description: Cylindromorphoides katrinae sp. n.
Holotype (male): “ Venezuela, Edo. Bolivar, Gran Sabana, nr. El Pauji, lat 04°27’ N, long 61°36’ W, ca. 800m 14.03.1995, leg. M. Hornburg”.
The holotype will be deposited in the Museum für Naturkunde der Humboldt­Universität zu Berlin (ZMHB), Germany
Description
Measurements: total length: 6.0 mm; width: 1.6 mm.
Head: light golden­red with green frons; sparsely, regularly punctured with very fine micro­sculpture between the punctation; punctures with fine white setae; head with longitudinal furrow, deepest at frons; head appears bilobed, the protruding eyes emphasize this form; one row of strong punctures along posterior of eyes; frons more strongly microsculptured; single puncture above each antennal insertion; epistoma deeply emarginate medially with second, more shallowly, concave margin on each side, forming two fine, closely micro­sculptured teeth.
Antennae: slender, bronze; close­fitting laterally, reaching middle of pronotum; with fine white setae from third antennomere; fifth to tenth antennomeres serrate, eleventh slen­ der oval.
Pronotum: light bronze color with red­golden reflection; greatest width in anterior third; weakly transverse, 1.6 times broader than long, slightly narrower than anterior margin of elytra; surface punctured like head, very fine micro­sculpture, fine white pilosity between punctures; anterior portion regularly rounded with smooth margin; posterior margin tri­sinuate; strong transverse depression in middle; depression bound laterally by very distinct, coarse prehumeral­ridge; between arched prehumeral­ridge and weak s­shaped lateral margin, strongly micro­sculptured, with very fine pilosity.
Scutellum: bronze colored; anterior part arcuately rounded, sides straight, nearly equilateral; surface finely micro­sculptured.
Elytra: light bronze colored; opposite metacoxa narrower, anterior and posterior portions nearly of same width, widest just posteriad protruding humeri; elytra 2.6 times longer than wide; flat convex, apices separately rounded; punctation, in general very densely and transversely merged; anterior stronger transversely rugose; between punctures shiny, very regularly and closely clothed with fine white pilosity.
Ventral side: darker bronze colored and sparsely pilose; very fine micro-sculptured.
Legs: color like ventral surface, also finely micro-sculptured; femora on inner side with white pilose; tibiae sparsely pilose on external margin; all tibiae weakly arcuate; metatibiae before distal end with a comb of longer white setae.
Aedeagus (Fig. 4): length 1.5mm, four times longer than broad; parameres straight laterally, divergent, rounded preapically and separately attenuate; after obtuse arch on inner side it extends parallel for half of incision, then converges; lateroposterior part of parameres clothed with long upright, silky setae.
Derivatio nominis: in gratitude to my dear companion Katrin.
3 4 Cylindromorphoides agriliformis, male Cylindromorphoides katrinae sp. n.
Distribution
Venezuela, Gran Sabana. Known only from the type locality (Fig. 5).
Remarks
The type locality of Cylindromorphiodes katrinae sp. n. is close to a mountain-ridge, covered with ombrophilic and xerophilic vegetation (Fig. 5), known as “El Abismo”, because of the very nice view over the large humid valley of the “Rio Icabaru” (Fig. 6). There are, well-founded to the high-distance and the different climate-conditions, often strong upper winds. It is likely, that this species is native to this type of landscape, how it could be found on that mountain-ridge, but it is also possible, that it was carried up by the wind. Nothing is known about possible host-plants of either species. A later journey to this region, in the year 2001, in intention to collect further specimens, was unsuccessful on that score.
