Review of the mite genus Ololaelaps (Acari, Laelapidae) and redescription of O. formidabilis Berlese

Abstract

A species of laelapid mite,Ololaelapsformidabilis, is redescribed based on male and female adults from soil in Sumatra, Indonesia. This species is distinguished from otherOlolaelapsspecies by its metapodal platelet narrowly fused with the parapodal plate and by its hologastric shield having two inverted-V-like ridges. The genus is redescribed based on a review of the literature and examination of specimens of some species. Valid species ofOlolaelapsare listed and accompanied by notes on morphological characters to assist future revision of the genus.

Review of the mite genus Krantzolaspina Datta & Bhattacharjee (Mesostigmata, Parholaspididae) with re-description of K. angustatus comb. nov. (Ishikawa) from Indonesia

“…Krantzolaspina is a well-defined genus by the unique combination of characters stated above (see diagnosis of the genus). However, a number of characters are also present in other dermanyssine families, for example, well-developed arthrodial brush(es) is/are also present in macrochelid mites, a sternometasternal shield bearing st1-st4 is shared with species of Pachylaelapidae (Mašán and Halliday 2014) and Ologamasidae (Castilho et al 2016) and the fusion of genital + ventral + anal shields forming a genitiventrianal shield is shared with two genera of Laelapidae (Ololaelaps and Oloopticus) (Beaulieu et al 2019).…”

“…Although the genitiventrianal shield is a diagnostic character for Krantzolaspina, it is not an exclusive character as it also occurs in other genera of Parholaspididae, such as Holaspulus, some species of Holaspina and Proparholaspulus, as well as in other families, such as Leptolaelapidae genus Indutolaelaps Karg, 1997. In addition, this feature occurs in some species of Laelapidae (see above), but in those species, the genitiventrianal shield is hyper-developed posteriorly and occupies most of the opisthogaster and is often named the hologastric shield (Beaulieu et al 2019). ,6,13,12,12,not counted ?,?,10,11,11,?…”
