03CECD466B515D4BFF14FBD91CCB24D6.taxon	discussion	Remarks: Tegmina venations are used as diagnostic characters for the genus, and a general diagram of forewing venation of Borysthenes is provided (Fig. 7 A). However, it has been observed on some species that venations, especially the terminal furcation of each longitudinal vines, are subjected to intraspecific variations (e. g., specimen with 6 - ternimaled MP as in Fig. 1 E, and specimen with 3 - ternimaled RP as in Lyu & Webb 2023, Fig. 1 A – C). Emeljanov (1989) provided a forewing venation diagram based on Borysthenes fatalis Emeljanov from Vietnam, showing three veinlets between MP and CuA. However, only two veinlets between MP an CuA were observed on specimens studied here.	en	Lyu, Tianlang (2025): Taxonomic notes on the genus Borysthenes Stål, 1866 (Hemiptera: Fulgoromorpha: Borysthenidae), with description of six new species from China.

03CECD466B525D4EFF14F9D61F3425B7.taxon	biology_ecology	Habitat and behavior: This species was collected in Mt. Diaoluoshan, Hainan Island. It is among the few places on Hainan Island where developed rainforest remains as the dominant vegetation. At daytime, this species was observed in high density (ca. 10 ind. per m 2), dwelling on the shaded undersurface of large boulders (Fig. 6 F). They are inactive and easy to capture by hands during daytime. At night, they were found on shrubs and ferns throughout rainforest understory, alert and difficult to capture by hand.	en	Lyu, Tianlang (2025): Taxonomic notes on the genus Borysthenes Stål, 1866 (Hemiptera: Fulgoromorpha: Borysthenidae), with description of six new species from China.

03CECD466B545D4CFF14F8B41E412593.taxon	discussion	Remarks: This species is s omewhat similar to B. xuzhiae sp. nov., see remarks on the latter. The male genitalia of B. mysterius sp. nov. is also similar to that of B. fatalis Emaljanov (1989) from Vietnam. The type of B. fatalis have not been examined, but the original description and illustration of the male genitalia was comprehensive. B. mystherius sp. nov. can be distinguished from the latter by: a) lateral lobes of pygofer with sharp processes, upper slope straight (in B. fatalis, lateral lobes with irregularly blunt projections, upper slope strongly concave), b) male anal segment with two lateral margins of similar length from dorsal view, right lateroventral margin extended ventrally, much longer than the left one (in B. fatalis, right lateral margin shorter from dorsal view, right ventrolateral margin slightly extended ventrally, folded cephalic), c) aedeagus with 5 sharp processes, no flat ventral projection at the middle of periandrium (in B. fatalis, aedeagus with 4 apical sharp processes and a flat ventral projection at the middle of periandrium). B. mysterius sp. nov. is described by a single male specimen preserved in SYSBM, having unique tegmina markings and male genitalia structure, thus designated here as a separate species. Four field surveys have been conducted recently at Mt. Jianfengling, the type locality of this species, but no Borysthenes species were collected.	en	Lyu, Tianlang (2025): Taxonomic notes on the genus Borysthenes Stål, 1866 (Hemiptera: Fulgoromorpha: Borysthenidae), with description of six new species from China.

Two surveys were conducted on two consecutive days in the “ Lvshilin ” scenic area, where the karst landform and rainforest are developed. The first survey was conducted from afternoon to night. At dusk, B. delicatus were first recorded on rock surfaces and vegetation around limestone crevices. After sunset, B. delicatus can be frequently found on understory vegetation. They exhibited a rather abrupt transition from invisible to very common around the forest understory at some point during dusk.

Wings of female specimens are folded due to soak of ethanol; female body length weren’t measured. Females are about the same size as males. Habitat and Behavior: This species is so far only recorded in the mountainous area of Hainan Island. Most of the type specimens were collected at night in a hotel garden near the entrance of Wuzhishan National Reserve, where the majority of vegetation was artificially planted and specimens dispersed throughout them. One specimen was collected during the daytime using a sweep net, near Boliwan reservoir along road X 437, about 40 km from the previous location.	en	Lyu, Tianlang (2025): Taxonomic notes on the genus Borysthenes Stål, 1866 (Hemiptera: Fulgoromorpha: Borysthenidae), with description of six new species from China.
