comb. nov.

Dictyotrypeta incisa (Wulp) View in CoL , new combination

Fig. 35

Acrotaenia incisa Wulp 1899b: 415 View in CoL .

Acrotaenia (Pseudacrotaenia) incisa: Hendel 1914: 59 View in CoL .

Pseudacrotaenia incisa: Aczél 1950: 270 .

Baryplegma incisa: Norrbom et al. 1999: 105 .

This species was transferred to Baryplegma View in CoL by Norrbom et al. (1999) when they placed Pseudacrotaenia in synonymy with Baryplegma (Acrotaeniini) View in CoL , but it is here classified in Dictyotrypeta (Eutretini) View in CoL . Although its wing pattern ( Fig. 35) is almost radiate and somewhat resembles the patterns of some Baryplegma species , it is more similar to those of many Dictyotrypeta species. Vein R 4+5 is extensively setulose dorsally (occurs in both genera), the parafacial has a brown spot at the level of the base of the antenna (occurs in all Dictyotrypeta species , but no Baryplegma View in CoL ), the frons is setulose medially as in most Eutretini View in CoL , whereas it is bare in Acrotaeniini View in CoL , the eye has a single narrow horizontal stripe aligned with the parafacial spot (synapomorphy of Dictyotrypeta species ), cell r 4+5 has a bulla anterodistal to crossvein dm-cu (variable in Dictyotrypeta View in CoL , absent in Baryplegma View in CoL ), and the length of the posteroapical lobe of cell bcu is less than half the width of the cell (it is longer in Baryplegma View in CoL ).

Distribution. Mexico (Chiapas, Guerrero, Veracruz) and Guatemala. The specimens listed below include the basis for the Mexican records other than the type locality reported by Norrbom et al. (1999), as well as the first records from Guatemala.

Biology. Host plants have not been reported previously for this species. We reared it in Guatemala and Mexico from flowerheads of Smallanthus maculatus (Cav.) H. Rob. ( Figs. 114–115) and S. riparius (Kunth) H. Rob. ( Asteraceae : Heliantheae : Milleriinae ).
