Further records and descriptions of the plant bug subfamily Phylinae (Hemiptera: Heteroptera: Miridae) from Thailand Author Yasunaga, Tomohide Author Duwal, Ram Keshari text Zootaxa 2015 3981 2 193 219 journal article 10.11646/zootaxa.3981.2.3 4a0a6277-0d8f-4ccd-9226-03ed43e614db 1175-5326 253581 F3001721-E0FC-46CA-AA16-3905C4D42BFE Campylomma nanna n. sp. ( Figs. 5 E, 8, 10−12) Diagnosis. Readily recognized by its noticeably tiny size (most individuals less than 2.0 mm in total length: Fig. 5 E); narrow head ( Fig. 8 ); simple form of the endosoma ( Fig. 10−11 ); and comparatively large, rounded female sclerotized rings that are relatively contiguous to each other ( Fig. 12 ). The tiny size and unique form of the genitalia enable to distinguish this new species from other related congeners. Description. Body generally pale green, elongate ovoid, tiny, usually less than 2.0 mm in total length; dorsal surface shining, with rather densely distributed, simple, brown, semierect setae. Head narrow, 0.5 mm in width across eyes. Antenna pale brown, not much sexually dimorphic in coloration and thickness; segment II with a narrow, obscure ring at base. Labium pale brown, short, not much exceeding apex of mesocoxa; apical half of segment IV shiny brown. Hemelytron somewhat semitransparent, or tinged with white; membrane pale grayish brown. Ventral dark spots on metafemur small. Male genitalia ( Figs. 10−11 ): Endosoma weakly sigmoid, tapered apically, with a sclerotized edge broadened subapically. Female genitalia ( Fig. 12 ): Bursa copulatrix narrow; sclerotized rings comparatively large, rounded, rather contiguous to each other. Measurements (♂/♀): Total body length 1.8−1.9/ 1.9−2.1; length from apex of clypeus to cuneal fracture 1.19−1.28/ 1.29−1.33; width of head across eyes 0.50−0.51/ 0.49−0.51; width of vertex 0.23−0.24/ 0.24−0.26; lengths of antennal segments I-IV 0.10−0.12, 0.40−0.46, 0.24−0.27, 0.19−0.22/ 0.11−0.13, 0.40−0.42, 0.24−0.30, 0.22−0.24; mesal length of pronotum 0.26−0.29/ 0.27−0.29; basal width of pronotum 0.70−0.72/ 0.68−0.72; maximum width across hemelytron 0.81−0.84/ 0.84−0.87; and lengths of metafemur, tibia and tarsus 0.60−0.64, 0.85−0.87, 0.25−0.27/ 0.61−0.63, 0.84−0.92, 0.26−0.30. Etymology. From Greek, nannos (= dwarf), referring to the tiny size of this new species. Biology. This new species was found from Leucaena sp. ( Fabaceae ), together with C. lividicornis . Collection records suggest that this phyline has at least two generations per year.
