摘要

海螺科是海螺总科中一个小而形态统一的科。本文报道了中白垩世缅甸琥珀中发现的一种罕见的helotids，以Lobatihelota lescheni Li, Liu & Cai gen. nov.， sp. 11和L. iridescent Li, Liu & Cai sp. 11为代表。Lobatihelota在家族中是独特的，具有一些Nitidulidae和Kateretidae典型的腿形态(胫骨远端加宽，跗骨1-3双裂片，跗骨4缩短)。此外，本文还提出了来自同一沉积物的Trihelota的新的诊断特征(前胸和中腔体与隆突成一对，后掌叶短，后掌叶侧与鞘翅相遇)，并利用层形态空间方法直观地显示了Erotyloidea、Nitiduloidea和Cucujoidea超科代表属的形态分化。ZooBank: urn: lsid zoobank.org:酒吧:fe0e4d6a - 8157 - 4 - e14灯头- 9240 - 7 - b87f285aea5

An unusual lineage of Helotidae in mid-Cretaceous amber from northern Myanmar (Coleoptera: Nitiduloidea)

ABSTRACT Helotidae is a small and morphologically uniform family in Nitiduloidea. In this study, we report an unusual form of helotids, represented by Lobatihelota lescheni Li, Liu & Cai gen. nov., sp. nov. and L. iridescens Li, Liu & Cai sp. nov. from mid-Cretaceous Burmese amber. Lobatihelota is unique within the family in having a leg morphology typical of some Nitidulidae and Kateretidae (tibia widened distally, tarsomeres 1–3 bilobed, tarsomere 4 shortened). Additionally, new diagnostic characters are suggested for Trihelota from the same deposit (prosternum and mesoventrite with paired carinae, metanepisterna short, metacoxae meeting elytra laterally), and the morphological divergence of representative genera of the superfamilies Erotyloidea, Nitiduloidea and Cucujoidea is visualised using a phylomorphospace approach.

期刊介绍： Invertebrate Systematics (formerly known as Invertebrate Taxonomy) is an international journal publishing original and significant contributions on the systematics, phylogeny and biogeography of all invertebrate taxa. Articles in the journal provide comprehensive treatments of clearly defined taxonomic groups, often emphasising their biodiversity patterns and/or biological aspects. The journal also includes contributions on the systematics of selected species that are of particular conservation, economic, medical or veterinary importance. Invertebrate Systematics is a vital resource globally for scientists, students, conservation biologists, environmental consultants and government policy advisors who are interested in terrestrial, freshwater and marine systems. Invertebrate Systematics is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
