The new species is morphologically similar to Trimeroptes luanchuanensis Xue & Hong, 2005, based on the setae h 1 absent, coxisternal plates with short lines. The differences between two species are the following: prodorsal shield with few interrupted lines in the median part in T. longlinensis sp. nov. (versus prodorsal shield smooth in T. luanchuanensis); number of dorsal annuli and ventral annuli 40 to 42 and 97 to 102, respectively, in T. longlinensis sp. nov. (versus 38 and 66, respectively, in T. luanchuanensis), ray number of em 5 in T. longlinensis sp. nov. (versus 3 in T. luanchuanensis), number of longitudinal striae on coverflap 8 to 10 in T. longlinensis sp. nov. (versus 14 in T. luanchuanensis), length of setae d 51 – 58 μm in T. longlinensis sp. nov. (versus 35 μm in T. luanchuanensis).	en	Tan, Meng-Chao, Lv, An-Kang, Ruan, Hong-Yan, Zhao, Ping (2021): Two new Diptacus and one new Trimeroptes species (Acari: Diptilomiopidae) from China.

038287EC822E5769B9C4F9CBC2031DAF.taxon	diagnosis	Differential diagnosis. Diptacus hederiphagus Nuzzaci, 1975 and the new species are the only two Diptacus species that have been reported on plants of the family Araliaceae. The new species differs from D. hederiphagus in the prodorsal shield pattern (complete median line in D. suichangensis sp. nov. versus incomplete median line in D. hederiphagus), length of scapular setae sc (13 – 15 in D. suichangensis sp. nov. versus 2 in D. hederiphagus), and number of dorsal semiannuli and ventral semiannuli (68 – 70, 112 – 116 in D. suichangensis sp. nov. versus 55, 80 in D. hederiphagus). In addition, D. suichangensis sp. nov. appears to be morphologically close to Diptacus chizhouensis Wang, Xue & Hong, 2009 [found on Rubus corchorifolius Linn. f. (family Rosaceae) from Anhui, China]. They share similar characters such as coxisternal plates with fine dashes, empodium rays number (5), coverflap with striae, dorsal annuli smooth. However, these two species can be differentiated by the number of the dorsal annuli (68 – 70 in D. suichangensis sp. nov. versus 44 – 47 in D. chizhouensis), the number of the ventral annuli (112 – 116 in D. suichangensis sp. nov. versus 68 – 73 in D. chizhouensis), the length of the setae f (46 – 49 in D. suichangensis sp. nov. versus 28 – 31 in D. chizhouensis), the median line on prodorsal shield (complete median line in D. suichangensis sp. nov. versus incomplete median line in D. chizhouensis). The new species is also close to Diptacus elegantulum Rajput, Han, Xue & Hong, 2014 [collected from Acer elegantulum Fang & Chiu (Sapindaceae)] in prodorsal shield design (admedian lines complete, median and admedian lines joined by transverse lines, forming cells in the middle of shield), coxisternal plates I (with short lines and granules), and coverflap design (with longitudinal ridges). The two species differ in the following features: prodorsal shield with complete median line in D. suichangensis sp. nov. versus incomplete (versus broken median line in D. elegantulum); scapular tubercles ahead of the rear shield margin in D. suichangensis sp. nov (versus near rear shield margin in D. elegantulum); tarsal empodium 5 - rayed in D. suichangensis sp. nov. (versus 3 - rayed in D. elegantulum); dorsal opisthosoma with smooth annuli in D. suichangensis sp. nov. (versus microtuberculated annuli in D. elegantulum).	en	Tan, Meng-Chao, Lv, An-Kang, Ruan, Hong-Yan, Zhao, Ping (2021): Two new Diptacus and one new Trimeroptes species (Acari: Diptilomiopidae) from China.

The new species herein described was compared with about 18 Diptacus species known from plants of the family Rosaceae and the highest similarity was observed with D. shangzhous Xie, 2013. The two species have the same number of the empodial rays (5 - rayed), coxisternal plates with several short lines and distinct dashes, incomplete median line of prodorsal shield and similar scapular setae sc length and paraxial tibial setae l' length. However, D. pyracanthae sp. nov. can be differentiated by the sculpture of female genitalia coverflap (entirely smooth in D. pyracanthae sp. nov. versus basal granules and distal smooth in D. shangzhous), microtubercles on dorsal semiannuli (anterior 6 – 7 annuli with elongated and linear microtubercles, posterior 16 – 18 annuli with round microtubercles, and others smooth in D. pyracanthae sp. nov. versus all annuli with elongated and linear microtubercles in D. shangzhous), the number of dorsal annuli (48 – 51 in D. pyracanthae sp. nov. versus 57 – 61 in D. shangzhous). Diptacus pyracanthae sp. nov. also appears to be very close to Diptacus mercuriasis Song, Xue & Hong, 2007 infesting leaves of Mercurialis leiocarpa Sieb. et Zucc. (Euphorbiaceae) in Gansu Province (P. R. of China). They have similar sculpture of prodorsal shield and coxal plates I, scapular setae sc and setae h 1 length. Nevertheless, the new species is distinguishable from D. mercuriasis in having the coxal plates I merged, coxal plates II with fine granules, dorsal annuli smooth beside anterior 6 – 7 and posterior 16 – 18 annuli, empodium 5 - rayed. In D. Mercuriasis, coxal plates I separated, coxal plates II smooth, all dorsal annuli with elongated microtubercles, empodium 6 - rayed.	en	Tan, Meng-Chao, Lv, An-Kang, Ruan, Hong-Yan, Zhao, Ping (2021): Two new Diptacus and one new Trimeroptes species (Acari: Diptilomiopidae) from China.
