Description of male terminalia
.
8th sternum with single large transversal sclerite closely placed to hypandrium (
Fig. 27
AC). Clunium (
Fig. 27A
) with well developed lateral arm, its dorsal to ventro-distal region covered by denticles, apically with dorso-anteriorly directed needle-like process. Epiproct (
Fig. 27
AB) with conical process medially; epiproct lobe weakly developed, not strongly expanded dorsally and anteriorly. Paraproct (
Fig. 27A
) with weakly developed distal lobe and with long and straight distal process directed posteriorly. Hypandrium (
Fig. 27C
) asymmetrical, with broad membranous region lateral and distal to median tongue; median tongue well developed but unmovable, its ventral surface covered by wrinkles; left process weakly projecting, serrated internally; right process keel-like, densely covered by denticles ventrally. Phallosome (
Fig. 27D
) broad on posterior margin with shallow concavity in middle, broadened laterally, narrowing to somewhat truncated anterior end, without anterior process.
Remarks
.
The species was originally described from
Sumatra
,
Indonesia
based only on female specimens and is here recorded from Peninsula
Malaysia
for the first time. The male of
T. kerinciense
is also described here for the first time. Female genitalia (
Fig. 28
) match very well with the original description of this species, especially in the characteristic body part of the subgenital plate. Judging from the male hypandrium structure, especially the unmovable median tongue (
Fig. 27C
), its placement within the
majus
group is unquestionable. The hypandrial median tongue is well developed and the ventral valve of gonapophyses is long, both characters are widely observed in other species group and thus are plesiomorphic conditions within the
majus
group.
