摘要

Mesosmicrips sunae Lyubarsky et Perkovsky sp.nov.被描述于缅甸（克钦邦）约99 Ma的白垩纪中期琥珀中。这是克钦邦琥珀中描述的第二个Mesosmicrips物种。新种与该属的模式种和迄今所知的唯一同属种的不同之处在于：前胸略微拉长，长为宽的 1.1 倍；前胸后四分之一处没有短沟；前胸后外侧角钝；原胫上部平行，原胫长度是宽度的 5 倍；后背较长，只露出两个顶端可见的鳞片。跗骨公式（5-5-5）是始新世和白垩纪家族成员的特征。

A second species of Mesosmicrips Kirejtshuk, 2017 (Coleoptera: Smicripidae) from Kachin amber

Mesosmicrips sunae Lyubarsky et Perkovsky sp.nov. is herein described from ca. 99 Ma mid-Cretaceous amber from Myanmar (Kachin State). It is the second species of Mesosmicrips described from Kachin amber. The new species differs from the type species of the genus and the hitherto only known congener by the very slightly elongate pronotum which is 1.1 times as long as wide, the absence of the short grooves on posterior fourth of pronotum, the obtuse posterolateral angles of pronotum, the protibiae parallel-sided in distal quarter, the length of the protibia being 5 times greater than width, and the longer elytra leaving only two apical visible tergites exposed. The tarsal formula (5-5-5) is characteristic for both Eocene and Cretaceous family members.
