These specimens are the only known representatives of this species.</p><p>Etymolgy.</p><p>Named after its lepidopteran host species.</p><p>Diagnostic description</p><p>also see key below. This species can be recognized as  Iconella based on the features first described by Mason (1981) and further expanded and discussed in Fernandez-Triana et al. (2013, 2020), namely: a sinuated vein cu-a in the hind wing and the presence of a median longitudinal carina on the propodeum.  Iconella melitaraevora is very distinctive from most other described species in the New World (Fig. 1).  Iconella isolata, a species recorded from the Caribbean and South America, has much lighter coloration of hind legs and veins in forewing, as well as mostly transparent or whitish pterostigma, with only thin brown margins (pterostigma almost completely brown, with only small whitish spot anteriorly in  melitaraevora). Two species recorded from Central America (Costa Rica and Mexico),  I. andydeansi and  I. jayjayrodriguezae both have mostly transparent or whitish pterostigma, with only thin brown margins (pterostigma almost completely brown, with only small whitish spot anteriorly in  melitaraevora); T 1 width at anterior margin 3.1 × or more its width at posterior margin (T 1 width at anterior margin 2.4–2.6 × its width at posterior margin in  melitaraevora); metatibia with smaller darker area posteriorly and with larger yellow spot on anterior half of first segment of metatarsus (metatibia dark on posterior half and first segment of metatarsus with very small yellow spot anteriorly in  melitaraevora).  Iconella canadensis, recorded from Eastern Canada, has different pterostigma color (mostly transparent or whitish versus mostly brown in  melitaraevora); comparatively smaller ocelli size (ocular-ocellar line 1.6 × posterior ocellus diameter versus 2.0  × melitaraevora); and shorter ovipositor sheath (ovipositor sheath length 0.8 × or less metatibial length versus 1.06–1.12 × in  melitaraevora). Also see key below for additional diagnostic description.</p><p>The most similar species is  I. etiellae, which is the only other species so far recorded from New Mexico, among several other states in the central and western U. S. A. (Rodriguez et al. 2013; Fernandez-Triana et al. 2020). The main morphological differences between these two species are the hind leg color (metatibia entirely yellow and metatarsus almost entirely yellow in  etiellae, metatibia with posterior half dark brown to black and almost entire metatarsus dark brown to black in  melitaraevora); different size of ocelli (ocular-ocellar line 1.6 × posterior ocellus diameter in  etiellae, 2.0 × in  melitaraevora); and T 1 width slightly different (T 1 width at anterior margin 2.4–2.5 × T 1 width at posterior margin in  etiellae versus 2.0 × in  melitaraevora). Additionally, the longitudinal median carina on propodeum is more strongly defined in  etiellae (much thinner and weak in  melitaraevora), although this is a character difficult to assess unless several specimens from both species are at hand and available for comparison. The two species have different recorded caterpillar hosts within the  Lepidoptera family  Pyralidae (Table 1;  Etiella zinckenella,  Melitara junctolineella,  Psorosina hammondi, and  Ufa rubedinella for  etiellae;  Melitara subumbrella for  melitaraevora). There are also molecular differences based on DNA barcodes (Fig. 2) with 43 / 552 bp different base pairs, or a 7.8 % difference, between the two species  melitaraevora (Process ID NACMA 001-24) and  etiellae (Process ID HYCNE 1332-11). The combination of morphology, biology and molecular data allows us to separate and distinguish these two species. It is important to note that there are many undescribed species accessioned on BOLD, that are probably in  Iconella, and the CO 1 sequence data of this species differentiates it from those undescribed.</p><p>Body measurements and proportions (measurements of holotype provided first, followed, between parentheses, by range based on other specimens).

Melitara subumbrella larvae were collected on  O. phaeacantha ( Cactaceae, Fig. 3 B), a mid to high elevation  Opuntia distributed in dryland habitats of North America from Baja California, California, Nevada, Utah, Arizona, Colorado, New Mexico, Chihuahua, Oklahoma, and Texas.  Melitara subumbrella larval feeding causes the host plant cladode tissue to swell and create a shelter, which resembles a “ gall ”, and within which the larvae build tunnels and develop (Fig. 3 B). This behavior and the associated plant-response is typical of shelter-building phycitine larvae that use  Opuntia host plants (authors, unpublished data).</p><p>Twelve  M. subumbrella larvae arrived at the laboratory alive. This number was based on the observation of conspicuous frass emission from host plant pads (Fig. 3 B, C). Ultimate instar  Melitara subumbrella larvae exited the host plant pads and formed puparia within the top 5 cm of soil. This behavior is also typical of  Opuntia specialist phycitine larvae (Mann 1969). Five  M. subumbrella larvae had  I. melitaraevora larval cohorts emerge (Fig. 3 F) and make cocoons within puparia that their caterpillar hosts constructed for pupation (Fig. 3 G; Suppl. material 1). The wasp larvae were gregarious, with a range of 8–20 successfully emergent individuals per caterpillar cohort (x ̄ = 16 wasps ± 4 S. E.). Adult wasps from four of five cohorts emerged successfully, the reason for failed emergence of the final cohort is unknown. The sex ratio was female skewed with 28 females and 19 males reared, overall. However, one cohort had more males than females (9 ♀: 10 ♂).</p><p>We do not know when  I. melitaraevora oviposition took place in the field. But the  M. subumbrella were clearly parasitized upon field collection on 23 August 2023 because they were held in containment for the duration of their development which precludes the possibility that they were attacked by other braconid wasps in transit from Santa Fe County, NM to Austin, TX. We observed larvae from one cohort emerge from the host and pupate on 10 December and another cohort was observed pupating on 18 December. Ultimately, two cohorts emerged on approximately 18 December 2023, the third emerged on 25 December 2023 and the fourth on 27 December 2024 (we did not observe the other two cohorts pupating). So, pupal development time was 7–8 days (N = 2), and total immature development was at least 15–19 weeks (N = 4) under laboratory conditions.</p></div>	https://treatment.plazi.org/id/156F1878106E596E9CA9357904D0B710	Public Domain	No known copyright restrictions apply.
