Fig. 2. Phylogeny of Sclerocoelus Marshall, 1995 based on the morphological character states in Table 1. The cladogram was rooted by Paramosina Marshall, 2014, Chespiritos Marshall, 2000, and Parasclerocoelus Marshall & Dong, 2008 as outgroups. Solid circles indicate unique synapomorphies, empty circles indicate homoplasies, and crossed circles indicate reversals. Numbers above circles indicate the character number, numbers below the circles indicate multistate character states (unordered). Species names highlighted in blue indicate brachypterous species. Red asterisks (*) beside species names indicate high elevations (2800+ m a.s.l.).
