Kirejtshuk, A. G.: New taxa of Nitidulidae (Coleoptera) from the Indo-Malayan fauna

5 Elytral length much more than their combined breadth; dark pattern (if visible) on dorsum with more or less contrasting margins, with a dark and a slight stripe on each elytron at both sides of scutellum; penis trunk widened towards its excised apex. 3.3-7.0 mm. — Morocco, Algeria, Tunisia (= henorii FAIRMAIRE, 1867, syn. n.; = algiricus Pic, 1894, syn. n.)* C. chloroticus FAIRMAIRE, 1860 — Elytral length subequeal or hardly more than their combined breadth ; dark pattern on dorsum (if visible), as a rule with indistinct margins and without consequent stripes of dark and light colour, or with only a subsutural light stripe on each elytron; penis subparallel-sided with apex nearly rounded off or weakly projected and abrupt. 3.0-6.1 mm. — Palaearctic Region. (= dorsalis REITTER, 1884, syn. n.)** C. luteus (FABRICIUS, 1787) Xenostrongylus philippinensis sp. n. (Figs. 135-137) Material. 1 çf holotype (MHU) and 1 çf, paratype (ZIN): "Philippinen, Mindoro, Mangarin, 11. 1917, S. BÖTTCHER". Male, holotype. Length 2.2, breadth 1.6, height 0.7 mm. Oval, dorsum evenly convex; yellowish brown; shiny; dorsum contrastingly pubescent with short dense and relatively stout yellowish hairs covering the surface, except oval central mark behind scutellum where hairs ever so less contrasty; body sides not ciliated. — Head short and flat, its frons scarcely projecting with straight anterior margin and side corners widely rounded off. Surface with shallow punctures considerably smaller than eye facets separated by distance equal to 1/4-2/3 puncture diameter, interstices smooth and shiny. Antennae 3/4 as long as head wide, their oval club 1.3 times as long as wide, composing about 2/5 of total antennái length. — Pronotum without any trace of basal border, but side ones feebly raised, its corners very widely rounded off. Surface about same as on head but punctures denser, larger and more distinct. — Scutellum triangular, its surface almost as on head but with less distinct and denser punctures. — Elytra with shoulders hardly expressed and subsutural lines closely approaching suture. Surface as on pronotum but with denser punctures. — Pygidium with outer edge gently and widely rounded off. — Ventral surface approximately like dorsal on head, with fine and long, non-contrasting yellow hairs. Prosternai process narrow, weakly widened before its rhomboid apex, 2/5 as wide as antennái club. Distance between intermediate coxae twice longer than that between fore ones and that between hind ones 4 times longer than the latter. Metasternum flat with almost hind margin between hind coxae. Caudal marginal line of hind coxal cavities following closely to hind edge of coxae. Last abdominal sternite shaltowly emarginate at apex. — Tibiae wide and depressed, almost as wide as antennái club. Femora twice wider than tibiae. Fore tarsi nearly 2/3, and intermediate and hind not more 1 /2 as wide as fore libia. Claws simple short and thick. — Genitalia: Aedeagus moderately sclerotised. Variation. The second specimen (paratype) is very similar to the holotype but is slightly larger with its length of 2.4 mm. * Evidence of new synonymy of C. chloroticus became dear to the author after having studied some specimens from Algeria, Tunisia and Morocco which show a great degree of variation and comparison of their characters with the original descriptions of C. chloroticus and its variations described as "distinct" taxa. As a result the complete synonymy may be listed as follows : Cychramus chloroticus FAIRMAIRE, 1860, Ann. Soc. Ent. France, (3) 8: 168; = henoni FAIRMAIRE (nec REITTER), 1867, Ann. Soc. Ent. France, (4) 7: 395, syn. n. = chloroticus var. fairmairei Pic, 1894, Feuille Jeunes Nat., 44; Exchange, 10: 134. = algiricus Pic, 1894, Exchange, 10: 133 et 134; syn. n.; = testaceus Pic, 1894, Exchange, 10: 133; = henoni REITTER (nec FAIRMAIRE), 1895, Wien Ent. Zeit., 14: 164. The author has knowledge of specimens with the following labels: 1 ex.: "Algir.Bou Berak", "chloroticus FRM.,CO11. REITTER" (TM); 1 ex.: "Algir", "chloroticus FRM.,CO11. REITTER" (TM); I ex.: Morocco, "Alg.", "Atlas, Dovup", "chloroticus FRM., coll. REITTER" (TM); 1 ex.: "Tunis, Ain Draham, B. v. BODEMEYER", "chloroticus FRM., coll. REITTER" (TM); 1 ex.: "Algir, coll. REITTER", "Cychramus fairmairei Pic", type, "Algirien, coll. REITTER" (TM); 1 ex.: "Algeria, coll. REITTER", "Cychramus henoni FRM." (ZIN); 1 ex.: "Ph. Ville, DEBROCHER" (ZIN). This species differs from C. luteus in its more slender body shape, particularities of dark pattern on dorsum (Fig. 131) as well as in its male genital structures, including sharp dorsoventral curving of tegmen (Figs. 132-134). ** Looking through hundreds of specimens of the most common Cychramus species from various parts of the Palaearctic Region enabled me to reach a conclusion on the synonymy of C. luteus and C dorsalis. Dark specimens, especially among females occur in Japan, the Primorie Territory, Sakhalin and Kuril Islands and other Asiatic and East European localities in the USSR.
