Nematode-induced demasculinisation of Dolichopus males (Diptera: Dolichopodidae) Author Kahanpää, Jere text Zootaxa 2008 1689 51 62 journal article 10.5281/zenodo.180614 549e79e9-bf81-4d14-9633-8af319a5c9dd 1175-5326 180614 Dolichopus discimanus Wahlberg, 1851 Dolichopus discimanus Wahlberg, 1851 : 301 Dolichopus mucronatus Becker, 1917 : 147 Dolichopus mucronatus is known only from Sweden ( Negrobov 1991 , Pollet 2006 ). According to the original description, it has all the typical features of a demasculinised male: very small male genitalia, a broad face and weakly developed secondary sexual characters ( Becker 1917 ). Ringdahl (1949) and Grichanov (2004) treated D. mucronatus as an aberrant form of D. discimanus Wahlberg. It is likely that this synonymy is correct.
