Description.

Body length 2.43-3.24 mm, width 1.24-1.59 mm, shiny, pilose, with semi-erect hairs, moderately convex in lateral view. Color light brown to dark brown.

Head (Fig. 32D): slightly convex in lateral view, generally reticulated, with sparse pilosity, gena slightly punctured. Frons and vertex forming nearly a 135° angle in lateral view. Antennal callus delineate from vertex by deep and curved supracalinal sulcus. Antennal callus slightly elevated above vertex, surface even, with no or two punctures, if bearing setae, they are short. Orbital sulcus deep. Supraorbital sulcus shallow. Supraorbital and supracallinal sulci not connected. Suprafrontal sulcus shallow. Frontolateral sulcus shallow. Frontogenal suture deep. Orbit wider than transverse diameter of antennal socket. Interantennal space narrower than transverse diameter of eye and as wide as transverse diameter of antennal socket. Frontal ridge short and narrow. Antenna filiform; last five antennomeres slightly wider than preceding ones; second antennomere shorter (Fig. 32C).

Thorax: pronotum (Fig. 32A) much narrower than elytra. Anterior margin wider than posterior, posterior margin nearly straight, lateral margin slightly sinuated. Surface reticulated, slightly punctated, pilose, sparsely covered with variously defined punctures, diameter of which smaller than distance between punctures. Post basal impression absent in females. Pronotal disc weakly raised. Scutellum triangular, shorter than wide. Prosternal surface reticulated. Prosternal intercoxal process thin. Posterior end twice as wide as middle. Procoxae very close to each other. Elytra fused. Elytral surface shiny, with white, semi-erect hairs, punctate (Fig. 32A, B). Punctures forming nine striae, ninth stria almost merge with marginal one. Interspaces convex. Marginal line of elytra interrupted at base. Second and third striae not reaching elytral base. Epipleura slightly convex, nearly vertical, slightly narrowed at elytral apex. Metafemur greatly enlarged, 1.66 times longer than metatibia. Claws appendiculate and long (Fig. 32E).

Male genitalia (Fig. 33A, B): ventral side convex and shiny, without longitudinal impression, slightly flattened at apex; apical denticle well developed, long in ventral view, apex slightly bent ventrally.

Female genitalia (Fig. 33 C–E): tignum long, narrow, slightly bent, with central canal; anterior sclerotization widening gradually with slightly curved sides and convex apex, posterior sclerotization poorly delineated, narrow, as wide as anterior (Fig. 33D). Vaginal palpi elongate, basally strongly sclerotized, each with approximately eight setae at apex (Fig. 33C). Palpi pointed at apex, enlarged at last third but thinned at apex, situated close together and merged anteriorly for more than half of their length. Spermatheca curved, with receptacle and pump not differentiated from each other. Apex of pump with spoon-like projection. Spermathecal duct short, widest at base, without coils, making small loop (Fig. 33E).

Type material.

Holotype, ♂. VENEZUELA: Lara/ P.N.Yacambu, 6.4km/ S.E. Sanare, 1850m/ 09°41'51"N, 69°38'57"W / 17.V.1998-014C/ R.Anderson, cloud for. Litter (MIZA). Paratypes (9♂ 12♀ USNM). (5♂4♀ USNM) Same label as holotype except: (1♂1♀ CMNC) “014A”; (2♂6♀ USNM) “014E”; (1♂1♀ CMNC) “10.4km”, “1800m”, “013B”.

Etymology.

The specific epithet is a noun in apposition based on the type locality.

Differential diagnosis.

Andersonoplatus sanare is similar to A. andersoni but can be differentiated from it based on the following characters: ventral side of median lobe without longitudinal impression (Fig. 33A); spermathecal duct making relatively short loop (Fig. 33E).
