Curculio discreticoxis (Marshall), Dalla Torre 1932: 25 (comb. n.); Pelsue 2010: 47 (lectotype) (present designation): “W. Sarawak / G. Bryant Coll. / 1919-147,
Type species: A syntype was stolen in a Paris theft from the senior author while returning specimens to the BMNH. Malaysian Borneo: Sarawak, 1 Ƥ with the following data as the one stolen and lost. W. Sarawak /G. Bryant coll./ 1919-147, 1 Ƥ Paralectotype: 1 female: “Mt. Matang./W. Sarawak /G.E. Bryant/13.2 14/ 1000 ft ” and “G. Bryant Coll./1919-147.” (BMNH)”
Material examined: 2 3 Malaysia, Sabah, Crocker Range, Mt. TrusMadi, 3-26-2001. 1 (BMNH) 1 (CWOB) 4 Ƥ same data as males. 2 (CWOB) 2 (FWPC).
Redescription: Habitus (Figs. 25–26) 3 2.7–2.8 mm (mean= 2.75 mm, n=2) in width; derm fuscopiceous with fuscous highlights; rostrum abruptly emerging from frons, tubular in shape, rubiginose; pronotal disc with median vitta, lateral vittae from base to midpoint and anterior macula of recumbent clavate luteous scales; scutellum as long as wide densely clothed with luteous scales; disc of elytra with short, median vittae on intervals 1 and 2 from base of scutellum to midpoint and two small macula in distal 1/3 of luteous, clavate, scales on stria 2; pro-, meso-, and metafemoral teeth small; male with long inner bifid process on metatibia (Fig. 29), female with no uncus; metafemur exceeding apex of elytra; legs appear long and spindly. Male genitalia: Median lobe 0.6 mm in length, almost straight for 1/4 of length, there sharply deflexed to apex, thickened in deflexed portion, then narrowing to apex, 0.2 mm in width; apodeme 1.2 mm in length (Figs. 47–48). Female: 2.7–3.3 mm (mean= 2.9 mm, n=4) in length; 1.1–1.8 mm (mean= 1.27 mm, n=4) in width. Female genitalia: Spermathecal ramus and collum united with slight dorsal declivity between ramus and collum, corpus basally wide, narrowing slightly, cornu abruptly narrowed to rounded apex (Fig. 57).
Differential diagnosis: This species can be distinguished from other members of the genus by the scale pattern on the pronotum and elytra. It is similar to Pseudoculio vittatus sp.n. in coloration and form, but differs in scale pattern on the elytra, with P. vittatus having elongate vittae on the suture, whereas P. discreticoxis has short luteous vittae distad of the scutellum to the midpoint and 2 maculae in the distal 1/3 of the elytra. This species appears almost identical to Pseudoculio confusicoxis sp.n. in scale pattern and coloration, but differs in the form of the inner tibial hook which is blade-like with a ventral comb of stiff bristles (Fig. 30) in P. confusicoxis, rather than an apical bifid projection, and in the form of the male genitalia (Figs. 49–50) and the female spermatheca (Fig. 58).
