Checklist and Zoogeographical Region Analysis of Hawkmoths (Lepidoptera:Sphingidae) in the Guokui Mountain,Heilongjiang Province

摘要

This paper conducted a systematic survey and zoogeographical region analysis of the family Sphingidae in the Guokui Mountain,Heilongjiang Province.Collections were made from May 2023 to August 2024 using the light-trap method.A total of 14 species and 11 subspecies from 18 genera and three subfamilies were recorded.One species (Ambulyx tobii) and two subspecies (Ambulyx japonica koreana and Clanis undulosa undulosa) were new records for Heilongjiang Province.The study showed that the subfamily Smerinthinae had the most species (subspecies),while the subfamily Sphinginae had the fewest.Among the world's zoogeographical region,most species (subspecies) in the Guokui Mountain belonged to the palearctic region,with eight species and seven subspecies were also found in the oriental region.This indicated a close biogeographic connection between the two regions.Among the Chinese zoogeographical regions,the northeastern territory,northern territory and northwestern territory had the most abundant species (subspecies).It was also found that the distribution pattern types of hawkmoths in the Guokui Mountain were diverse,with the 'northeastern territory-northern territory-northwestern territory' and 'northeastern territory-northern territory-northwestern territory-western plateau-southwestern territory-central territory-southeastern territory' types having the most species (subspecies).In addition,the Guokui Mountain hawkmoths were mostly distributed interregionally.The distribution patterns that contained the northeastern territory were the most numerous,followed by the northern territory.The rich diversity of the family Sphingidae in the Guokui Mountain was closely related to the unique climate,environment and vegetation types in the area.The results could help to improve the biodiversity database of Heilongjiang Province and researches on hawkmoths.
