Abstract	The larval stage of Amblyomma oblongoguttatum Koch is redescribed using optical and scanning electron microscopy. Unfed larvae were obtained from a colony of A. oblongoguttatum originated from engorged females collected on domestic pigs from Monte Negro municipally (10°29’S, 63°32’W), State of Rondonia, Western Amazon, Brazil. Several characters are presented including the chaetotaxy of the idiosoma, palpi and Haller’s organ, as well as morphological features of the idiosoma, gnathosoma and legs. In addition, the porotaxy (topographical and numerical patterns of integumentary structures) were presented by using a new nomenclature recently proposed. The chaetotaxy of the larvae of A. oblongoguttatum, in general, is similar to other Neotropical Amblyomma species. Three types of integumentary structures were observed on the idiosoma: lyrifissures, small glands, and large wax glands. Topographic and numerical patterns of the integumentary structures consisted of 5 pairs of large wax glands (1 dorsal/ 4 ventral), 24 pairs of lyrifissures (11 dorsal/ 13 ventral), and 49 pairs of small glands (28 dorsal/ 21 ventral). These topographic and numerical patterns found for A. oblongoguttatum show only minor differences when compared with patterns of other Amblyomma larvae, however, a few key features can be used for identification of these species.
