MEMOIRS OF THE AMERICAN ENTOMOLOGICAL SOCIETY Volume 117, Number 4, September and October 2006 385 NEW NUMBER 46 THE GENUS DINICA GOZMÁNY (LEPIDOPTERA: TINEIDAE) FROM CHINA, WITH THE Systematics and Biogeography of the Desert Crane Fly DESCRIPTION OF A NEW SPECIES1 Subgenus Tipula (Eremotipula) Alexander (Diptera: Tipulidae) Guo-Hua Huang,2 Min Wang,3 and Toshiya Hirowatari4 by Jon K. Gelhaus. ABSTRACT: The genus Dinica Gozmány, 1965 is recorded from Nanling National Nature Reserve, 236 pages, 100 plates ..... $45 South China. Dinica rhombata sp. nov. is described and illustrated, the first record of this genus from China. The new species is very similar in appearance to Dinica endochrysa (Meyrick, 1935) from Japan, but it can be distinguished easily by the characteristics of the male genitalia: straighter aedeagus, larger subscaphium and slender saccus. Terminology of the male genitalia is briefly discussed. KEY WORDS: Lepidoptera, Tineidae, Dinica, new species, China The genus Dinica was established by Gozmány (1965) with Homalopsycha hyacinthopa Meyrick, 1932 as type species, and characterized by Gozmány and Vári (1973) by the ligulate “subscaphium” and the “two circular, strongly sclerotized lobes” on the caudo-lateral angle of the ring. However, the usage of these terms for the male genitalia seems to be confused and the systematic position of Dinica at the subfamily level is disputable. Seven nominal species have been subsequently included in this genus, five from the Ethiopian Region (Meyrick, 1932, 1934; Gozmány and Vári, 1973; Robinson, 2001; Gozmány, 2004) and two A complete list of available Memoirs can be found at www.acnatsci.org/hosted/aes/memoirs.html from Japan and Nepal (Meyrick, 1935; Moriuti, 1982; Petersen, 1983). Until now, no species of Dinica have been reported from China.

Later, Gozmány and Vári (1973) used Male genitalia (Fig. 3). Uncus trianglar with apex narrow and pointed, weakly “subscaphium” and regarded the “two circular, strongly sclerotized lobes” as the sclerotized. Subscaphium very large and well sclerotized, posterior half rhom- true gnathos. Sakai (2002) reported the “lobes” as gnathos from D. endochrysa boidal with dorsally curved apex, equal in length to valva. Tegumen and vinculum based on the small membranous connection area, which is absent in the other fused into a ring with two strongly sclerotized lobes at caudo-lateral angles. Juxta Oriental species, present between the “lobes” and tegumen. Gozmány (2004) elongate shield-like, dorsal base emarginated at middle. Saccus slender, equal in also regarded the latter as a part of the gnathos, without referring to the “sub- length to lateral part of ring. Valva broad, ventrally with a distinct pollex at middle; inner side with dense stout bristles in posterior half. Aedeagus slender, nearly scaphium.” In this paper, we use “subscaphium,” as defined by Tuxen (1970), as straight, slightly curved ventrally; cornutus absent. a “sclerotization of ventral part of tuba analis and sometimes fused with caudal part of gnathos.” Even when the subscaphium and gnathos are fused, then the “two caudo-lateral, strongly sclerotized lobes” cannot be a part of the gnathos but part of the ring (tegumen). This is supported by the observation that the proximal part of the “subscaphium” is separated from the “lobes” by a membranous area in the new species. Measurements in millimeters were made using a binocular microscope. Dinica rhombata Huang, Wang and Hirowatari, NEW SPECIES (Figs 1-3) Diagnosis: This new species is very similar to D. endochrysa in appearance but differs considerably from the latter in the following features of the male genitalia: Uncus triangular; subscaphium larger and well sclerotized; juxta wedge- shaped; saccus slender; aedeagus straighter. Description of the male: Wingspan 13.6-13.9 mm, forewing length 6.3-6.4 mm, antenna length nearly 4.0 mm (Fig. 1). Head. Vertex covered with dense, erect, snow-white scales. Antenna filiform Fig. 1. Dinica rhombata sp. nov. Holotype, male. and smooth, about 0.65 the length of forewing; scape smooth scaled. Frons bearing long, brownish gray hairs. Maxillary palpus 5-segmented, sparsely clothed with pale gold scales. Labial palpus covered with short creamy scales but dark brown ventrally. Thorax. Dorsum smooth with dense snow-white scales; tegula snow-white with black scales at basal 1/3. Fore- and midlegs extensively covered with dark brown scales; hind legs covered with pale brown scales; hind tibia bearing dense long, pale brown hairs.

Hindwing relatively broad, 2.1-2.3x as long as wide including fringes, 3.2-3.4x as long, as wide excluding fringes; ground color brownish gray, semihyaline with long pale brown fringes except basal 1/2 of costa; venation (Fig. 2), M1 and M2 stalked, M1 terminating near apex of costa. Abdomen. Dorsum gray, heavily irrorated with brown to fuscous-tipped scales; venter mostly white with grayish irroration; abdominal segment VIII with dense slender white scales covering genitalia.
