4DC430C27F9452A4B1DC3AEB59CF55FB.taxon	diagnosis	Diagnosis. Prochasma diaoluoensis is distinguished from its congeners by the following characteristics: 1) Valvae with a deep excavation on dorsal side near apex, basally adjacent a brush of modified setae present, absent in other species (Sato 2023, in litt.); 2) Apex of uncus very short, not narrowly elongated; 3) female genitalia with an elongate, funnel-shaped, sclerotized structure on posterior part of bursa copulatrix and a spoon-shaped lamella postvaginalis; and 4) Ante- and postmedial lines reduced to small denticles, bordered by broad, white lines, more conspicuous than in the congeners. The latter two features are found, but less expressed, also in some other species. The same can be stated about the horizontal, yellow band, traversing both forewings, which is most conspicuous in P. mimica, less conspicuous in Prochasma diaoluoensis, but often present, at least in traces, also in the other congeners. Generally, the new species is, though more vividly coloured and with more strongly contrasting pattern, rather similar to its congeners, with exception of P. albimonilis which lacks the yellowish ground colour and has homogenous, dark grey pattern elements, almost not separated into basal, medial and postmedial areas. The female genitalia of Prochasma albimonilis are similar to P. diaoluoensis in the posterior part of bursa, which is also roundly extended on right side, but the sclerotized part is not funnel-shaped but rather broadly tube-like (Sato 2019, fig. 40). It may even be a functional colliculum. In male genitalia, a narrow dorsal incision is present near apex of valvae in Prochasma albimonilis, but the valvae are broader, especially the sclerotized costal side, and more densely setose.	en	Liu, Bo, Stuening, Dieter (2024): Review of the genus Prochasma Warren (Geometridae, Ennominae, Boarmiini), with description of a new species from Hainan, South China.

4DC430C27F9452A4B1DC3AEB59CF55FB.taxon	description	Description. Forewing length: male 12.2 - 13.2 mm; female 12.9 - 13.6 mm. Head. Antennae bipectinate on basal two-thirds in males, rami long, length of longest rami about 9 times the diameter of the flagellum segments, filiform in females. Frons not protruding, covered with short scales, upper half pale, lower half dark. Labial palpus curved upwards beyond frons, covered with intermingled, dark and pale scales and longer hair-scales. Vertex with pale scales, a few dark scales near antennae. Thorax. Patagia and tegulae with lamellar, dark and pale scales, with longer, dark hair-scales on tegulae only, ventrally thorax covered with pale yellow hair-scales. Legs slender, pale, chequered black, hind tibia slightly dilated, with a pale scent brush in males. Forewings with apex angled, termen smoothly curved, without fovea in males. Hindwing with apex rounded. Wings yellow, covered with extensive black scales. Fringes with alternating yellow and smaller black parts. Forewing yellow, with distinct dark markings. Antemedial and postmedial lines both appear as consisting of a few black denticles or dots between M 1 and CuA 2, bordered by a broad, white band. In females, the denticles are more tooth-like. Submarginal line white, very fine, zigzag-shaped. Area between M 3 and CuA 1 appears as a yellow, horizontal band, with or without a few small black spots. Discal dot oval, black, faintly visible. Dark band on inner side of postmedial line of hindwing narrow, reaching from discal dot to inner margin. Dark band on outside broader, the width variable between individuals, slightly broader in females. Submarginal line visible, intermittent, weaker in hindwings. Underside similar to upperside, but more blurry and paler. Venation (Fig. 1). Forewing: R 1 and R 2 coincident; R 1 + R 2 arising from upper vein of cell, then shortly anastomosing with Sc, and running almost parallel to the long stem of R 3 - 4; stem of R 3 - 5 arising shortly before anterior angle of cell; M 2 from the middle of the discocellulars; CuA 1 from before posterior angle of cell. Hindwing: Sc + R 1 running closely parallel but not anastomosing with upper vein of cell at base; Rs from before anterior angle of cell; CuA 1 from before posterior angle of cell; 3 A absent. Pregenital abdomen. Dorsally scaled pale yellow, with a large black spot on each tergite. Ventrally with pale yellow hair-scales. Tympanal organs and a modified setal comb present, the latter as described in the generic description. Tergite and sternite of segment 7 short, length about 2 / 5 of width. Tergite and sternite of segment 8 elongate, length slightly greater than width in males, broader in females. Male genitalia. Uncus triangular, base broad, with short setae dorsally, apex very short, not narrowly elongated. Gnathos with strong lateral arms, central part strong, rectangular, with rounded tip. Juxta rectangular, sclerotized, apex slightly narrowed. Saccus V-shaped, slightly extended. Valvae elongated, apically narrowed ventrally, tip rounded, with a deep excavation on dorsal side. Valve lamina proximally membranous, distally densely covered with setae, without a typical cucullus, with an oblique, sclerotized ridge between both parts. A tuft of long, curved, modified setae, tubular at base, distally flattened, present dorsally near the apex of each valva. Costa straight, sclerotized, basally slightly broadened, distally not reaching tip of valva, ending at excavation. Sacculus sclerotized, distally with a short, tooth-like process, protruding from ventral margin of valva at 3 / 4 of its length. Aedeagus cylindrical, apically broadly elongated and sclerotized on one side. Cornutus short, not stick-like, apex tapering, with bulbous base. Female genitalia. Ovipositor short, papillae anales narrow, tapering towards apex, covered with short setae. Anterior apophyses short, about 2 / 3 length of posterior apophyses. A thin needle-like sclerite, roundly enlarged anteriorly, present between the bases of posterior apophyses. Lamella postvaginalis large, spoon-shaped. Introitus bursae funnel-shaped, slightly sclerotized. Posterior part of bursa elongated, membranous, distally roundly extended on right side; outside with a posteriorly funnel-shaped sclerotized structure formed by a broad sclerite which consists of lamellar plates folded three times, with unknown function (see Figs 11 - 14). Anterior part of bursa slightly broader than posterior part, but no clear demarcation visible.

0EFF45D0CAB951D8B623F9FA01FAFD18.taxon	diagnosis	Diagnosis. The genus Prochasma Warren currently comprises a total of eight species, including the newly described species presented in this study. These species are united by an apomorphic character, a tuft of well-developed, basally narrow, distally broad and curved, upright scales with metallic gloss on the posterior part of mesothorax in both sexes. This character is unique and distinguishes Prochasma from other genera of the tribe Boarmiini, though curved, light-reflecting scales also occur in a number of other geometrid groups; however, these scales are not arranged as an upright brush and other characters such as antennae, transverse lines, fovea (present), venation, male and female genitalia etc. are quite different. There is no genus comparable in size and pattern known to us, with which Prochasma could be confused.	en	Liu, Bo, Stuening, Dieter (2024): Review of the genus Prochasma Warren (Geometridae, Ennominae, Boarmiini), with description of a new species from Hainan, South China.

0EFF45D0CAB951D8B623F9FA01FAFD18.taxon	description	Generic description. A generic description was provided, besides the original description by Warren (1897), only by Holloway [1994] and by Sato (2019); the latter partly repeated the characters mentioned by Holloway, but added some new features. Herein, we summarize these already published characters of Prochasma, with a few corrections, and add new-found, unpublished features.	en	Liu, Bo, Stuening, Dieter (2024): Review of the genus Prochasma Warren (Geometridae, Ennominae, Boarmiini), with description of a new species from Hainan, South China.
