, with yellowish pubescence interspersed; sides of posterior half with decumbent, somewhat short, sparse yellowish setae, and yellowish-white setae interspersed, except area close to posterior margin with white pubescence not obscuring integument. Sides of prothorax coarsely, abundantly punctate; with short, decumbent yellowish-white setae not obscuring integument (appearing to be whiter depending on light intensity). Prosternum coarsely, abundantly punctate on posterior 3/4, slightly rugose-punctate on anterior quarter; with decumbent yellowish-white setae not obscuring integument on posterior 3/4 (appearing to be white depending on light intensity), and a few long, thick yellow setae interspersed; central area of anterior quarter with short, yellowish-white setae not obscuring integument (appearing to be white depending on light intensity) and remaining surface almost glabrous. Narrowest area of prosternal process 0.12 times procoxal width. Procoxal cavities open behind. Mesoventrite with sparse yellowish-white setae, except apex of sides with abundant setae; mesanepisternum, mesepimeron, metanepisternum, and sides of metaventrite with abundant yellowish-white pubescence (appearing to be white depending on light intensity); remaining surface of metaventrite with yellowishwhite pubescence gradually sparser toward central area. Scutellum with dense yellowish-white pubescence, except nearly glabrous anterocentral area. Elytra. Coarsely, abundantly punctate on basal third, punctures gradually finer toward apex; apex slightly obliquely truncate; with slightly oblique, dense white pubescent band before middle, from epipleural margin to near sutural margin; with transverse, irregular, dense white pubescent band on posterior third, from near epipleural margin to about middle of dorsal surface; white pubescent bands with erect yellowishbrown setae interspersed; remaining surface with decumbent yellowish-brown setae not obscuring integument, and long, thicker setae of same color interspersed, and white setae interspersed basally, laterally, and apically (more abundant basally). Legs. Femora with yellowish-white pubescence not obscuring integument, and long, decumbent yellowish-brown setae interspersed dorsally, especially on posterior third of pro- and mesofemora, and posterior 2/3 of metafemora. Tibiae with short yellowish-white setae not obscuring integument, and long, thick yellowish-brown setae interspersed (more abundant on metatibiae), except ventral and lateral surfaces of posterior third of protibiae, and ventral surface of posterior quarter of meso- and metatibiae with bristly, dense yellowish-brown pubescence (denser on protibiae). Metatarsomere I as long as II–III together.

Abdomen. Ventrites with decumbent yellowish-white setae not obscuring integument, and long yellowishbrown setae interspersed, except glabrous apex of ventrites 1–4. Apex of ventrite 5 rounded.

Dimensions (mm). Total length, 8.80; prothoracic length, 1.60; anterior prothoracic width, 1.20; posterior prothoracic width, 1.45; maximum prothoracic width, 1.75; humeral width, 2.15; elytral length, 5.50.

Type material. Holotype male from NICARAGUA, Granada: Las Plazuelas , 11.12. IV.2011, E. van den Berghe leg. ( FSCA) . Paratype male, same data as holotype ( RFMC) .

Etymology. The species is dedicated to Eric van den Berghe, collector of the holotype.

Remarks. Anelaphus erici sp. nov. is similar to A. albopilus Chemsak and Noguera, 2003 (see photographs on Bezark 2021a), but differs by the slender body (stouter in A. albopilus ), the inner spines of antennomeres shorter (longer in A. albopilus , especially of antennomeres III and IV), and the head without dense yellowish-brown pubescence on frons (present in A. albopilus ). It differs from A. yucatecus Chemsak and Noguera, 2003 by the slender body (stouter in A. yucatecus ), the inner spines of antennomeres shorter (longer in A. yucatecus , especially of antennomeres III and IV), presence of a distinct transverse pubescent band on the posterior third of the elytra (not present in A. yucatecus ), and posterior quarter of the elytra without irregular maculae of yellowish pubescence (present in A. yucatecus ). Anelaphus erici also differs from A. undulatus ( Bates, 1880) by the absence of four pubescent maculae on the pronotum (present in A. undulatus ).
