Elmohardyia nicaraguensis Rafael , n. sp.

( Figs. 1–7 )

Diagnosis. Scape and pedicel dark brown to black, flagellum yellow. Third costal section about as long as fourth. Abdomen gray pruinose on tergite 1, anterior and posterior border of tergite 2 and posterolaterally on tergites 3–5. Syntergosternite 8 with small membranous area. Inner surstylus strongly developed, longer than outer surstylus. Phallic guide with external side extremely developed.

Description. Male: body length 4.5 mm; wing 5.6 mm. Eyes holoptic for a distance of six facets. Frontal triangle and face with gray pruinosity. Scape and pedicel dark brown to black, flagellum yellow. Scutum and scutellum dark brown to black, brown pruinose. Notopleuron, postpronotal lobe and mesopleuron gray pruinose, except mesopleuron near mid and hindcoxae shining, without pruinosity in certain lights. Scutellum with inconspicuous bristles. Legs yellow, except coxae brown and distal tarsomeres brown. Wing with third costal section as long as fourth; vein r­m placed near basal third of cell dm. Halter with stem yellow, knob brown to black. Abdomen ( Fig. 1 ) dark brown to black, subshining, gray pruinose on tergite 1, anterior and posterior border of tergite 2 and posterolaterally on tergites 3–5; tergite 1 with 1–2 black bristles laterally. Syntergosternite 8 black, longer than tergite 5, with small membranous area. Sternites 6 and 7 gray pruinose. Epandrium and surstyli ( Fig. 2 ) yellow. Surstyli asymmetrical, the inner strongly developed, longer than outer surstylus; in lateral view as in Figs. 3, 4 . Phallic guide as in Fig. 5 . Phallus as in Fig. 6 . Ejaculatory apodeme as in Fig. 7 .

One male specimen has very similar terminalia. It differs slightly from holotype by the shape of the surstylus. Unfortunately the terminalia was lost and we prefer not to designate it as a paratype.

Female. One female probably belongs here. It is not being designated paratype because we are not secure of the association with the male.

Material. Holotype: male (INPA). Verbatim text of three pin labels: NICARAGUA, Granada, Volcán Mombacho, El Progreso, 700 m [white paper] / 15.ii.1998, J.M. Maes, Malaise trap [white paper] / Holotype ɗ, Elmohardyia nicaraguensis Rafael [red paper]. Terminalia placed in a microvial with glycerine and pinned along with the specimen.

Other specimen: San Joaquin #1, 31.iii.1998 (1ɗ MEL, terminalia lost); Santa Ana #3, 18.ii.1999 (1Ψ MEL).

Etymology. The specific name refers to the country Nicaragua.

Remarks. E. nicaraguensis sp. n. is near E. replicata (Hardy) in the similar pattern of abdominal pruinosity and surstyli shape. It is different by the shape of the hypandrium, notably by the extremely developed external side of the phallic guide.
