Measurements (Thorne):
L = 0.8 mm; a = 33; b = 4.1; c = 38; V = 35
L = 0.8 mm; a = 33; b = 4.4; c = 50

Description (Thorne):
Body cylindroid, tapering rapidly to narrow lip-region.  Posteriorly ending in a slightly clavate tail with strong radial striae.  Lateral fields 2 or 3 times as wide as cuticle thickness.  Amphids almost as wide as head, their sensilla lying just posterior to base of spear extensions.  Spear 5 or 6 long.  Guiding ring not observed.  Esophagus at first slender, fusiform, tapering to a narrow tube as it passes through the nerve-ring. Basal half of esophagus enlarged by gradual expansion, glandular, with weak radial musculature, all 5 nuclei usually visible.  Cardia cylindroid, but sometimes compressed to a disk by fixation.  Intestinal cells hyaline with few scattered granules.  Prerectum length 4 or 5 times body width.  Vulva transverse.  Anterior uterine branch shorter than body diameter. Ovary reflexed halfway or more to vulva, often pressed forward by developing ova.  At flexure of ovary is a pouchlike organ visible in young females in which are several bodies which which may be syngonic spermatozoa.
 Male body similar to that of female.  Testes well-developed with great numbers of spermatozoa.  Spicula rather angular, with tiny lateral guiding pieces.  Copulatory musculature very obscure.  Supplements an adanal pair and 2 ventro-median, widely spaced.   Belondira parva is distinctive because of its small size and tail form.
Habitat. Soil about the roots of yam, Aguada and Gurabo; coffee, Limani; banana, Rio Piedras; and El Yunque Rain Forest.
