Figs 1 –2

Description. FEMALE: Length, 28–32 mm. Form robust, slightly tapering posteriorly; integument shining, all black except for two, yellow, transverse fasciae of elytra; pubescence sparse, long, erect, short, pale, dense at sides of mesometasterna and abdomen. Head small; front short, deeply impressed transversely, each side of glabrous area with deep pit, median line deep, extending onto vertex between a swollen area between eyes; mandibles arcuate, acute at apices; palpi short, apical segments of labial palpi rounded at apex, maxillary palpi truncate at apices, impressed dorsally; genae small, subtruncate at apices; antennal tubercles broad, moderately elevated, apices rounded; eyes moderately large, finely faceted, upper lobes small, well separated; antennae 11-segmented, slender, shorter than body, scape conical, sparsely, finely punctate, carinate over basal ½, segments from fourth densely clothed with very short, appressed, pale pubescence, basal segments with a few, short, erect, black hairs beneath, segments 3–11 laterally carinate, 3 & 4 slightly enlarged at apices, third segment subsequal to first, fourth shorter (7/10 of third), fifth to seventh subequal (8/10 of third), eight subequal to fourth, ninth to tenth successively shorter than eight, eleventh appendiculate, subequal to ninth. Pronotum broader than long, sides with large, narrowly obtuse tubercles slightly behind middle; disk with two, vaguely elevated, glabrous calluses behind apical margin and three, vague calluses behind middle, one median two lateral, basal margin broadly impressed; sides at apical ½ coarsely, confluently punctate, dorsal punctures coarse, confluent, basal 1/3 almost impunctate, pubescence sparse, pale, long, erect; prosternum coarsely, confluently, punctate above coxae, pubescence pale, erect, intercoxal process narrower than coxal cavities, arcuate, abruptly declivous behind, coxal cavities wide open behind; mesosternum with intercoxal process narrower than coxal cavities, very prominently produced with blunt apex, abruptly, concavely declivous anteriorly, sides very finely clothed with short, silvery pubescence; metasternum very finely pale pubescent at sides. Scutellum glabrous, acutely pointed apically. Elytra about twice as long as broad, wrinkled at base, sides slightly tapering; punctures very fine, sparse, becoming obsolete toward apex; pubescence obsolete; disk with a broad, yellow, transverse fascia at basal ½ and another, narrower yellow fascia behind middle; apices obliquely sinuate-truncate, margins slightly dentate. Legs slender; hind femora linear, not extending beyond body, finely, sparsely punctate; tibiae slender, apically with two short spines, internally with a row of short, suberect hairs; meta-tarsi slender, first segment about as long as two following together, third segment cleft to base. Abdomen finely pubescent at sides; fifth sternite broadly rounded at apex.

MALE: Length, 20 mm. Form moderate-sized. Integument shining, black, parts of pronotum, femora, and abdomen partially dark reddish-brown. Labial and maxillary palpi short, apical segment of labial palpi truncate at apex, maxillary palpi pointed at apices. Antennae, extending about 3 segments beyond elytra, segments 3 & 4 slightly enlarged at apices, remaining segments laterally carinate, third segment longer than first, fourth subequal to first, fifth subequal to third, eleventh appendiculate. Pronotum less robust than female, sides with small, narrowly obtuse tubercles slightly behind middle; disk with two, moderately elevated, glabrous calluses behind apical margin and three, more vague calluses behind middle, one median two lateral, sides at apical ½ densely, confluently punctate, dorsal punctures very sparse, located around premedian calluses, basal ½ almost impunctate; prosternum narrow, each side above coxae with a narrow, transverse, finely deeply punctate area (“prosternum with sexual punctures reduced in female”). Elytra about 2.4 times longer than broad; apices obliquely subtruncate, sutural angles rounded. Legs with hind femora extending slightly beyond body. Abdomen with segments 1-4 narrowly black at apices; fifth sternite broadly subtruncate at apex, shallowly emarginated medially.

Etymology. Named for the yellow fasciae of the elytra.

Types. Holotype, female, COSTA RICA, Guanacaste Prov., Estacion Pitilla, 9 km S Santa Cecilla, GNP Biodiversity Study, Jun l989. Other paratypes, all from Costa Rica listed by Chemsak & Hovore, which were not examined by the authors of this paper include: 1 male, Puntarenas Prov., Cerro Nara, 11 Feb 1972, S. Medina Goud (original holotype, see “Remarks” below); 2 female paratypes from COSTA RICA: Alajuela Prov. Sect. San Ramon de Dos Rios, 620 m, 18 Mar- 13 Apr 1995, F.A. Quesada, 3-24 Apr l995, M. Chincilla; and one female paratype from Guanacaste Prov., Estacion Pitilla, 9 km S Santa Cecilla, Mar 1989. Two additional female paratypes not listed by Chemsak & Hovore include: COSTA RICA, Alajuela Prov. 22 km N San Ramon, La Montana Camp, 3000’, 15-26 Jun 2010,W.H. & J.S. Tyson; and PANAMA, Chiriqui, no additional data. Holotype deposited at INBIO. Paratypes in WHTC and MNRJ.

Remarks. The original holotype described by Chemsak & Hovore in their draft manuscript was a male from COSTA RICA: Puntarenas Prov., Cerro Nara, 11 Feb 1972, S. Medina Goud. However , this original holotype male, allotype and other paratypes quoted by Chemsak & Hovore were all missing from the Essig Museum. Therefore, the single remaining female paratype from Guanacaste Province, as described above, was used to represent the holotype of this species. The female characters as provided by Chemsak & Hovore were substituted for the male characters found in their original draft manuscript. All descriptions of characters from the draft manuscript and as provided above for this species were verified.

The female paratype from Alajuela Prov., 22 km N San Ramon, exhibited the following behavior according to W.H. Tyson: “Female sat on the upper limbs of a tree (25’ high) with clusters of drooping yellow flowers. She made numerous flights of 20-30’ out away from the tree, turned, and returned to either the same limb end or one nearby, and not to the flowers.”
