description: <i>Transeius maelliae</i> Kreiter n. sp. Zoobank: C6EA34F5-9601-4208-8201-B14CE6C6FC5D <b>Diagnosis</b> — <i>Transeius maelliae</i> Kreiter <b>n. sp.</b> belongs to the subfamily Amblyseiinae (absence of dorsolateral setae <i>z3</i> and <i>s6</i> and caudoventral seta <i>JV3</i>), to the tribe Amblyseiini (setae <i>j3</i>, <i>s4</i>, <i>Z4</i> and <i>Z5</i> longer than other setae, ratio <i>s4</i> / <i>Z1</i> &gt; 3.1, many teeth on the fixed cheliceral digit and macrosetae on several legs in addition of the three on leg IV), to the subtribe Amblyseiina (sternal shield as long as wide, ventrianal shield longer than wide, seta <i>J2</i> present, genital shield almost as wide as ventrianal shield, ventral shields generally smooth, macrosetae on all legs, setae <i>j5</i>, <i>J2</i>, <i>S2</i>, <i>S4</i>, <i>S5</i> and <i>Z1</i> present), to the genus <i>Transeius</i> (ratio <i>s4</i> / <i>S2</i> &lt;2.7, Setae <i>S5</i> present, spermathecal with atrium not bifurcate) (Chant and McMurtry 2007). Seta <i>z4</i> is not as long as 2/3 the distance between its base and that of seta <i>s4</i> that allows to classify this new species in the species group <i>bellottii</i> (Chant and McMurtry 2004a). The bell-shaped spermatheca keys to the species subgroup <i>bellottii</i>. <i>Transeius maelliae</i> Kreiter <b>n. sp.</b> is quite similar to the other new species described further, <i>T. mickaeli</i> Kreiter <b>n. sp.</b> with which it was at first confused early on during the identification process. <i>T. maelliae</i> <b>n. sp.</b> is different from <i>T. mickaeli</i> <b>n. sp.</b> by: having only five solenostomes instead of seven, a longer seta <i>z4</i>, almost double, the shape of the spermatheca also bell-shaped but with an undistinct atrium, longer setae <i>JV5</i>, less teeth on both digits of chelicerae and very slightly reticulated ventral shields (see table 27). In the species subgroup <i>bellottii</i>, the species closest to <i>T. maelliae</i> <b>n. sp.</b> is <i>Transeius jujae</i> El-Banhawy and Knapp. <i>T. maelliae</i> <b>n. sp.</b> resembles to <i>T. jujae</i>, having similar lengths for setae <i>j3</i>, <i>s4</i>, <i>Z4</i>, <i>Z5</i>, and <i>JV5</i>, and the dimensions of the spermatheca. The new species can be distinguished however by the longer length of setae <i>z2</i>, above all by the length of setae <i>z4</i> which is 2.5 as long as that of <i>T. jujae</i>, and by the shape of the spermatheca with an undifferentiated atrium and walls of calyx slightly converging apically in the new species opposed to a distinct atrium and walls of calyx strictly parallel in <i>T. jujae</i>. In addition, a macroseta is existing in the genu of leg I of <i>T. maelliae</i> <b>n. sp.</b> and lacking in specimens of <i>T. jujae,</i> the ventrianal shield is wider and the dorsal shied is totally smooth in that species.
