平须舞虻属Platypalpus Macquart是舞虻科中最大的属之一,已知550余种分布世界各地.四川以前已知8种.本文记述四川平须舞虻属3新种:短芒平须舞虻Platypalpus breviarista sp.nov.,微距平须舞虻Platypalpus minor sp.nov.和亚丁平须舞虻Platypalpus yadinganus sp.nov,均属于长角平须舞虻种团Platypalpus longicornis species group,并编制了四川平须舞虻属分种检索表.“,”Platypalpus Macquart is one of the largest genera in the family Empididae with over 550 known species distributed worldwide.Eight species were known to occur in Sichuan.Here three new species belonging to the Platypalpus longicornis species group are described from Sichuan:Platypalpus breviarista sp.nov.,Platypalpus minor sp.nov.,and Platypalpus yadinganus sp.nov.A key to the species of Platypalpus from Sichuan is presented.

Single-cell RNA sequencing (scRNA-seq) is generally used for profiling transcriptome of individual cells.The droplet-based 10X Genomics Chromium (10X) approach and the plate-based Smart-seq2 full-length method are two frequently used scRNA-seq platforms,y
Successful pregnancy in placental mammals substantially depends on the establishment of maternal immune tolerance to the semi-allogenic fetus.Disorders in this process are tightly asso-ciated with adverse pregnancy outcomes including recurrent miscarriage
The rapid advancement of single-cell technologies has shed new light on the complex mechanisms of cellular heterogeneity.However,compared to bulk RNA sequencing (RNA-seq),single-cell RNA-seq (scRNA-seq) suffers from higher noise and lower coverage,which b
One of the major challenges in single-cell data analysis is the determination of cellular developmental trajectories using single-cell data.Although substantial studies have been conducted in recent years,more effective methods are still strongly needed t
Accurate identification of cell types from single-cell RNA sequencing (scRNA-seq) data plays a critical role in a variety of scRNA-seq analysis studies.This task corresponds to solving an unsupervised clustering problem,in which the similarity measurement
Annotating cell types is a critical step in single-cell RNA sequencing (scRNA-seq) data analysis.Some supervised or semi-supervised classification methods have recently emerged to enable automated cell type identification.However,comprehensive evaluations
In gene expression profiling studies,including single-cell RNA sequencing (scRNA-seq)analyses,the identification and characterization of co-expressed genes provides critical information on cell identity and function.Gene co-expression clustering in scRNA-
