Archaeoglenes loebli Iwan and Kamiński, new species (Figs. 1, 3, 5A, E) Diagnosis. T h i s s p e c i e s i s s i m i l a r t o Archaeoglenes pecki Lawrence by having sexually dimorphic tarsal formulae (males 3-3-3, females 4-4-4) (Fig. 3I, J). Both species can be easily distinguished by their eye structure (7–8 unpigmented facets in A. pecki; 12–15 pigmented facets in A. loebli, Fig. 3F) and antennae (9-segmented in A. pecki; 10-segmented in A. loebli, Fig. 3E). Description. Body length 1.31. 7 mm. Color yellowish white, surface very coarsely and densely punctate, shiny. Head moderately retracted into prothorax (Fig. 5A, E), length ratio pronotum/head ca. 2.1. Lateral antennal grooves open (Fig. 5E). Eyes reduced, well-pigmented, situated at lateral sides of head, each eye with 12–15 facets (Fig. 3F). Mentum subquadrate, as long as wide; submentum pentagonal, cordiform (Fig. 3D). Antenna 10- segmented (Fig. 3E). Pronotum about 0.73X as long as wide, moderately convex, without posterior prominence, sides slightly converging anteriorly, widest at base; anterior angles distinctly produced and narrowly rounded, lower margin of antennal cavity short, lateral edges weakly crenulated; disc with lateral grooves, each continuous with moderately transverse posterior groove, which is crossed by 2 paramedian bridges and another weaker pair laterad of these. Scutellum transverse. Elytra about 1.2–1.3X as long as wide and 2.2X as long as pronotum; sides weakly rounded, widest at anterior 2/5, broadly rounded posteriorly, disc slightly convex, each elytron with 14 rows of punctures at its widest point and 4 rounded costae, which are especially prominent posteriorly; 3 puncture rows between elevated elytral suture (1 st costa, 1 st interval) and 2 nd costa (4 th interval), 3 puncture rows between 2 nd and 3 rd costa (7 th interval), 3 puncture rows between 3 rd and 4 th costa (10 th interval), and 5 puncture rows between 4 th costa and lateral edge (epipleural carina). Epipleuron moderately wide from humerus to level of 1 st abdominal ventrite, then evenly narrowing posteriad (Fig. 3C). Procoxal cavity closed behind by extension of inner process of hypomeron. Procoxae separated by about 1.8X coxal width, prosternum with apex at intercoxal process truncate; mesocoxae separated by about 0.85X coxal width; metaventrite at midline about 0.4X as long as greatest width and about 2.0X as long as metacoxae, moderately convex, slightly flattened in middle. Metacoxae about 0.5X as long as wide and separated by about 0.7X coxal width. Abdominal process rounded, length/width ratio about 1.1. Hindwings absent. Male tarsi all 3- segmented (tarsomeres 3X long as apical tarsomere width) (Fig. 3I, J), female tarsi all 4-segmented (apical tarsomere short). Aedeagus elongate, tegmen about 3.8X as long as wide, apical piece about 1.9X as long as basal piece (Fig. 3H). Type Material. Holotype, male (MHNG): “ Ile Maurice / Magenta / II-4-70 / Y. Gomy ”; 2 specimens (MHNG): “ Ile Maurice / Macchabee Forest / II-4-70 / Y. Gomy ” (Fig. 3G). Paratypes: 3 specimens (MHNG): same data as holotype; 2 specimens (MHNG): “ Ile Maurice / Macchabee Forest / II-4-70 / Y. Gomy ”; 1 specimen (MHNG): “ Ile Maurice / Hollyrood / 2-4-70 / Y. Gomy ”; 1 specimen (MHNG): “ Ile Maurice / Curepipe / 10-I-66. / Petite mare. / Y. Gomy ”. Etymology. This species is named in honor of Ivan Löbl, an outstanding coleopterist. Distribution. This species has been collected in the Mascarene forests of Mauritius in the Afrotropical ecoregion (Fig. 1).
