Cyclocephala everardoi sp. nov.
( Figures 1 View FIGURE 1 G, 2A–E)
Material examined. Holotype male labeled: “ Brasil, MG, 8 km ao N de/Cristália, 16.ii.2010, luz/ 16o39'S, 42o53'W, 720m,/Grossi, Parizotto & Melo/ao amanhecer (5–6: a.m.)” ( CERPE).
Holotype male. Total length: 9.01 mm. Total pronotal width: 3.59 mm. Body: Dorsal surface glabrous, ventrally densely setose, setae distinctly elongate. Color brownish red, with lighter areas on clypeal apex, pronotum, scutellum ( Fig. 2 View FIGURE 2 A), legs, and venter. Head: Shape transverse with abrupt narrowing to clypeus, sparsely punctate; punctures larger on clypeus and on sides; clypeus narrowly parabolic, ⅓ of head width, with elongated punctures, anteriorly concave, and with C–shaped punctures, apex reflexed and bordered ( Fig. 2 View FIGURE 2 B). Frontoclypeal suture obsolete at middle, with 2 lateral, transverse impressions. Antennae with lamellae extremely developed, almost 3x longer than antennomeres 3–7 together, and strongly and densely punctate with a spongiose aspect, and with scattered setae ( Fig. 2 View FIGURE 2 C); first lamella externally with longitudinal row of dense setae; eyes large, wider than clypeal width ( Figs 1 View FIGURE 1 G–2B). Mouthparts: Mandibles slender, apices upturned and externally curved and with elongated setae, basal half laterally crenulated; last maxillar palpomere slightly longer than the preceding 2 together. Pronotum: Surface weakly and sparsely punctate, punctures stronger posteriorly; posterior margin slightly projected backward, rounded, with no bead; sides with long setae, weakly crenulated. Scutellum punctate; punctures small to large, some elongate. Elytra: Surface distinctly and irregularly punctate; striae not well defined, slightly wrinkled near suture. Legs: Protibiae with 3 distinct teeth, teeth decreasing in size from apex to base; apical tooth twice as long as middle tooth, middle tooth more than 3x longer than basal tooth ( Figs 2 View FIGURE 2 A–B); inner claw widely bifid, forming a right angle ( Fig. 2 View FIGURE 2 D). Venter: Anterior prosternal margin sinuous and crenulated by setae insertion, distinctly trilobed at middle, with lateral lobes more prominent than middle lobe, conspicuous ( Fig. 1 View FIGURE 1 G). Prosternal process high, exceeding coxal height. Genitalia: Parameres symmetrical with elongated parameres, with 2 lateral projections, one basal and one at middle; basal larger, middle one projecting backwards; apices diverging internally, externally with small serrations; subapex with a slightly diverging, rounded tooth at external angle ( Fig. 2 View FIGURE 2 E).
Etymology. This species is named in honor of the dedicated entomologist, Everardo José Grossi, father of the first author, a doctor with a passion for beetles and an expert in rhinoceros beetles.
The specimens were collected with UV light. Cyclocephala everardoi sp. nov. was taken at dawn in February 2010, between 5:00 and 6:00 A.M., in an area of sandy and rupestrian Cerrado fields ( Fig. 3 View FIGURE 3 A). Cyclocephala machadoi sp. nov. lacks other information. Both holotypes are pinned; in C. everardoi sp. nov. part of the middle tooth of left protibia is missing, while in C. machadoi sp. nov. part of the right first and second antennal lamellae are missing. They were initially confused with Cyclocephala macrophylla Erichson 1847 . Cyclocephala machadoi sp. nov. is similar to C. everardoi sp. nov. and was also confused with this. In comparing them, we concluded that they were similar but distinct species and they are diagnosed in the Table 1 View TABLE 1 . We also believe that they compose a new species group within Cyclocephala , being diagnosed by the short body length, extremely elongate antennal lamellae, eyes very developed, clypeus elongate and truncate, somewhat quadrate and inner claw of anterior tarsi with a wide incision.
TABLE 1. Main characters to differentiate the two new species of Cyclocephala described here.
| Character | C. machadoi sp. nov. | C. everardoi sp. nov. |
|---|---|---|
| Color | Testaceous with black head | Brownish red |
| Clypeus | Almost impunctate, strongly reflexed. | With elongated and C–shaped punctures, slightly reflexed |
| Frontoclypeal suture | Obsolete, lacking impression | Obsolete at middle and with two transverse impressions |
| Pronotum | Surface moderately and uniformly punctate, smooth at center line | Surface weakly and sparsely punctate, punctures posteriorly stronger |
| Elytra | Striae distinct, marked by lines of punctures; interstriae almost impunctate | Striae indistinct and surface nearly totally, uniformly punctate |
| Protibiae | Basal tooth weak, and more than 3x smaller than middle tooth | Basal tooth more developed, and distinctly projected, three times smaller than middle tooth |
| Aedeagi | Parameres with apices parallel; middle tooth small, projecting laterally | Parameres with apices diverging; middle tooth more developed, projecting backwards |
