Fig. 4. Cladogram, modified from a cladistic analysis by Pesenko (2000: fig. 1), maps phylogenetic events in the evolution of the mature larvae of the Halictidae: (1) Ancestral features: mandibular apex simple; anterior tentorial pit immediately above or laterad to anterior mandibular articulation; labiomaxillary region projecting, well divided into pre- and postmentum; cardo and stipes evident; maxillary and labial palpi projecting papillae; salivary opening transverse, with projecting lips; hypopharyngeal groove probably indicated either by apices of articulating arms of stipites or by posterior margin of premental sclerite if present; paired dorsolateral body tubercles present or absent but, if absent, then most abdominal segments divided into cephalic and caudal annulets; larvae cocoon spinners. (2) Rophitine lineage similar to ancestral ground plan except paired conical dorsolateral body tubercles, if not present in ancestor, now present on most caudal annulets of abdominal segments. Within that lineage (a) cocoon spinning ceased in one place (Conanthalictus) and larval characters associated with cocoon spinning lost and (b) articulating arm of stipes lost presumably more than once (Dufourea, Sphecodosoma, and Conanthalictus). (3) Anterior tentorial pit shifted mesad, so that lateral segment of epistomal ridge lengthened; labiomaxillary region recessed, and pre- and postmentum partly fused; cardo and stipes fading but still weakly evident; labial palpus reduced but evident as small papilla; salivary opening without lips; hypopharyngeal groove complete, consisting of narrow furrow with embedded articulating arms, which are slender and curving toward one another; paired transverse dorsolateral body tubercles, if not present in ancestor, present on caudal annulet of most abdominal segments;
