Paranillopsis , new genus

Etymology. The name Paranillopsis is based on two classical words, the generic name Paranillus , and the suffix opsis, meaning similar to. Together, these words indicate that the new genus has features similar to, but not the same as, Paranillus .

Type species. Paranillopsis piguensis new species, here designated.

Diagnosis. Body elongate ( Fig. 1 ), depigmented, wingless; eye traces lacking; antenna long, extended to base of elytra; mentum tooth present; ligula with rounded paraglossae; elytral chaetotaxy of type A (anillienée), without discal fixed setae, except the basal scutellar.

Description. Length 1.06–1.57 mm. Head and elytra integument with microsculpture mesh pattern isodiametric ( Fig. 2 ), pronotum integument smooth; thick short pubescence present over the entire body. Uniform yellow brown color. Head almost same width as pronotum ( Fig. 1 ), compressed or not in middle. Eyes absent. With four fixed setae, two supraorbital ( Fig. 16 , sos), one fronto­paramedial ( Fig. 16 , fs), and one ocular ( Fig. 16 , os). Lateral frontal carina clearly visible (Fig. 19, lfc). Antenna moniliform with 11 antennomeres, long, extended to base of elytra, with thick pubescence from the second antennomere, antennomere 11 excavated ( Fig. 3 , e). Labrum ( Fig. 5 , l) with six setae dorsally and concave anterior margin ( Fig. 4 ); mandibles short with retinaculum and premolar tooth small and conical ( Figs. 9–10 ); maxillar palpomere 3 large ( Fig. 10 , mp 3) and palpomere 4 subconical ( Fig. 10 , mp 4); labium with mentum ( Fig. 6 , m) and submentum not fused; mentum with simple tooth ( Fig. 6 , mt), two setae each in umbilicate punctures at base of median tooth and two lateral setae, epilobes not evident; submentum with four to eight setae; labial palpomere 2 ( Fig. 6 , lp 2) with few setae, palpomere 3 slender ( Fig. 6 , lp 3), as long as palpomere 2; ligula with paraglossae broadly rounded apically ( Figs. 6 and 7 , pag); glossal sclerite ( Figs. 6 and 7 , gs) with two central subapical setae. Pronotum transverse, cordiform, maximum width anteriorly and lateral margins posteriorly convergent; with two setae on each side, one anterior and another posterior; posterior margin narrower than anterior ( Fig. 1 ); posterior angles distinct, sharp, and protruded. Elytra flat, long (three ot four times longer than wide), not extended to apex of abdominal tergum VIII, with humeral margin rounded or straight; lateral margins regularly denticulate throughout to insertion of umbilicate seta 8, each denticle at apex with small setula, basal setae present; discal setae absent; umbilical series ( Figs. 1 , 18 , and 21) of nine setae, each seta inserted in umbilicate setigerous puncture, in three groups: basal, with setae 1–4, medial, with setae 5 and 6; and apical, with setae 7–9; setae 2, 6, and 8 largest; setigerous punctures 1–3 equidistant in sequence; setigerous puncture 4 more isolated, four times distance from 3 as 3 from 2, and similar distance from 5; setigerous punctures 5 and 6 close together; setigerous puncture 7 displaced mediad, 8 and 9 close together in form of pair geminée (series type A or anillienée of Jeannel 1963). Recurrent groove present (Fig. 21, rg). Protibiae broad, with a large spur on dorsal surface ( Fig. 11 , ds). Apical spur displaced to the middle the tibia ( Figs. 11–12 , as). Abdominal sterna IV–VII with two paramedian setae; VIII with four. Gonocoxites wide, stylus arquate ( Fig. 13 ) with subapical setose organ with two nematiform setae ( Fig. 13 , ns) and two lateral strong ensiform setae ( Fig. 13 , es); spermatheca rounded ( Figs. 14–15 ).

Phyletic relationships. Paranillopsis is included within the subtribe Anillina because it shares with other members of the subtribe the following char­

excavation; epi, epipharynx; gs, glossal sclerite; l, labrum; lp 1, 2, and 3, lapial palpomeres 1–3; m, mentum; mp 3 and 4, maxillary palpomeres 3 and 4; mt, tooth of mentum; pag, paraglossa; pg, palpiger; T VIII, Tergum VIII.

acters: Eyes lacking and umbilical series of nine setae, and with the humeral group of four setigerous punctures, 1–3 close together near humerus, 4 distinctly posteriad 3. For drawing phylogenetic inferences within anilline genera there are two different character systems. The first hypothesis proposed by Jeannel (1937), and followed by others ( Jeanne 1973; Vigna Taglianti 1980), is based on the disposition of setae of the umbilical series of elytra. The second one, based on the presence and absence of median mentum tooth, was also proposed by Jeannel (1963), and stated that the arrangement of anilline genera on the basis of two types of umbilical series is inadequate to show relationships. Because the system used by Jeannel in 1963 takes into consideration more features than that used in 1937, we follow the second system to infer the phylogenetic relationships and systematic placement of Paranillopsis . Within the subtribe Anillina , Paranillopsis belongs to the division Phanerodonta ( Jeannel 1963), whose members have a mentum tooth, and within this group this genus is included in the phyletic series of Paranillus , because the elytra have lost discal setae, and the umbilical series is type A (anillienée). This phyletic line comprises only one genus, Paranillus , with eight species restricted to Madagascar. The new genus differs from Paranillus in details of the ligula, mentum, and in elytral length. In Paranillopsis , with ligula seemingly bilobed apically, the paraglossae are separate from one another and extended beyond the apex of the glossal sclerite; in Paranillus , with the ligula with apical margin truncate, the paraglossae are absent. In Paranillopsis epilobes are not evident; in Paranillus they are evident. In Paranillopsis , the elytra are not extended to abdominal tergum VIII; in Paranillus , tergum VIII is covered by the elytra. Thus Paranillopsis represents an additional clade (phyletic series of Jeannel 1963) in South America, because the other Neotropical genera are grouped in different phyletic series ( Jeannel 1963; Reichardt 1970; Vigna Taglianti 1973; Mateu 1980; Etonti and Mateu 1992; Zaballos 1997).
