( Figs. 5 View FIGURE 5 ; 6A–K)

Perreau, 1993: 343 ( Ptomaphaginus ; Type locality: CHINA, Taiwan: Fenchihu, 1409 m); Perreau, 1996: 290 ( Ptomaphaginus ; new distributional locations); Perreau, 2000: 371 ( Ptomaphaginus ; catalog); Hoshina & Sugaya, 2003: 127 ( Ptomaphaginus ; aedeagus figures).

Material examined. Paratype: CHINA, Taiwan: 1♂, Fenchihu, 1400 m, 10.V.1977, Klapperich leg. // PARATYPE, Ptomaphaginus franki M. Perreau det. 1992 // Coll. M. Perreau ( CMPR).

Redescription. Male. EBL: 2.53 mm. Length of different body parts: HL: AL: PL: ELL = 0.41: 0.78: 0.66: 1.37 mm; width: HW: EW: PW: ELW = 0.70: 0.08: 1.09: 1.11 mm. Proportion of antennomeres from base to tip in µm (length × width): 124 × 41, 107 × 47, 63 × 42, 40 × 45, 44 × 48, 30 × 54, 57 × 71, 25 × 70, 63 × 79, 61 × 78, 109 × 79.

Habitus elongated oval, relatively convex and lustreless. Moderately pigmented: mostly chestnut brown: only mouthparts, basal five antennomeres and apical half of ultimate antennomere, elytral apex, and apical part of tarsi more or less yellowish. Dorsum continually clothed with fine, recumbent and sallow pubescence. Insertions of pubescence on dorsal surfaces of head, pronotum, scutellum, elytra and femora align along transverse striolations ( Fig. 5 View FIGURE 5 ).

Head short and convex, transversely and superficially striolated, interspaces narrower than that on pronotum, HW / HL = 1.72; anterior margin round. Compound eyes normally developed, EW / HW = 0.11. Antennae slender but not very long ( Fig. 6 View FIGURE 6 A), AL / HW = 1.11; 5th slightly longer than 4th; 6th wider than long; 9th and 10th a little wider than long; 11th pear-like.

Pronotum transverse and convex ( Fig. 6 View FIGURE 6 C), widest directly before corners, PW / PL = 1.66. Sides slightly curved, narrowing from posterior to anterior; hind corners drawn out and blunt. Posterior margin with distinct postero-lateral emargination. Surface transversely striolated, SP: 46–49, interspaces narrower than that on elytra.

Elytra of medium length and weakly convex, widest directly after base, ELL / EW = 1.24. Sides feebly curved, gradually narrowing from base to apices; apices obliquely truncated ( Fig. 6 View FIGURE 6 D). Surface transversely striolated, SE: 89–92. Metathoracic wings fully developed.

Prolegs robust, with basal three protarsomeres moderately expanded ( Fig. 6 View FIGURE 6 B): TW / BTW = 1.35. Spinal arrangement on ventral side of protibia as shown in Fig. 6 View FIGURE 6 B. Profemora wider than protibiae, and carried strong and long hairs on ventral side. Mesotibiae arcuate.

Ventrite VII with two large teeth at posterior margin, and many small spines located around middle emargination ( Fig. 6 View FIGURE 6 E). Ventrite VIII with a large fossa subround and moderately shallow, almost not emarginate posteriorly ( Fig. 6 View FIGURE 6 F). Segment IX: spiculum gastrale wide, widely rounded at posterior end ( Fig. 6 View FIGURE 6 G).

Aedeagus stout and distinctly incurved around middle in dorsal view ( Fig. 6 View FIGURE 6 H): median lobe widest before base; parameres narrow, firmly attached to median lobe, strongly and sinuately curved, totally invisible before middle. Ventral operculum distinctly divided in apical part, each lobe narrowly rounded apically ( Fig. 6 View FIGURE 6 I). In lateral view, median lobe very thick and strongly bent ventrad at about apical half, apex almost not thinned, and four ventrally-oriented setae inserted below apex as well as two just before middle ( Fig. 6 View FIGURE 6 J). Internal stylus wide, multiannulate at about basal 1/3.

Female. Unexamined. Spermatheca ‘C’ shape ( Fig. 6 View FIGURE 6 K; after Perreau, 1993).

Distribution: China ( Taiwan).

Remarks. For Ptomaphaginus species from China, only this one has aedeagus distinctly incurved around middle when viewed dorsally, and parameres strongly and sinuately curved, totally invisible before middle.
