Phytosciara (Prosciara) vulcanata Steffan, 1973 

( Fig. 15 A – DView FIGURE 15)

Phytosciara (Prosciara) vulcanata Steffan, 1973  [Steffan (1973a): 358, fig. 2 a – h].

Material studied: Holotype  , 10.-17.vii.1972, Hawai‘i Island, east slope Mauna Loa, 7000 ft., pitfall trap, leg. J. Jacobi (Bishop Museum 9942). Paratypes: 1 male, 15.vii.1972, Hawai‘i I., Kazumura Lava Tube near Mt. View, 400 m, leg. F. Howarth  ; 1 male, 1.xii.1968, Hawai‘i I., Kīpuka "6", 19.7 miles W of Hilo, 5250 ft., sweeping, leg. W. Gagné (1 in PWMP)  .

Further material: 1 male, 29.iv.1972, Hawai‘i I., West Maui, Haiku Cabin, Pu‘u Kukui Trail, Malaise trap, leg. J.L. Gressitt (BPBM).

Conservation status: Embedded in Euparal. Body and head separated, all details in good condition.

Comments. Steffan correctly assigned the species to the subgenus Prosciara  . It looks like a typical species of Bradysia  , only the base of the apical spines is pronounced and the claws strongly toothed, not common in the genus Bradysia  . It is further characterized by the rough flagellomeres with short curved hairs and short dense hairs in the intergonocoxal space (there is not a true lobe). The slide labelled holotype bears the number BPBM 9942 which differs from the number listed in Steffan’s original description and in his type catalogue (BPBM 9943) (Steffan 1973a; 1976).
