Abstract

The first fossil representative of the cleroid family Trogossitidae is described from mid-Cretaceous Burmese amber. Microtrogossita qizhihaoi Li & Cai gen. et sp. nov. is unique among Trogossitidae in the relatively widely separated procoxal and mesocoxal cavities, weakly asymmetrical antennal clubs, coarsely facetted eyes, coarse sculpture of dorsal and ventral surfaces of thorax in comparison with tiny body size, and the absence of spines along side margin of tibiae. Morphological characters of the fossil were analyzed together with representatives of 44 extant genera of Cleroidea (Peltidae, Lophocateridae, and Trogossitidae) in a matrix of 93 characters. Microtrogossita qizhihaoi was resolved as a member of Trogossitini within Trogossitidae. The tribal composition of Trogossitidae is discussed in light of our re-analysis of a previously published four-gene dataset under a site-heterogeneous model. The recently described lophocaterid Mesolophocateres pengweii Yu, Leschen & Ślipiński syn. nov. from Burmese amber is suggested to be a junior synonym of Burmacateres longicoxa Kolibáč & Peris.

白垩纪中期缅甸琥珀中一种保存完好的小型啃皮甲虫（鞘翅目：Trogossitidae）及其系统发育

在白垩纪中期的缅甸琥珀中发现了首个具代表性的长尾蛇科化石。李启志浩;;蔡(Cai gen. et sp. 11 .)等在曲尾虫科中是独一无二的，它们的前侧和中端腔间距相对较宽，触角棒不对称，眼面粗糙，与微小的体型相比，胸背和腹侧表面的雕刻粗糙，胫骨侧缘没有刺。对该化石的形态特征进行了分析，并在93个特征的矩阵中对现存的44个属的代表进行了分析，包括蛭形螨科、蛭形螨科和蛭形螨科。歧之浩微虫被分解为恙虫科恙虫纲的一员。根据我们在站点异质模型下对先前发表的四基因数据集的重新分析，讨论了tro八卦科的部落组成。最近描述的浅鳞中翅毛虫(penwei Yu, Leschen &Ślipiński来自缅甸琥珀的syn11 . 11被认为是Burmacateres longicoxa的初级同义词Kolibáč &珀里斯。

期刊介绍： The Journal of Zoological Systematics and Evolutionary Research (JZSER)is a peer-reviewed, international forum for publication of high-quality research on systematic zoology and evolutionary biology. The aim of the journal is to provoke a synthesis of results from morphology, physiology, animal geography, ecology, ethology, evolutionary genetics, population genetics, developmental biology and molecular biology. Besides empirical papers, theoretical contributions and review articles are welcome. Integrative and interdisciplinary contributions are particularly preferred. Purely taxonomic and predominantly cytogenetic manuscripts will not be accepted except in rare cases, and then only at the Editor-in-Chief''s discretion. The same is true for phylogenetic studies based solely on mitochondrial marker sequences without any additional methodological approach. To encourage scientific exchange and discussions, authors are invited to send critical comments on previously published articles. Only papers in English language are accepted.
