Holotype: ♂. Type locality: NIC: Nueva Segovia, Cerro Jesus, 1300 m, VI/7-13/2015, Morris & Wappes (FSCA).

D i a g n o s i s: The genus Madoniella PIC was revised in 2011 (OPITZ 2011b). This work includes a key to species. Madoniella delta specimens key out to M. kuhlorum OPITZ, from which the M. delta specimen differs by lacking a posterolateral extension of the anterior block. Also, the phallobasic apodeme is very short in the available specimen of M. delta, which is not the case in M. kuhlorum specimens.

D e s c r i p t i o n: Size: Length 5.0 mm; width 1.5 mm. Form: As in Fig. 296. Color: Cranium red-castaneous; antenna brown, except scape testaceous; pronotum bicolored, mostly black, with a triangular red mark that extends laterally along pronotal arch; pterothorax black; elytra mostly dark brown, insignia well developed, anterolateral and anterocentral extensions of anterior block poorly developed, posterolateral extension of anterior block absent; legs and abdomen brown. Head: Cranium coarsely punctate; antenna (Fig. 66) capitate, funicular antennomeres filiform, progressively shorter towards capitulum, capitular antennomeres 8 and 9 triangular, antennomere 10 ovoid; eyes large, ommatidia small, eye notch large, eye narrower than frons (EW/FW 20/30). Thorax: Pronotum (Fig. 191) quadrate, coarsely punctured (PW/PL 62/62), disc deeply concave paralaterally near pronotal collar; discal and lateral trichobothria prominent; elytral asetiferous punctures striate (EL/EW 155/40); anterior margin of protibia with 4 spines. Abdomen: Pygidium scutiform; aedeagus as in Fig. 223.

N a t u r a l H i s t o r y: The available specimen was collected during June, at 1300 m.

D i s t r i b u t i o n: This species is known from Nicaragua.

E t y m o l o g y: The trivial name, delta, is the Greek capital letter Δ; with reference to the shape of the red making at the anterior-middle of the pronotal disc.
