Cladocera (Crustacea: Branchiopoda) of Vientiane province and municipality, Laos

“…Macrothrix vietnamensis seems to be an endemic of the Oriental region. It was earlier misidentified as the Palaearctic M. laticornis (Jurine, 1820) (Silva-Briano et al, 1999). Macrothrix spinosa is a very common circumtropical taxon (Smirnov, 1976), occurring in isolated archipelagoes (Schabetsberger et al, 2009) and likely forming a group of cryptic species.…”

Importance of male and ephippial female characters for differentiating three Palaearctic species of Macrothrix Baird, 1843 (Cladocera: Anomopoda), with a redescription of Macrothrix dadayi Behning, 1941

“…Macrothrix capensis has an ephippium with a thick layer of porous chitin immediately under the external cuticle (Makrushin 1991). The M. laticornis or M. triserialis groups (Silva-Briano et al 1999, Kotov et al 2004, have ephippia with rounded projections. Their existence probably reflects the presence of air chambers between the external and internal walls.…”

“…Silva-Briano (1998) found only a single sensory seta on antenna I of his M. hirsuticornis; probably, a large additional male seta had been lost during dissection. (Silva-Briano 1998, Silva-Briano et al 1999) also do not describe the male labrum adequately, so tubercles on its apex are unknown. Yet, a complex system of hillocks on the male labral apex seems peculiar of hirsuticornis-like species (but not characteristic of hirsuticornis s.…”

“…M. hirsuticornis, spinosa, laticornis, triserialis, and others. Next, Silva-Briano et al (1999) demonstrated that M. laticornis s. lat. is a series of relatively locally distributed species, while found that populations of M. cf.…”

Freshwater Diversity of Zooplankton from Mexico: Historical Review of Some of the Main Groups

“…The only known blind cladoceran of the Americas, Spinalona anophthalmia, was described by Ciros-Pérez and Elías-Gutiérrez [118]. Other new species were described during this period [119][120][121].…”
