Diagnosis. The new species can be distinguished from other species of Tetralonioidella by its unique shape of S8, apical margin of median process of S8 concave, and with a projection medially.

Description. Male, BL 9.5 mm ( Fig. 18a View Figure 18 ); head broader than long, HW: HL=66: 50 ( Fig. 18b View Figure 18 ); gena distinctly narrower than eye, GW: EW = 8: 16; width of metasoma slightly broader than the width between the tegulae, MtW: MsW = 82: 78. Clypeus broader than long ( Fig. 18b View Figure 18 ); apical margin of labrum slightly concave ( Fig. 18c View Figure 18 ); antenna short, reaching front margin of tegulae; scape conically broadened, as long as F1 to F3 together, flagellomere equal in breadth, F1 longer than broad, nearly 1.2 times as long as broad, F2 long than broad, nearly 1.4 times as long as broad, F3 equal in length with F1, about 1.2 times as long as broad, F4–F10 equal in length, nearly as long as broad, F11 rounded apically, equal in length with F2, about 1.4 times as long as broad ( Fig. 18d View Figure 18 ); fore wing with distinct numerous papillae apically ( Fig. 19a View Figure 19 ); scutellar spines short and broad, pointed apically, barely visible between pubescence; inner ramus of hind tarsal claw axe-shaped, arolium present ( Fig. 19b View Figure 19 ); ventral surface of apical part of S7 with dense setae laterally, median part straight, with sparse setae ( Fig. 19c View Figure 19 ); apical margin of median process of S8 slightly concave, with a projection medially ( Fig. 19d View Figure 19 ); genitalia as illustrated in Fig. 19e View Figure 19 (in dorsal view) and Fig. 19f View Figure 19 (in lateral view), basal part of gonostylus with crescent-shaped process dorsally, and the process with dense long hairs along dorsal margin( Fig. 19f View Figure 19 ). Clypeus black ( Fig. 18b View Figure 18 ); mandible dark reddish-brown; labrum blackish-brown except apical part yellowish-brown ( Fig. 18c View Figure 18 ); antenna dark blackish-brown beneath ( Fig. 18d View Figure 18 ); tegula yellowish-brown ( Fig. 18e View Figure 18 ); all legs dark reddish-brown; hind tarsal claw blackish-brown apically ( Fig. 19b View Figure 19 ). Scutum pubescence yellowish-white ( Figs 18a, e View Figure 18 ); clypeus, periphery of antennal socket, supraclypeal area, paraocular area and front surface of scape covered with sparse white hairs ( Fig. 18b View Figure 18 ); vertex, genal area, scutum, scutellum, metanotum and episternum covered with dense and long yellowish-white hairs ( Figs 18a–b, e View Figure 18 ); all metasomal terga uniformly covered with thin and short yellowish hairs, and the hairs on T3-T5 denser than that on T1–T2 ( Fig. 18f View Figure 18 ).
