本文描述采自贵州地区的蝇科、棘蝇属下的三列棘蝇种团Phaonia triseriata-group二新种:肋棘蝇,新种P.crata sp.nov.和薄叶棘蝇,新种P.tenuilobatus sp.nov.。肋棘蝇,新种类似中国浙江省、缅甸等地分布的三列棘蝇P.triseriata Emden,1965,但新种具备下列不同于后者的特征:眼具淡色稀疏短纤毛,额较宽,约为两后单眼外缘间距之半;下眶鬃7;触角黑红;中鬃0+2;m1+2脉直,与r4+5脉向端部去渐次增宽;腋瓣黄褐色;中股后腹鬃列不发达,基半内具2个直立的刺状腹鬃;后胫前腹鬃2,前背鬃1;腹背后面观无条或斑。雄尾器:后面观:肛尾叶端缘的凹入很浅;侧面观:肛尾叶端部可见角形突出的内突;侧尾叶后缘平直,前缘近中部具角形凸起。另外,薄叶棘蝇,新种与肋棘蝇,新种近缘。但前者具备下列不同于后者的特征:下眶鬃5,触角鞭节约为梗节长的2倍,亦约为自身宽的2倍,颊高约为眼高的0.2倍,上倾口缘鬃2列;中鬃0+1;中、后股端部背面褐色,中股无腹鬃。雄尾器:后面观:侧尾叶内缘具2个凸起;侧面观:肛尾叶的内突发达;侧尾叶后缘中部具角形凸起,前缘虽略微波曲,但平滑,无凸起;第5腹板腹面观呈桶状,而非鼓形。新种的模式标本保存于安顺市疾病预防控制中心魏濂艨高技能人才创新工作室。
This article describes two new species of Phaonia triseriata-group from the Muscidae and three species of the genus Drosophila in Guizhou Province: the rib flies, the new species P.crata sp.nov. P.tenuilobatus sp.nov .. The new species is similar to P.triseriata Emden, 1965 in China, Zhejiang Province and Myanmar. However, the new species has the following features different from the latter: light, About 2 weeks after the outer edge of the monocular distance; the lower orbital 7; antennae black and red; midrib 0 +2; m1 +2 pulse straight, and r4 +5 pulse to the end to gradually widened; axillary flap brown; In the lower anterior abdominal mane is not developed, with two semi-inner thorn-shaped abdominal bristles; posterior tibia anterior bristles 2, before the back bristles; Male tail end: back view: the end of the anal caudate lobe is very shallow concave; side view: the end of the anal caudate lobe prominent angular protrusion; lateral tail caudal straight, the leading edge of the central bulge. In addition, thin leaf-leaf flies, new species and rib flies, new species near. But the former has the following characteristics different from the latter: the lower orbital bristles 5, tentacles whip about 2 times the length of the stalk, also about 2 times its own width, cheek height of about 0.2 times the eye height, Mane 2; medium bristle 0 + 1; in the back of the back of the back of the brown, medium without abdominal bristles. Lateral view: Lateral caudate lobe with 2 bulges; Lateral view: internal caudate lobe prominence; Lateral caudate lobe angular bulge, the leading edge although slightly curved, but smooth , No bulge; the fifth web ventral view barrel, rather than drum. The new species of specimens preserved in Anshun City Center for Disease Control Wei 濂 艨 highly skilled personnel innovation studio.
