Andersonaltica tuberosa Linzmeier & Konstantinov  , new species

( Figs 33–37View FIGURES 33 – 37, Map 1)

Description. Body ( Figs 33, 34View FIGURES 33 – 37) length 1.76 mm, width 1.07 mm. General body color light chestnut brown. Dorsal part of head and pronotum entirely light chestnut brown. Mouth parts, procoxae, last abdominal ventrite, and basal calli on elytra lighter. Pronotum slightly darker. Elytral hairs yellowish gold, lighter hairs forming two or three narrow, poorly defined bands and patches.

Head ( Fig. 35View FIGURES 33 – 37) 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. 35View FIGURES 33 – 37).

Pronotum ( Fig. 37View FIGURES 33 – 37) 1.36 times wider than long, nearly parallel-sided 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. Basal calli well developed, projecting. Space between scutellar row and first row of punctures as convex as space between first and second rows. Metatibia without preapical tooth situated before tarsal insertion.

Median lobe of aedeagus nearly parallel-sided ventrally, with apex narrowing gradually. Apical part with ventral groove widening gradually towards apex. In lateral view, median lobe slightly curved with base and apex bent evenly ( Fig. 36View FIGURES 33 – 37).

Female unknown.

Type material. Holotype, 3. Labels: 1) GUAT.[ EMALA]: Baja Verapaz/ 4.3km E.Purulha/ 1680m, 29.VI. 1993 / R.Anderson, cloud/ for.litter, 93 - 25 B; 2) Holotype Andersonaltica tuberosa  des. Linzmeier & Konstantinov 2011 ( CMNC).

Etymology. The specific name derived from the Latin tuberosus, referring to the elytra bearing bumps.

Remarks. Andersonaltica tuberosa  is more similar to A. valens  than to other species of the genus. It can be separated from A. valens  by the following characters: pronotum near its base nearly parallel-sided; space between scutellar row and first row of punctures as convex as space between first and second rows; median lobe of aedeagus with ventral groove widening gradually towards apex.
