The Neotropical species of the flower fly genus Orthonevra (Diptera: Syrphidae) are revised and 12 new species are described and illustrated: Orthonevra batman sp. nov., O. cthulhu sp. nov., O. gli sp. nov., O. gouletmasnerorum sp. nov., O. hypnotica sp. nov., O. minuosetulata sp. nov., O. nebulosa sp. nov., O. neiae sp. nov., O. roseae sp. nov., O. sternolobosa sp. nov., O. theta sp. nov., and O. thompsoni sp. nov. In addition, seven species are redescribed and illustrated: O. argentina (Brèthes, 1922), O. chilensis Thompson, 1999, O. flukei (Sedman, 1964), O. gewgaw (Hull, 1941), O. neotropica (Shannon, 1925), O. quadristriata (Shannon & Aubertin, 1933) and O. shannoni (Curran, 1926), and three Nearctic (one extending into the Neotropical region) species are diagnosed: O. bellula (Williston, 1882), O. nitida (Wiedemman, 1830) and O. nitidula (Curran, 1925) (for a total of 20 species with Neotropical distribution). Lectotypes are designated for two species, Chrysogater bellulus Williston and C. nitidus Wiedemann, and C. lugubris Jaennicke (1867) is removed from Orthonevra and left incertae sedis. A dichotomous and an interactive pictorial key to these species are also presented.
对花蝇科直脉花蝇属的新热带区物种进行了修订，描述并图示了12个新物种：蝙蝠侠直脉花蝇新种、克苏鲁直脉花蝇新种、格力直脉花蝇新种、古莱-马斯纳直脉花蝇新种、催眠直脉花蝇新种、小刚毛直脉花蝇新种、星云直脉花蝇新种、涅亚直脉花蝇新种、玫瑰直脉花蝇新种、胸骨叶直脉花蝇新种、西塔直脉花蝇新种和汤普森直脉花蝇新种。此外，重新描述并图示了7个物种：阿根廷直脉花蝇（布雷特斯，1922年）、智利直脉花蝇（汤普森，1999年）、弗卢克直脉花蝇（塞德曼，1964年）、小玩意儿直脉花蝇（赫尔，1941年）、新热带直脉花蝇（香农，1925年）、四纹直脉花蝇（香农和奥贝廷，1933年）和香农直脉花蝇（柯伦，1926年），并诊断了3个新北界（一个延伸到新热带区）物种：美丽直脉花蝇（威利斯顿，1882年）、闪亮直脉花蝇（维德曼，1830年）和微亮直脉花蝇（柯伦，1925年）（共有20个新热带区分布的物种）。为两个物种，即威利斯顿的金眼花蝇和维德曼的闪亮花蝇指定了选模标本，雅尼克（1867年）的悲哀花蝇被从直脉花蝇属中移除，仍保留其分类地位不明。还给出了这些物种的二歧式和交互式图片检索表。
