Diagnostic characters: Measurements, see Table IV.
Male:
Characterized by the following combination of characters: head and pronotum reddish-brown, hemelytra and antennae brown, legs and labium, pale brown, abdomen slightly darker; antennal segment II thickened towards the apex, slightly longer than length of head; antennal segments (I:II:III:IV) 1: 2.9: 2.3: 2.4; head prolonged anteriorly from base of antennae; hemelytra and scutellum punctured (
Fig. 133
); these punctures not so deep as in
Lasiochilus
; every puncture with an emerging seta; forefemora long, slightly thickened; foretibiae armed with row of long spines on inner margin (
Fig. 132
); pads medium-sized; ostiolar peritreme opening acute apically and slightly elevated; meso- and metasternum not sulcate medially, the latter slightly elongated apically (
Fig. 134
); copulatory spines short, slender and not densely arranged (Fif. 135); left paramere linear, parallel-sided, not acute apically (
Fig. 136
).
Female:
Similar to male in measurements and coloration. Antennal segments (I:II:III:IV) 1: 2.6: 2.4: 2.4.

D. punctipennis
.
Male. 132, Pronotum and foretibia showing the spines (Sp) on internal margin; 133, Scutellum and hemelytron; 134, Metasternum; 135, Copulatory spines (Csp); 136, Pygophore showing left paramere (LP).
Discussion: Easily recognizable from other species of
Dilasia
by the punctures typical of those seen in
Lasiochilus
,
though not as deep as in this genus. However, the other characteristics of
Dilasia
are presents in this species: male genitalia with a row of teeth on the inner margin of foretibiae, series of teeth on foretrochanters, and the grouping of apically acute, spiniform copulatory teeth on apical left margin of sternite VI, as well as a nearly straight left paramere.
