Rondonia batrachogena Bursey, Goldberg & Kraus 2014

Morphology and Anatomy:

Small nematodes, body more or less cylindrical throughout its length;
Both transverse and longitudinal striations in cuticle.
Narrow lateral alae beginning just posterior to lips and terminating near tail midpoint in both males and females.
Head bluntly rounded; terminal mouth, opening triangular surrounded by 3 lips, each lip with 2 simple, pedunculate papillae; 1 amphid on each ventrolateral lip.
Esophagus with anterior muscular portion and posterior glandular portion, terminating in a prominent valved bulb.
Nerve ring just posterior to junction of esophageal parts.
Excretory pore posterior to esophageal bulb; pore surrounded by circular striated cuticle..



Males: Gubernaculum with cylindrical body. Spicules similar, transversely striated, unequal, left spicule longer than right; distal ends pointed. Tail long bent ventrally to form a shepherdâ€™s crook, with thin terminal filament. Eight pairs of caudal papillae: 3 pairs precloacal: 5 pairs post cloacal, 3 pairs ventrolateral, 2 lateral pairs, 1 pair just posterior to cloaca, 1 pair just anterior to tail filament. Phasmids open near posterior end of lateral alae. Both males and females with cloaca.	Female: Both males and females with cloaca. In female, loaca empties into crease caused by tail withdrawal. Vulva opening into rectum; vagina short; monodelphic, Thin-shelled eggs in various stages of development in anterior portion of uterus; hatched larvae present and often filling uterus. Viviparous. Single ovary near middle of body. Phasmids open near posterior end of lateral alae. Ref: Bursey et al., 2014
