Prodilis saopaulo González & Větrovec , new species

( Figs. 2 n-2ac)

Holotype ♂ “Saõ [sic!] Paulo / Bras. MRaz lgt / Mus. Pragense” ( NMP).

Diagnosis. The elongated body and entirely black dorsum, with greenish luster including head, pronotum and elytra identify this species ( Fig. 3n ). The entirely black dorsum does not appear in any known species of the genus except P. kristy Gordon & Hanley, 2017 from Brazil, but this species has a rounded body. Other species also have head, pronotum and elytra black, but these always present light areas on the head or in the borders and fore angles of the pronotum, and they are mostly circular in shape. The male genitalia also have the penis apex with an outer side 90° fold ( Figs. 2 ab-2ac), which is unique in the genus and in the tribe.

Description. Color pattern ( Figs. 2 n-2r). Body black, elytra with green metallic luster. Antennae yellow and mouthparts brown. Ventral side black, except abdomen dark brown with middle part of ventrites 1 and 2 black. Legs yellow. Pubescence yellowish white. Morphology. Body oblong, elongate, elytra depressed with slightly curved sides, almost straight medially, widest at middle of elytra ( Figs. 2 n-2q). Frons about twice the width of an eye. Eyes vertically elongated with almost parallel inner sides, twice as long as wide, short eye canthus 1/4 width of the eye. Clypeus with apical margin slightly concave ( Fig. 2r ). Antenna with ten antennomeres, the last four forming an oval club ( Fig. 2s ). Maxillary palpi lost. Pronotum widest near anterior border, advanced anterior angles and plain lateral borders ( Fig. 2n ). Mesoventrite T-shaped, apically truncate, prosternal process elongated, with lateral carina ( Fig. 2t ). Metaventrite without setiferous pit. Abdominal postcoxal lines complete, evenly rounded, extended slightly more than 3/5 distance to apical margin of ventrite ( Fig. 2u ). Dorsal punctures large and very regular, slightly larger in elytra, space between them about half the diameter in head and pronotum, slightly larger on elytra, separated by a diameter on average; ventral side punctures large, distributed, more coarse in the prosternum, mesoventrite and anterior border of the metaventrite, abdominal punctures small, sparse, separated by four diameters on average, a little more abundant on ventrite 5. Pubescence decumbent with hairs in each puncture, hair size about 3/4 length of scutellar shield, on pronotum and elytra concentrated on the lateral borders, scarce on ventral side. Male terminalia. Apex of ventrite 5 convex, rounded, apex of ventrite 6 triangularly notched in the center ( Figs. 2 u-2aa). Tegmen elongated, slightly more than three times as long as wide, phallobase short, transverse, with rounded posterior angles. Tegminal strut somewhat longer than the rest of the tegmen ( Figs. 2 v-2w). Penis guide symmetrical, more than four times longer than wide, with almost parallel sides in the basal half, slightly sinuous, maximum width at 2/3 of the length, then a small contraction before the rounded apex that is bifurcate, in lateral view parallel sides somewhat sinuous, with dorsal keel arched at the base, at the apical 1/6 sharply narrowed to end in a small hook ( Fig. 2 x-2z). Parameres about 1/8 shorter than the penis guide, curved inward, narrow at base, widening at the apical fourth, pubescence sparse and short at the apex ( Figs. 2 v-2w). Penis semicircular in the basal 1/2, then only slightly curved towards the inner side, but somewhat sinuous, presents at the apex a short fold very curved towards the outer side, ending perpendicular to the tube; penis capsule with aligned outer and inner arms, oblique with respect to the tube, the inner arm twice the length of the outer one, four times as long as wide, basal margin almost straight, slightly sinuous (Figs. ab-ac). Female. Unknown.

Measurements (mm): TL 2.0; PL 0.35; PW 0.9; EL 1.5; EW 1.2; GD 0.6.

Geographic distribution. Brazil, State of São Paulo.

Remarks. Gordon & Hanley (2017) in the revision of the tribe Cephaloscymnini recognized eight species of Prodilis and described 63 new species. The genus is distributed from Mexico to Argentina. Prodilis saopaulo n. sp. is assigned to the genus by the broad frons with the margins of the eyes almost parallel ( Fig. 2r ), and by the prosternal process with lateral carinas.

Etymology. The species is named after the state of S ã o Paulo, Brazil, where the species comes from.
