Deposited in MHNG.</p> <p> <i>Etymology:</i> Adjective, ‘from Rattota’, after the type locality.</p> <p> <i>Diagnosis:</i> Males of <i>O. rattotensis</i> are readily separated from those of <i>O. patellari</i> s and <i>O. indra</i> by the absence of TA2. Separated from <i>O. complexipalpis</i>, <i>O. kanoi</i>, <i>O. kaharian</i>, and <i>O. nigrimaculatus</i> by the filiform conductor. Separated from <i>O. pethiyagodai</i> and <i>O. quinquenotatus</i> by the shape of the MA. Separated from <i>O. nigricauda</i> by the presence of a</p> <p> REVISION AND CLADISTICS OF <i>ONOMASTUS</i> 743</p> <p>well-developed, pleated MA. Females are difficult to diagnose, but may be separated by details of the internal genitalia.</p> <p> <i>Male holotype:</i> Total length: 2.8; prosoma length: 1.4, width: 1.1. Legs I: femur 1.1, patella 0.5, tibia 3.2, metatarsus 2.3, tarsus 1.3. The spiders are green in nature. They turn whitish to pale yellow in alcohol. Prosoma oval, longer than wide. Opisthosoma longer than wide, lighter in colour. Leg I yellowish brown, leg II–IV light yellow. Legs are laterally without dark markings. Eyes surrounded by dark rings. Chelicerae yellow, with seven retromarginal and three promarginal teeth. Leg formula 1432. Leg spination: metatarsus V 4-2-2; tibia D 1-0-0, V 4-2-4; patella D 1-0-0; femur D 0-2-2.
