Measurements (in mm). ♁/ ♀: Total length of body 3.20– 3.65 / 3.50–4.10; head width including eyes 0.96 / 1.02; vertex width 0.28–0.29 / 0.37–0.38; lengths of antennal segments I–IV 0.48, 1.77, 0.90, 0.48 / 0.47, 1.55, 0.90, 0.54; labial length 1.38 / 1.50; mesal length of pronotum including collar 0.77 / 0.90; basal width of pronotum 1.35 / 1.62; maximum width across hemelytron 1.50 / 1.80; and lengths of metafemur, tibia and tarsus 1.58, 2.28, 0.57 / 1.73, 2.40, 0.53.

Differential diagnosis. Recognized by moderate size (3.2–4.1 mm); pale green general colouration, usually with reddish fasciae on hemelytron ( Figs 78–79 View Figs 73–82 , but hemelytron sometimes widely pale as in Figs 63 View Figs 54–65 , 66 View Figs 66–72 ); reddish brown metafemur ( Fig. 56 View Figs 54–65 ); developed pygophoral spine ( Fig. 126 View Figs 118–135 ); elongate, not bifurcate hypophysis of left paramere; and long hair-like spinules on endosoma ( Fig. 128 View Figs 118–135 ). Distinguished readily from the preceding A. alaneylesi   sp. nov. by significantly larger size and reddish metafemur.

Biology. This polyphagous mirid is associated with inflorescences of various dicots, such as Amaranthaceae   , Anacardiaceae   , Araliaceae   , Asteraceae   , Euphorbiaceae   , Fabaceae   , Fagaceae   , Oleaceae   , Rutaceae   and Sabiaceae ( YASUNAGA 2001)   ; the immature forms were also confirmed on Rhus javanica   L. ( Simaroubaceae   ), Mallotus   spp. ( Euphorbiaceae   ), Meliosma arnottiana (Wight) Walp.   ( Sabiaceae   ), Zanthoxylum ailanthoides Siebold & Zucc.   ( Rutaceae   ). Some individuals were found to feed on crops, cucumber, eggplant, mango or papaya.A multivoltine cycle is assumed for Anthophilolygus bakeri   ; in subtropics and tropics, the adults are collected almost throughout a year. The adults are frequently attracted to UV lights, and occasionally hundreds of individuals were observed to visit light trap screens at night. Both adults and immature forms of Anthophilolygus bakeri   comb. nov. are found dominantly on inflorescences of various dicots, evergreen broadleaf trees in particular; this taxon does not appear to be host plant specific, presumably utilizing pollen and/or honey dew as a major diet component. Distribution. Japan (Kyushu, Bonin Islands, Ryukyus) ( YASUNAGA & TAKAI 2014), Taiwan (almost whole country except for central highlands) ( POPPIUS 1915 and present records), Philippines (Luzon, Negros, Visayas) ( POPPIUS 1915; new record for Visayas), Cambodia (Siem Reap) (new record), Laos (Vientiane) (new record), Thailand (Chaiyaphum, Chiang Mai, Nakhon Nayok, Nakhon Ratchasima) (new records).

This widespread mirid has presumably been introduced to some Japanese subtropical islands ( YASUNAGA 2001), and is recently expanding its distribution northward in Japan, probably due to the global warming ( YASUNAGA & TAKAI 2014).

Comments. Colouration is variable (reddish pattern on dorsum in particular). There are a few more unidentified congeners (with darker and larger dorsal maculae) in the Oriental Region (cf. Fig. 81 View Figs 73–82 ); A. bakeri   is generally paler than those mirids, with smaller dorsal maculae or fasciae.

POPPIUS (1915) described Lygus tainanensis   [later transferred to Prolygus   by SCHWARTZ & KERZHNER (1997)] from Taiwan, comparing it only with L. matsumurae Poppius, 1915   [placed in Neolygus   by LU & ZHENG (1998b)]. POPPIUS (1915) did not mention its similarity to Lygus bakeri   , although pale female specimens of L. bakeri   ( Figs 58 View Figs 54–65 , 66 View Figs 66–72 right) are nearly impossible to be distinguished from L. tainanensis   ( Fig. 67 View Figs 66–72 ). Based on the great similarity in habitus and female genitalia (cf. SCHWARTZ & KERZHNER 1997: Figs 33–34 View Figs 33–42 ), both species are regarded to be conspecific, and what was described as L. tainanensis   is apparently a pale variant of L. bakeri   , one of the most common mirids in Taiwan.Accordingly, a new synonymy is proposed: Anthophilolygus bakeri ( Poppius, 1915)   = Prolygus tainanensis ( Poppius, 1915)   , syn. nov.

Both specific names were published simultaneously by POPPIUS (1915) and have been impartially treated by subsequent authors in 20th century ( CARVALHO 1959, 1980; SCHUH 1995; SCHWARTZ & KERZHNER 1997; KERZHNER & JOSIFOV 1999). We presently select L. bakeri   as valid name.
