Hermaeophaga korotyaevi Konstantinov, new species
No full textHermaeophaga korotyaevi Konstantinov, new species (Figs 45–47) Holotype, male. South Korea, GN Prov., Mt Juri Sancheong City, Sicheonmyeon, Sincheonri, 17.V.2000 leg. B. Korotyaev (ZMAS) Body length 1.72 mm, width 1.08 mm. Head and pronotum black with light bronzish tint, as dark as elytra. Antennomeres one, two, and three yellowish, much lighter than rest. Pro- and mesotibiae somewhat darkened, nearly as dark as pro- and mesofemora. Head (Fig. 45) slightly convex in lateral view (frons and vertex form slightly convex line in lateral view). Vertex shiny, without punctures or wrinkles in middle. Supracallinal sulci absent, but head surface bends from antennal calli to vertex thus separating antennal calli from it. Midfrontal sulcus present, well visible only at base. Orbital and supraorbital sulci deep and relatively wide, being most noticeable sulci on head. Suprafrontal sulcus deep. Frontal ridge narrows between antennal calli also narrowing ventrally forming denticle at anterofrontal ridge (Fig. 45). Antennomere two slightly longer than three or four separately. Pronotum slightly swollen anterolaterally, with anterolateral callosity forming acute denticle. Antebasal transverse impression deep in middle, as deep as laterally. Disc with small dense and sharp punctures. Procoxal cavities widely open. Intercoxal prosternal process extends posteriorly beyond coxae. Elytron with well developed humeral callus, widest nearly at middle. Punctures confused, distance between them varies significantly. Larger punctures form irregular striae with smaller punctures placed in between. Elytral slopes nearly vertical at basal one third. Median lobe of aedeagus (Figs 46, 47) slightly narrowing apically, not constricted before apex in ventral view, nearly straight in lateral view with apex strongly bent dorsally. Apex rounded, lacking defined denticle in ventral view. Apical part of longitudinal impression narrows gradually. Comments: Hermaeophaga korotyaevi can be separated from all other Eurasian species of the genus with the help of the following key, where it is in the vicinity of H. mercurialis F. and H. cicatrix Illiger. It can be separated from both of them by the frontal ridge dorsally as narrow as ventrally, forming denticle above clypeus and the third antennomere shorter than the second. Hermaeophaga korotyaevi is also similar to H. dali and can be separated from it by the following characters: the basal antennomeres and the tarsi are much lighter than in H. dali; the apex of the median lobe of the aedeagus is narrowly rounded (it is flat in H. dali); border that limits ventral longitudinal impression broadly rounded, almost flat (it is triangular in H. dali). Etymology: This species is named after B. A. Korotyaev who collected it.Published as part of Lopatin, I. K. & Konstantinov, A.

Etymology The name of the new species is derived from the type locality, Dandeli city. Type material Holotype INDIA • ♂; Karnataka, Dakshina Kannada, Dandeli; 15.236° N, 74.616° E; H.M. Yeshwanth leg.; 10 Nov. 2012; at light; UASB.

Yeshwanth leg.; Ex: Diplocentrum recurvum; UASB. Description Male COLORATION. Yellow to orange yellow, with contrasting black pattern (Fig. 2E). Head: yellow to orangeyellow, with postocular region of vertex black and sometimes with a narrow brown mark on frons along midline; eye silvery with black band along inner margin in frontal view; antennal segments I and II black, remaining segments brown; labium brown. Thorax: pronotal collar and calli with longitudinal black stripes laterally, disc of pronotum with two black stripes close to midline and darkened posterior angles; thoracic venter pale brown, propleura with similar black longitudinal stripe; exposed part of mesoscutum and scutellum yellow to orange-yellow, with lateral black patches at base. Hemelytron: clavus black, with V-shaped yellow region apically; corium yellow to orange yellow, with entirely black exocorium and with three large, almost confluent, longitudinal black patches separated by branches of R+M vein and occupying most of endocorium except base and extreme apex; cuneus yellow to orange yellow with black apical half. Legs: coxae pale brown to pale yellow; femora yellow with darkened apices and a diffuse dark brown ring on apical third; tibiae brown to dark brown, pale yellow medially. Abdomen: yellow to orange yellow, with lateral black patches. SURFACE AND VESTITURE. Dorsum finely punctate; head, pronotum and hemelytra weakly rugose, with yellow, long, erect simple setae, antenna and legs with setae somewhat longer than elsewhere. STRUCTURE. Body elongate-oval, total length 2.5× as long as basal width of pronotum. Head: transverse, with distinctly convex and anteriorly projecting frons; eye sessile, large, occupying half of head height in lateral view, not in contact with anterior margin of pronotum due to well-developed postocular region of vertex; vertex slightly convex; antennal fossa, prominent, round, narrowly separated from eye, located near ventral eye margin; antennal segment I short, subequal to vertex width, tubular and narrowing at base; segment II 1.2× as long as head width, about half as thin as segment I, slightly dilate apically; segments III and IV short, filiform, subequal in length; labium long, reaching abdominal sternite III. Thorax: pronotum 1.6× as wide as long, with collar concave, distinctly wider than diameter of antennal segment I, slightly narrowing towards midline, posteriorly well delimited by an impressed line; calli raised, anteriorly and posteriorly delimited by impressed lines; disc of pronotum slightly raised, trapeziform, with strongly sinuate posterior margin; mesoscutum largely exposed; scutellum slightly longer than exposed part of mesocutum, slightly raised; metathoracic scent gland efferent system reduced, with narrow opening and peritreme (Fig. 25B). Hemelytron: costal margin slightly concave, hemelytron broadest at level with apex of clavus; slightly above cuneus, cuneus about 1.5× as long as wide, with distinct cuneal fracture; primary cell of membrane large, far exceeding apex of cuneus, secondary cell narrow. GENITALIA. Genital capsule short and wide, with a large, posteriorly directed aperture (Figs 17, 18A– B); dorsal margin with very large, spoon-shaped lobe more than twice as long as genital capsule and equipped with groove running towards apex; lateral margins of genital capsule with large, slightly asymmetrical lobes resembling parameres; aedeagus and parameres strongly reduced, parameres almost equal in length, located close to each other on ventral margin of capsule; left paramere as in Fig. 18C–D, right paramere as in Fig. 18E. aedeagus with entirely membranous phallotheca, simple membranous endosoma, and ductus seminis with membranous basal part and sclerotized, spine-like apical part (Fig. 18F). Female Similar to male but slightly smaller. Coloration as in male but vertex with a longitudinal pale brown marking and eye entirely silver, without any black markings. Host Diplocentrum recurvum Lindl. (Orchidaceae) (Fig. 27E). Distribution Southwestern India (Karnataka state). Remarks The new species is most similar to L. pallescens Poppius, 1912 in size, body proportions, vestiture, and general color-pattern but it differs from L. dandeliensis sp. nov. in the pale-brown ground color, the diffuse, weakly expressed dark markings on the dorsum, and the coloration of antennal segment II and tibiae. Lopidolon sordidus is similar to the new species in the contrasting black and orange coloration but differs from it in the largely darkened head, uniformly dark brown antennal segments I–II, reddishbrown tibiae, presence of a pair of uninterrupted black stripes on pronotum running from collar to posterior margin of disc, and longer vestiture.Published as part of Yeshwanth, H.
