Lattke col., no. 275, specimen code CASENT0173879 [MIZA]. Worker diagnosis. Body covered by fine, relatively sparse, and partially regular rugulation; promesonotum elevated well above propodeum level, in profile; metanotal groove impressed; propodeal spines straight and thin; teeth of propodeal lobes well developed; surface of first gastral tergite entirely devoid of long hairs. Holotype measurements. HL 0.76; HW 0.72; ML 0.25; SL 0.49; EL 0.16; WL 0.85; PSL 0.21; PL 0.22- 0.39; PPL 0.17; GL 0.99; TL 3.40; CI 96; SI 67; OI 22. Worker description. Color dark ferruginous, with appendages lighter. Head and mesosoma finely covered by vermiculate and predominantly longitudinal rugae, transverse on anterior portion of pronotum, grading to longitudinal on rest of promesonotum; mesopleura and lateral surfaces of propodeum sparsely covered by irregular rugae; mandibles with few and short longitudinal striae restricted to basal portion; petiole and postpetiole irregularly rugose. Abundant pilosity on head, dorsum of promesonotum and waist; dorsum of petiolar node and postpetiole each with more than 10 long hairs; first tergite of gaster entirely devoid of long flexuous hairs. Head longer than broad, with vertexal margin gently convex; frontal lobes subquadrate; eyes with about seven facets at greatest diameter. Promesonotum considerably convex in profile, well above propodeum level; metanotal groove relatively broad and deeply impressed; propodeal spines straight and thin; teeth of propodeal lobes well developed, swollen basally, and with little less than the half-length of propodeal spines. Petiolar node only weakly elevated and rounded dorsally, in lateral view; dorsum of postpetiole slightly convex and without a well definite anteroventral projection. Gyne. Unknown. Etymology. Species named after its collector, the prominent myrmecologist Dr. John E. Lattke, curator of the MIZA ant collection. Comments. This species can hardly be confounded with any other in the genus given the body sculpturation pattern and the combination of elevated promesonotum, and the absence of long hairs on the dorsal surface of first gastral tergite. Lachnomyrmex lattkei is one of the two species in the genus known only from the holotype. The specimen was collected in a leaf litter sample submitted to the Berlese funnel from an 1180m elevation forest in northern Venezuela.Published as part of Feitosa, Rodrigo M. & Brandão, Carlos Roberto F., 2008, A taxonomic revision of the Neotropical myrmicine ant genus Lachnomyrmex Wheeler (Hymenoptera: Formicidae), pp. 1-49 in Zootaxa 1890 on page 21, DOI: 10.5281/zenodo.18430

Moderately erect pilosity on head, promesonotum, petiole, postpetiole and gaster, little on propodeum. Scapes with several erect hairs. Longer hairs about 0.15 mm, those of head shorter. Body light brown to black, appendages lighter. Queen and male: Unknown.

Association of Anagrus amazonensis Triapitsyn, Querino & Feitosa (Hymenoptera, Mymaridae) with aquatic insects in upland streams and floodplain lakes in central Amazonia, Brazil
No full textAnagrus amazonensis Triapitsyn, Querino & Feitosa (Hymenoptera, Mymaridae) is a parasitoid that usesaquatic insect eggs as a host for the development of its immature stages. The objectives of this study areto record the interaction between A. amazonensis and its hosts and the aquatic plants used by these hoststo lay their eggs. Field work was conducted in floodplain lakes and upland (terra firme) streams, in fourmunicipalities in Amazonas State, Brazil, where aquatic plants were scanned for the presence of aquaticinsect eggs. In the laboratory, eggs were maintained in plastic containers with water until the emergenceof the parasitoid or of the first instar insect. A total of 1223 adults of A. amazonensis emerged from eggsof Hemiptera, Lepidoptera and Odonata; these eggs were collected on 12 species of aquatic plants.Autoria: QUERINO [i.e. SILVA], R. B. Q. da.

Body finely and densely covered by vermiculate rugae, somewhat longer and longitudinal on cephalic dorsum, and slightly sparser on mesopleura and lateral surfaces of propodeum; mandibles with short striae restricted to basal portion; petiole and postpetiole strongly and irregularly rugose.

The name refers to the broad vertexal border of the workers head. From Latin: latus: broad, ceps: head.</p> <p>Comments. The excessively dense body pilosity and the dorsally flat head separate this species from the related Lachnomyrmex grandis and L. pilosus. The collections of L. laticeps so far were made during expeditions to 500-1100m mature wet forests in northern Costa Rica. There is a record of workers collected manually beneath a treefern trunk (Longino 2007). John Longino found a L. laticeps nest in a clay bank above a small stream, at Refugio Eladio, 800m elevation in the Penas Blancas river valley. There was a small flaskshaped entrance structure leading to a small chamber. The chamber contained a few workers only, no brood or sexuals (pictures in Longino op. cit.).</p>Published as part of <i>Feitosa, R. M. & Brandão, C. R.
