Taiwan . Type Material. Holotype ( ♂ ): Mt. Nanfengshan , 1000 m , Nr. Liukuei Kaohsiung Pref. TAIWAN , 21-III-1981 T . Shimomura leg. ( EUMJ ) [left antenna, genitalia, pygidium, and abdominal segments VII–X mounted in glycerin microvial and placed under the specimen; abdominal segment X incomplete; dorsal and ventral patterns incomplete (= mainly central part of elytra under scutellum and central part of metasternum)] . Paratypes . 2 specimens : 1 ex. ♀ , Lishan Taichung Hsien Taiwan 22.VI.1976 H. Makihara leg. ( EUMJ ) ; 1 ex. ♀ , Liu Kui , Kao Hsiung Hsien S-Taiwan 19.II.1987 col. K. Baba ( EUMJ ) [dorsal pronotal pattern (left part) and dorsal elytral patterns (central part) incomplete, fore legs without tarsi, apex of left elytron broken] . Etymology. The epithet “ taiwanicus ” is derived from the country where the species was discovered – Taiwan . Diagnosis. This new species resembles A. nepalensis from Nepal . However, it can easily be distinguished from that species by the following unique combination of characteristics: 1) Elytral patterns of A. taiwanicus are created by yellowish, light and dark brown scales, mixed yellowish and light brown scales forming irregular patterns, among them dark brown scales present ( Fig. 1 ), whereas in A. nepalensis the elytra are covered largely by white and dark brown scales and some tan, light brown scales, white and light brown scales forming five transverse bands of variable width and shape; 2) Abdominal ventrites of A. taiwanicus have small patches of dark brown scales on the lateral margins of ventrites II–V, whereas in A. nepalensis the dark brown scales cover the posterior margins of ventrites I–V. Anthrenus taiwanicus can be distinguished from other known Taiwanese species of Anthrenus by the characteristics given in the key below. Description. Holotype , male. Body convex, slightly rounded laterally; nearly 2.0X as long as wide; BL = 2.7 mm , PL = 0.55 mm , PW = 1.2 mm , BW = 1.5 mm . Head visible from above ( Fig. 1 ); eyes large, convex, oval (without internal, medial deep emargination). Median ocellus present. Frons and clypeus covered with mainly dark brown scales. Antenna with 8 antennomeres; antennal club with 2 antennomeres ( Fig. 3 ); all antennomeres brown (segments of antennal club slightly darker). Antennal club shorter than flagellum; relative length of terminal antennomere to length of penultimate antennomere nearly 2:1 (1:0.4). Antennal fossa conforming to shape of antennal club. Ratio of length of antennal fossa to length of lateral margin of pronotum 1:2.3. Dorsal and ventral surfaces dark brown, sparsely punctured, covered by subtriangular scales ( Figs. 1–2 ). Pronotum covered by mixed dark brown, light brown, and yellowish scales ( Fig. 1 ); lateroposterior declivity with yellowish scales; disc mainly with dark brown scales with light brown and yellowish scales mixed on central part of pronotum. Lateral margin of pronotum not visible from above. Scutellum small and poorly marked ( Fig. 1 ). Elytra covered by yellowish, light and dark brown scales. Mixed yellowish and light brown scales forming irregular patterns, among them dark brown scales present ( Fig. 1 ). Scales of ventral surfaces yellowish and brown ( Fig. 2 ). First abdominal ventrite without postcoxal lines ( Fig. 2 ), sulcus without scales. Lateral margins of ventrites II–V with small patches of dark brown scales. Legs brown (tibia and tarsi slightly lighter than trochanters and femora). Only trochanters and femora covered on dorsal surface with yellowish scales. Protibia without tibial spines. Tarsus with 2 curved claws. Phallus as in Fig. 4 . Parameres U-shaped, covered with setae (short mainly on lateral margins and in central area; longer setae present only on apex and inner areas of parameres). Ratio of length to width 1.5:1. Distal parts of parameres straight (not curved inward). Penis in frontal view straight ( Fig. 4 ); in lateral view, distinctly curved in basal part above apodemes and below apex ( Fig. 5 ). Pygidium brown, transverse basally, carina absent ( Fig. 7 ). Ninth abdominal segment oval ( Fig. 6 ); apex slightly elongated and rounded; setae present on dorsal and lateral margins, but only anteriorly. Figs. 1–7. Anthrenus taiwanicus , holotype. 1) Dorsal habitus; 2) Ventral habitus; 3) Left antenna; 4) Genitalia, ventral view; 5) Penis (median lobe), lateral view; 6) Abdominal segment IX; 7) Pygidium. Variability. BL = 2.55–2.70 mm , PL = 0.50– 0.55 mm , PW = 1.05–1.20 mm , BW = 1.35– 1.50 mm . In some specimens, the dorsal and ventral patterns slightly differ in color from the holotype by sometimes having whitish scales present. Distribution. Taiwan .
