Lectotype of Callimerus rusticus Gorham designated here: "Celebes / Callimerus rusticus, Gorh. / Gorham Type / Museum Paris, Coll. H. S.

(RMNH, 1♀); Holotype of Lemidia bipunctatus Kuwert: "S. Celebes, Aug.-Sept. '91, W. Doherty / Ex-Musaeo, W. Rothschild, 1899 / Museum Paris, 1952, Coll. R. Oberthür / Lemidia bipunctata Kuw. Type / Holotype: Lemidia bipunctata Kuwert, 1893, ♂, det. Yang G. Y., 2011" (MNHN, ♂; Figs 44-45).

Note on Type material.

The original description of Callimerus rusticus Gorham mentioned two specimens, but the name-bearing type was not fixed. We found both syntypes in MNHN and RMNH respectively, and designate the male from Coll. Gorham in MNHN as lectotype here to express the taxonomic purpose of fixing the name to a single specimen and preventing further uncertainty regarding the taxon to which the name is applied.

The original publication of Lemidia bipunctatus Kuwert noted that only one specimen was examined, so the holotype was originally fixed by monotypy.

Diagnosis.

This species can be rapidly distinguished from other species of the latifrons species-group by posterior spot on elytron being located lateral-apically, bar-shaped, with a length to width ratio of about 4:1 (Fig. 41).

This species is most similar to Callimerus pectoralis ; the difference between them is provided in the diagnosis section under Callimerus pectoralis .

Description.

Size:length 7.5-9.5 mm, width 2.4-3.0 mm. Color: Head yellow, mandibles black; pronotum yellow. Elytron yellow with two spots, anterior spot at basal fourth, posterior spot at lateral-apex; anterior spot round and small, clearly neither reaching outer margin nor suture, short diameter of anterior spot on elytron in most cases not greater than distance between that spot and elytral suture (Fig. 41, 44); posterior spot bar-shaped, length to width ratio about 4:1 (Fig. 41). Legs yellow with metacoxae mostly black. Prosternum yellow; mesepisternum black, mesepimeron and mesosternum yellow; metepisternum, metasternum and katepisternum black; abdominal ventrites yellow. Head: AL/AD about 1.0; EyD/EyW about 1.0. Prothorax: PL/PW about 0.8. Elytra: EL/EW about 1.8. Male terminalia: apices of parameres convergent (Figs 46-48); TML/TMW about 1.3; TMaL/TML about 0.22, outer margin of ventral membranous region slightly curved (Figs 48, 48a); SApL/SFL about 0.3 (Fig. 50); tergite VIII with posterior margin almost straight, sternite VIII with posterior margin shallowly concave (Figs 51, 52).
