Eburiola konstantinovi Lingafelter , new species

( Fig. 4)

Diagnosis. This species, like E. ciferrii Lingafelter , new species, described above, is distinguished from the common E. geminata (Fabricius) by having paired eburneous elytral calli only at the base and single rounded eburneous calli at the middle and posteromedially. It is distinctive by having the elytra nearly completely covered with short, suberect pubescence and the punctures are mostly obscured by the pubescence. In E. ciferrii , the basal third of the elytra have large, separate punctures, each bearing a single short, stiff, erect seta, and lack pubescence elsewhere at the base around the punctures. The metafemora of E. konstantinovi are short and extend beyond the elytral apices by less than one-third their length while in E. ciferrii , they are very long and extend beyond the elytral apices by almost half their length.

Description. Holotype male. 14 mm long; 4 mm wide at humeri. Female paratypes (2): 13–17 mm long; 3.3–4.4 mm wide at humeri. Color: Integument of head, pronotum, elytra, and venter variably reddish-brown to piceous. Pronotum with at least middle part of disk reddish-brown and piceous elsewhere; elytra lighter reddish-brown at base and darker toward apex; femora light reddish to dark reddish-brown.

Head. Shallow, evenly concave inter-antennal tubercle region; tubercles weakly elevated. Head (including antennal tubercles) moderately punctate, with fine, pale pubescence; eyes moderate-sized, coarsely faceted, 7–8 ommatidia across width of upper lobe, deeply emarginate at insertion of antenna, upper lobes widely separated on vertex by distance between antennal tubercles, lower lobe occupying most of head thickness. Antenna without spines, with sparse, short, appressed setae becoming longer toward apices of each antennomere and sparsely along venter of antennae. Antennae extending beyond elytral apices by 5 antennomeres in male and 2–3 in female. Terminal antennomere over twice as long as scape in male and about as long as scape in female.

Thorax. Pronotum length slightly less than width; gradually rounded at sides; lacking dorsal and lateral tubercles in males; small, acute lateral tubercles present in females. Pronotum with variably sized, irregularly contiguous and separate punctures, most of which bear several short, fine, white setae. Prosternum moderately punctate and white pubescent. Prosternal process moderately wide between procoxae, about one-third width of procoxa, protuberant at apex beyond plane of procoxae; procoxal cavities widely open posteriorly. Elytra with small, shallow punctures densely distributed but separate and mostly concealed by vestiture of short, suberect, dense white and black pubescence. White pubescence most prevalent along suture and apical third; black pubescence most prevalent on basal two-thirds. Elytra with bold, slightly raised yellow-eburneous calli as follows: 2 elongate and paired at middle of base, 1 large unpaired callus at middle slightly closer to suture, and 1 slightly smaller unpaired callus at apical fourth slightly closer to outside edge. Elytral calli glabrous except for a few stiff, black setae. Elytral apices obliquely angled with acute or rounded apicolateral projection, not spinose. Scutellum triangular, not acute posteriorly, covered in dense, short, white setae. Legs moderate in length; metafemora just barely extending beyond elytral apices. Meso- and metafemora cylindrical, not expanded at middle; profemora weakly swollen at middle. Profemoral apices rounded, mesofemoral apices moderately spinose, metafemoral apices strongly and evenly spinose on apices in male; strongly but asymmetrically bispinose in females with mesal spine at least twice the length of outer spine. Mesocoxae separated by very broad mesosternal process that is greater than the width of mesocoxa.

Abdomen. Abdominal venter with sparse, white and translucent setae.

Type material. Holotype (male): DOMINICAN REPUBLIC: Pedernales Province, Sierra de Baoruco, Las Abejas , 18°09.011′N, 71°37.342′W, 1150m, 17 July 2006, A. Konstantinov ( USNM) GoogleMaps . Paratypes (two females): DOMINICAN REPUBLIC, Barahona Province, 18 km from Cabral, off Polo Road, 2.5 km SE Montear Nuevo, 18°06.452′N, 71°14.717′W, 1020 m, 26 July 1999, M. A. Ivie, K. A. Guerrero, Coffee - Magnoliaceae forest ( WIBF).

Etymology. This species is named for Alexander Konstantinov, my friend and colleague who collected the holotype.

Remarks. This species is known only from the Sierra de Baoruco in southwestern Dominican Republic. Nothing is known of the habits or host plants. All three specimens were collected in July.
