Triepeolus alvarengai Moure 1955

Triepeolus alvarengai Moure, 1955 Fig. 13A Triepeolus alvarengai Moure, 1955: 126 (♀). Triepeolus alvarengai – Onuferko et al. 2024: 7, figs 1a, 2, 3a (redescription of female, description of male). Proposed common name Alvarenga’s triepeolus. Diagnosis The following morphological features in combination tell T. alvarengai apart from all other Triepeolus in the simplex species group: the mesoscutum has well-defined paramedian bands (Fig. 13A); the T1 basal band is arched, continuous with (and indistinguishable from) the lateral longitudinal bands, and mesally concave on each side, such that the discal patch is semicircular (Fig. 13A); the T1 apical transverse band (if present) is not more narrowly interrupted medially than the basal band (Fig. 13A); and T2–T4 have complete apical transverse bands of yellow tomentum that are about as broad as (if not broader than) the bands on T1 and do not have basomedially convergent anterolateral extensions (Fig. 13A). Specimens in which T1 has only a basal band or pair of anterolateral patches of pale tomentum (as opposed to both basal and apical transverse bands) may be confused with T. mexicanus or T. nemoralis, but in T. mexicanus pale tomentum on the mesoscutum is restricted to the lateral and posterior margins and in T. nemoralis the mesoscutum has a large anteromedial ovate patch of yellow tomentum, which may be sparser medially such that the patch is suggestive of ill-defined paramedian bands. Specimens in which T1 has an apical transverse band may be confused with T. eumeniformis sp. nov., but in T. eumeniformis the T1 basal band (if present) is more widely interrupted medially than the apical transverse band. Additionally, T. alvarengai can easily be separated from T. eumeniformis and T. mexicanus by geography; the former is known only from Brazil whereas the latter two species are known only from North and Central America.
