(Figs. 2, 7, 13, 43)
Description. Holotype male. Dorsal color. Head black with three dark orange stripes, one on midline reaching apex of tylus, other two running between eye-ocelli and covering antenniferous tubercles; postocular area black; antennal segment I dark reddish brown with ventral surface dark orange, segment II orange with narrow dark reddish brown stripe on dorsal surface, segment III orange, and IV yellow with distal third pale brown and apex yellow; pronotum dark reddish orange with anterior border of collar, humeral areas, humeral angles, and posterior margin black; posterolateral borders and posterior border yellow; scutellum dark reddish orange with three pale reddish orange stripes, one on midline, other two covering lateral borders; apex dark yellow; clavus and corium dark reddish brown with claval and corial veins pale reddish orange; corial veins yellowish distally, forming a distinctive “H” pattern; hemelytral membrane bronzy brown; connexivum black, upper margin reddish orange and anterior third pale yellowish orange; dorsal abdominal segments black. Ventral color. Head and thorax pale yellowish orange with numerous black discoidal spots; midline of head, prosternum and mesosternum laterally black; rostral segments pale yellowish orange (apex of IV black); fore and middle legs pale yellowish orange with femoral spines black; hind leg with coxae black and inner surface yellowish orange, trochanters yellowish orange, femora dark reddish orange with dorsal surface and spines dark reddish brown, tibiae dark to pale reddish orange, undilated portion and tarsi pale yellowish orange; abdominal sterna pale orange; genital capsule pale orange with black discoidal spots. Structure. Head longer than wide, shorter than maximum length of pronotum; tylus blunt, slightly exceeding juga; antennal segment IV longest, III shortest, and II longer than I; rostrum reaching anterior third of abdominal sternite III; rostral segment IV longest, III shortest, and I longer than II. Thorax. Pronotum wider than long; anterolateral border entire, posterolateral border serrate; humeral areas medially produced on lateral projections; humeral angles subacute; calli uniformly elevated; raised area between calli with two small circular pits (Fig. 2); hind tibiae with outer dilations phylliform, at least with two deep emarginations occupying 64 % of maximum length of tibiae; inner dilations lanceolate, shorter, occupying 58 % of maximum length of tibiae (Fig. 7). Genital capsule. Posteroventral edge with straight “U” deep concavity at midline; prongs absent (Fig. 13).
Integument. Body surface dull. Head, pronotal disk including the calli, scutellar disk, legs, middle third of thorax, and middle third of abdominal sterna clothed with erect, silvery pubescence; clavus, and corium clothed with short sized bristle-like setae; antennal segment I densely clothed with long, erect, silvery bristle-like setae, segments II and III sparsely clothed with short, erect, silvery bristle-like setae, IV with tiny setae; head, collar, calli, scutellar disk, thorax, abdominal sterna and genital capsule almost impunctate; pronotal disk, clavus, and corium densely punctate.
Variation. 1, rostrum reaching middle third of abdominal sternite II.

Puntarenas, Peninsula de Osa, Rancho Quemado, 200 m, IV-1992, leg. K. Flores (UNAM). 1 male, Costa Rica, Prov. Puntarenas, P. N. Corcovado, Est. Sirena, 0–100 m, III-1992, leg. G. Fonseca (INBIO).
Etymology. Dedicated to Oscar Federico Francke Ballve, distinguished Mexican arachnologist.
Distribution. Costa Rica.
Diagnosis. This new species is related to L. arenalensis Brailovsky & Barrera, L. brevirostris Barber and L. quadricollis (Westwood) by having the thorax and abdomen with numerous, small, black dots, without yellowish maculae or yellowish stripes; dorsal abdominal segments black without median pale yellow longitudinal fascia; yellowish transverse fascia on corium irregular or absent; rostrum short, reaching anterior third of abdominal sternite II or III; rostral segment IV shorter than maximum length of antennal segment I; pronotal disk without contrasting yellowish areas; anterolateral margins of pronotum entire; and outer dilations of hind tibiae phylliform, occupying less than 70 % of maximum length of tibiae. In L. brevirostris and L. quadricollis the rostral segment IV is entirely black, in L. arenalensis and L. franckei sp. nov., pale chestnut orange with apex black. Leptoglossus franckei is segregated by having the corium chestnut orange with veins yellowish distally, forming a distinctive “H” pattern, the posterolateral borders and posterior border of pronotum pale yellow, the total length of antennal segment I longer than 3.00 mm, and the total body length longer than 18.00 mm. In L. arenalensis the corium is entirely pale reddish brown, the posterolateral borders and posterior border of pronotum dark reddish brown (sometimes suffused with dark orange), the total length of antennal segment I shorter than 2.50 mm, and the total body length less than 17.00 mm.
