Skelley, Paul E. & Keller, Oliver, 2022, A third species of Haroldiellus Gordon and Skelley, 2007 from Mexico and Central America (Coleoptera: Scarabaeidae: Aphodiinae: Aphodiini), Insecta Mundi 2022 (916), pp. 1-11 : 4-5

Haroldiellus woodruffi Skelley and Keller , new species

Figures 3, 5 , 8–9 , 12–17

Diagnosis. Length 5.3–5.8 mm, width 2.4–2.7 mm. A member of Haroldiellus distinguished from other species by: Elytral intervals convex, striae deeply impressed; interval color pale with distinct diagonal black marking ( Fig. 3 ). Female lacking median frontal tubercle ( Fig. 8 ); male median frontal tubercle transverse and bifid ( Fig. 9 ). Protibia with dorsal surface lacking punctures ( Fig. 5 ).

Description. Male holotype. Length 5.6 mm, width 2.6 mm. Body robust, not flattened. Body ( Fig. 3 , 12–13 ) color dark reddish brown except head and lateral pronotum pale reddish brown; elytra yellowish brown, striae darkened over disk, intervals with an irregular diagonal dark mark notably contrasting with pale part of intervals; legs paler yellowish brown. Dorsal surface glossy; glabrous; body not fimbriate; ventral surface with moderately long, moderately dense pubescence. Anterior clypeal margin with angles rounded, margin between angles thickened, emarginate. Clypeus and epistome coarsely punctured, flat. Frontal suture trituberculate ( Fig. 9 ), median tubercle broad and bifid. Genae moderately developed, slightly deflexed. Pronotum shiny; with intermixed moderate and fine punctures, all punctures separated by 1–2 times their diameter on disc. Scutellar shield weakly pentagonal, not depressed. Elytra with striae deeply impressed, coarsely punctured; intervals convex, glossy, finely punctured. Ventral surface and metafemur with few coarse punctures. Male metaventrite not deeply excavated, without patch or fringe of dense setae. Protibia lacking dorsal punctures ( Fig. 5 ), unmodified; protibial spur and protarsus unmodified. Inferior mesotibial spur straight at apex, lacking tooth. Metatrochanter with a single seta. Metafemur robust, wider than metacoxa; posterior margin of metafemur smooth, glabrous. Metatibia robust, apically flared, not compressed; apex of metatibia fringed with short, equal spinules. Metatarsus as long as metatibia, tarsomeres slender, cylindrical, with basal tarsomere as long as superior tibial spur, slightly longer than tarsomeres 2 and 3 combined. Epipharynx transverse, side rounded, anterior margin concave towards middle; epitorma conical; corypha slightly protruding, with apical clump of long, slender celtes; pedia pubescent, with several stout, scattered chaetae; chaetopariae moderately dense, moderately elongate ( Fig. 14 ). Male genitalia unmodified; parameres slightly widening at apex, without membranous appendage ( Fig. 15–16 ).

Female allotype. Length 5.3 mm, width 2.4 mm. Body more elongate, less robust than male; median frontal tubercle reduced to simple swelling ( Fig. 8 ).

Variation. Paratypes show some variation in the thickness of the black elytral markings, but they are always well-defined.

Distribution. ( Fig. 17 ). Mexico (Chiapas), Guatemala (El Progreso, Guatemala, San Marcos), Costa Rica (San José), Panama (Chiriqui).

Etymology. This species is named after Robert Woodruff, friend and mentor, who first studied this species and recognized it as something different, but near H. sallei .

Remarks. Haroldiellus woodruffi , like H. lansbergei , appears to be a species occupying higher elevations.
