Diagnosis
Teloneria apicata and T. bimaculata 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 of almost the same length. All Teloneria species have the gena and postpronotal lobe yellow, but only T. apicata have the frontoorbital plate, occiput, mid coxa and femora black. Also, T. apicata and T. bimaculata bear a mostly black frontal vitta, with a small anterior area yellow. The head of T. apicata is at most slightly elongate and not evidently elongate as in T. bimaculata and T. juceliae sp. nov., and the anterior fronto-orbital seta is well-developed but less than half the length of the posterior fronto-orbital seta. Males of T. apicata bear an anteroventral row of long, spine-like setae.

Redescription
Male
MEASUREMENTS. Body length 4.7–5.0 mm. Wing length 4.7–4.9 mm and width 1.2–1.5 mm.
HEAD (Fig. 1A). First flagellomere ovate, narrowing on distal half, with broad apex (Fig. 7J). Anterior margin of frons slightly convex, projecting over small antennal base without surpassing anterior margin of parafacial (Fig. 7N). Fronto-orbital plate broad and shiny, sometimes with three or four fronto-orbital setae. Parafacial pale brown. Vertex and median occipital sclerite blackish-brown; outer vertical seta aligned with four postocular setae, almost of same size; row of 2̄5 occipital setae very short.
THORAX (Figs 1C; 8G). Dorsal longitudinal stripe of faint gray pruinescence; anterior notopleural seta subequal to posterior notopleural seta. Femora entirely brown; fore femur with several long anteroventral setae, diminishing in size distally and absent on distal third; ventro-apical surface of fore fourth tarsomere with four very thick setae.
ABDOMEN. Dark brown with several long setulae laterally on posterior half of syntergite 1+2. Syntergosternite 8 protrudes basally, with two distal setae; epandrium twice the length of syntergosternite 8, reaching posterior half of third segment ventrally; surstylus narrow linear; cercus broad linear, slightly narrowing on distal third, with broad round apex; length of cercus half length of epandrium and twice length of surstylus; distiphallus partially sclerotized, flattened and bifurcated, with distal and coiled membranous area bearing a sclerotized spike (Fig. 2A).
Female
Body length 4.6–5.6 mm. Fore femur and fourth tarsomere without thick ventral setae. Oviscape brown and shiny.
Distribution
Thailand, Malaysia * (Pahang, Sarawak), Indonesia (Sumatra).
Remarks
Despite being a syntype labeled as TYPE, we are hereby designating the male specimen in the most complete condition of preservation as lectotype to stabilize the taxonomic concept of this species and its name.
