Moerarchis Durrant, 1914 nuevo para China, con descripción de una nueva especie (Lepidoptera: Tineidae) Resumen Se registra por primera vez para China el género Moerarchis Durrant, 1914. Se describe una nueva especie Moerarchis rectitrigonia Yang & Li, sp. n. basada sobre los especímenes colectados en las provincias de Anhui, Guangxi, Hainan y Zhejiang. Se proporcionan fotografías de los adultos y genitalia. PALABRAS CLAVE: Lepidoptera, Tineidae, Moerarchis, nueva especie, China. Introduction The genus Moerarchis was established by DURRANT (1914) with Tinea australasiella Donovan, 1805 as the type species. It is a small genus consisting of ten named species: M. australasiella, M. clathrata (Felder & Rogenhofer, 1875), M. hypomacra (Turner, 1923), M. inconcisella (Walker, 1863), M. lanosa (Diakonoff, 1949), M. lapidea Turner, 1927, M. placomorpha Meyrick, 1922, M. pyrochroa (Meyrick, 1893) that are distributed in the Australian Region; M. anomogramma (Meyrick, 1930) occurs in both the Oriental and Australian regions; and M. galactodelta (Diakonoff, 1968) is only known from the Philippines (ROBINSON, 2008, 2009). Moerarchis is diagnostic for the dense antennal pecten, the strongly developed brush on the second segment of the labial palpi, the absence of the retinaculum, the stout frenulum comprising a bunch of short bristles; the uncus lobes widely fused and bearing dense spinules, the slender and clubbed saccus and aedeagus in the male genitalia; the elongate ovipositor, and the reduced ventral rami of the apophysis anterior in the female genitalia. Prior to this study, no Moerarchis species has been recorded in China. We herein newly record this genus in China and describe one new species, M. rectitrigonia Yang & Li, sp. n. Morphological terms used in description follow ROBINSON & NIELSEN (1993). Whole body dissection follows the methods described by LEE & BROWN (2006), and genitalia dissection follows LI (2002). The type specimens are deposited in the Insect Collection, College of Life Sciences, Nankai University, Tianjin, China. 135

MOERARCHIS DURRANT, 1914 NEW TO CHINA, WITH DESCRIPTION OF ONE NEW SPECIES narrowed to rounded apex; costal margin straight, ventral margin slightly convex basally, oblique distally; inner surface with thick setae except a right-triangular, membranous, smooth basal area. Juxta weakly sclerotized, contiguous with inner surface of valva, forming a narrow labium on each side of aedeagus. Aedeagus slender, clubbed, 2.5 x length of saccus; cornutus absent. Female genitalia (Fig. 10): Corethrogyne absent in seventh segment. Ovipositor very long, 0.65 x length of abdomen. Apophysis posterior very long, 2.0 x length of apophysis anterior. Eighth tergite rectangular, dorso-medially with a gourd-shaped microtrichiate area. Eighth sternite slender, ribbonlike, slightly broadening anteriorly, with a small triangular notch on posterior margin and a larger triangular notch on anterior margin. Ostium at notch on posterior margin of eighth sternite. Antrum not differentiated from ductus bursae; ductus bursae 1.2 x length of corpus bursae (including antrum), narrow; a small ringlike colliculum at junction of ductus bursae and corpus bursae ductus, inception of ductus seminalis at margin of this ring. Corpus bursae large, pyriform, without signum. Diagnosis: The new species is similar to M. lanosa, but can be distinguished from the latter by the forewing venation with R 4 and R 5 free from each other, the hind wing Rs to costa, and the rightangled triangular valva without rim on inner surface in the male genitalia. While in M. lanosa, R 4 and R 5 are shortly stalked in the forewing, Rs terminates at apex in the hind wing (DIAKONOFF 1949: 315, Fig. 6), and the isosceles triangular valva has a transverse, sinuate rim dentate in middle in the male genitalia (DIAKONOFF 1949: 313, Fig. 3). The female genitalia are similar to those of M. australasiella (ROBINSON & NIELSEN 1993: 249, Figs 531-2), but M. australasiella is patterned with large black and white fasciae and patches on the forewing (COMMON 1990: Pl. 3.6), which can well separate it from the new species. Distribution: China (Anhui, Guangxi, Hainan and Zhejiang). Etymology: This specific name is derived from the Latin prefix recti-, meaning straight, and the Latin word trigonius, meaning triangular, referring to the right-triangular valva. Remarks: The new species is distinguishable from its congeners by having a distinct forewing pattern, which is usually quite different among members of Moerarchis. We were unable to examine the type specimens of the named species, but have carefully checked the original descriptions of all the described species and the available illustrations of some adults and genitalia for comparison. Though the forewing venation varies between the two sexes in this species (CuA 1 is fused with M 3 in male but free in female), and the seven female specimens were not collected in the same locality as the five male specimens, we match females with males since they share a same forewing pattern.
