description: Ageniella (Ageniella) domingensis (Banks, 1944)   
(Figs 1E–F, 4E–F, 9A–C)  
 Priocnemella domingensis Banks, 1944, Bulletin of the Museum of Comparative Zoology, 94: 167–187. [Holotype: ♀, DOMINICAN REPUBLIC (MCZC)].   
 Diagnosis. This species can be separated from the other Ageniella species in the Dominican Republic by having bluish-green-purple metallic integument and large body size (Figs 4E–F). Additionally, the antenna is black, the scape and pedicel have bluish-purple reflections; the pubescence on the body is long and black; the first metasomal segment is not carinate; and the fore and hind wings are darkened with bluish-purple reflections. Also, the female has the clypeus large and trapezoidal with a median small tooth (Fig. 1E), and the dorsal face of the hind tibia has thin and small spines. The male has dorsal face of the hind tibia not spinose, and the clypeus is large and trapezoidal, without a median small tooth (Fig. 1F).   
 Description. Male (hitherto unknown). Body length 11.00 mm. Fore wing 9.70 mm; maximum wing width 2.90 mm.   
 Coloration. Head black with faint blue-purplish reflections; clypeus black with blue-purple reflections; mandibular and maxillary palpi dark brown; mandible black with blue reflections from base to half its length, brown apically; antenna black, scape with blue reflections; pronotum and mesosoma black with bluish-purple reflections; metasoma, trochanter, femur, and tibia metallic blue with purple reflections; wing subtranslucent with slight blue reflections, veins dark brown; coxae and tarsi black with blue reflections.   
 Head (Fig. 1F). Head wide; TFD 1.09 × FD, MID 0.61 × FD. Ocelli in acute angle; lateral ocelli closer to each other than to compound eyes; POL 0.90 × OOL. Mandible slender, with two sharpened apical teeth; pubescence on mandible long, abundant on entire surface. Clypeus truncate, large; LC 0.66 × WC; clypeal projection like a tooth absent medially; dorsal surface not slightly convex laterally; anterior margin polished, straight, thin. Maxillary beard with few, not thick, long setae. Antenna elongate; length of fourth segment 0.45 × width; ratio of the first four antennal segments 11:4:21:21, WA3 0.24 × LA3; LA3 1.05 × UID.   
 Mesosoma (Fig. 4F). Pubescence sparse, long, black; punctuation inconspicuous. Pronotum not elongated, width 3.42 × length, posterior margin semi-angulated; pronotal collar short, almost absent. Notauli present on very beginning of mesonotum. Postnotum striated. Propodeum punctuate; propodeal disc covered by long and short setae, propodeal disc areolate, setae long, abundant on inferior corner. Wing long; length of first radial 2 cell 0.60 × distance from its origin to wing apex; third radial sector 1.40 × longer than second; 2m-cu vein slightly curved, meeting third radial sector 0.50 × distance from base to apex of cell. Spines absent on anterior and posterior margins of front tibia; spines on mid tibia, sparse, short, thin, sharpened; hind tibia spinose dorsally, spines short, sharpened, dispersed; tibial brush thin, complete.   
 Metasoma. Metasoma coriaceus, covered by short, abundant setae; terminal metasomal sternum with few, sparse, long setae; metasoma 1.30 × as long as mesosoma.   
 Genitalia (Figs 9A–C). Parapenial lobe split; lobes finger-like, thin, long, their length 0.51 × total genitalia length; apical lobe semi-angulated, curved; basal portion wider. Digitus wide, truncated, punctuated; length 0.55 × paramere length; dorsal lobe longer than ventral lobe, broad, truncate; setae short, scarce; ventral lobe spatulate, short, truncate. Aedeagus thin, long, almost as long as parapenial lobe, sides apically divergent, apex sharpened. Paremere length 0.62 × total genitalia length; two short, rounded expansions on 0.33 and 0.50 of paramere length from the base; apex lanceolate; setae short, thick, covering 0.33 of length apically. Subgenital plate wide, rectangular; apex truncated; setae apically scarce, short, thin.   
 Variation. Some specimens have the mesosoma with stronger blue reflections than in others.

 Distribution. Dominican Republic.   
 Host. Unknown.   
 Remarks. To our knowledge, this species was previously known from the Dominican Republic only from two females collected southeast of Constanza, Santo Domingo (Banks 1944). Herein, we report 10 females from different localities, and four males from San Juan, which are described for the first time. The sexes of A. domingensis were associated by the collection locality and by morphology. Three males were collected in yellow pan traps along with six females in the same locality of San Juan. Moreover, both sexes of A. domingensis are distinct from the other Ageniella by being large and by having strong metallic blue coloration. This species is endemic to the Dominican Republic (Perez-Gelabert 2008).
