“…The arrangement, number and morphology of the primary setae in the larvae may be important for the identification of species and genera and provide characters of systematic value (Fracker 1915;Peterson 1966;Scoble 1995;Stehr 1987). In Austrandesiina, both body and head chaetotaxies of A. ignicans are the same as that of F I G U R E 1 3 Relationship between age-specific survival, l x (dashed line), and a number of offspring per day, m x (continuous line), of Anicla ignicans originated from larvae fed on an artificial diet (25 ± 1 C, 70 ± 10% relative humidity and a 14-h photophase).…”

“…In any case, to evaluate the chaetotaxy, first-instar larvae should be selected; although the setae are better seen in mature larvae, the first instar is preferable for comparisons because the chance of finding only the primary setae in this instar is higher. Primary setae are more constant in their positions than secondary setae that may be present in other instars, which would justify their use (Fracker 1915).…”

The subgenus Anicla, commonly known as green cutworms, harbours some of the owlet moths (Lepidoptera: Noctuinae), whose larvae are notable for their economic importance. Knowledge of the immature stages for this group is available for three of the nine described species. Anicla infecta Ochsenheimer, 1816 is widely distributed in the Americas and is especially abundant in agricultural ecosystems. However, in the Neotropics, its economic damage can be confused with sympatric species, including Anicla ignicans (Guenée, 1852), whose distributions overlap in most parts of the American continent. In this sense, here, the identity of A. ignicans is investigated through its geographical distribution, based on molecular and morphological data. Additionally, the morphological and behavioural traits of immature stages were described in detail, information about its geographical distribution and larval host plants was gathered, and the species' biological parameters from larvae reared on an artificial diet were determined. Anicla ignicans is distributed throughout the Neotropical region, preferably in areas with xeric and/or grass‐dominated ecosystems. The eggs present valuable characters to distinguish A. ignicans from other owlet moth species, such as the reduced number of ribs, the way the micropyle openings are arranged and the shape of the aeropyles. However, the larvae show very similar chromatic polymorphisms to other Anicla species. Although A. ignicans prefer to feed on grasses, it was observed that more than 85% of the larvae that were fed with a modified bean‐based Greene diet survived. Additionally, the percentage of time for each phase of development obtained here is very similar for the different species of Anicla, regardless of the temperature or feeding of the larvae.

“…The family classification of the Gelechioidea has been unstable and constantly undergoing major and minor alterations since the characterization of the superfamily by Fracker (1915) and Mosher (1916). Bucheli (2009) gave a detailed summary of older classifications.…”

“…A typical example of a gelechioid genus with unstable history of systematic position is Coelopoeta Walsingham, 1907. This genus, originally based on a single species, C. glutinosi Walsingham, 1907, was placed in Hyponomeutidae [sic] (Walsingham (1907). Barnes & Busck (1920) moved it in Elachistidae in the Gelechioidea as defined by Fracker (1915) and Mosher (1916). Braun (1948) followed this concept, without giving any concrete characters apart from the general mention of "mouth parts, antennal pecten, and general configuration of venation".…”

Systematics and taxonomy of the gelechioid subfamily Coelopoetinae are reviewed. Following the current classification, this group is considered to form its own monotypic subfamily in Pterolonchidae with one recognized genus, Coelopoeta, after a convoluted and, in part, arguably conjectural, historical systematic treatment. On morphological basis (appearance, male genitalia) and with support from DNA barcodes, the genus is divided into two discrete units probably meriting recognition as separate genera. The species groups are informally treated as the nominate C. glutinosi species group, and the C. fissurina species group. In the absence of knowledge of females or the biologies of any of the species of the C. fissurina group, species of both groups are here provisionally included in Coelopoeta. In total, 10 species are recognized, seven of which are here described as new: C. glutinosi species group: C. alboflava Kaila, sp. nov., C. aprica Kaila, sp. nov., C. aurora Kaila, sp. nov., C. fulminea Kaila, sp. nov. and C. sariae Kaila, sp. nov.; C. fissurina species group: C. fissurina Kaila, sp. nov. and C. valalbui Kaila, sp. nov. The three previously known species, C. glutinosi Walsingham, 1907, C. maiadella Kaila, 1995 and C. phaceliae Kaila, 1995 are redescribed. All three of these species belong to the glutinosi species group. A lectotype is designated for C. glutinosi Walsingham, 1907. Some southwestern Coelopoeta species are potentially under threat of decline or even extinction due to the apparently increasingly intense and frequent forest fires. This threat is significant as the species with known life histories spend their entire life cycles above ground in low vegetation.
