ABSTRACT A new genus of Noterini, Prionohydrus Gómez and Miller gen. n., and three new species are described from South America: Prionohydrus matogrossensis Gómez and Miller sp. n. from Brazil and Prionohydrus marc Gómez and Miller sp. n. and Prionohydrus ubercornis Gómez and Miller sp. n. from Venezuela. The new genus was scored for characters presented in a recent phylogenetic analysis of the family, and key morphological characters are illustrated, including male and female genitalia. A parsimony analysis of these data resulted in a single, most parsimonious solution, with members of the new genus resolved as sister to Mesonoterus Sharp with moderate support. Prionohydrus is similar to Mesonoterus and can be distinguished from this and other Noterini based on a combination of the following: 1) distal attachment of protarsus to protibia; 2) posterior protibial spine present; 3) single, weakly curved, apical protibial spur present; 4) last abdominal tergum with large medial spine flanked by numerous setae; 5) posterior mesotibial spur strongly serrate; 6) anterior metatibial spur strongly serrate; 7) prosternal process narrow, rounded apically, and widest near the middle; 8) prosternum longitudinally broad and glabrous; 9) weak, angular setae along posterodistal margin of metafemur present; 10) pronotal bead moderately broad; 11) cluster of setae at apex of medial metacoxal lobe present; and 12) antenna of males expanded, from slightly incrassate to strongly incrassate.

PrionoHydrus,来自南美洲的Noterini Thomson(鞘翅目:Noteridae)新属,三个新种及其系统发育考虑



摘要 Noterini、PrionoHydrus Gómez 和 Miller gen 的新属。 n.,并且描述了来自南美洲的三个新物种:PrionoHydrus matogrossensis Gómez 和 Miller sp.。名词来自巴西和 PrionoHydrus marc Gómez 和 Miller sp。名词和 PrionoHydrus ubercornis Gómez 和 Miller sp。名词来自委内瑞拉。该新属根据最近对该科的系统发育分析中出现的特征进行了评分,并说明了关键的形态特征,包括男性和女性生殖器。对这些数据的简约分析得出了一个最简约的解决方案,新属的成员在中等支持下被确定为 Mesonoterus Sharp 的姐妹。 PrionoHydrus 与 Mesonoterus 相似,可以根据以下特征的组合与 Mesonoterus 和其他 Noterini 区分开来:1) Protarsus 远端附着于 Protibia; 2) 存在后胫骨棘; 3) 存在单个、弱弯曲、顶端的胫骨骨刺; 4) 最后腹部底板有大的内侧棘,两侧有许多刚毛; 5) 后胫骨骨刺强烈锯齿状; 6) 前胫骨骨刺强烈锯齿状; 7) 前胸骨突起狭窄,顶部圆形,靠近中部最宽; 8) 前胸板纵向宽且无毛; 9) 沿着股骨后远侧边缘存在弱的、有角的刚毛; 10) 前额珠适度宽; 11) 内侧跖基叶顶端有刚毛簇; 12)雄性的触角扩张,从轻微增大到强烈增大。
