The genus Eokingdonella was established by Yin in 1984, with E. gentiana (Uvarov, 1939) as the type species. Ten species have been described in this genus. A new species, E. maoi sp. nov., is described here from Yunnan Province of China, representing a new provincial record for the genus. The new species is similar to E. burrusitibia Zheng, Dong & Xu, 2013, but differs from the latter by the following characters: 1) epiproct 5.4 times as long as furcula; 2) anteromedian margin of pronotum depressed; 3) 1st transverse sulcus on pronotum not cutting median carina; 4) epiproct with median longitudinal groove between base and middle; 5) male epiproct with denticles in median.

The reproductive behavior of the oak bug Urostylis annulicornis Scott, 1874 was studied for the first time. This species lives in the crown of tall Quercus mongolica Fisch. ex Ledeb. trees making it difficult to access for study and observation. Our study aimed to elucidate the timing of mating and oviposition of U. annulicornis and the effect of temperature variations on the lifespan of adults in natural conditions. Nymphs grown from eggs that had overwintered on rhytidome fragments were placed in stationary netting cages installed on oak saplings, where the bugs were kept until adulthood. The behavior of the control pairs was monitored for 15 hours a day (from 06:00 to 21:00). The duration of an uninterrupted tandem during copulation was confirmed by additional observations at night. To facilitate egg-laying, artificial shelters were created from pieces of oak bark stacked together, attached to the stem of the plant, and placed inside cages. The number of eggs laid by the female was counted and photographed. The process of oviposition by a female on the oak tree bark in natural conditions was recorded and documented for the first time. This study of the biology of U. annulicornis, from oviposition through the sequence of postembryonic development, documenting all stages of metamorphosis, was carried out on a single plant. A summer reproductive diapause was observed in the seasonal cycle of the species. The timing of mating in U. annulicornis was shifted to autumn, the laying of overwintering eggs occurred in October, as night temperatures decreased. Males were observed performing postcopulatory mate-guarding. The effect of night cold spells on the lifespan of bugs was recorded: natural mortality of adults occurred when the night temperatures dropped below zero.

**Three new species of Sacculiphora Liu (Diptera: Phoridae) from Peninsular Malaysia, with a key to the species**

The genus Sacculiphora Liu, 2021, was first described in China with the type species Sacculiphora cultrata Liu, 2021. As part of an ongoing study on the diversity of scuttle flies in Peninsular Malaysia, several specimens from the genus Sacculiphora Liu were collected from several selected locations in the states of Johor, Kedah, Melaka and Selangor. In this paper, three new species of Sacculiphora i.e., Sacculiphora jeramensis sp. nov., Sacculiphora kwailanae sp. nov. and Sacculiphora tibionotata sp. nov. are described from Peninsular Malaysia. Current findings expand the knowledge of the morphology and occurrence of the genus Sacculiphora Liu from Peninsular Malaysia.
