LUNDQVIST, L. Taxonomic revision of the genus Dinogamasus Kramer (Acari Mesostigmata: Laelapidae). 1999. 109 pp. SEK 160.

The genus Dinogamasus (Kramer, 1898) is taxonomically revised and phylogenetically analysed. There are altogether 37 valid names assigned to the genus prior to this investigation.


Eight species are described as new to science: Dinogamasus albulus n.sp., D. assimiensis n.sp., D. kordofaniensis n.sp., D. levequae n.sp., D. minor n.sp., D. occidentalis n.sp., D. tonkinensis n.sp., and D. tortivus n.sp. All known type material have been investigated, except for the 4 Berlese species [Greenia hirtissima 1910 (?= Dinogamasus inflatus LeVeque 1930?), G. jacobsoni 1910 (= D. longipes LeVeque, 1931), Dolaea affinis 1918 (= Dinogamasus cockerelli LeVeque, 1930; D. northolmensis Loots, 1980) and D. villosior 1918]. Greenia sjoestedti Trägårdh, 1904 and Dolaea schoutedeni Oudemans, 1929 are both considered to be junior synonyms of D. crassipes Kramer, 1898.


Lectotypes are designated for the following species: D. amaniensis (Vitzthum, 1919), D. braunsi (Vitzthum, 1914), D. brevihirtus LeVeque, 1930, D. crassipes Kramer, 1898, D. inflatus LeVeque, 1930, D. kerrianus LeVeque, 1931, D. maxima (Vitzthum, 1919), D. oudemansi LeVeque, 1930, Dolaea vitzthumi Oudemans, 1926, Dinogamasus philippinensis LeVeque, 1930, D. piperi LeVeque, 1930, Dolaea schoutedeni Oudemans, 1929, Greenia sjoestedti Trägårdh, 1904, Dinogamasus sternisetosa (Vitzthum, 1930).


The genus now includes 36 species (or 37 if D. inflatus LeVeque turns out to be a separate species from Greenia hirtissima Berlese). Based on a phylogenetic analysis, it is discussed whether the genus originated in the far east Asia and that species have invaded Africa on at least two occasions. The phylogenetic analysis is compared to that of the Large Carpenter Bees and, with a few interesting divergences, an overall correspondence between the two systems is found.
