| 摘要 | Isometopinae, commonly known as jumping tree bugs, represent the most basal lineage within the Miridae family, distinguished by a unique pair of ocelli positioned between their eyes. These diminutive insects, approximately 2-7 mm in length (mostly 2-3 mm in average), live exclusively on tree trunks and branches, frequently concealed within bark fissures or beneath the bark, feeding on minuscule arthropods or lichens. In Taiwan, they are predominantly associated with the trunks of ash, banyan, and tung trees. Globally, there are 289 Isometopinae species, with 80% endemic to the Old World, including 114 species across the Palearctic and Indo-Malayan regions. These species are thermophilic, inhabiting tropical to warm temperate climates.
Taiwan boasts a remarkable diversity of Isometopinae, with approximately 20 species, including 5 yet to be determined, a count that surpasses the diversity in adjacent regions in relation to its area. Re-examination of type specimens at the National Museum of Natural Science revealed instances where only a single sex had been documented for some species. Collaborative efforts with citizen scientists have led to life history imaging, uncovering that what were once thought to be distinct species are actually sexual dimorphisms within the same species. This has prompted a reassessment, where at least 2 biological species have previously been described as 4 seperate species.
Despite their tiny size, the frequent capture of Isometopinae in Malaise traps suggests notable mobility, providing insights into the association between habitat hosts and population distribution. Future taxonomic work on Isometopinae will necessitate the use of gender-neutral diagnostic characters, molecular identification, and life history studies to overcome current taxonomy challenges, thus enhancing our understanding of these cryptic creatures. |
