Redescription

Holotype female. Integument black; prothorax reddish. Head inconspicuously pubescent.

Antennae exceeding middle of elytra by about two segments. Segments 3–5 rugose-punctuate, 6–11 pubescent. Segmenst 3–5 subcylindrical, 3, 4 similar-sized, little shorter than 5; 6 barely longer than 5, more expanded apically; 7–10 decreasing in length, slightly expanded at apex, not particularly shortened or swollen; 11 suboval, as long as 3.

Prothorax subparallel at sides, base as broad as middle, slightly attenuate to apex; opaque, glabrous and impunctate. Pronotum somewhat raised at apical half; latero-basal gibbosities rounded, feebly prominent.

Elytra somewhat sinuously narrowed before middle. Disk depressed; dorsal costa prominent from base almost to apex. Surface densely clothed by whitish pubescence, almost obscuring punctures. Punctures moderately fine, deep, not seriate, separated by more than one diameter; a single row of punctures between dorsal and lateral costae, except at apical third with two rows. Margins weakly asperate. Elytral apices rounded-truncate.

Peduncles of femora shallowly sulcate. Metafemora surpassing elytral apices by about half the length of club. First segment of metatarsi 1.3 times as long as the following two combined.

Measurements (mm) female holotype. Total length, 7.0; prothorax length, 2.0; maximum width of prothorax, 1.3; elytral length, 4.5; humeral width, 1.6.

Type material

Holotype female ( BMNH), examined, from Nicaragua: Chontales, labelled as follows: (1) Chontales; Belt; (2) chontalensis Bates ; (3) Ex-Musaeo H. W. Bates.

Remarks

See the remarks on D. mineira . Dihammaphora chontalensis have been recorded only from Central America ( Nicaragua, Costa Rica and Panamá) ( Bates 1872: 188, 1880: 61; Chemsak et al. 1992: 74; Maes et al. 1994: 11; Monné 2005: 520; Monné and Bezark 2008: 138).
