Holotype, ♂: Indonesia, Irian Jaya (Jayapura), Cyclop Mts. 25–29. XII. 2009 (S 2°32, E 140°28) [Coll.RC 16–130]. Collected by Viktor Sinjaev. Purchased by the author from Anton Kozlov of Russia.
Description. The description of coloration is based upon the dead dried specimen, however based upon other photographs of the genus Nanophyllium Redtenbacher, 1909; it is assumed the coloration has not changed drastically since death. Dark wings and a wide abdomen (maximum width 11mm) are notable characteristics. Profemora, mesofemora, and metafemora all with large rounded disk-like interior and exterior lobes help to characterize this species.
Coloration. Overall body coloration a dark brown save for a pale stripe running the length of the medial sagittal plane from the anterior of the head capsule to the mesothorax. A similar colored stripe can be found on the ventral surface running from the prosternum to the anterior of the metasternum. Tegmina of a similar dark brown as the body. Alae a slightly lighter brown than the body and relatively transparent. Antennae darker brown than the overall body coloration and similar to the dark brown on the head capsule. Granulation on the body generally has a lighter color than the surface it is found on. The tarsi on each leg has a slightly green coloration versus the overall brown coloration found throughout.
Morphology. Head capsule as long as wide (length-width ratio 1:1). Vertex irregularly granulose with the majority near the posterior, including the posteromedian and clear protuberances near the compound eyes and posterior to the antennal field. Compound eyes protruding and ovular, three well developed yellow ocelli are present as well in the center of the head. Antennae long and slender with segments rectangular in shape, covered in setae each as long as the segments are wide. Antennae contain twenty-one segments (including the scapus and pedicellus) with each segment of segments XI–XIX twice as long as each segment from III–X. Pronotum as wide as long with rather parallel lateral margins, a concave anterior and a convex posterior. Surface slightly granular, more so near the pale stripe running along the medial sagittal plane. Prosternum irregularly granulose but with granules of relatively even size. Mesopraescutum wider than long (length-width ration 1:1.3) gradually narrowing towards the posterior. Lateral margins of mesopraescutum are a granular surface that is not quite developed enough to represent spiniform tubercles, anterior end slightly more granular. Surface slightly granular and only slightly raised along the medial sagittal plane. Mesopleurae only gradually diverging, armed with a single spiniform tubercle on the anterior edge. Surface of mesopleurae are marked slightly with irregular granules and pits of varying sizes. Ventral aspect of mesosternum entire surface covered in irregularly spaced granules. Slightly larger granules located along the medial sagittal plane. Tegmina (length 6.2 mm, maximum width 2.9 mm) very small not even extending to the posterior of the metathorax. Alae (length 28.4 mm), well developed, oval fan configuration. Exposed section of folded alae only slightly sclerotized. Abdominal segment II tapering, III gradually widening, IV strongly angled with a natural fold onto the dorsal surface, V the widest segment, V– VII gradually tapering, VIII with parallel sides, IX tapering towards apex, X slightly widening towards the apex. Anal segment longer than wide, with a rounded apex. Genitalia, poculum broad and starting halfway through abdominal segment VIII and ending in a broad rounded apex that reaches the anterior of segment X. Cercus long and slender with slightly wider posterior, overall shovel-shaped with sides curled in more so on the anterior end. Vomer long and broad with sides gradually converging. Profemora with large rounded interior and exterior lobes. Exterior lobe almost at a right angle and wider than interior. Interior lobe with three small underdeveloped points. Protibiae lacking an exterior lobe, interior lobe roundly triangular spanning the entire length of the protibia. Mesofemora: exterior lobe gently rounded, interior lobe strongly rounded, smooth, and twice as wide as exterior lobe. Interior and exterior lobe of metafemora gently rounded with interior lobe wider. Mesotibiae and metatibiae lacking lobes.
Measurements [mm]: Length of body 39.9, length/width of head 2.4/2.4, length of pronotum 2.1, length of mesonotum 2.0, length of tegmina 6.2, greatest width of tegmina 2.9, length of alae 28.4, greatest width of abdomen 11.0, length of profemora 7.6, length of mesofemora 7.0, length of metafemora 8.0, length of protibiae 4.1, length of mesotibiae 5.5, length of metatibiae 7.3, length of protarsi 4.2, length of antennae 19.6.
Etymology. The new species is named in honor of Stella Williams, a passionate entomologist from King City, California, United States, with a proposed vernacular name of Stella’s Leaf-insect.
