P.J. Schwendinger (MHNG, SV–03/20). <b>Paratypes:</b> 3&amp;male;, 2&amp;female;, same data as holotype (MHNG, SV–03/20). <b>VIETNAM, <i>Lam Dong Province</i></b> <b>:</b> 1&amp;male;, Mt.

Schwendinger (MHNG, SV–03/21). <b>Diagnosis.</b> Males of <i>Mallinella ampliata</i> sp. nov. can be distinguished from its congeners by the broad chitinous embolus, and by the peculiar shape of the TA (Fig. 1080). Females are recognized by the cordiform epigyne protruding posteriorly. <b>Etymology.</b> The specific epithet refers to the widened chitinous flange on the embolus. <b>Description.

RTA digitiform, rather short, lateral margins parallel in ventral view, apex sharply pointed. Cymbial fold occupying half length of cymbium. Conductor with triangular dorsal process directed retromesad. TA with transparent apico-retrolateral fold directed anteriad. Embolic base aligned in transverse direction, with triangular anterior margin; membranous area distinctly narrowed.

Epigynal plate cordiform, with circular genital orifices situated medially, posterior margin protruding over epigastric furrow. Insemination ducts cylindrical. Spermathecae Y-shaped in dorsal view, excavated medially, anterior part shorter than posterior one. <b>Natural history.</b> <i>Mallinella ampliata sp. nov.</i> inhabits pristine evergreen hill forests at high relatively altitude (1,300–1,500 m asl). <b>Distribution.</b> Known only from two localities in southern Vietnam.
