Nannogermalus marmoratus (paratype male, NHMW):A = dorsal habitus, B = lateral view Scales: A = 1 mm, B = 100 µm Colouration. Ground colour ochraceous. Head: base of vertex and surroundings of sutures fuscous as in Figures 2A, C . Eyes and ocelli translucent; back of eyestalks pale ochraceous. Antenniferous tubercles brownish. Antennomeres and labiomeres without markings. Thorax: Thoracic punctation pale fuscous. Pronotum with extended, irregular fuscous spots. Dark brownish spot near midline of pronotum, at middle of callosities and humeral angles as in Figure 2B . Scutellar callosity somewhat paler than ground colour. Clavus and corium semi-translucent, ochraceous with pale fuscous punctation. Corium with irregular fuscous spots at claval and apical margin. Thoracic pleura with extended pale brownish regions as in figure 1B. Anterior margin of mesothorax with irregular, dark brownish band. Peritreme of MTSEA pale ochraceous. Legs semi-translucent, ochraceous, indecorate. Abdomen: Abdominal tergites IV-VI with irregular, anteriorly fading brownish spots near median curvature; spots of tergite VI infused with red; base of tergite VII with an extent blackish spot medially (fig. 1D). Abdominal connexiva with extended, irregular pale brownish regions. Structure (characters not mentioned here are consonant with generic description). Body oval, covered with dense, short pubescence. Head: Ocellar distance to eye-ocellus distance: 1: 1. Ratio of antennomeres: 1: 2.3: 3.1: 3.6. Ratio of labiomeres: 1: 0.92: 0.83: 0.83. Thorax: Pronotum slightly keeled medially (fig. 2A). Pronotum ratio (basal width to medi- an length): 1: 0.6. Trifurcate carina of scutellum T-shaped, thin, widened at basal and apical edges. Scutellum ratio (basal width to median): 1: 0.7. Length of claval commissure to median length of scutellum: 1: 2.5. Abdominal connexiva with sparse semi-erect pubescence. Fig. 2. Details of Nannogermalus marmoratus (paratype male, NHMW): A = head in frontal view, B = head and pronotum, C = scutellum and hemelytron, D = abdomen. Scale: 100 µm Measurements. total body length: 2.42 (2.36-2.40); head length: 0.15 (0.14-0.15); head width: 0.90 (0.88-0.90); ocellar distance: 0.34 (0.31-0.33); antennal segments (I-IV): 0.07-0.16- 0.22-0.25 (0.05-0.07 – 0.13-0.15 – 0.20-0.21 – 0.23); labial segments (I-IV): 0.30-0.27-0.25.0.25 (0.28-0.30 – 0.25-0.26 – 0.23-0.23 – 0.22-0.23); pronotum length: 0.65 (0.64-0.66); pronotum width: 1.09 (1.07-1.10); scutellum length: 0.37 (0.35-0.37); scutellum width: 0.55 (0.54-0.55); length of claval commissure: 0.15 (0.13-15). Diagnosis. Besides the structural characters listed in generic diagnosis, the species is to be recognised by its marmorated pattern ( Fig. 2A ). Colouration may vary within an extent, but general patterns were recognizable on all studied specimens. Distribution. The specimens known to the authors were collected in along the Houadou River and Mont Mou Botanic Reserve. Etymology. The name of species refers to its colouration and pattern: marmoratus (Latin) = marbled.
