Eburodacrys boteroi View in CoL sp. nov.
( Fig. 4A–F View FIGURE 4 )
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 View FIGURE 4 ). Sides with longitudinal eburneous macula close to epipleural margin, from humerus to posterior quarter ( Fig. 4B View FIGURE 4 ). Antennomeres III–VI sulcate dorsally. Mesoventrite without tubercles. Meso- and metafemora subclavate ( Fig. 4F View FIGURE 4 ); meso- and metafemoral spines black ( Fig. 4F View FIGURE 4 ); 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 View FIGURE 4 ). Sides with longitudinal eburneous macula close to epipleural margin, from humerus to posterior quarter.
Eyes coarsely faceted ( Fig. 4E View FIGURE 4 ). 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 View FIGURE 4 ). Surface of pronotum with two elevated and rounded tubercles slightly before middle ( Fig. 4D View FIGURE 4 ); 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 View FIGURE 4 ). 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 View FIGURE 4 ).
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 View FIGURE 5 ), E. eburioides (White, 1853) ( Fig. 5B View FIGURE 5 ), E. flexuosa Gounelle, 1909 ( Fig. 5C View FIGURE 5 ), E. lancinata Napp & Martins, 1980 ( Fig. 5D View FIGURE 5 ), E. lenkoi Napp & Martins, 1980 ( Fig. 5E View FIGURE 5 ), and E. tuberosa Gounelle, 1909 ( Fig. 5F View FIGURE 5 ) 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 View FIGURE 4 ) (pronotal tubercles slightly elevated and elytral apical spines as long as femoral spines in E. eburioides ( Fig. 5B View FIGURE 5 )); meso- and metafemoral spines black ( Fig. 5G View FIGURE 5 ) (meso- and metafemoral spines with the same color of the apical elytral spine in E. flexuosa ( Fig. 5C View FIGURE 5 ) and sometimes darker in E. lenkoi ( Fig. 5E View FIGURE 5 )); spine of the elytral apex short ( Fig. 4A View FIGURE 4 ) (as long as femoral spine in E. lancinata ( Fig. 5D View FIGURE 5 )); pronotum coarsely punctate between the wrinkles ( Fig. 4D View FIGURE 4 ) and mesoventrite without tubercles (pronotum with wrinkles ( Fig. 5A; 5F View FIGURE 5 ) 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”
