Description

(Female). Body length 2.6 mm.

Colour. Head and mesosoma black, coxae black to dark brown (Fig. 1 A, C – G View Figure 1 ); metasoma, apex of scape, pedicel, and thickened four apical flagellomeres dark brown, base of scape, other flagellomeres, and legs brown (Fig. 1 A, J, K View Figure 1 ); palpi yellow (Fig. 1 A View Figure 1 ); fore wing disc slightly infuscated, hind wings virtually transparent (Fig. 1 B View Figure 1 ); wing venation light brown (Fig. 1 B View Figure 1 ).

Head. Slightly longitudinal in frontal view with medium long malar distance (Fig. 1 C View Figure 1 ); lateral margin of toruli raised; width of the head slightly wider than the maximum width of the mesosoma, densely pubescent (Fig. 1 A, I View Figure 1 ); eyes medium-sized, covered with erect setae (Fig. 1 C – E View Figure 1 ); slightly crenulate ocular impressions along the inner margin of the eye (Fig. 1 C, E View Figure 1 ); slightly elongated areolae between eyes and ocellar foveae of lateral ocelli (Fig. 1 C, E View Figure 1 ); median ocellus diameter 1.2 × LOL (lateral ocellar line) (Fig. 1 C, E View Figure 1 ); occipital carina straight, with lateral part slightly posteriorly protruding (Fig. 1 D, E View Figure 1 ); anterior ocellar fovea elongated and ventrally extended into facial sulcus, reaching dorsal margin of antennal scrobe (Fig. 1 C, E View Figure 1 ); intertorular sclerite and clypeus with pubescence (Fig. 1 C View Figure 1 ); interocular distance 0.4 × head width (Fig. 1 C View Figure 1 ); antennae with four apical flagellomeres distinctly thickened (Fig. 1 A View Figure 1 ); scape 1.23 × the pedicel and 1 st to 4 th flagellomere combined (Fig. 1 A View Figure 1 ); pedicel about equal to the length of the 1 st flagellomere (Fig. 1 A View Figure 1 ); 4 th and 5 th flagellomeres about equal in length and width, width of 4 th flagellomere 1.11, and 5 th 1.26 × their length, respectively (Fig. 1 A View Figure 1 ); the 6 th – 8 th flagellomeres not transverse, width of 6 th flagellomere 0.78, 7 th 0.69, and 8 th 0.38 × their length, respectively (Fig. 1 A View Figure 1 ).

Mesosoma. Mesoscutum transverse, width 2.0 × its length (from dorsal view) (Fig. 1 F View Figure 1 ); notauli incomplete, present in anterior one third (Fig. 1 F View Figure 1 ); mesoscutum and - scutellum with no distinct areolae (Fig. 1 G View Figure 1 ); scutoscutellar sulci converge medially, adjacent to transscutal articulation (Fig. 1 G View Figure 1 ); mesometapleuron with longitudinal striations in dorsal two thirds, smooth in ventral one third (Fig. 1 I View Figure 1 ); lateral propodeal projections distinctly long and oriented posteriorly, tip of the projections amber-coloured (Fig. 1 G, H View Figure 1 ); median propodeal projection overhangs the anterior margin of the metasoma with its apical half, with slightly rounded tip from dorsal view (Fig. 1 G, H View Figure 1 ).

Legs. Metacoxa with few longitudinal striations (Fig. 1 A, I View Figure 1 ); metafemur slightly thickened, length 3.8 × its maximum width (Fig. 1 A View Figure 1 ).

Etymology.

The specific epithet chularoipaad is derived from “ Chula ”, referring to Chulalongkorn University, and “ roi paad ”, which means “ one hundred and eight ” in Thai, commemorating the 108 th anniversary of Chulalongkorn University in 2025. The name is treated as a noun in apposition.
