Leptohyphes nigripunctus Traver (spell).

Diagnosis: Very little is known concerning this species. The whitish pronotum, grayish head, dark gray mesosternum, and yellow femora evidently distinguishes it from other known adults in Central America ( Traver, 1958).

Description: Male Adult: Length. Body, 4.0 mm; forewings, 4.0 mm; hind wings, 1.0 mm. General coloration: pronotum yellowish white, meso- and metanotum reddish-brown; abdomen yellowish-white with reddish brown. Head: dorsally grey, ventrally white; antennae white. Thorax: pronotum yellowish-white, shaded with pale grey, lateral margins with blackish shading; meso- and metanotum bright reddish-brown with grey shading medially and on pleura. Legs: femora yellowish; tibia and tarsus grayish-black. Forewing: membrane whitish; veins whitish, except C, Sc, and R grayish basally; no figure or description of the venation has been published. Hind wing: membrane pale; two longitudinal veins present. Abdomen. Segments two through six yellowish-white, basal and apical segments light reddish-brown; each nota with pale grey band medially. Genitalia: reported as the peterseni type (see “Discussion” below), which has forceps threesegmented, penes with basal half fused, distal parts divergent, “Y” shaped. Larva: Unknown.

Distribution: Known from Guerrero, Mexico ( McCafferty, 1985) and Antimano, Venezuela.

Discussion: Described by Traver (1943) from a single male subimago from Antimano, Venezuela (located near the capital, Caracas). The genitalia were described as the peterseni type (“Y” shaped, typical for all known male adults of the genus), but lost while being prepared for mounting. The sketch of the hind wing given by Traver (fig. 3, Traver, 1943) is also typical of male Leptohyphes . The whitish pronotum distinguished it from other known adults in Central America ( Traver, 1958). McCafferty (1985) reported it from Guerrero, Mexico, its only other documented record. Molineri (2003) briefly mentioned this species in his revision of the South American Leptohyphes , but did not attempt to diagnosis it from other species. Despite attempts to located the type specimen, it cannot currently be found. The brief description given above is taken from Traver’s (1943) original description.

Type material examined: None.

Other material examined: None.
