Dinarmus basalis (Rondani, 1877) is a solitary, synovigenic, idiobiont ectoparasitoid. This study documents, for the first time, the presence of D. basalis on larval and pupal stages of the Mexican bean weevil, Zabrotes subfasciatus (Boheman, 1833). Furthermore, it describes the immature and adult stages of this parasitoid and its life cycle as it occurs on Z. subfasciatus. We report its presence in association with the common bean plant, Phaseolus vulgaris, both under natural field conditions and in storage. Ovoid eggs, hymenopteriform larvae (including a head and 12 body segments), and a prepupal stage resembling the -obtecta" pupa are easily observable characteristics of this parasitoid species. The larva is mobile; rather than remaining in one Awe to feed, it moves about over the host's body. Information is presented on the differential consumption of the host's body by males and females. Specifically, immature stages that consume the entire body generally develop into females, whereas those fading more rapidly and leaving a portion of the body uneaten typically become males. Maximum body lengths and widths are warded for each of the developmental stages. Durations of the different stages under laboratory conditions (i.e., 25/23 plus or minus 2 deg. C temperature; 75 plus or minus 5 % relative humidity; and 12/12 h light/dark photoperiod) are as follows: four days as an egg, six days as a pa after Ira, less than 20 hours as a prepupa, 10 days as a male pupa, and 12 days as a female pupa. Life cycle durations from oviposition to adult emergence are 20 and 22 days for males and females, respectively. Protandry is evident. Beginning on the sixteenth day, marked sexual dimorphism can be seen in the pupae, a condition which persists until adults emerge. The adult male generally resembles the female, but differs in the following characteristics: pilosity of the head and thorax is more evident and dense; the antennae possess two annelli of equal size; antennal width is less in males than in females and the gaster has a large. yellowish plaque on its anterior portion. The adult female has three annelli of the same size instead of two (which is characteristic of the male) and the gaster is br
