Diagnosis
Teloneria bimaculata and T. apicata can be differentiated from T. juceliae sp. nov. and T. ladyae sp. nov. by the general darker color and the inner vertical and outer vertical setae being of almost the same length. Teloneria bimaculata and T. juceliae sp. nov. have the head elongate and mostly yellow, except for the black frontal vitta and pale brown ventral half of the occiput in the former. Other brown-colored structures that differentiate T. bimaculata from the yellow T. juceliae sp. nov. and T. ladyae sp. nov. are the proepisternum, femora (yellow only at base), and dorsal scutum and pleuron (yellow at postpronotal lobe). Exclusive characters of T. bimaculata include four fronto-orbital setae of almost the same length and the female wing cells r1 and r2 +3 being basally infuscate.

Redescription
Male
MEASUREMENTS. Body length 5.3–6.3 mm. Wing length 4.5–5.9 mm and width 1.2–1.6 mm.
HEAD (Figs 1B, 6C, E, 7O). First flagellomere ovate, narrowing on distal half, with broad apex (Fig. 7K). Anterior margin of frons convex, projecting over small antennal base without surpassing anterior margin of parafacial (or at most surpassing it very discreetly). Fronto-orbital plate broad and shiny. Parafacial pale brown to yellow. Vertex blackish-brown and median occipital sclerite paler; outer vertical seta aligned with 2̄4 postocular setae of almost same length; row of 2̄4 very short and hair-like occipital setae.
THORAX (Figs1D, 8H). Dorsally brown or pale brown; dorsal longitudinal stripe of faint gray pruinescence; anterior notopleural seta subequal to posterior notopleural seta. Fore and mid coxae yellow, hind coxa brown. Femora brown with yellow base; fore femur without long anteroventral setae; fore tarsomeres with ventral row of short thick setae.
ABDOMEN.Dark brown,with several long setulae laterally on posterior half of syntergite1 + 2.Syntergosternite 8 with three median setae; epandrium 1.5̄2.0 times as long as syntergosternite 8, reaching anterior half of third segment ventrally; distal margin of epandrium extended laterally; surstylus narrow linear; cercus broad and spatulate; length of cercus ½ to ¾ length of epandrium and three times length of surstylus; distal margin of cercus with conspicuously long and thick setae; distiphallus partially sclerotized, with median membranous area distally bifurcated in a sclerotized spike and a membranous coiled up tube (Fig. 2B).
Female
Body length 4.9–5.5 mm. Fore femur without strong ventral setae; tarsomeres without thick ventral setae. Oviscape brown and shiny.
Distribution
Taiwan, Malaysia * (Pahang, Selangor, Sarawak), Indonesia (Sumatra).
Remarks
The abdomen of the holotype is lost. However, the basally infuscate wing cells r 1 and r 2+3 indicate that it is a female specimen. The cercus morphologically differentiated varies in length among specimens and presents conspicuously long distal setae. According to Van Steenis & Hippa (2012), the material labeled as ‘ Siam: Talum’ by O. Robinson and N. Annandale (9 Jan. 1902) was collected in Lubok, Tamang, Pahang, F.M.S.
