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 .

Female unknown.

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 ).
