マシラグモ（猿蜘蛛）というのは、マシラグモ科に属するクモ類である。 マシラグモ科（Leptonetidae）は、ごく小さなクモ類であり、日本ではマシラグモ属（Leptoneta）のものが多数種生息している。体長はせいぜい数mm、楕円形の頭胸部と楕円形の腹部は白っぽく、足は細長く、ユウレイグモの小さいの、といった姿である。はっきりとした特徴は、目の配列である。眼の数は6個で、前方に2個が接してならび、その後方外側に2個がほぼ接しており、それらから離れて後ろに2個が中央に接してならぶ。まとめてみると、前方に4個がやや弧を描き、後方に2個、ということになる。この様な配列は他にはない。ただし、いくつかの眼が退化傾向にある種もある。 洞窟や森林の落ち葉の間など、湿った暗い場所に生息し、小さなシート状の網を張る。 「https://ja.wikipedia.org/w/index.php?title=マシラグモ&oldid=46977054」から取得 カテゴリ: クモ

Leptonetidae is a family of small spiders adapted to live in dark and moist places such as caves. The family is relatively primitive having diverged around the Middle Jurassic period. They were first described by Eugène Simon in 1890.
== Distinguishing characteristics == Leptonetids are small, with most falling between 2 and 5mm in total length. They are generally pale in color and feature a greenish or bluish shine due to microscopic texture on the cuticle of their exoskeleton. Those species which have retained their eyes, have 6 eyes set in a distinctive pattern, with posterior pair set back from the others. If a spider from this family looses a leg, it usually separates between the patella and tibia rather than at the coxa/trochanter joint.
