Type material (1).

Holotype: CR: Puntarenas, San; Gerardo de Dota, Savegre; Lodge, Canto de las Aves; trail; 19-21 FEB 2008, SA Marshall; debut00319381 (MNCR).

Etymology.

The species was named after Steve Marshall, who collected the specimen of this species for this study.

Diagnosis.

The elongate labrum, which is longer than wide, is unique among all Lycinella species. The pronotum solid yellow-brown is shared only with L. milleri , which has a short labrum. The only known male genitalia are broken (Figure 33) and so cannot be fully diagnosed.

Description.

General dorsal coloration dark brown, pronotum orange (Figure 8). Antennae subserrate; antennomeres IV–XI dorsoventrally flattened (Figure 17); 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 wider than long. 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, posterior margin straight, anterolateral angles rounded, with posterolateral angles 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 weakly visible. Humeral region rounded (Figure 8). Legs slender, elongate. Pro- and mesocoxae without stemmata. Aedeagus with parameres 2 × longer than phallobase; phallobase rounded posteriorly (Figure 33).

Length (pronotum+elytra): 4.8 mm. Width (across humeri): 1.0 mm.
