蝇克跳小蜂属 1 中国新记录种(膜翅目:跳小蜂科)
A new record species of Exoristobia from China(Hymenoptera:Encyrtidae)
摘要
Abstract
[Objective]This study aimed to further enrich the biodiversity of Tianjin and China,and lay a foundation for the phylogenetic study of Encyrtidae species.[Method]The collection of Encyrtidae wasps was carried out in the east campus of Tianjin Agricultural University;the specimens were collected using a Malaise trap and stored in collection bottles containing absolute ethanol.After bringing the collected insect specimens back to the laboratory,the Encyrtidae wasps were sorted out according to their morphological characteristics under a stereomicroscope;the target wasps were dissected,and after becoming transparent in 5%(volume fraction)NaOH,the dissected head,thorax,gaster,antenna,fore wing,hind wing,fore leg,mid leg,and hind leg were successively mounted in Arabian gum on slides.Each characteristic part was photographed and measured under a stereomicroscope with a graduated eyepiece.Finally,the wasps were classified and identified according to their morphological characteristics.[Result]This study found a newly recorded species of the genus Exoristobia in China.The length of the females varies from 1.10-1.42 mm,body was generally dark brown,wings hyaline,basal and distal of fore coxa yellowish brown,mid femora also yellowish brown,mid coxa brown,all tarsi yellowish brown,head 0.83×as high as wide in frontal view,frontovertex 0.37×head width in dorsal view,with distinct piliferous punctures,antenna scape 4×as long as broad and broadest in the middle,all funicle segments broader than long,clava three-segmented,as long as all funicular segments combined,apex distinct obliquely truncate,mandible with three teeth,the rear tooth round and blunt,thorax densely covered with setae,mesoscutum with fine,scale-like sculpture,scutellum with reticulate sculpture,fore wing 2×as long as wide,linea calva open posteriorly,uninterrupted,length of mid tibial spur one-third of the mid tibia and slightly shorter than the corresponding basitarsus,abdomen heart-shaped,with the ovipositor slightly extended.The photos of female adults and the key to known Chinese species of Exoristobia were also provided.[Conclusion]The appraisal confirmed that the specimen examined,Exoristobia dipterae(Risbec,1951),was a newly recorded species in China.关键词
