STEVENALTICA, A NEW GENUS OF MOSS AND LEAF-LITTER INHABITING FLEA BEETLES FROM BOLIVIA (COLEOPTERA: CHRYSOMELIDAE: GALERUCINAE: ALTICINI).

A new genus, Stevenaltica, with two new species, S. normi and S. erronis, from Bolivia is described and illustrated. It is similar to Exoceras Jacoby. An identification key for all flea beetle genera known to occur in mosses in the Western Hemisphere is provided

DISCOVERY OF THE FIRST NEARCTIC MOSS-EATING FLEA BEETLE, DISTIGMOPTERA BOREALIS BLAKE, 1943 (COLEOPTERA: CHRYSOMELIDAE: GALERUCINAE: ALTICINI)

A flea beetle, Distigmoptera borealis Blake, 1943, is documented for the first time to feed on liverworts, Reboulia hemisphaerica (L.) Raddi (Aytoniaceae), and moss, Weissia controversa Hedw. (Pottiaceae). This is the first and only known bryobiont leaf beetle in the USA and Nearctic biogeographic region. The adult of D. borealis is redescribed and illustrated, and the larva and pupa of D. borealis are described and illustrated for the first time

All the specimens were collected in leaf litter by R. Anderson and S. and J. Peck. Andersonoplatus is compared to Andersonaltica Linzmeier & Konstantinov, Apleuraltica Bechyne, Distigmoptera Blake and Ulrica Scherer

Andersonaltica denticulata Linzmeier & Konstantinov, new species

Andersonaltica denticulata Linzmeier & Konstantinov, new species (Figs 1–7, Map 1) Description. Body (Figs 1, 2) length 1.79–1.84 mm, width 1.07 –1.15 mm. Dorsal part of head, pronotum, and elytra very dark brown to oily black, ventral part of body and three middle antennomeres dark chestnut brown; legs and apical and basal antennomeres light chestnut brown. Elytral hairs moderately long, barely curved, greenish yellow, not forming bands. Head (Fig. 4) with flat vertex, lacking longitudinal ridge above antennal calli. Frontal ridge acute ventrally, followed by narrow longitudinal ridge beyond anterofrontal ridge into middle of clypeus. Anterofrontal ridge poorly developed laterally. Head surface sparsely covered with relatively long, well visible setae. Pronotum (Fig. 3) 1.86 times wider than long. In lateral view apical part as convex as basal. Lateral margin straight. Anterolateral pore present. Two elongate elevations on pronotum short. Pronotal punctures large, spaced unevenly, distance between them about as small as diameter of puncture. On pronotal elevations punctures much sparser. Elytral punctures in striae spaced as far from each other as striae between themselves, interspaces flat. Basal calli projected. Metatibia with preapical tooth situated before tarsal insertion (Fig. 6). Spermatheca with duct without coils, making two turns, first about 130 ° and second about 60 ° (Fig. 7). Anterior sclerotization of tignum slightly wider than middle part of it (Fig. 5). Posterior sclerotization of vaginal palpi with six or seven setae. Inner side of posterior sclerotization slightly curved, mid part slightly bulging. Vaginal palpi connected for more than half of their length (Fig. 5). Male unknown. Type material. Holotype, Ƥ.

Linzmeier & Konstantinov 2011 (CMNC). Paratype, 1 Ƥ. Same labels as holotype (USNM). Etymology. The specific name, derived from the Latin denticulatus, refers to a small tooth on the metatibia situated above the insertion of the metatarsus. Remarks. Andersonaltica denticulata can be immediately separated from the rest of the species by the presence of the preapical tooth on the metatibia. The remaining four species lack this tooth. In addition, the pronotum of A. denticulata is much shorter than in the rest of the species.Published as part of Linzmeier, Adelita M. & Konstantinov, Alexander S., 2012, A new genus of leaf litter inhabiting Neotropical Monoplatina (Coleoptera: Chrysomelidae: Galerucinae: Alticini), pp. 19-32 in Zootaxa 3260 on page 22, DOI: 10.5281/zenodo.24617

Andersonaltica valens Linzmeier & Konstantinov, new species

Andersonaltica valens Linzmeier & Konstantinov, new species (Figs 38–42, Map 1) Description. Body (Figs 38, 39) length 1.82 mm, width 1.12 mm. General body color dark chestnut brown. Dorsal part of head and pronotum entirely dark chestnut brown. Mouth parts, procoxae, last abdominal ventrite, and basal calli on elytra lighter. Pronotum slightly darker. Elytral hairs yellowish gold to brown, lighter hairs forming two or three narrow, poorly defined bands and patches. Head (Fig. 40) with vertex with slightly zigzagged longitudinal ridge above antennal calli. Frontal ridge acute ventrally, followed by narrow longitudinal ridge beyond anterofrontal ridge into middle of clypeus. Anterofrontal ridge well developed laterally. Head surface densely covered with relatively long, well visible setae (Fig. 40). Pronotum (Fig. 42) 1.36 times wider than long, abruptly constricted near its base. In lateral view apical part more convex than basal. Lateral margin slightly convex. Anterolateral pore present. Two elongate elevations on pronotum tall. Pronotal punctures large, spaced evenly, distance between them much smaller than diameter of puncture. Elytral punctures placed close together into striae, interspaces convex. Space between scutellar row and first row of punctures less convex than space between first and second rows. Basal calli well developed, projecting. Metatibia without preapical tooth situated before tarsal insertion. Median lobe of aedeagus nearly parallel-sided ventrally, with apex narrowing gradually and with ventral groove widening abruptly towards apex. In lateral view, median lobe slightly curved with base and apex bent evenly (Fig. 41). Female unknown. Type material. Holotype, 3. Labels: 1) MEXICO: Chiapas, Lagos/ de Montebello, Cinco Lagos/ 1500m, 22.IX.1992, 92- 113 / R.S.Anderson, liquidambar/ oak/pine forest litter; 2) Andersonaltica valens des. Linzmeier & Konstantinov 2011 (CMNC). Etymology. The specific name, derived from the Latin valens, meaning strong, vigorous, refers to strong sculpture on the elytra. Remarks. Andersonaltica valens is more similar to A. tuberosa than to other species of the genus. It can be separated from A. tuberosa by the following characters: pronotum near its base abruptly constricted; space between scutellar row and first row of punctures less convex than space between first and second rows; median lobe of aedeagus with ventral groove widening abruptly towards apex.Published as part of Linzmeier, Adelita M. & Konstantinov, Alexander S., 2012, A new genus of leaf litter inhabiting Neotropical Monoplatina (Coleoptera: Chrysomelidae: Galerucinae: Alticini), pp. 19-32 in Zootaxa 3260 on pages 29-32, DOI: 10.5281/zenodo.24617
