Campylomma salaciella n. sp.

(Figs. 6, 8, 10−12)

Diagnosis. Recognized by its yellowish olive green basic coloration (Fig. 6 C −D); comparatively small size; rather short labium that is reaching but not exceeding apex of mesocoxa (Fig. 8); reduced, small, dark spots of ventral metafemur; bifurcate, spinulate apical part of endosoma (Figs. 10−11); and rather small, narrow-rimmed sclerotized rings (Fig. 12), in addition to being strictly associated with a seablite, Sueada malitima growing only along coast (Fig. 6 A).

Description. Body generally yellowish olive green, elongate oval, rather small; dorsal surface shining, with uniformly distributed, simple, pale brown, semierect setae. Head somewhat narrow. Antenna pale brown; apical spot of segment I and basal ring of II often reduced in female. Labium pale brown, short, reaching but not exceeding apex of mesocoxa; apical 2/3 of segment IV dark reddish brown. Anterior half of pronotum viridescent when alive. Hemelytra widely tinged with yellow; membrane pale smoky brown, with yellow veins. Leg yellowish brown; ventral dark spots of each femur very small or reduced. Male genitalia (Figs. 10−11): Endosoma sigmoid, with bifurcate, minutely spinulate apical blades. Female genitalia (Fig. 12): Bursa copulatrix rather narrow; sclerotized rings narrow-rimmed, somewhat triangular, weakly thickened posteriad.

Measurements (♂/♀): Total body length 2.2−2.5/ 2.2−2.3; length from apex of clypeus to cuneal fracture 1.43−1.56/ 1.48−1.52; width of head across eyes 0.58−0.62/ 0.54−0.59; width of vertex 0.24−0.26/ 0.28−0.30; lengths of antennal segments I-IV 0.12−0.14, 0.60−0.62, 0.36−0.38, 0.22−0.24/ 0.12−0.14, 0.55−0.56, 0.37−0.38, 0.23−0.24; mesal length of pronotum 0.34−0.36/ 0.32−0.36; basal width of pronotum 0.74−0.77/ 0.75−0.80; maximum width across hemelytron 0.96−1.02/ 0.96−0.99; and lengths of metafemur, tibia and tarsus 0.76−0.84, 1.12−1.24, 0.35−0.37/ 0.76−0.83, 1.10−1.13, 0.33−0.36.

Etymology. From Latin, Salacia, a wife of Neptune (= a God of the sea), referring to the occurrence of this new species along northern coast of the Gulf of Siam.

Biology. This new species appears to be strictly associated with an annual seablite, Sueada malitima (L.) Dumort ( Chenopodiaceae), growing along coastal areas of the Gulf of Siam (Fig. 6 A), and was always found together with an undescribed species of the genus Melanotrichus (Orthotylinae) . Multivoltine life cycle is assumed for C. salaciella as adults and/or immatures are present almost throughout a year. The final instar nymph has greenish dorsum partly speckled with yellow (Fig. 6 F).
