Diversity of Insects Trapped in Nepenthes at Gunung Kunyit Forest, Jambi Province, Indonesia

<b>Background and Objective:</b> <i>Nepenthes</i> is a marsupial plant that is a modification of the leaf tip and serves to trap insects. The difference in the position of the pitcher is expected to distinguish the insects that inhabit it. One of the locations <i>Nepenthes</i> was Gunung Kunyit which is included in the Kerinci Seblat National Park Area. Insects trapped in the <i>Nepenthes</i> can be studied through taxonomic studies. The objectives of this study were to determine the diversity of insects trapped in the <i>Nepenthes</i> and to know the species of <i>Nepenthes.</i> <b>Materials and Methods:</b> The research was conducted from February to May, 2022. The study used a survey method by direct observation in the field. <b>Results:</b> The insects found in the <i>Nepenthes</i> consisted of 3 orders, 7 families and 10 species. The most insects found to be <i>Crematogaster</i> sp., (82 individuals) and the least insects <i>Sceliphron</i> sp. and <i>Dasiops</i> sp. (5 individuals). At the research site, three species of <i>Nepenthes</i>, <i>N. bongso</i>, <i>N. gymnamphora</i> and <i>N. inermis</i> at an altitude of 1,768-1,993 meters above sea level (m.a.s.l.). <b>Conclusion:</b> The insect diversity index in the upper pitcher was 1.79 and for the lower pitcher position was 1.31, so it was categorized as a medium level.

Thismiasumatrana (Thismiaceae), a new species from West Sumatra, Indonesia, with discussions on the taxonomic identity of Thismiaclavigera

A new species of the mycoheterotrophic genus Thismia Griff. (Thismiaceae), Thismiasumatrana Suetsugu & Tsukaya, from West Sumatra, Indonesia, is described, based on a rehydrated herbarium specimen from National Museum of Nature and Science, Japan. Thismiasumatrana is closely related to T.clavigera (Becc.) F.Muell. but is distinguished by a much larger flower.
