GALEATUS-GROUP FROM CHINA (HEMIPTERA, TINGIDAE)

Galeatus -group(=“Galeatus-Hyalochi-ton”genera-group of Pericart, 1983)includes 4 genera of Tingidae in China, ie. Aconchus Horvath, Dulinius Distant, Galeatus Curtis and Habrochila Horvath. In this paper, 10 species of Galeatus-group are dealt with, including one new species, Galeatus trevius Li, sp. nov. and 9 known species. The diagnostic characters, research history and classification background of each genus are summarized respectively. The specimens examined, host plants and distributions of each species are recorded in detail. Key to species of Galeatus Curtis in China and 8 morphological figures are presented.1 Aconchus Horvath, 1905 (Figs.1-6)Metathoracic scent gland ostiole absent. Female reproductive organ: subgenital plate absent; vagina with a sclerotized ring at base, and extending proximad into a broad membraneous sac from which a pair of lateral oviducts arise; lacking pseudosper-mathecae (Fig.2). Pygophore with a pair of processes in venter (Fig.1). Remarks. Drake and Davis (1960) concluded that pseudospermathecae are present in Tinginae but absent in Cantacaderinae, and Lis (1999) partly agreed on this conclusions with an argument that Phatnomatini of Cantacaderinae having pseudospermathecae as well. Aconchus Horvath is a typical member of Tinginae but without pseudospermathecae. This showes that the distribution pattern of pseudospermathecae in family Tingidae is still open to be studied.Aconchus urbanus(Horvath, 1905)Distribution.

Discoidal area of hemelytron almost flat only with slight raised at apex6 6 Body longer (3.20-4.80mm), hemelytra strongly surpassing abdominal apex. Occipital spines longer than 2 times of height of hood. Cells on lateral carinae absence of fined granules. The cyst in triangular pronotal process narrowG. spinifrons (Fallen, 1807)Body shorter (2.6-3.8mm), hemelytra slightly surpassing abdominal apex. Occipital spines shorter than 2 times of height of hood. Cells on lateral carinae with fined granules.

In the work of Jing (1981), the species was confused with Galeatus spinifrons(Fallen, 1807). We check a great number of specimens and vertify its distribution in the mainland of China.

Galeatus trevius Li, sp. nov. (Figs.7-8)Description. Macropterous. Head dark, 5 cephalic spines long, brownish fuscous. Antennal segment Ⅲ 3 times of Ⅳ in length, the latter clothed with long hairs at apex. Pronotum tricarinate, lateral carinae sinuate, laminate, uniseriate with 3 large areolae. Median carina slightly higher than hood, arched, uniseriate with 4 large cells, apical cell and area beside first cross-vein fuscous, basal 3 cells clothed densely with long hairs but apical cell smooth. Hood laterally enflatted, highly raised, extending over apex of head, biseriate with 3 cells in upper row and 2-3 cells in lower row, cells in upper row smooth, fuscous, cells in lower row transparent and covered densely with long hairs. Paranota smooth, without color marking, uniseriate with 5 cells. Triangular pronotal process flatted and covered with small areolae at base but inflated (sac-like) with large cells at apical half. Pronotal disc moderately convex, testaceous and densely punctuate.Hemelytra with outer margin abruptly widened at base (nearly right-angle). Costal area uniseriate, the areolae fairly large and clear; subcostal area uniseriate at basal half part and triseriate at apex half; discoidal area uniseriate, 3 large cells in total; sutural area biseriate. Meansurements (mm). ♀:body length 4.30, width(across base of hemelytron)2.52. Antennal segments length Ⅲ∶Ⅳ=0.9∶0.30. Length of median carina 1.43, hood 0.97, hemelytron 2.85 and discoidal area 1.26.Holotype ♀, Yuli County (alt. 1000 - 1030m ), Xinjiang Weiwuerzu Automatic Region, China, 15 July 1958,LI Chang-Qing leg. Deposited in the Institute of Zoology, Chinese Academy of Sciences, Beijing, China (IZAS).Remarks. Among the 15 recorded species of Galeatus in the world, only 6 species have laminate lateral carinae; of the 6 species, inermis is unique by absence of cephalic spines, straight lateral carinae, gradually widened outer margin of hemelytron at base and smooth body. G. scrophicus Saunder, G. sinuatus (Herrich-Schaeffer) and G. regius Golub all have sinuate lateral carinae and uniseriate costal area just like the new species, but scrophicus and regius are characterized by sphere-like hood which is higher than the median carina, and sinuatus with elongate body, uniseriate hood and 2 areolae of lateral carinae. The new species is similar to G. cellularis Jakovlev and G. vitreus Golub with laterally enflatted and biseriate hood, abruptly widened outer margin of hemelytron, sinuate lateral carinae, but the latter 2 species having 2-3 rows of areolae in costal area of hemelytron.Etymology. The specific name comes from the letter rearrangement of Galeatus vitreus, which is allied to the new species.Galeatus scitulus Drake and Maa, 1953Distribution. China (Fujian).Galeatus clara Drake, 1948Distribution. China (Shanghai).4 Habrochila Horvath, 1912Habrochila chinensis Drake, 1947 Distribution. China (Meitonghsein).
