Allochotes forniculatus sp. n.

(Figs 1 A–1C, 4A–4G, 6A–6B, 7A–7B)

Type series. Holotype: ♂ (TARI), “ TAIWAN: Pingtung/ Dahanshan/ VII. 18. 2007, leg. C.-F. Lee” [locality name written by Chinese character]. Paratype: 1♀ (TARI), same locality as holotype, 10. V. 2013, Y-T. Chung leg.

Type locality. Mt. Dahan-shan, Chunrih Township, Pingtung County, Taiwan.

Diagnosis. This new species is distinctly differentiated from the other Taiwanese congeners by the following characteristics: body orange; CM weakly swollen cylindrically; phallus hardly swollen; phallic plates elongate, wide.

Description. Male (n = 1, Figs 1 A–1C): Body entirely orange except for black tip of mandibles. Head, pronotum, elytra, legs, and abdomen covered with suberect yellowish orange setae.

Maxillary palpi with the last segment short, triangular, obliquely truncate at apex. Antennomeres 4 to 8 weakly serrate, gradually shortened apically; 9th and 10th serrate, as wide as long. Pronotum 1.3 times as wide as long. Elytra round, convex dorsally, 1.1 times as long as wide, widest just before middle, evenly and densely set with setigerous punctures throughout.

Pygidium (Fig. 4 A) with posterior margin almost straight. Eighth sternite (Fig. 4 B) semicircular; posterior margin almost straight. Spicular fork (Fig. 4 C) with elongate intraspicular plate; spicular lobes weakly pigmented and almost membranous; spicular apodeme 3/4 as long as the total length of spicular fork.

Aedeagus in fully inflated condition (Figs 6 A–6B) gently curved ventrally in lateral view; CM weakly swollen cylindrically; phallus hardly swollen. Tegmen (Figs 4 D–4E) with phallobase in ventral view 3/5 of the total length of tegmen, almost straight toward apical 1/3, thence weakly narrowed apically, emarginated at apex; phallobasic apodeme in ventral view elongate, dilated apically from apical 1/3, slightly sinuous in lateral view; ventral phallobasic plates weakly sclerotized; phallobasic struts divaricated from basal 1/3 of phallobase. Phallus (Figs 4 F– 4G) longer than tegmen; phallic plates in ventral view elongate, flattened, evenly dilated inwardly, with bi- or tridentate small denticles from apical 1/4 to subapices of ventral margins.

Female (n = 1): Similar to male, but the apical margin of 7th sternite roundly projected posteriorly. Pygidium (Fig. 7 A) trapezoidal; pygidial struts elongate. Eighth sternite (Fig. 7 B) with apical margin almost straight. Pronotum 1.3 times as wide as long. Elytra 1.1 times as long as wide.

Measurements. Male (n = 1): BL 6.0 mm, PL 1.6 mm, PW 2.1 mm, EW 3.5 mm, EL 4.0 mm. Female (n = 1): BL 8.1 mm, PL 2.0 mm, PW 2.6 mm, EW 4.6 mm, EL 5.1 mm.

Etymology. The specific name, meaning slightly arched in Latin, is derived from the shape of the phallus.

Distribution. Taiwan (Known only from the type locality).
