Fig. 46

MATERIAL. Malaysia: 10 ♂, 9 ♀, Pahang State, Tioman I. not far from Mersing

City (Johor State) on Malay Peninsula, environs of Juara Vill. (eastern coast), 6–14.IV

2010, A. Gorochov, M. Berezin, E. Tkatsheva; 1 ♂, same data, but 10–18.IV 2011,

M. Berezin.

NOTE. These specimens are very similar to the descriptions of this species by

Hebard (1922) and Ingrisch (1995). Thus, this species, previously known from only

Singapore, is here indicated for a new locality situated not very far from its type locality .

68–72 – L. (P.) h. lorelindu subsp. n.; 73–76 – L. (P.) h. irisovi subsp. n. Body of male (66–

69, 73, 74) and of female (70, 71, 75, 76) from above or from side; male genitalia from above

Type species Lipotactes montanus Ingrisch, 1990 ( Thailand) .

DIAGNOSIS. Rostrum of head not lamellar, typical of this genus; male last tergite with a short posteromedian lobe having concave or almost straight posterior edge (this lobe possibly originating from basal part of epiproct more or less fused with last tergite but separated from more distal part of epiproct by strong transverse fold); male epiproct not reduced, without lateral lobules, with small (but distinct)

roundly triangular distal part directed more or less downwards; male paraproct with wide, horizontally lamellar and apically rounded projection at apex; male cercus elongately subcylindrical, with short or long apical spine directed medially, with more strong ventromedial spine directed also medially (?= proximedial hook in previous subgenera) but located almost in middle part of cercus, and with dorsomedial longitudinal keel on proximal part of cercus (?= dorsal tubercle at base of proximedial hook or near it in Lipotactes s. str. and Mortoniellus ) ( Fig. 25 ); male genitalia completely membranous.

INCLUDED SPECIES. Type species; L. silvestris Ingrisch, 1990 ( Thailand) .

COMPARISON. The new subgenus differs from all the previous subgenera in wide and horizontally lamellar projections of the male paraprocts as well as in the presence of apical spines at the male cerci; additionally it is distinguished from

Lipotactes s. str. by the presence of a posteromedian lobe on the last male tergite,

from Mortoniellus by the same character and the male genitalia completely membranous, from Prolipotactes by the possible presence of the dorsal tubercle near the proximedial hook in the male cercus, and from Dialipotactes by the latter character and the presence of a posteromedian lobe on the male last tergite as well as the absence of a pair of lateral lobules on the male epiproct.
