Type material (1).

Holotype: COSTA RICA: San Jose; 19 km S., 3 Km W. Empalme; 9.650°N, 83.866°W; DEC1992, 2600m; P Hanson Malaise (USNM).

Etymology.

Noun, neuter. This species is named in honor of the great North American Lycidae systematist, Richard Stuart Miller.

Diagnosis.

The unicolorous yellow-brown pronotum is shared with only L. marshalli , but the stronger elytral costae of L. milleri (Figure 6) and its wider–than-long labrum will distinguish it easily from L. marshalli (Figure 8). The male genitalia is also unique, with the emarginate posterior margin of the phallobase (Figure 31) shared only with L. publiesae (Figure 36), which has a bicolored pronotum and rounded apex of the median lobe.

Description.

General dorsal coloration dark brown, pronotum orange (Figure 6). Antennae subserrate; antennomeres IV–XI dorsoventrally flattened (Figure 15); scape subconical, antennomeres II and III short, subequal in length, approx. 1/4 length of I; antennomere IV elongate, approx. 1/3 longer than I; antennomeres V-X gradually decreasing in length; antennomere XI elongate. Mandibles elongate. Labrum elongate. Maxillary palpomere I short, approx. 1/3 length of II, which is cylindrical, palpomere III approx. half length of II, IV elongate, subequal in length of II, acuminate, densely setose. Labial palp 3-segmented, palpomere I and II subequal in length, palpomere III elongate and cylindrical, acuminate, densely setose.

Pronotum trapezoidal, anterolateral angles rounded, with posterolateral angles and pronounced and acute, divergent, with weakly visible longitudinal carina in anterior portion of pronotum, bifurcate posteriorly forming weakly visible areola. Prosternum V-shaped; posterior margin rounded; laterally reaching hypomeron.

Elytra approx. 10 × longer than pronotum; costae strongly visible. Humeral region rounded (Figure 6). Legs slender, elongate. Pro- and mesocoxae without stemmata. Aedeagus with median lobe tapered apically, 1.5 × longer than parameres; parameres 2.5 × longer than phallobase; phallobase emarginated posteriorly (Figure 31).

Length (pronotum+elytra): 3.4 mm. Width (across humeri): 0.8 mm.

Distribution.
