The genus Lechriodus is comprised of four species, with Lechriodus aganoposis being the most recently described species (Zweifel 1972). L. aganoposis is not sympatric with any of its congeners. Nine miles separate the closest localities for aganoposis at Karimui and melanopyga at Soliabeda (Zweifel 1972). Head is broader than the body (width 45% SVL); snout is sloping when viewed laterally and pointed when viewed dorsally; loreal region is concave and oblique; canthus sharp; nostrils closer to tip of snout; top of head is concave anterior to mid-ocular line. Eyes large, 11% of SVL; Tympanum is slightly smoother than surrounding skin with a diameter of 78% diameter of eye.
Relative finger lengths: 3>2>1>4; fingers are large, rounded inner metacarpal tubercle and lesser middle and outer tubercles; finger tips rounded but with no dilation or groove present. Relative toe lengths: 4>3>5>2>1; inner metatarsal tubercle three times as long as wide. Hind limbs are long with a tibial length 54% of SVL. There are many warts present on the sole. Toes have basal webbing which extends to the proximal subarticular tubercle and lateral fringes. Dorsal surfaces of the body and the limbs have a generally dispersed soft tiny warts. There is a U-shaped fold in the interorbital region with apex posteriorly faced. There are three pairs of longitudinal folds, with the most prominent from the eyelids, converging slightly in the scapular region, passing almost to end of body with slight interruptions posteriorly and the rest parallel adjacent to these. Ventral surfaces are smooth.
Coloration is that of a light tan to dark brown dorsal color. A dark brown streak is present from tip of snout through canthus and orbit and staying within the border of the tympanic membrane. A small dark blotch is present below the eye. Limbs with narrow crossbars. A triangular brown patch is present with the apex on the cloaca.
