Aleocharine rove beetles (Coleoptera, Staphylinidae) associated with Leptogenys Roger, 1861 (Hymenoptera, Formicidae) I. Review of three genera associated with L. distinguenda (Emery, 1887) and L. mutabilis (Smith, 1861) Author Maruyama, Munetoshi Author von Beeren, Christoph Author Hashim, Rosli text ZooKeys 2010 59 47 60 http://dx.doi.org/10.3897/zookeys.59.510 journal article http://dx.doi.org/10.3897/zookeys.59.510 1313-2970-59-47 Maschwitzia dilatata (Pace, 2005) comb. n. Wroughtonilla dilatata Pace 2005 : 147 (original description). Type locality. Umran, East Khasi Hills, Meghalaya, India. Distribution. Meghalaya, India. Symbiotic host. Unknown. Diagnosis . This species is closely similar to Maschwitzia ulrichi in general appearance, but is distinguished from it by the pronotum being wider around the posterior margin and by the different shape of aedeagus, especially the apical part of the median lobe being less widened apically and largely excavated paramerally. Comments. Only the holotype has been known. The original description by Pace (2005) agrees well with the characteristics of the other congeners and he noted that this species is allied to Maschwitzia derougemonti . The symbiotic host is probably Leptogenys distinguenda or a related species.
