Holcosus septemlineatus Group

Diagnosis.— Species of the Holcosus septemlineatus Group normally have six longitudinal rows of ventrals at midbody, reducing to two large plates in front of the preanals. A fourth supraocular is normally absent, and the first supraocular is fractured into three or more keeled scales (similar fracturing only occurs in Callopistes ), leaving 2/2 discrete supraoculars. The frontal, frontoparietals, parietals, and occipitals are all heavily fragmented into keeled scales. Keels of the frontoparietal region form a distinct keyhole shaped depression. Anterior and posterior gulars are similar in size and an intertympanic crease is absent. Dorsals are keeled and covered in aligned macroridges. The hemipenis has 5–7 discontinuous distal laminae.

Content.— Holcosus anomalus , Holcosus bridgesii , and Holcosus septemlineatus .

Distribution.— The three species of the Holcosus septemlineatus Group occur in the lowlands and piedmont of western Colombia and Ecuador.
