Distribution. Northern Panama. See Map 14. Key to Males of Species of Dybasia la. Sternal processes of anterior gonopocls short, diverging, not meeting in midline (Fig. 419) divergens lb. Sternal processes of male gonopods more or less elongate, meeting in midline (Figs. 416, 423) 2 2a. Coxae of posterior gonopods of male shorter than second segment, with single process (Fig. 424) chiriquia 2b. Coxae of posterior gonopods of male longer than second segment, witli two processes (Fig. 415) humerosa Dybasia humerosa Loomis Figures 415-418, Map 14 Dijhasia humerosa Loomis, 1964, Fieldiana, 47: 101, figs. lOA-I, $. Types. Male holotype from "Casita Alta," Finca Lerida, near Boquete, Chiriqui Province, Panama, collected IS March 1959 by H. S. Dybas, deposited in Field Museum of Natural Histor>% examined. The specific name probably refers to the shoul- ders on each segment. Diagnosis. As in the above key. Description of male holotype. Length, 10 mm, A3 = mm. Ocelli 23 on left side, 25 on right side, in subtriangular patch. Coloration typical of Cleidogona, midbody segments with raised shoulders, but dorsum not flat, shoulders about one- fourth body width, body segments beyond.
