Description (ɗ). Body length 3.1 mm; wing 3.7 mm. Head wrinkled. Eyes contiguous on frons for a distance apparently slightly greater than length of frontal triangle. Frontal triangle black, subshining black in the middle, brown pruinose in dorsal view. Face gray pruinose in dorsal view. Antennae dark brown, flagellum apex acute. Thorax black, brown pruinose dorsally and gray pruinose laterally (mesopleuron and postnotum). Legs black, except apex of femora and tibiae, base of tibiae and basal tarsomeres yellow. All femora with ventral ctenidia. Tibiae without apical bristles and hind tibia without erect posterior bristles. Wing hyaline with brown pterostigma, third costal section twice as long as fourth; vein rm placed near basal one fourth of cell dm; vein M1 straight. Halter yellow to brown. Abdomen ( Fig. 33 View FIGURES 33 – 43. 33 – 37 ) black, broadest at about segment three, brown pruinose, except tergite 1 entirely gray pruinose, tergites 2–4 gray pruinose posterolaterally and tergite 5 posteriorly. Syntergosternite 8 brown pruinose, shorter than the length of tergite 5, with membranous area ventrally. Epandrium and surstyli ( Fig. 34 View FIGURES 33 – 43. 33 – 37 ) dark brown to black, except apex of surstyli rather yellow. Surstyli subsymmetrical; in dorsal view outcurved distally and in lateral view downcurved ( Figs. 34, 35 View FIGURES 33 – 43. 33 – 37 ). Phallic guide and phallus as in Fig. 36 View FIGURES 33 – 43. 33 – 37 . Phallus apparently bifid. Ejaculatory apodeme as in Fig. 37 View FIGURES 33 – 43. 33 – 37 .

Material. Holotype ɗ (INPA). Verbatim text of three pin labels: NICARAGUA, Granada, Volcán Mombacho, Santa Ana #2 [white paper] / 30.vi.1998, J.M. Maes, Malaise trap [white paper] / Holotype ɗ, Eudorylas vulcanus Rafael [red paper]. Terminalia placed in a microvial with glycerine and pinned along with the specimen.
Etymology. The specific name refers to the place where the specimens were collected, Volcán Mombacho. From Latin vulcanus (= volcano).
Remarks. D. vulcanus , sp.n. is close to D. nigripedes . It differs by conspicuous gray pruinosity on posterior margin of tergites (brown pruinose and inconspicuous in nigripedes ) and a bifid phallus (trifid in nigripedes ).
