On the Position of the Genus Thaicungella Guţu & Angsupanich in the Apseudomorph Systematics (Crustacea: Tanaidacea)
2012
Guţu, Modest
The reclassification of the genus Thaicungella Guţu & Angsupanich, 2004 of the family Parapseudidae in family Kalliapseudidae, made by Araujo-Silva & Larsen (2010), is commented. Although it is based on phylogenetic methods, the two authors' conclusion is considered unconvincing. In this respect, it is underlined that in their analysis, no other species of the tribe Pakistanapseudini (where the genus Thaicungella was classified) are included, nor the common features, characteristic to the mentioned tribe. Under these circumstances the arguments which could establish the relationship "degree" between the genus Thaicungella and the other species of the tribe were eliminated. Practically, the main characteristic on which the two authors' conclusion was based was reduced to the presence of dactylar setae on pereopod II (setae which are absent in the other species of the tribe, but present in kalliapseudids), ignoring the numerous differences between the tribe Pakistanapseudini and, implicitly, the genus Thaicungella, and the species classified in family Kalliapseudidae.Also, the mention made by Araujo-Silva & Larsen (op. cit.), by which some affirmations were assigned to the author of present paper (Guţu, 2006) regarding the dactylar setae of the pereopod II in the species Acutihumerus cavooreni is refuted.
