Genus Lipotactes Brunner-Wattenwyl, 1898

NOTE. This genus was united with the former genus Mortoniellus Griffini, 1909 by Hebard (1922). Later, different authors considered Lipotactes and Mortoniellus as one genus or as two genera (see Ingrisch, 1995), but in the latter paper, Mortoniellus was diagnosed as a distinct genus for some large species having the frons quadrangular, 2

ovoid or triangular (but in reality, this structure is more or less intermediate in shape in almost all the species studied by me), the pronotum with a “transverse undulation” (but the pronotal shape is diverse in the congeners, included by Ingrisch in Mortoniellus , and possibly connected with their body size), and the male cercus with a distinct proximedial hook and a small tubercle on the base of this hook or near it ( Figs 1, 2, 4, 5, 7, 8, 11, 12, 16–19, 21, 23 ). All these characters do not allow me to dependably distinguish Mortoniellus sensu Ingrisch from some of the species included by him in Lipotactes ; moreover, Ingrisch also mentioned about this problem in the same paper.

Thus, I propose for a preliminary decision of this problem to reunite Lipotactes and Mortoniellus into one genus with nine subgenera having different structure of the male copulatory apparatus. However, L. azuriventer Karny, 1924 and L. vittifemur

Karny, 1924 (described after a nymph and a female from South Sumatra) as well as

L. longicauda Ingrisch, 1995 (described after a female from West Sumatra) are not included here in any subgenus. These species need to be restudied after the discovery of their males. Two other species, described after their males but unstudied by me,

are possibly belonging to an unknown subgenus of Lipotactes s. l.: L. laminus Shi et

Li, 2009 and L. truncatus Shi et Li, 2009 (all from South China).
