Abstract This is the second of three papers dealing with records and distribution data of species-level taxa of Chironomidae currently known to occur in Ireland. Information is presented on 226 species-level taxa in the subfamily Orthocladiinae. The majority of the 9,420 records cited have not been published previously. Key words: Chironomidae, Orthocladiinae, Ireland, records, distribution Introduction This is the second of three papers presenting records and distribution data of Chironomidae in Ireland. In Part 1 information was given on 4,360 records of 84 species-level taxa in the subfamilies Buchonomyiinae, Podonominae, Tanypodinae, Telmatogetoninae, Diamesinae and Prodiamesinae (Murray et al., 2013). Data is presented in this work, Part 2, on the distribution in Ireland of 226 species-level taxa in the subfamily Orthocladiinae. The majority of the 9,420 records cited have not been published previously. Background information and details of various publications, theses and reports consulted but not cited in Part 2 is given in Murray et al.
