Arcofuzia Wei, Shih et Ren, gen. nov.
Genus Arcofuzia Wei, Shih et Ren gen. nov. Type species: Arcofuzia cana Wei, Shih et Ren sp. nov. Differential diagnosis: Forewing extremely wide, Sc thick and without branches, with many small crossveinlike reticulations that are more distinct than in Fuzia; wing venation rich (43 to 54 veins at margin), more than average venation in Fuzia; intercalary veins thick, distinct all over wing surface; anal field with distinct diagonal kink; with distinctly cambered markings located near the apex of forewings from anterior of R to the anterior of CuA, forming a crescent. Etymology: Arcofuzia is a combination of arco- (Latin for cambered), referring to its cambered markings near the apex of forewings, and the type genus name ‘ Fuzia ’; gender feminine. Remarks: The new genus differs from Parvifuzia Guo & Ren, 2011 in having larger body size and rich forewing venation. The new genus can be distinguished from Fuzia Vršanský, Liang & Ren, 2009 by forewing markings, thick Sc, many small but very distinct crossvein-like reticulations, and diagonal kink in the anal field. The new genus is similar to Colorifuzia Wei, Liang & Ren (in press) in body size, rich forewing venation and forewing markings, but differs mainly by the shape of the markings, the anal field diagonal kink, presence of numerous small crossvein-like reticulations and thick, unbranched forewing Sc.Published as part of Wei, Dandan, Shih, Chungkun & Ren, Dong, 2012, Arcofuzia cana gen. et sp. n.

Jurahylobittacus astictus Li & Ren & Shih 2008
Jurahylobittacus astictus sp nov. (Figs 2A–E, 3C–D) Etymology. This species is named astictus after having no maculae on wings. Material. Holotype CNU-M-NN2007002-1 and CNU-M-NN2007002-2, positive and negative (coll. Shih Chungkun), deposited at the Key Lab of Insect Evolution & Environmental Changes, the College of Life Sciences, Capital Normal University (CNU), Beijing, China. Horizon and locality. Jiulongshan Formation, Middle Jurassic, Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia, China. Diagnosis. Sc-r at about as long as its length before end of Sc; no cross-vein between R 2 and R 1; and no maculae on wings. Description. Lateral view of a complete insect. Rostrum slender; abdomen long and slender, slightly beyond wing tip (Fig. 2 A-C). Wings. Basal part of forewing narrow; gradually broadening from base towards rounded apex; pterostigma slightly dark; sc-r is close to the tip of Sc; M 1+2 dividing far beyond R 4+5; one cross-vein between R 2+3 and R 4; two cross-veins R 4 and R 5; two cross-veins between R 5 and M 1; two cross-veins between M 1 and M 2; two cross-veins between M 2 and M 3; one cross-vein between M 3 and M 4; two cross-veins between CuA and CuP; two cross-veins connecting 1A and 2A; 2A extending almost to level of origin of M; and vein 3A absent (Fig. 2D). Hindwings seem to be identical to the forewings in the venation, but their Sc short, ending distally before the fork of Rs ( Fig. 2E). Abdomen. At least nine visible segments in lateral view (Fig. 2C). Terminal abdominal segments were well preserved, basistyles, aedeagus, cercus and epiandrial lobe visible (Fig. 3 C-D). Body 18 mm long, forewing 12.6 mm long, 3.0 mm wide; hind wing 10.3 mm long, 3.0 mm wide.Published as part of Li, Yan-Li, Ren, Dong & Shih, Chung-Kun, 2008, Two Middle Jurassic hanging-flies (Insecta: Mecoptera: Bittacidae) from Northeast China, pp. 38-46 in Zootaxa 1929 (1) on pages 43-45, DOI: 10.11646/zootaxa.1929.1.2, http://zenodo.org/record/523080

Abrotoxyela Gao, Ren & Shih, 2009, gen. nov.
Genus Abrotoxyela gen. nov. Type species: Abrotoxyela lepida sp. nov. Diagnosis: Forewing with Sc triple-branched and the first branch intersecting with C nearly 1 / 4 of the length; Sc terminating at C distal to the origin of Rs; Sc 2 short, inclining toward basal of wings, intersecting R before the origin of Rs; basal section of Rs approximately as long as that of M. Eyes extraordinarily large and the third segment of antenna 2.5 times as long as the rest flagellomeres. Ovipositor short. Etymology: The generic name is a combination of Greek prefix abrot- referring to the pretty and gorgeous species included in this genus, and ‘ xyela ’, the name of one of the genera included in Xyelidae. The gender is feminine. Species included: The type species and A. multiciliata sp. nov. Comparison: More than 20 genera of this subfamily have been reported up to date (Abe & Smith, 1991; Rasnitsyn, 1993; Zhang & Zhang, 2000), and 9 of them have been recorded in China (Zhang & Zhang, 2000; Gao & Ren, 2008). Rasnitsyn compiled a detailed key to the known genera of this family (Rasnitsyn, 1969) and a key to the known taxa of subfamily Macroxyelinae in Northeastern China was given by Zhang Haichun and Zhang Junfeng (Zhang & Zhang, 2000). Abrotoxyela can be assigned to the subfamily Macroxyelinae based on its complex venation, very long 3 rd segment of antennae (nearly 2.5 times as remained flagellomeres), and short ovipositor. Within this subfamily, the new genus is similar to Xyelites Rasnitsyn, 1966, in forewing with Sc triple-branched and pterostigma fully sclerotized, but the new genus can be differentiated from Xyelites by the following characters: Sc terminates at C distal to the origin of Rs and length of basal section of Rs approximately equals that of M. The triple-branched vein Sc is a unique character which distinctly differentiates Abrotoxyela from other Xyelidae.Published as part of Gao, Taiping, Ren, Dong & Shih, Chungkun, 2009, Abrotoxyela gen. nov. (Insecta, Hymenoptera, Xyelidae) from the Middle Jurassic of Inner Mongolia, China, pp. 52-59 in Zootaxa 2094 on page 53, DOI: 10.5281/zenodo.18756

Similsciophila Shi & Shih & Ren 2014, gen. nov.
Similsciophila gen. nov. Type species: Similsciophila singularis sp. nov. Species included: Similsciophila singularis sp. nov. and Similsciophila sinuata sp. nov. Diagnosis Body medium-sized, covered with long and dense pubescence. Mesonotum convex. Scutellum sharp and clearly projecting. Forewing Sc elongate, shorter than one-half of wing length; sc-r situated distinctly basal to Rs origin, arising near midway between h to Sc ending at margin; cell r distinctly large, longer than one-sixth of wing length; Rs furcated distad to fork of M 1+2; bRs longer than r-m; R 1 slightly curved; both R 1 and R 4+5 divergent terminally; R 4+5 arched near its mid-length; stem of M not developed and thin; M 1+2 furcated slightly distad to level of Sc ending. Tibiae and tarsi with short sparse setae. Etymology The generic name is derived from the Latin (simil -), in reference to similar, and sciophila is from the generic name Mesosciophila. Remarks Based on the venation, Similsciophila gen. nov. is distinguished from Mesosciophilopsis Blagoderov, 1993 and Jurasciophila Li and Ren, 2009 by the following characters: wing longer and wider; cell r distinctly larger, and longer than one-sixth of wing length. The new genus is similar to the genus Paramesosciophilodes Zhang, 2007, but differs mainly by bRs longer than r-m. It also differs from Mesosciophilina Kovalev, 1985, Mesosciophilodes Rohdendorf, 1946 and Mesosciophila Rohdendorf, 1946 in that R 4+5 arched near its mid-length. Distribution China.

A new macrolepidopteran moth (Insecta, Lepidoptera, Geometridae) in Miocene Dominican amber
A new genus and species of fossil moth, Miogeometrida chunjenshihi Zhang, Shih & Shih, gen. et sp. nov., assigned to Geometridae, is described from Miocene Dominican amber dating from 15–20 Mya. The new genus is characterized by the forewing without a fovea, R1 not anastomosing with Sc, no areole formed by veins R1 and Rs, R1 and Rs1 completely coincident, M2 arising midway between M1 and M3, anal veins 1A and 2A fused for their entire lengths; and the hind wing with Rs running close to Sc + R1 and M2 absent
