Alevonota (Alevonota) hierroensis View in CoL sp. n. ( Figs 69-73 View Figs 64-73 )

Type material:

Holotype : “Hierro, 22-II-2006, Cueva Longueras, P. Oromí / Holotypus  Alevonota hierroensis sp. n. det. V. Assing 2008” ( DZUL) . Paratype  [teneral]: same data as holotype (cAss).

Description:

2.0- 2.2 mm; RL: 1.1-1.2 mm. Coloration of whole body pale yellowish. Habitus as in Fig. 69 View Figs 64-73 .

Head distinctly oblong, HL/HW: 1.2; puncturation extremely fine and sparse, barely visible; microsculpture very shallow, integument glossy ( Fig. 70 View Figs 64-73 ). Eyes reduced to minute, barely visible rudiments without ommatidia and pigmentation. Antenna rather long and slender, reaching posterior margin of elytra when directed caudad; antennomere IV approximately as long as wide;

V weakly transverse; V-X gradually and weakly increasing in width; X less than 1.5 times as wide as long ( Fig. 71 View Figs 64-73 ).

Pronotum approximately as wide as long and 1.2 times as wide as head, widest in anterior half, distinctly narrowed caudad; posterior angles weakly marked; puncturation extremely fine, barely visible; microsculpture slightly more distinct than that of head ( Fig. 70 View Figs 64-73 ).

Elytra approximately 0.80-0.85 times as long as pronotum; puncturation fine, but more distinct than that of pronotum; microsculpture slightly more pronounced than that of pronotum. Hind wings completely reduced. Metatarsomere I approximately as long as II or slightly longer.

Abdomen distinctly broader than forebody, approximately 1.3 times as wide as pronotum, widest at segments V/VI; posterior margin of tergite VII without palisade fringe.

: posterior margin of tergite VIII broadly and distinctly concave, that of sternite VIII strongly convex; median lobe of aedeagus with ventral process distinctly curved in lateral view ( Fig. 72 View Figs 64-73 ); ML: 0.35 mm.

: posterior margin of tergite VIII very weakly concave, almost truncate; posterior margin of sternite VIII weakly convex; spermatheca with moderately enlarged capsule and with short, apically truncate duct ( Fig. 73 View Figs 64-73 ).

Etymology: The name (Latin, adjective) is derived from the name of the island, where the type locality is situated.

Distribution and bionomics:

Alevonota hierroensis is doubtlessly endemic to the Canarian island El Hierro, where it is the only known representative of the genus. As can be inferred from the adaptive reductions of the eyes, the pigmentation, and the wings, as well as from its habitus (moderately slender body with moderately long appendages), the species is probably microcavernicolous. The type specimens were collected with pitfall traps in a cave in February. The male paratype is teneral.
