Abstract

Hypoxys Amyot & Serville, 1843 (Hemiptera: Heteroptera: Pentatomidae: Edessinae), for a long time considered a synonym or subgenus of Edessa Fabricius, 1803, was recently revised and reinstated to the generic rank. This genus comprises 17 described species divided in four species groups: H. quadridens, H. oxyacanthus, H. triangularis, and H. balteatus species group. Also, there is a large number of new species yet to be described. The H. balteatus species group is diagnosed by: pronotum with posterior stripe smoky brown to black with black punctures within, sometimes these punctures are surrounded by small dark spots; punctures of the pronotal disc smaller and paler than those of the posterior stripe; anterolateral margin of pronotum yellow; anterior half of scutellum with punctures large, sparse, and also on dark spots; connexivum uniformly green, without dark spots; thorax ventrally with two pairs of brown to black rounded spots; apex of pseudosutures with black to brown round spots. This species group included so far only H. balteatus (Walker, 1868). Here we describe and assign 15 new species to this group: H. amyoti sp. nov. (Suriname: Powakka; French Guiana), H. aspilogaster sp. nov. (Brazil: Minas Gerais, Espírito Santo and Rio de Janeiro), H. belenensis sp. nov. (Brazil: Pará), H. bergrothi sp. nov. (Venezuela: Amazonas; French Guiana: Saint-Elie), H. breddini sp. nov. (Bolivia: Santa Cruz and San Carlos), H. caquetensis sp. nov. (Colombia: Caquetá), H. favachae sp. nov. (Suriname: Sipaliwini; Brazil: Amapá and Pará), H. gaucho sp. nov. (Brazil: Rio Grande do Sul), H. hyalinofasciatus sp. nov. (Ecuador: Sucumbíos), H. immaculatus sp. nov. (Bolivia: Beni), H. nigroantennatus sp. nov. (French Guiana: Roura), H. santarensis sp. nov. (Brazil: Pará), H. servillei sp. nov. (Brazil: Mato Grosso and Goiás), H. stysi sp. nov. (Suriname: Coronie, Sipaliwini; French Guiana: Cayenne), and H. venustus sp. nov. (Bolivia: Cochabamba). Descriptions, measurements, photos of dorsal and ventral view of each species, and of external genitalia of both sexes, an identification key, and distributional maps are presented.

圆蝽属15新种记述(半翅目:异翅目:蝽科)

Hypoxys Amyot和Serville，1843（半翅目：异翅目：Pentatomicae：Edessane），长期以来被认为是Edessa Fabricius的异名或亚属，1803，最近被修订并恢复为属级。该属包括17个已描述的物种，分为四个物种组：H.quaddens、H.oxicanthus、H.triangularis和H.balteatus物种组。此外，还有大量的新物种有待描述。H.balteatus物种群的诊断方法是：前胸具有后条纹烟棕色至黑色，内部有黑色穿孔，有时这些穿孔被小黑点包围；前椎间盘的穿孔比后条纹的穿孔更小、更苍白；前胸前外侧缘黄色；盾片的前半部具穿孔大，稀疏，也在深色斑点上；连接均匀的绿色，没有深色斑点；胸部腹面有两对棕色到黑色圆形斑点；假缝合线的顶端有黑色到棕色的圆形斑点。到目前为止，这个物种群只包括巴尔提图斯（Walker，1868）。在这里，我们描述并将15个新物种分配给该组：H.amyoti sp.nov.（苏里南：波瓦克卡；法属圭亚那），H.aspilogaster sp.nov..（巴西：米纳斯吉拉斯、圣埃斯皮里托和里约热内卢），H.belenensis sp.nov.[巴西：帕拉]，H.bergrothi sp.nov.%（委内瑞拉：亚马逊；法属圭亚那：圣埃利），H.breddini sp.nov.\（玻利维亚：圣克鲁斯和圣卡洛斯），H.caquetensis sp.nov.（哥伦比亚：Caqueta）、H.favacae sp.nov..（苏里南：Sipaliwini；巴西：Amapá和Pará，H.servillei sp.nov.（巴西：马托格罗索和戈亚斯）、H.stysi sp.nov（苏里南：科罗尼、西帕利维尼；法属圭亚那：卡宴）和H.venustus sp.nov..（玻利维亚：科恰班巴）。介绍了每个物种的描述、测量、背侧和腹侧视图的照片，以及两性的外生殖器、识别钥匙和分布图。
