1. Palliolatrix quadrimaculata (Champion) , comb. n.

( Figs. 1, 2 )

Peridinetus quadrimaculatus Champion 1907: 179–180 . Holotype male, dissected by me, labeled: “Type”, “ ♂ ”, “sp. figured”, “Senahu,/ Vera Paz./ Champion.”, “B.C.A. Col. IV.5./ Peridinetus / 4­maculatus,/ Champ.”, handwritten “P. 4­maculatus/ Cham” (BMNH). Hustache 1938 (cat.); O’Brien & Wibmer 1982 (cat.).

Redescription. Total length 5.2 mm, standard length 4.9 mm (n=1). Integument brown, antenna and legs partially reddish; basic vestiture of moderate­sized, light­colored scales; elytra with black scales in short, rhombic fascia near middle of interstriae 3–5 and in small macula on subapical callus (ventral and lateral vestiture indistinct and partially abraded in type specimen). Rostrum 0.88× length of pronotum, dorsal curvature at antennal insertion moderate, finely costate medially and dorsolaterally, portion distal to antennal insertion 0.34× length of rostrum. Pronotum 1.08× longer than wide, greatest width at base, sides very slightly converging toward middle, then narrowed and tubulate in front. Elytra 1.67× longer than wide, humeri 1.50× wider than pronotum; interstria 9 convex, not clearly costate, preapical callus produced. Legs with moderate femoral tooth, hind tibia produced ventrally, ventral margin with few hairs, base slightly curved.

Distribution. Guatemala and probably adjacent Mexico (see discussion).

Discussion. In addition to the holotype from Senahú in Guatemala, I apply the name provisionally to two specimens from Jitotol in Chiapas, Mexico and one specimen from Zapotitlan in Suchitepequez, Guatemala (CWOB 3). The latter ( Fig. 2 ) has a dense fringe of hairs on the ventral edge of the hind tibia. The entire material forms a morphological complex of possibly more than one species.
