Leg І 31 (31–33), femur 11 (11–12), basiventral femoral seta (bv) 12 (12–13); genu 3 (3–4), antaxial genual seta (l ') 8 (7–8); tibia 7 (7–8); tarsus 8 (7–8), seta ft ' 5 (4–5), seta ft ' 17 (16–17), seta u ' 5 (4–5); tarsal empodium (em) 6 (6–7), simple, 4-rayed, tarsal solenidion (ω) 8 (7–8), knobbed. Opisthosoma: dorsally with 52 (52–55) annuli, with three ridges, with round microtubercles, ventrally with 71 (69–73) annuli, with round microtubercles on rear annular margins. Setae c2 35 (35–41) on ventral annulus 12 (10–12), 60 (57–78) apart; setae d 75 (65–75) on ventral annulus 29 (26–29), 35 (35–46) apart; setae e 23 (23–25) on ventral annulus 50 (50–52), 20 (20–21) apart, setae f 31 (31–33) on 6th ventral annulus from rear, 18 (18–20) apart.

MALE: Unknown.  
 Type material. Holotype, female (slide number NJAUAcariEriH70, marked Holotype), from Sambucus williamsii Hance (Caprifoliaceae), Harbin City, Heilongjiang Province, P. R. China, 26 July 2008, coll. Xiao-Feng Xue, Zhen Wang & Zi-Wei Song. Paratypes, 8 females and 3 males (slide number NJAUAcariEriH70), with the same data as holotype.   
 Relation to host. Vagrant on leaf surface. No damage to the host was observed.   
 Etymology. The specific designation sambucus is from the generic name of the host plant, Sambucus.   
 Differential diagnosis. This species is similar to Epitrimerus lonicerae Xue, Song & Hong, 2007b, from Lonicera sp. (Caprifoliaceae), but can be differentiated from the latter by the dorsal annuli with microtubercles (dorsal annuli smooth in E. lonicerae) and median and submedian lines present (median and submedian lines absent in E. lonicerae).
