Zorotypus magnicaudelli Mashimo, Engel, Dallai, Beutel & Machida , sp. n. ( Fig. 6 View FIGURE 6 )

Type series. Holotype, apteron male, MALAYSIA: Cameron Highland, Gunung Brinchang (elevation ca. 1,800 m), 13 April 2011, coll. Y. Mashimo & R. Machida (UKM). Paratypes, 7 apteron males, 6 apteron females, 1 alate female, 1 deälate male, same data as holotype (UKM, SMRC, SEHU). Apteron and alate specimens were collected under the bark of rotting wood.

Diagnosis. This species closely resembles Z. caudelli but can be distinguished from that species by the following features: body size approximately 1.5 times larger; six to eight long, stout bristles on ventral surface of metafemur vs. only four in Z. caudelli ( Figs. 5 View FIGURE 5 D, 6D); and basal plate of male genitalia much more robust than in Z. caudelli (cf. Figs. 5 View FIGURE 5 E, 6E).

Etymology. The specific epithet is combination of the Latin term magnus (meaning, “great”) and caudelli , and is a reference to its larger relative size.

Genitalia symmetrical ( Fig. 6 View FIGURE 6 E); basal plate well sclerotized, with broad, robust, anterior tongue-like process, and posteriorly bifurcated; with long, sclerotized, coiled flagellum; aedeagus hooked ( Fig. 6 View FIGURE 6 E).

Apteron female. General features as in male except as follows: Abdominal T10 not posteromedially incised, with three or four moderate-length setae on each side of midline; T11 uniformly sclerotized, not divided into halves (i.e., not divided into hemitergites), with small setae and a pair of moderate-length setae; S2 well sclerotized with a pair of small setae; S3 with a single transverse row of six short or moderately long setae on each side of midline; S8 extensive, sparsely covered with moderate-length setae, posteromedially with round membranous region; S9 short trapezoidal; bifurcated basad projection present extending beneath S8, several small setae and two pairs of moderate-length setae along posterior margin.

Zorotypus sp. MY2: Yoshizawa & Johnson, 2005: 579. Zorotypus .328: Yoshizawa, 2010: Supplementary data.

Type series. Holotype, apteron male, MALAYSIA: Pahang, Endau, 9 July 2003, coll. K. Yoshizawa (UKM). Paratypes, 8 apteron males, 11 apteron females, same data as holotype (UKM, SEHU, SMRC).

Diagnosis. This species resembles Z. caudelli and Z. magnicaudelli but can be distinguished from both by the following features: paler body color, six long stout bristles on ventral surface of metafemur (versus different number in the other two species); antler-shaped basal plate of male genitalia; female anteromedian projection of S9 not bifurcated.
