A new blackfly species of Simulium (Gomphostilbia) from Java, Indonesia (Diptera: Simuliidae).

Abstract

Abstract:A new blackfly species, Simulium (Gomphostilbia) parahiyangum sp. nov. is described based on the female, male, pupal and larval specimens collected from Java. This new species is very distinctive among the Gomphostilbia species in possessing prominent dorsal protuberances on abdominal segments 1-5 and a deep postgenal cleft reaching the hypostomium in the larval stage. By the number of antennal segments (11 vs. 10) the male of this species is easily distinguished from that of S. (G.) varicorne Edwards, 1927 reported from Sumatra, to which the larva and pupa of this species had been once thought to be conspecific.

A new species and new records of black flies (diptera: simuliidae) from Thailand.

“…By sharing the deep postgenal cleft and dorsal protuberances on the abdomen in the larval stage, this species is also similar to S. (G.) parahiyangum originally described from Java (Takaoka and Sigit, 1992) . However, S.…”

“…This species is readily distinguished from most of other Gomphostilbia species in the pupa by the eight short, slender filaments per side, and antennal sheath with nine well marked ridges on the outer margin, each covered with several cone-shaped tubercles, and in the larva by the prominent dorsal protuberances on the abdominal segments 1-5, several dark stout spines on the abdominal segments 6-8, and the deep postgenal cleft reaching the posterior margin of the hypostomium (Takaoka and Sigit, 1992 pointed out several characters of the Thailand specimens differing from those of the specimens from the type locality.…”

Description of the female of Simulium (Gomphostilbia) gombakense (Diptera: Simuliidae) from Thailand

“…1B) (Jitklang et al, 2008;Takaoka and Davies, 1995;Takaoka and Suzuki, 1984;Takaoka and Sigit, 1992). The color of the hair tuft of S. (G.) curtatum, which was not clearly noted in the original description (Jitklang et al, 2008), is confirmed by observing the unique paratype female specimen (preserved in alcohol) deposited at Department of Infectious Disease Control, Faculty of Medicine, Oita University.…”

Three new species of Simulium (Gomphostilbia) (Diptera: Simuliidae) from Sabah and Sarawak, Malaysia

“…were reexamined, and the result shows that the pupa is S. (G,)Parahiyangum Takaoka and Sigit, originally described from Java (Takaoka and Sigit, 1992) and later recorded from Sabah and Sarawak (Takaoka, 2001a(Takaoka, , 2008b (Fig. IE, F (Takaoka and Davies, 1995 (Takaoka and Sigit, 1992;Takaoka, 2003Takaoka, , 2008a (Fig.…”
