Russia, Krasnodar Krai, Yatyrgvarta Mountain, Caucasian Nature Reserve, Eastern Forestry (elev. 1750 m), host, Pinus sosnowskyi, 3. VIII. 2003, coll. Mandelshtam (Ipsacu 14, 15); St. Petersburg (Ipsacu 18, 19, 20); Zabaykalsky Krai, Chita (Ipsacu 23, 24). Male. Frons flat, slightly convex, shining, small pair often flanked with additional tubercles in the middle, above the epistoma, densely granulato-punctate with small central shining smooth unpunctured area in the middle between and just above a pair of tubercles. Suturae on antennal club slightly bisinuate, sometimes nearly straight. Elytral interstriae wide, at least twice the width of striae, flat, all uniseriately irregularly punctured the entire length, punctures slightly deeper and slightly smaller than striae. Striae deep, densely punctate, distance between the punctures smaller than puncture diameter. Elytral declivity, 1 st spine on 2 nd interstriae, 2 nd spine on 3 rd interstriae, 3 rd spine on 4 th interstriae, 2 nd and 3 rd spine without a common base, distance between the 1 st, 2 nd and 3 rd spines equal. 3 rd spine, base wide, narrowed towards the bifid apex, whole spine directed posteriad, upper part of the bifid process of the 3 rd spine shorter than lower process. Declivital disc shining, irregularly and not densely punctured. Outline of the elytral edge with continuous rounded costa from the apex to 7 th interstriae, tubercle-like process on the elytral apex bent dorsally. Females. Similar to males, except the 2 nd and 3 rd declivital spines subequal.	en	Knížek, Milos, Cognato, Anthony I. (2017): Validity of Ips chinensis Kurentzov & Kononov confirmed with DNA data.

Knížek (Ipsacu 4, 5); Qinghai Prov., Tongren, Kan Bula (36 ° 07 ' 024 '' N, 101 ° 43 ' 722 '' E; elev. 2600 m), 21. VII. 2006, coll. M. Knížek (Ipsacu 6, 7); Sichuan Prov. Jiuzhaigou, 13 – 19.

VII. 2005 (Ipsacu 11, 12); Chiang Mai Prov., VII. 2002 (Ac 7). Male. Frons deeply granulate punctate, rugose longitudinally, with a pair of closely set tubercles in the middle, positioned on the middle frontal callous-like elevation. Antennal club with bisinuate sutures, 2 nd suture strongly bisinuate. Elytral interstriae convex, equal width as striae, 2 nd to 6 th with no punctures or punctures sparse and minute except for the apex with obvious punctures, 7 th and remaining interstriae with obvious punctures. Striae deep, densely punctate, distance between the punctures smaller than puncture diameter. Elytral declivity, 1 st spine on 2 nd interstriae, 2 nd spine on 4 th interstriae, 3 rd spine on 4 th and 5 th interstriae, 2 nd and 3 rd spine with a common tumescence base, distance between the 1 st and 2 nd spine larger than between the 2 nd and 3 rd spines, 3 rd spine flat, basal width smaller than the interstriae, sides parallel (from lateral view), directed posteriad and obliquely upward, bifid, both processes of equal size, connection between the processes straight. Declivital disc shining, irregularly and not densely punctured. Outline of the elytral edge with continuous rounded costa from the apex to 7 th interstriae, the tubercle-like process on the elytral apex bent dorsally. Females. Similar to males, except the 2 nd and 3 rd declivital spine subequal. Comments. The connection of the 2 nd and 3 rd spines and their shape vary between northern and southern populations. The second elytral interstriae have sparse shallow punctures in Hebei, Qinghai and Sichuan specimens. The punctures are missing from the second elytral interstriae (discal area) among individuals from Yunnan, Laos and Thailand. The 2 nd and 3 rd declivital spines are connected by a shallow tumescence appearing separated in Hebei, Qinghai and Sichuan specimens (Fig. 2), while the 2 nd and 3 rd declivital spines are connected by a higher tumescence among individuals from Yunnan, Laos and Thailand.
