We describe the cibarial morphology in eight Psorophora species Robineau-Desvoidy: Ps. (Grabhamia) cingulata (Fabricius), Ps. (Gra.) confinnis (Lynch Arribálzaga), Ps. (Janthinosoma) ferox (Humboldt), Ps. (Jan.) albipes (Theobald), Ps. (Jan.) cyanescens (Coquillett), Ps. (Psorophora) lineata (Humboldt), Ps. (Pso.) cilipes (Fabricius), y Ps. (Pso.) ciliata (Fabricius). The species belonging to subgenus Grabhamia Theobald are characterized by palatal papillae in central position and the presence of cibarial armature. The teeth in Ps. cingulata are equal meanwhile in Ps. confinnis the internal row is spatulate with apex denticulate. In Janthinosoma Lynch Arribálzaga we observed six palatal papillae (the fore pair with less size to others) and armature absent, instead we observe small spicules toward posterior plate: abundant in Ps. ferox, and few in Ps. albipes and Ps. cyanescens. The subgenus Psorophora presents four equal size palatal papillae, cibarial armature absent, also distinctive number of trichoid sensilla (12-17), in comparison to other two subgenera (5-10). We suggest to include those diagnostic characters in the future taxonomic and systematic studies in the genus Psorophora.
我们描述了罗宾诺 - 德沃伊迪属的八种骚蚊属物种的口器形态:环带骚蚊(Ps. (Grabhamia) cingulata (Fabricius))、近缘骚蚊(Ps. (Gra.) confinnis (Lynch Arribálzaga))、凶猛骚蚊(Ps. (Janthinosoma) ferox (Humboldt))、白足骚蚊(Ps. (Jan.) albipes (Theobald))、蓝绿骚蚊(Ps. (Jan.) cyanescens (Coquillett))、线纹骚蚊(Ps. (Psorophora) lineata (Humboldt))、刺足骚蚊(Ps. (Pso.) cilipes (Fabricius))以及缨骚蚊(Ps. (Pso.) ciliata (Fabricius))。属于格拉布哈米亚亚属(Grabhamia Theobald)的物种的特征是在中央位置有腭乳头以及存在口器结构。环带骚蚊的齿相等,而近缘骚蚊的内排呈匙形且顶端有细齿。在詹蒂诺索马亚属(Janthinosoma Lynch Arribálzaga)中,我们观察到六个腭乳头(前一对比其他的小)且无结构,相反,我们观察到朝向背板的小刺:在凶猛骚蚊中丰富,而在白足骚蚊和蓝绿骚蚊中较少。骚蚊亚属(Psorophora)有四个大小相等的腭乳头,无口器结构,与其他两个亚属相比(5 - 10个),还有独特数量的毛状感器(12 - 17个)。我们建议在未来骚蚊属的分类和系统研究中纳入这些诊断特征。
