Triepeolus rhododontus Cockerell 1921

Triepeolus rhododontus Cockerell, 1921 Figs 9D, 12K, 15D, 26 Triepeolus rhododontus Cockerell, 1921: 5 (♂). Epeolus lectiformis Cockerell, 1925a: 623 (♀), syn. nov. Triepeolus lusor Cockerell, 1925a: 625 (♂), syn. nov. Triepeolus junctus Mitchell, 1962: 471 (♀, ♂), syn. nov. Triepeolus lectiformis – Brumley 1965: 73. Proposed common name Red-spined triepeolus. Diagnosis The following morphological features in combination tell T. rhododontus apart from all other Triepeolus in the simplex species group: the mesopleura laterally do not have erect/suberect, simple setae or have only sparse, short (<¼ MOD), erect/suberect, simple setae in addition to the usual appressed, branched setae (Figs 9D, 26A, C); the trochanters are normal (i.e., not tuberculate) (Fig. 9D); the dorsum of the mesosoma and metasoma have bands of pale-yellow tomentum (Figs 15D, 26); and the T1 discal patch is somewhat narrowed and/or curved posterolaterally and thus allantoid with an inverted U- or horseshoe-shaped anteromedial projection (Figs 15D, 26A–C). Triepeolus rhododontus most closely resembles T. obliteratus and T. oblongimacula sp. nov., but in the latter two species the axillae never (as opposed to commonly; Fig. 26C) have reddish tips, in T. obliteratus the dorsum of the mesosoma and metasoma have bands of pale-gray to white/off-white tomentum, the legs are never (as opposed to commonly) entirely reddish orange from trochanters to tarsi, and the pseudopygidial area of the female is never (as opposed to commonly; Fig. 26D) reddish orange, and in T. oblongimacula the T1 discal patch is broadly rounded laterally and rod-shaped. Etymology The specific epithet was inspired by the holotype’s (partially) red axillae, which in the original description were described as “dentiform, curved, [and] acute” (Cockerell 1921). Rhodo- comes from the Greek ‘rhódon’ (meaning ‘rose’), and dontus comes from the Greek ‘odṓn’ (meaning ‘tooth’).

T1 with basal and apical transverse bands interrupted medially (former more widely than latter) (T1 with apical transverse band narrowed medially in T. junctus holotype and allotype and multiple non-type specimens) and subparallel, discal patch transversely oblong (verging on widely trapezoidal in T. rhododontus holotype). T2–T4 with apical transverse bands complete and medially somewhat removed from apical margins of terga, that of T2 with pair of basomedially convergent anterolateral extensions.
