Eburiola ciferrii Lingafelter , new species

( Fig. 3 )

Diagnosis. This species, like E. konstantinovi Lingafelter , new species, described herein, is distinctive by having paired eburneous elytral spots only at the base and single eburneous spots at the middle and posteromedially on the elytra. The common Eburiola geminata (Fabricius) has only a basal pair of elongate eburneous spots and a medial pair of slightly elongate spots. Eburiola ciferrii has the basal third of the elytra with large, separate punctures, each bearing a single short, stiff, erect seta, and lacking pubescence elsewhere on the elytral base around the punctures. In E. konstantinovi , the elytra, which are relatively longer and narrower, are nearly completely covered with short, suberect pubescence and the punctures are mostly obscured by the pubescence. The metafemora of E. ciferrii are very long and extend beyond the elytral apices by almost half their length, while in E. konstantinovi , they are much shorter and extend beyond the elytral apices by less than one-third their length.

Description. Holotype male. 16.8 mm long; 4.6 mm wide at humeri. Color: Integument piceous to nearly black except for sternites, coxae, femora, protibiae, metepisternum, and frons which are light reddish-brown.

Head. Shallow, evenly concave inter-antennal tubercle region; tubercles only weakly elevated. Head (including antennal tubercles) moderately punctate, mostly glabrous; eyes moderate-sized, coarsely faceted, 9 facets across width of upper lobe, deeply emarginate at insertion of antenna, upper lobes widely separated on vertex by more than gap 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. Antennae of holotype missing terminal 6 antennomeres on right side and 7 on left. End of antennomere 5 nearly attaining elytral apex.

Thorax. Pronotum length slightly less than width; gradually rounded at sides; lacking dorsal and lateral tubercles and completely covered with large, contiguous, deep punctures, most of which bear a single, suberect, piceous seta. Prosternum moderately punctate and gray pubescent. Prosternal process about one-half width of procoxa, slightly expanded at apex, acutely declivous; procoxal cavities widely open posteriorly. Elytra with deep, coarse, separate punctures at basal third, becoming much smaller and denser at middle near suture to apical half. Most punctures each with single, piceous seta emerging at middle, but elytra otherwise glabrous. Elytra with bold, slightly raised yellow-eburneous calli as follows: two paired at middle of base, one large unpaired callus at middle near suture, and one slightly smaller unpaired callus at apical fourth centered on elytron. Elytral calli glabrous except for a few stiff, black setae. Elytral apices sinuate with moderately produced apicolateral projection and acute apicosutural angle, but not spinose. Scutellum triangular, not acute posteriorly, covered in dense, short, dark setae. Legs long; metafemora extending beyond elytral apices by nearly half their length. Meso- and metafemora cylindrical, barely expanded at middle; profemora moderately swollen at middle. Profemoral apices rounded, mesofemoral apices weakly spinose, metafemoral apices strongly spinose. Mesocoxae separated by very broad mesosternal process that is nearly equal to the width of mesocoxa.

Abdomen. Abdominal venter with sparse, translucent setae, otherwise mostly glabrous.

Type material. Holotype (male): “ Haiti: S. Juan di Mag. ” [ DOMINICAN REPUBLIC: San Juan Province, San Juan de la Maguana], 10.V.1928. R. Ciferri ( USNM).

Etymology. This new species is named after the collector of the holotype, Dr. R. Ciferri, former Director of the Moca Agricultural Station in Espaillat Province in north-central Dominican Republic.

Remarks. Although the label says “Is. Haiti, S. Juan di Mag.”, it refers not to Haiti, but rather to the island of Hispaniola and “S. Juan di Mag.” is San Juan de la Maguana in San Juan Province of the Dominican Republic.
