Prochyliza xanthostoma

biology_ecology

Biology. The species breeds on carcasses (e. g. Bonduriansky & Brooks 1999; Tabor et al. 2005). Prochyliza xanthostoma has been used as a model organism for research on several topics like larval behaviour (Bonduriansky 2002), adult fitness (Bonduriansky et al. 2005) or sexual selection (e. g. Bonduriansky & Rowe 2005; Bonduriansky 2006).

diagnosis

Diagnosis. This is the most distinctive species of genus Prochyliza. The unusually elongated pedicel in both sexes (although much more elongated in males) (Fig. 4 A, B) is an unmistakable diagnostic character for this species.

discussion

Remarks. As mentioned, P. xanthostoma was the only species included in the originally monotypic genus Prochyliza. Consequently, the original description of this genus referred to the distinctive characters of this species (Walker 1849). With the subsequent combination of other species under this genus made by McAlpine (1977), his redescription of the genus Prochyliza should be followed, as presented in the current paper.

distribution

Distribution. Nearctic; originally recorded from Northeastern Canada (Walker 1849), it is widely distributed throughout North America (McAlpine 1977).
