Li, Xiao-Ming & Liu, Guo-Qing, 2006, A study on genus Chlamydatus Curtis, 1833 from China (Heteroptera: Miridae: Phylinae), Zootaxa 1271, pp. 57-68 : 60

Chlamydatus laminatus sp. nov.

( Figs. 1–2 , 9 , 13 , 18–20 )

Type specimens: Holotype: male, CHINA: Xiaojin County (30°59'N, 102°21'E), Sichuan Province, alt. 2350m, 26.viii.1963, Le­yi Zheng leg.. Paratypes: 3 males, 6 females, same data as holotype.

Diagnosis: Recognized by the small size, total length 2.32–2.81, the ovoid shape, the dark coloration of body, the yellow femora with dark spots, and the form of male genitalia. Most similar to C. pullus in size and coloration of dorsum, but distinguished by the structure of phallotheca and the coloration of femora. The new species has a lobelike projection on the dorsum of the phallotheca ( Fig.19 ), whereas the phallotheca of C. pullus is without a lobelike projection ( Fig.25 ); the femoral coloration is also different ( Figs.13, 16 ).

Description: Male ( Fig. 1 ): Macropterous, elongately oval.

Coloration: Dorsum black; eye brown with margin pale; antennae unicolorous black, covered with dark hairs; clypeus black; buccula yellow, with pale long setae; labium deep brown; exposed part of mesoscutum black; membrane of wing fumose, without any spots; coxae dark; femora pale brown, with dark spots ( Fig. 13 ); tibiae pale brown; tibial spines black, with distinct black bases; tarsal segment III and claw blackish brown; body beneath blackish brown.

Structure: Dorsum smooth, weakly shining, covered with recumbent, pale, simple setae; antennal segment I with 2 blackish brown setae at the middle; anterolateral angles of pronotum with a long erect spine; abdominal venter with shining, recumbent hairs; head almost vertical; clypeus nearly obscured from above; vertex broad, relatively flat in dorsal view, posterior margin of vertex straight; eyes more or less conforming to anterior margin of pronotum, occupying almost total height of head in lateral view; dorsal margin of antennal fossa at level of ventral margin of eye; total segments III and IV longer than length of segment II; labium reaching to about posterior margin of middle trochanters; hemelytra nearly parallel­sided, corial margin slightly convex, hemelytra weakly deflexed at fracture; membrane relatively developed; metathoracic scent­gland evaporatory area as in Fig. 9 .

Male genitalia ( Figs. 18–20 ): Vesica relatively small with a short apical attenuation, secondary gonopore well sclerotized, situated near apex of vesica; left paramere boatshaped; right paramere lanceolate; phallotheca distinctive from other species of this genus, with a lobelike projection dorsally.

Female ( Fig. 2 ): The coloration and surface are similar to male. But the size smaller than male, body broader, hemelytra more convexly rounded.

Distribution: China (Sichuan).

Etymology: Named for the dorsal lobelike projection of the phallotheca.
