摘要

一个新属,Skolomystax n.gen.被描述为包括以前被分配到中央目(Baetidae)的澳大利亚五月蝇。根据线粒体细胞色素氧化酶I和形态学的综合分类分析,将12个物种归入这个新属,包括两个新组合,S.elongatus(Suter,1986)n.comb。和S.collendus(Harker,1957)n.comb。,以及在若虫期描述的十个新物种:短吻S.brevis n.sp.、chionotos n.sp..、dyarrbi n.sp.,吉普斯兰S.gippslandicus n.sp..、goorudensis n.sp.hawkingi n.sp.leichhardti n.sp.paschei n.sp.、塔斯曼S.tasmaniensis n.sp.和寻常S.vulgaris n.sp.。仅从Harker(1957)的原始描述中已知的物种被分配为collendus n.comb。;类型材料丢失,因此没有进行详细处理,其有效性仍不确定。还包括伸长S.elongatus、鹰脊S.hawkingi n.sp.和莱赫哈迪S.leichhardti n.sp.的成虫。Skolomystax与Apobaetis、Callibaetis、Callibaetoides和Waltzoyphius密切相关,但与它们的不同之处在于,上唇有一个宽缺口,有一对基部小齿,上颌骨须有3段,有后翅垫,单鳃无褶皱。给出了除collendus以外的所有Skolomystax物种若虫的钥匙。

Skolomystax, a new genus for the Australian species formerly included in Centroptilum Eaton (Ephemeroptera: Baetidae)
A new genus, Skolomystax n. gen. is described to include the Australian mayflies previously assigned to the genus Centroptilum (Baetidae). Based on an integrated taxonomic analysis of mitochondrial cytochrome oxidase I and morphology, 12 species are assigned to this new genus, comprising two new combinations, S. elongatus (Suter, 1986) n. comb. and S. collendus (Harker, 1957) n. comb., and ten new species described in the nymphal stage: S. brevis n. sp., S. chionotos n. sp., S. dyarrbi n. sp., S. gippslandicus n. sp., S. goorudensis n. sp., S. hawkingi n. sp., S. leichhardti n. sp., S. paschei n. sp., S. tasmaniensis n. sp., and S. vulgaris n. sp. A species known only from the original description by Harker (1957) is assigned as S. collendus n. comb.; the type material is lost, so it is not treated in detail and its validity remains uncertain. Adults of S. elongatus, S. hawkingi n. sp. and S. leichhardti n. sp. are also included. Skolomystax is closely related to Apobaetis, Callibaetis, Callibaetoides and Waltzoyphius, but differs from them in the combination of a wide notch in the labrum with a basal pair of denticles, 3-segmented maxillary palps, hind wing pads present, and single gills without folds. A key to the nymphs of all species of Skolomystax, except S. collendus, is given.
