About Thiania suboppressa Strand, 1907
Thiania suboppressa Strand, 1907 is a species that displays sexual dimorphism, as noted in Strand's original description. Males reach a total length of 7.5 mm, while females are larger at 8.5 mm in total length. Males have several distinct morphological features: their mandibles are only slightly longer than they are broad, nearly hairless at the tip, and marked with deep transverse striping. The male patella is slightly longer than broad and rounded at its end, and the male tarsus is considerably longer than the two preceding segments combined. For females, the cephalothorax measures 3.4 × 2.7 mm, and the abdomen measures 5 × 2.7 mm. Female leg lengths in millimeters are as follows: leg I 8.1, leg II 6.8, leg III 6.9, leg IV 7.4. The combined length of the patella and tibia of female leg IV is 2.2 mm, while the tibia alone measures 2.7 mm. This species has a wide native distribution across East Asia, including Japan, China, and Vietnam, and has been introduced to Hawaii.
