Tomicus armandii Li & Zhang , sp. n.

Figures 2, 3

Description. Males and females not readily distinguishable. Total length 4.1 mm (3.9–4.6 mm, N=10), 2.6× longer than wide. Head, thorax, elytra and legs of mature adults almost black, antenna color dark brown. Head as in T. yunnanensis , with frons shining, weakly convex, a fine median carina from middle of frons to just above epistoma. Antennal funicle with 6 segments; club ovate, divided by three sutures, with many uniformly short setae distributed between the sutures. Pronotum 0.8× longer than wide, shining; strongly constricted in anterior third; punctures densely distributed on the surface of pronotum. Elytra 1.9× longer than wide, 3× longer than pronotum, 1.3× wider than pronotum, weakly shining. Fine punctures densely and evenly spaced; punctures of interstria 2 on declivity appear biseriate, less than half the size of strial punctures. Legs: protibia with 9–11 marginal teeth, the two closest to body usually separated from the others. ( Figs. 3 )

Diagnosis. Compared with T. minor , T. pilifer , and T. puellus , Tomicus armandii has fine punctures on interstria 2 of declivity, instead of granules. Tomicus armandii has biseriate or triseriate punctures on interstria of the declivity, while T. piniperda and T. brevipilosus have only uniseriate punctures. Compared with T. destruens and T. yunnanensis , the erect elytral hairs of T. armandii on the declivity are shorter, about 0.5× as long as the distance between striae ( Fig. 2).

Geographic distribution. Known only from a single collection, Yunnan Province, China.

Type material. . Holotype and 29 paratypes from Mountain Zixishan, Chuxiong, Yunnan Province, 9 Sept. 2009, Cao Peng. GPS N 25°00.4’, E 101°40.9’, elev. 2454 m. Host: Pinus armandii . The holotype and paratypes are currently deposited in the Insect Collection of the Chinese Academy of Forestry (Beijing). We will deposit some of the paratypes in European museums.

Etymology. This species is named to reflect the only known host, Pinus armandii .
