Andersonaltica denticulata Linzmeier & Konstantinov  , new species

( Figs 1–7View FIGURES 1 – 7, Map 1)

Description. Body ( Figs 1, 2View FIGURES 1 – 7) 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. 4View FIGURES 1 – 7) 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. 3View FIGURES 1 – 7) 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. 6View FIGURES 1 – 7).

Spermatheca with duct without coils, making two turns, first about 130 ° and second about 60 ° ( Fig. 7View FIGURES 1 – 7). Anterior sclerotization of tignum slightly wider than middle part of it ( Fig. 5View FIGURES 1 – 7). 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. 5View FIGURES 1 – 7).

Male unknown.

Type material. Holotype, Ƥ. Labels: 1) GUATEMALA: Zacapa:/ Tuculután, 14km NNE/ 15 º06.864’N 89 º 40.828 ’W / 2270m 6 -VII- 2007 J.Longino/ ex. winkler, cloud forest leaf/ litter LLAMA 07 JTL 6015 -s; 2) Holotype Andersonaltica denticulata  des. 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.
