A new genus and species of tetradonematid nematode, Myrmeconema neotropicum n. g., n. sp., is described from larval, pupal and adult stages of Cephalotes atratus L. (Hymenoptera: Formicidae) in Peru and Panama. Diagnostic characters of the new genus include: males and females subequal in size; cuticle with minute annulations; six cephalic papillae; stylet present in all stages; stichocytes absent; trophosome degenerate; three penetration glands; gonads paired and opposite; vulva in mid-body region; single spicule; genital papillae absent; adult tails rounded; infective juveniles moult once in egg; and adults of both sexes remain in the host throughout their development. As the female nematodes mature inside the worker ants, the host gasters change colour from black to red.
在秘鲁和巴拿马,从黑头举腹蚁(膜翅目:蚁科)的幼虫、蛹和成虫阶段中发现了一种新的四盘线虫属线虫,新热带蚁线虫,新属,新种。新属的诊断特征包括:雄虫和雌虫大小相近;角质层有微小环纹;六个头部乳突;各阶段均有口针;无刺细胞;营养体退化;三个穿刺腺;性腺成对且相对;阴门位于虫体中部区域;单个交合刺;无生殖乳突;成虫尾部圆形;感染性幼虫在卵内蜕皮一次;雌雄成虫在整个发育过程中都留在宿主体内。随着雌线虫在工蚁体内成熟,宿主腹部会从黑色变为红色。
