description: Alloeohellica new genus
(Fig. 4)
Type species: Alloeohellica faundezi sp. nov., by present designation.
Diagnosis. This genus is characterized by the long hairs on the labium and legs, by the large eyes, and by the elongate hemelytra, which exceeds beyond the apex of the abdomen.
Description. Oval elongate, medium-sized species; in lateral view, pronotum (without lateral carina) and head forming medial angle with respect to dorsal profile (Fig. 4 B). Dorsal surface covered with narrow, scattered punctures.
Head (Fig. 5 B). Short, wide; lateral margins not flattened; head ventrally sparsely punctured. Anteclypeus with few punctures on basal third, extending well beyond apices of paraclypei, which are apically narrow and lateral margins curved, and mesial margins opening towards apices, causing anteclypeus to be twice as wide apically than basally. Antennae long, surpassing base of pronotum (when stretched posteriorly); segment I reaching, or sometimes slightly surpassing apex of head; segment II slightly longer than III; segments II and III longer than segments IV and V. Bucculae narrow, covering less than half the broadness of labial segment I, with a few basal punctures, appearing smooth. Labium short, only reaching base of mesosternum; covered by erect hairs which are longer than broadness of labial segments, aligned along its ventral margin (Fig. 4 E); labial segments I and II narrow in diameter, segment III slightly enlarged in diameter, segment IV less enlarged.
Thorax. Lateral margins of pronotum straight, not carinate. Scutellum 0.2 times wider along base than medial length. Ostiolar peritremes small, twisted, protruding, each with apical spiniform process. Legs with sparse, long, erect hairs on ventral surfaces (Fig. 4 D); femora broader than tibiae, but not particularly short or robust; tibiae not flattened ventrally on apical halves; tarsomere I much shorter than segment II, also with long hairs.
Abdomen. Basi-abdominal spine present, somewhat more elongate than in other genera of this complex, reaching bases of posterior coxae, apically rounded. Extreme margins of connexival segments smooth. In males, lateral margins of 7th sternites slightly curved; pygophore with setae along posterior margin, grouped in loose patches.
Etymology. prefix Alloios - from the Greek, meaning “of another kind, different” (Brown, 1985) and -hellica, from Hellica, thefirstdescribed genus of this group. The gender is feminine.
Discussion. Alloeohellica gen. nov. differs from the closely related genus Hellica by the shorter and wider head, the larger eyes, the longer antennae, the erect pilosity on the ventral surfaces of labium and legs, which is greater in length than the width of the segments (much more so than in the other species of this complex), and by the particular shape of pygophore and the apically spatulate parameres.
