Dynatochela primus n. sp., n. gen. (Acarina; Laelaptidae; Iphiopsinae)

Abstract

and distinctly larger than those of dorsal shield; sternal pores short, with rounded ends; margins of shield indistinct. Genitoventral shield short, with a rounded posterior margin, and with one pair of genitoventral setae, which are short, stout, and smooth, and are located near the posterior margin of the shield. Outline of anal shield not distinct on the only available specimen; only two anal setae are visible. Endopodal and metapodal shields not present. Metasternal setae distinctly smaller than sternal setae; about equal in size with genitoventral setae. Ventral body setae of about equal length with setae of dorsal shield. Peritreme very short, about two and one half times as long as it is wide. Epistome not clear in specimen examined. Chelae relatively stout. Fixed chela with a bifid tip and a large distal tooth, as well as a distal seta; bears two proximal tufts of setae. Movable chela the smaller of the two; bears one blunt tooth. Maxillary corniculi distinct; all maxillary setae smooth. All palpal setae smooth; ventrally located coxal seta is largest on palp; tarsus bears the usual bifurcate seta of the Laelaptidae. Legs relatively short and stout. Most setae on legs small, although some ventral setae, especially on coxae and tarsi, are stout and spur-like; two conspicuous spur-like setae on femur of leg I; all setae smooth.
