Delta
potter wasps
Delta is a genus of Old World potter wasps in the family Vespidae, subfamily Eumeninae. The genus was established by Henri Louis Frédéric de Saussure in 1855. Species are predominantly distributed through tropical Africa and Asia, with some representation in the Palearctic region. A few species have been introduced to the Nearctic and Neotropical regions. Delta wasps construct characteristic pot-shaped mud nests and provision them with paralyzed caterpillars for their developing larvae.
Delta esuriens
Okinawa Mud Wasp
Delta esuriens is a potter wasp species distributed across tropical Asia. Females construct mud nests with pot-shaped entrance holes, provisioning cells with lepidopteran caterpillars as food for developing larvae. The species is distinguished from the similar Delta pyriforme by a yellow band on the metasomal petiole. Development from egg to adult emergence spans approximately one month, with males emerging earlier than females due to shorter development times.
Meotipa
Meotipa is a genus of comb-footed spiders (Theridiidae) first described by Eugène Simon in 1895. The genus is characterized by pronounced sexual dimorphism, with females measuring 2.5–6.0 mm and males only 1.1–1.8 mm. Females possess distinctive abdominal morphology including an upward-projecting tip, rounded knob with conspicuous black flattened spines or scales, and one or two pairs of lateral humps. The genus was synonymized with Chrysso until resurrected in 2009 and currently contains 27 recognized species.
Tambiniini
Tambiniini is a tribe of planthoppers in the family Tropiduchidae, subfamily Tropiduchinae, erected by George Kirkaldy in 1907. The tribe contains more than 60 species distributed across approximately 15 genera. Its members are found primarily in South Asia, Southeast Asia, eastern Australia, and Pacific islands. The type genus is Tambinia Stål, 1859.
Trigoniulus
Asian millipede (informal, for T. corallinus)
Trigoniulus is a genus of millipedes in the family Trigoniulidae, established by Pocock in 1894. The genus contains at least 90 described species distributed primarily across tropical and subtropical regions of Asia. Species such as Trigoniulus corallinus and T. lumbricinus have been studied for their population ecology, revealing seasonal abundance patterns correlated with rainfall and temperature. The genus serves as a host for gut-associated microbes, including bacteria isolated from decaying plant habitats.
