Atomosia jimagua View in CoL sp. nov.

( Table 1, Figs. 18–22)

Because A. jimagua is quite similar to A. jagua , only significant differences are given in the following description.

Male. Black, white setose, black legs; spur-like flagellar notch and long sensory pad. Measurements, body 7.3–8.3 mm; wing 6.0–7.0 mm. Head: Scape 1/3 longer than pedicel, flagellum ( Fig. 18) about 1/4 or 1/3 longer than pedicel and scape combined; flagellum incised at apical 1/4, dorsal corner long, spur-like, spine below as long or shorter than spur, sensory area elongate, at least 1/2 as long as flagellum. Ocellar tubercle with 2 long, apically diverging, white setae.

Thorax: Anatergal bristles usually mixed black and white, sometimes entirely black or white. Long pleural bristle usually white, sometimes black.

Wing: Cell r 5 narrowly open at wing margin, never petiolate, diameter slightly greater that length of r-m. Crossvein r-m just before or at middle of cell d.

Legs: Black, narrow apices of femora, narrow bases of tibiae, yellowish or reddish; vestiture whitish, hind tibia with sparse black bristles. Tarsi with black vestiture; fore and middle basal tarsomeres with 2 whitish bristles, setae usually black dorsally.

Abdomen: About twice as long as scutum and scutellum combined; tergites 1–3 with sparse whitish bristles laterally; tergite 7 short, strap-like, about 1/4 as long as wide.

Terminalia ( Figs. 19–22): Gonocoxa narrow apically. Aedeagus with lateral apodemes separated, trifid distiphallus decumbent, ejaculatory apodeme strongly curved forward, capitate apically. Hypandrium triangular.

Female. Measurements, body 7.4–8.5 mm; wings 6.2–8.7 mm.

Types. DOMINICAN REPUBLIC: Pedernales prov. PN Jaragua / trail to Carlitos ca. 6 km S of / Highway 44, 106 meters / 17 o 48.932'N o 71028.271'W / 8 July 2004 N. E.Woodley (♂ holotype, USNM) . Paratypes, same data as holotype (2 ♀, USNM) ; prov. Pedernales / 13.5 km N Cabo Rojo, 140 m / cactus-thorn scrub, flight / intercept trap, M.A. Ivie, / T.K. Philips & K.A. Johnson ~ 21 AUG-10 / SEP 1988 (3 ♂, 1 ♀, MAIC) ; prov. Pedernales / 13.5 km N. Cabo Rojo , 140 m / 21 AUG10-SEP1988 flight / intercept trap, M.Ivie, / T.K.Philip & K.A.Johnson (2 ♂, MAIC) ; prov. Pedernales 24 km N. Cabo Rojo , 610 m / Aug 19 1988, wet forest / M.Ivie, Philips & Johnson (2 ♂, 2 ♀, MAIC) ; Pedernales prov. S. / end of Lago de Oviedo / 26.v.1986, R.Miller / & L.Stange (3 ♂, FSCA) .

Distribution. Pedernales province in the Dominican Republic. Captured during May and August-September in cactus-thorn scrub vegetation at low elevations (106–140 m) and in wet forests at higher elevations (610 m).

Etymology. From the Taino language, jimagua meaning 'twins, those that are very similar', referring to the fact that A. jimagua and A. jagua are very similar species.

Remarks. Atomosia jimagua runs to A. danforthi in Curran's key (1935) but is distinguished by the darker legs and white setae on the thoracic and abdominal dorsum. It differs from A. jagua by the characters discussed in the remark section of that species.
