Redescription.
Coloration. Body mostly ochraceous with fuscous and dark brownish decoration. Head: vertex with irregular median, longitudinal band extending from base of head to apex of clypeus; eyes and ocelli reddish; antenniferous tubercles and surroundings irregularly suffused with dark brown; antennomere I with brownish longitudinal line laterally, apex fuscous; antennomeres II–IV fuscous to dark brownish with base and apex with slightly and finely ochraceous; labial trough margined with dark brown; labiomere I ochraceous with base and apex fuscous; labiomeres II–IV pale fuscous. Thorax: punctation brownish; pronotum with irregular brownish bands along lateral margins and medially; median band interrupted with longitudinal ochraceous line posterior to pronotal callosities; a rounded, dark brownish spot at each humeral angle; scutellum pale fuscous except ochraceous trifurcate carina interrupted by irregular brownish spot medially. Clavus and corium of mesothoracic wings semi-hyaline, ochraceous; punctation dark fuscous; corium with irregular fuscous spots of various extent medially and apically; costal margin margined with dark brownish; membrane with fuscous venation. Thoracic pleurites with irregular dark brownish band longitudinally extending to abdominal connexiva; rounded dark brownish spots at each supracoxal lobe; peritreme of MTSEA ochraceous. Legs ochraceous, apices of femora and tibiae suffused with brown.Abdominal dorsum ochraceous with irregular brownish spot at segment VII above genital capsule of male; abdominal connexiva with band described above for thoracic pleurites; venter with irregular reddish spots at base of segments; tubercles of male pygophore blackish.

Details of
Apennocoris pilosulus
, macropterous male: A. labial trough, B. metapleurite with structures of metathoracic scent efferent apparatus (indicated with red arrow), C. detail of thorax and abdomen in lateral view with dorsal setosity. (scale bar: 1 mm).
Structure (only characters not mentioned in generic description are provided). Body moderately elongate, covered with silvery, semi-erect pubescence shorter than dark bristles. Ratio of eye-ocellus distance to distance of ocelli: 1: 0.54. Ratio of antennal segments: 1: 2.86: 2.38: 2.14. Ratio of labial segments: 1: 0.45: 0.80: 0.80. Pronotum ratio (basal width to median length): 1: 0.63. Trifurcate carina of scutellum well-developed, somewhat bulging. Scutellum ratio (basal width to median): 1: 0.97. Length of claval commissure to median length of scutellum: 1: 2.44. Abdominal connexiva with sparse semi-erect pubescence.
Measurements
(in mm). Total body length: 4.20; head length: 0.78; head width: 1.47; distance of ocelli: 0.32; pronotum length 0.85; pronotum width 1.36; scutellum length 0.75; scutellum width: 0.76; length of claval commissure: 0.31.
Diagnosis.
Superficially resembles the New Caledonian
Germalus scutellatus
(Distant, 1920)
in coloration and pattern, however, structural characters provided in the generic redescription allow an easy separation of the two species.
