Eburodacrys boteroi sp. nov.

(Fig. 4A–F)

Diagnosis. Each elytron with three elongate eburneous callosities dorsally: one anterior and two posteriors (outermost longer than inner ones); dark area surrounding part of posterior eburneous callosity (Fig. 4A). Sides with longitudinal eburneous macula close to epipleural margin, from humerus to posterior quarter (Fig. 4B). Antennomeres III–VI sulcate dorsally. Mesoventrite without tubercles. Meso- and metafemora subclavate (Fig. 4F); meso- and metafemoral spines black (Fig. 4F); meso- and metatibiae with deep sulcus dorsally.

Description. Holotype female. Integument mostly orange; elytra yellowish, lighter posteriorly; apex of mandible, apex of profemora, spines of meso- and metafemora black, tarsal claws dark brown. Each elytron with three elongate eburneous callosities dorsally: one anterior and two posteriors (outermost callosity longer than inner ones); with dark area surrounding inner margin of anterior callosities and part of posterior callosities (Fig. 4A). Sides with longitudinal eburneous macula close to epipleural margin, from humerus to posterior quarter.

Eyes coarsely faceted (Fig. 4E). Upper eye lobes well separated, distance between them more than 3x width of one upper lobe; upper eye lobe with four rows of ommatidia dorsally, five toward lower eye lobe. Scape subcylindrical, with sulcus on dorsal surface; antennomeres III–VI sulcate dorsally; antennomeres III–VIII with long, erect and sparse setae; antennomeres IX–XI with short pubescence.

Head with transverse wrinkles and shallow punctation on vertex. Prothorax, including lateral tubercles, slightly wider than long; lateral tubercles located centrally (Fig. 4D). Surface of pronotum with two elevated and rounded tubercles slightly before middle (Fig. 4D); with transverse wrinkles and deep punctation. Mesoventrite without tubercles. Elytral surface with sparse, long setae and thick and dense punctation; apex of elytra with short external spine. Legs with long, erect and sparse setae. Profemora fusiform. Meso- and metafemora subclavate and with long inner spine (Fig. 4F). Meso- and metatibiae with deep dorsal sulcus. Abdomen with long, erect and sparse orange setae.

Measurements, in mm. Total length: 9.4; prothorax length: 1.5; anterior width of prothorax: 1.5; posterior width of prothorax: 1.8; elytral length: 6.7; humeral width: 2.1.

Etymology. The specific name is in honor to Dr. Juan Pablo Botero, for his contribution to the study of the tribe Eburiini (Cerambycidae) .

Type material. Holotype female, BRAZIL: “ BAHIA, Ipecaetá, Cavungê, Rancho Alto da Boa Vista, 25.i.2020, Coleta ativa. Ferreira, G.S. Leg. ” (MZFS) (Fig. 4G).

Remarks. Eburodacrys boteroi sp. nov. can be easily differentiated from the congeneric species because it is the only species with the metatibiae with deep sulcus dorsally. Eburodacrys boteroi sp. nov. is morphologically similar to E. catarina Galileo & Martins, 1992 (Fig. 5A), E. eburioides (White, 1853) (Fig. 5B), E. flexuosa Gounelle, 1909 (Fig. 5C), E. lancinata Napp & Martins, 1980 (Fig. 5D), E. lenkoi Napp & Martins, 1980 (Fig. 5E), and E. tuberosa Gounelle, 1909 (Fig. 5F) by the elytra with three elongate eburneous callosities dorsally. However, E. boteroi sp. nov. has pronotal tubercles clearly elevated and the elytral spine on the apex shorter than the femoral spines (Fig. 4D) (pronotal tubercles slightly elevated and elytral apical spines as long as femoral spines in E. eburioides (Fig. 5B)); meso- and metafemoral spines black (Fig. 5G) (meso- and metafemoral spines with the same color of the apical elytral spine in E. flexuosa (Fig. 5C) and sometimes darker in E. lenkoi (Fig. 5E)); spine of the elytral apex short (Fig. 4A) (as long as femoral spine in E. lancinata (Fig. 5D)); pronotum coarsely punctate between the wrinkles (Fig. 4D) and mesoventrite without tubercles (pronotum with wrinkles (Fig. 5A; 5F) and mesoventrite with tubercles in E. catarina and E. tuberosa).

In the key to species of Eburodacrys White, 1853 (modified from Botero, 2017), E. boteroi sp. nov. can be included in the couplet “42”
