Popis: A new genus Mumulaelaps (Mesostigmata: Laelapidae: Hypoaspidini) is proposed to hold large, pale, agile, gregarious mites associated with the larvae of the endemic xylophagous sand scarab Pericoptus. Mumulaelaps ammochostos sp. n. is described and illustrated as its type species from P. truncatus (Fabricius) from Southshore, Christchurch, New Zealand. The new genus bears a novel mix of characters shared with Hypoaspis G. Canestrini, 1884 and Coleolaelaps Berlese, 1914 but differs from both by having, in both sexes, stout terminal spines al1 and pl1 on legs II–IV and bearing long or macrosetae of the dorsal series on femora and genua of legs II–IV. Both sexes have leg IV longest and leg II shortest with III never longer than I. The posterior edge of the sternal shield is deeply concave; the post anal seta is longer than the paranals; the hypostomal seta h3 clearly longer than h1 or h2. Stable isotopic (13C/12C; 15N/14N) analysis showed that the new species is not parasitic, but its trophic associa...
