Mictocommosis lesleyae Austin & Dombroskie, 2020 sp. nov. – Wikispecies link – ZooBank link – Pensoft Profile
Diagnosis
Wing pattern alone is sufficient to identify Mictocommosis lesleyae (Fig. 13B, C). It lacks the complex scaling patterns on the dorsal surface of the hindwing present in M. godmani (Walsingham, 1914), the only other species of Mictocommosis currently recognized in the Neotropics (but see remarks below).

Description
Male (n = 1). Head. Scales on vertex thin, leaden gray, pale orange-yellow laterally. Scales on frons concolorous, but absent ventrally. Labial palpus approximately 1.5 × width of compound eye, thin; scales absent laterally and medially, but white ventrally. Proboscis naked at base, fine setae present laterally. Scape leaden gray dorsally, pale yellow to orange-yellow ventrally. Antenna massively thickened, slightly compressed laterally; sensillae approximately width of flagellomere, tightly appressed. Dorsum of flagellum with one row of scales per segment; orange-yellow to 0.8 × length of antennae, then dark gray for 0.1 ×, then pale yellow for 0.1 ×, terminal segment dark gray; ventral surface of flagellum naked. Ocellus large, separated from compound eye by approximately 0.5 × width of ocellus. Chaetosemata 0.5–2 × length of scales on vertex. Thorax. Dorsum of pro- and meso-thorax ashy gray, intermixed with orange-yellow scales; dorsum of metathorax orange-yellow; tegulae leaden gray. Foreleg with lateral surface with ashy gray scaling, tarsi intermixed with white scales; midleg pale yellow, with ashy gray scales restricted to tarsi; hindlegs missing; medial surface of legs pale yellow to white. Forewing (Fig. 13C) broad, costa evenly and gently curved throughout entire length; FWL 6.0 mm. Dorsal surface of forewing beautiful, unmistakable, with ground color deep red-orange, heavily suffused with orange-yellow; two silver lines running parallel to costa from base to 0.33 × length of costa, separated by an equally-wide yellow streak; median area of forewing heavily peppered with brilliantly bicolored scales, (ashy gray basally, white terminally), patches of black scales scattered apically; three silver fasciae present towards outer margin: most basal of three extending from 0.6 × length of costa to just below termen, composed of silver scales, separated from next fascia by an orange gap; next fascia faint, composed primarily of same bicolored present in medial area of forewing, separated from terminal fascia by deep red scales; terminal fascia extending from 0.8 × length of costa to 0.5 × length of outer margin, composed of silver scales; orange scales beyond to fringe. Fringe with short scales red-orange, long scales silver. Dorsal surface of hindwing orange, becoming slightly darker apically; fringe concolorous, longer scales slightly paler. Ventral surface of forewing orange, with scattered black scales in median area. Ventral surface of hindwing concolorous with dorsal surface. Abdomen. Vestiture orange, leaden gray at base. Genitalia (Fig. 20E) with uncus broad, well-developed, expanded to broad, flattened apex with shallow notch, covered in robust spines on lateral edge of neck near apex and apex itself; socii well-developed as large pads thinly-connected to tegumen, densely covered in thick spines; tegumen and gnathos weak, gnathos without terminal plate; transtilla weak with long medial process; valvae elongate, triangular; sacculus with spine-like extension extending into basal cavity; juxta with shallow notch; phallus short, rounded basally, downturned and deeply-notched apically, with blunt, thorn-like cornutus.
Female (n = 3). Head. As in male except lateral surface of labial palpus with scaling pale yellow to white. Thorax. As in male except hindlegs with femur and tibia pale yellow to orange, tarsi leaden gray and white. Dorsal surface of forewing (Fig. 13B) with small white patches of scales in center of two of black patches in median area of forewing, which could be interpreted as false eye spots, FWL 6.0–6.5 mm (mean = 6.3; n = 3). Dorsal surface of hindwing with a few silver scales on costal edge; a small black patch of scales along Cu2 near fringe in two of three paratypes, a dark patch of deep red-orange scales in same area of third paratype; frenulum with three or four bristles. Abdomen. Vestiture as in male. Genitalia (Fig. 21E) with papillae anales triangular posteriorly, anterior lobe narrowed; apophyses both approximately 0.75 × length of sternum VII; sterigma broad, quadrate, well-sclerotized, covered in minute spines; colliculum a small sclerotized plate; ductus bursae uniform in width throughout, twice-coiled; ductus seminalis arising near base of ductus bursae; corpus bursae large, ovoid; signum a short, rounded nub; with long, paired scobinate extensions of finely-spined basal plate to bottom of corpus bursae; capitulum absent.
Etymology
This beautiful species is named in honor of KAA’s mother, Lesley, for her unwavering support and love.
Distribution
Mictocommosis lesleyae is known from two localities in the Dominican Republic (Fig. 27): at high elevation on Sierra Martin Garcia in the south and at low elevation in Parque Nacional de Los Haitises on the northern coast.
Biology
Nothing is known of the biology of Mictocommosis lesleyae. Like other members of the Mictopsichia group of genera, it is presumed to be diurnal but may also come to lights. The four known specimens were collected in July.
Remarks
Unfortunately, the phallus of the holotype was lost prior to slide mounting. With the description of Mictocommosis lesleyae, there are now two described species of Mictocommosis in the Neotropics. Two more, Mictopsichia ornatissima (Dognin, 1909) and Mictopsichia buenavistae Razowski, 2009 may also belong to this group. Mictopsichia ornatissima was not examined nor dissected by Razowski (2009)[1] and appears to be closely related to Mictocommosis godmani (Walsingham, 1914), a possible relationship which was alluded to by Walsingham. Mictopsichia buenavistae is known only from a female. Its genitalia are similar to known females of Mictocommosis and its similarity to Mictopsichia ornatissima was noted by Razowski (2009)[1]. Whether or not these Neotropical species truly belong to Mictocommosis remains to be seen. We believe it is unlikely, as the type species of Mictocommosis (Simaethis nigromaculata Issiki, 1930) was described from Japan and possesses a basally scaled proboscis (Diakonoff 1977[2]), a character not seen in Mictocommosis lesleyae, nor any other known tortricid genus with the exception of Thaumatographa Walsingham (Diakonoff 1977[2]). One additional species, Mictopsichia jamaicana Razowski, 2009, may also belong to this group of Neotropical “Mictocommosis”, but we were unable to examine the holotype and thus choose to retain it in Mictopsichia.
