Diagnosis

Dicyphus josifovi is recognized by the following combination of characters: macropters only. Body length 4.35– 4.51 mm in males and 4.56–4.90 mm in females; body mostly pale with dark-brown markings on head and thoracic pleura ( Fig. 2); collar and pronotal disk whitish to whitish stramineous, contrasting with brown callosite region; mesoscutum mostly orange; AI elongate, mostly red; AII mostly stramineous, with apical 1/3rd brown; AII>1.5× longer than pronotum width in males; pronotal callosite region 1.35–1.57× longer than disk in males, 1.31–1.71× in females; left paramere narrow and short apophysis, weakly expanded distally ( Fig. 10C–D); aedeagus with two endosomal lobes, each lobe with moderately long, weakly arcuate lobal sclerites ( Fig. 14B).

Redescription

Males.

Coloration: Dorsum mostly stramineous with orange and dark-brown markings, sometimes with red highlighting ( Fig. 2). Head: mostly stramineous to whitish, with contrasting markings; frons+vertex with a moderately long X-shaped dark reddish brown marking extending to level of posterior margin of eyes; clypeus dark-brown; mandibular plates stramineous; maxillary plate with faint embrownment; vertex orangish yellow; postocular margins of head dark brown, extending to genae; gula and bucculae stramineous. Antennae: fuscous; AI mostly red, with subbasal narrow dark reddish brown annulation, base and apices stramineous to whitish dark-brown on the base; AII medially pale, with basal and distal 1/3 rd dark brown; AIII and AIV concolorous, uniformly dark brown, mostly with base of AIII narrowly stramineous. Pronotum: collar and pronotal disk whitish to whitish stramineous, translucent; callosite region mostly brown, rarely darker posterolaterally; humeral angles weakly embrowned. Thoracic pleura and sterna: propleuron mostly shiny dark brown with ventral margin stramineous; mesobasisternum broadly shiny dark brown; mesepimeron and metepisternum including evaporative areas stramineous, sometimes with peritreme dark brown. Mesoscutum: mostly orange, with faint embrownment. Scutellum : lateral angles broadly pale stramineous to whitish with narrow brown stripe along midline. Hemelytra : translucent, mostly stramineous with medium-brown to reddish brown markings/highlighting; with three pairs of medium-brown to reddish brown markings, each pair at corial fracture, apex of endocorium and tip of cuneus, latter more reddish; membrane veins embrowned to reddish. Abdomen: venter mostly stramineous, pygophore sometimes with brown markings.

Structure: Head: interocular distance 1.05–1.24× greater than eye width. Antennae: AI long, 1.99–2.23× longer than interocular distance; AII 1.50–1.62× longer than posterior width of pronotum. Pronotum: disk 1.35–1.57× longer than callosite region. Male genitalia: left paramere apophysis narrow and short, with shaft weakly arcuate, apex narrowly expanded ( Fig 10C–D); aedeagus with two endosomal lobes, each lobe with moderately long endosomal lobal sclerites; lobal sclerites subequal in size, near symmetrical and weakly arcuate ( Fig. 14B).

Females. Coloration, vestiture, texture and structure mostly as in males. Head: interocular distance 1.11–1.26× longer than eye width. Antennae: AI 1.47– 1.82× longer than interocular distance. AII 1.02–1.20× longer than posterior pronotal width. Pronotum: disk 1.31–1.71× longer than callosite region. Abdomen: venter pale yellowish green.
