A new species of Numbakullidae Gutu & Heard, 2002 (Tanaidacea, Peracarida, Crustacea) from the Great Barrier Reef, Australia Author Stepien, Anna text ZooKeys 2013 337 35 47 http://dx.doi.org/10.3897/zookeys.337.5903 journal article http://dx.doi.org/10.3897/zookeys.337.5903 1313-2970-337-35 Family Numbakullidae Gutu & Heard, 2002 Remarks. Gutu and Heard (2002) mentioned some morphological similarities between Numbakullidae and two other families: Kalliapseudidae Lang, 1956 and Metapseudidae Lang, 1970. The presence of filtering setae suggests a relationship to Kalliapseudidae . Gutu and Heard (2002) also listed number of characters between the two families, which imply that present of setae is a parallelism. Numbakullidae resembles the Metapseudidae in the appearance of pereopods 2-5 (elongated propodus and well-developed dactylus). Gutu (2006) later suggested that Numbakulla is most closely similar to three genera from subfamily Chondropodinae Gutu , 2008 ( Metapseudidae ): Calozodion Gardiner, 1973, Zaraza Gutu , 2006c and Chondropodus Gutu , 2006a based on configuration of terminal lobe of labium. Despite this similarities there are many characters which distinguish the Chondropodinae from the Numbakullidae : short pleotelson, usually with lateral incision, spines on antennule, labium with lateral spines, pereopod 1 digging type, with row of spines and plumose setae on basis, and propodus longer than carpus. At this point, therefore the relationships of the Numbakullidae remained unclear. Undoubtedly Numbakulla represents a separate family. According to a phylogenetic analysis based on morphological characters, the Numbakullidae is not closely related to either the Kalliapseudidae nor the Metapseudidae (personal observations, study in progress).
