The New World species of Bohayella Belokobylskij, 1987 are revised based on morphological data, and a new species of the genus from Ecuador is described: Bohayella rodrigodiazi Kang, sp. nov. This work includes an updated identification key to species of Bohayella in the New World along with images of diagnostic characters. The number of recorded Bohayella species in the New World is increased from two to three.

Ecuador has 228 braconid species recorded (
Specimens for this project were borrowed from the Texas A&M University Insect Collection (
Morphological characters were examined using a Leica MZ75 stereomicroscope. Morphometric characters were measured using Adobe Photoshop CS 6 (Adobe Systems, Inc). Numbers in parentheses in a species description indicate 0.01 × the actual size of each body part. The unit of length used in the current work is mm.
Morphological terms and terms for wing venation used are largely based on those of
Images were initially captured using a Visionary Digital BK Plus imaging system (Dun, Inc.), equipped with a Canon EOS 5DS DSLR camera. Image stacking was performed using Zerene Stacker v.1.04 (Zerene Systems LLC.). Images were edited using Adobe Photoshop CS 6 or Adobe Photoshop CC 2019 (Adobe Systems, Inc), and image plates were generated using the same software.

Holotype Costa Rica • ♀; Heredia, 3 km S. Puerto Viejo OTS, La Selva; 100 m; Oct.1992; P. Hanson leg.; Huertos, Malaise trap set by G. Wright. Paratypes Costa Rica • 1 ♀; same data as for holotype; Nov. 1992 • 1 ♂; same collecting data as for preceding; 10°26'N, 84°01'W; 4, Apr. 1987; H. A. Hespenheide leg.
Specimens of B. geraldinae are distinguished from Old World members by having angled RS and acute apical tooth on claws, and the members of B. geraldinae are distinct from the members of B. rodrigodiazi sp. nov. by having scutellar sulcus with one median crenula; apical maxillary palpomere as long as penultimate maxillary palpomere; median length of T1 ~5.10 × longer than apical width; T2 medially 0.21 × longer than T1; metasomal tergites generally pale but melanic apically.

B. rodrigodiazi sp. nov. is known only from Sacha Lodge, Rio Napo, Sucumbíos, Ecuador at the elevations of 220m and 270m.
This species is named in honor of Dr Rodrigo Diaz, Associate Professor of biological control in the Department of Entomology, Louisiana State University. He is the PhD advisor of the author of this paper (IK) and originally from Quito, Ecuador.
Bohayella rodrigodiazi sp. nov. is the third species of Bohayella recorded from the New World. The three species of New World Bohayella have similar body coloration, but their dorsal metasomal colors are diagnostic and may be correlated to the altitudes of their habitats. Specimens of B. geraldinae collected at altitudes of ~100m possess the palest tergites among the three species. Specimens of B. rodrigodiazi sp. nov. collected at the altitudes of ~250m have darker tergites than the members of B. geraldinae and paler tergites than specimens of B. hansoni. Specimens of B. hansoni collected at the altitudes above 1,500m possess the darkest tergites of the three species. This corresponds with the observations by
First of all, IK would like to thank Dr Michael Sharkey, academic father, for his continuous advice. Also, IK is grateful to Drs Scott Shaw in
