The Beck Anxiety Inventory (BAI; Beck, A.T., Epstein, N., Brown, G., Steer, R.A., 1988. An inventory for measuring clinical anxiety: psychometric properties. J. Consult. Clin. Psychol. 56, 893-897) is intended to assess clinical anxiety symptoms that are distinct from depressed mood, and there is some preliminary empirical support for this differential assessment. The BAI may serve a useful complementary role when used with the popular Beck Depression Inventory (BDI; Beck, A.T., Rush, A.J., Shaw, B.F., Emery, G., 1979. Cognitive Therapy of Depression: A Treatment Manual. Guilford Press, New York, NY; Beck, A.T., Ward, C.H., Mendelson, M., Mock, J., Erbaugh, J., 1961. An inventory for measuring depression. Arch. Gen. Psychiatry 4, 561-571), in patients with mood and/or anxiety disorders. Accordingly, the present paper reports the results of the first confirmatory factor analysis of the Beck scales in a homogeneous, clinically depressed sample (137 outpatients with non-psychotic major depressive disorder). Results indicated that a multidimensional model of separate anxiety and depression factors had good fit to the data. However, the parameter estimate was very high (0.784) and a unidimensional, single-factor model of negative affectivity approached the criteria for good fit. It was concluded that the Beck Anxiety and Depression Inventories assess distinct anxiety and depression phenomena to a limited extent when used in a clinically depressed sample.

The Indianspeciesof the ant genus Cerapachys Smith are keyed. Twelve species are recognized of which 6 are described as new. The species are: Cerapachys aitkenii Forel, Cerapachys alii sp. n., Cerapachys anokha sp. n., Cerapachys besucheti Brown, Cerapachys biroi Forel, Cerapachys indicus Brown, Cerapachys longitarsus (Mayr), Cerapachys nayana sp. n., Cerapachys schoedli sp. n., Cerapachys seema sp. n., Cerapachys sulcinodis Emery and Cerapachys wighti sp. n. Geographic distribution and group affinities of the new species are discussed. A revised key to the Indian species is provided. The rare ergatoid queens of Cerapachys nayana, Cerapachys schoedli and Cerapachys seema are reported. Formed in response to selective pressures these ergatoid queens have a significant role in dispersal strategies and contribute much to our understanding of the biology of these ants.

The genus Mystrium is revised for the Malagasy region. Six species, Mystrium barrybressleri sp. n., Mystrium labyrinth sp. n., Mystrium eques sp. n., Mystrium mirror sp. n., Mystrium shadow sp. n., and Mystrium janovitzi sp. n. are described as new. Two existing names, Mystrium fallax Forel and Mystrium stadelmanni Forel, are synonymized with Mystrium voeltzkowi Forel and Mystrium mysticum Roger, respectively. All recognized species, including species outside of the Malagasy region, are assigned to one of the three newly proposed species groups. The associations between existing names and males are reexamined, and males of eight of the ten Malagasy species are described or redescribed. The taxonomic history of Mystrium highlights the importance of using unique identifiers when designating type specimens and the use of deposited vouchers in phylogenetic and ecological studies. Keys to species for workers, queens, and males are provided. Furthermore, a neotype for Mystrium mysticum is designated, as well as lectotypes for Mystrium camillae Emery, Mystrium rogeri Forel, Mystrium fallax Forel, Mystrium oberthueri Forel, Mystrium stadelmanni Forel, and Mystrium voeltzkowi Forel. Stigmatomma gingivale (Brown) is reassigned to Amblyopone as comb. rev. and Amblyopone awa Xu & Chu, Amblyopone kangba Xu & Chu, Amblyopone meiliana Xu & Chu, and Amblyopone zomae Xu & Chu are transferred to the genus Stigmatomma as comb. n.

The ant genus Octostruma is restricted to the Neotropics, where it is an inhabitant of forest leaf litter and soil. The genus is reviewed, with an emphasis on the fauna of the MesoAmerican corridor. A total of 34 species are recognized, of which 19 are described as new. A key to species is provided, and the following new species are described: O. ascrobicula Long-ino, sp. nov., O. ascrobis Longino, sp. nov., O. convallis Longino, sp. nov., O. convallisur Longino, sp. nov., O. cyrtino-tum Longino, sp. nov., O. excertirugis Longino, sp. nov., O. gymnogon Longino, sp. nov., O. gymnosoma Longino, sp. nov., O. leptoceps Longino, sp. nov., O. limbifrons Longino, sp. nov., O. megabalzani Longino, sp. nov., O. montanis Longino, sp. nov., O. obtusidens Longino, sp. nov., O. pexidorsum Longino, sp. nov., O. planities Longino, sp. nov., O. schusteri Longino, sp. nov., O. triquetrilabrum Longino, sp. nov., O. triangulabrum Longino, sp. nov., and O. trithrix Longino, sp. nov. Octostruma lutzi (Wheeler) and O. amrishi (Makhan) are removed from synonymy with O. balzani (Emery). Queens are newly associated with workers for O. amrishi (Makhan), O. rugiferoides Brown & Kempf, and O. wheeleri (Mann).

The species of the ant genus Strumigenys Smith, 1860 found in Hong Kong are reviewed based on new sampling efforts performed over the past five years (2014-2018). Prior to this, 12 Strumigenys species had been recorded from Hong Kong, all confirmed here. Moreover, we add to this list three newly described species: S.hirsuta sp. n., S.lantaui sp. n., and S.nathistorisoc sp. n., and describe for the first time the worker caste of S.formosa Terayama, Lin & Wu, 1995. We report new records for nine additional species, bringing the total number of species to 24, including four newly recorded species (S.hexamera Brown, 1958, S.membranifera Emery, 1869, S.nepalensis Baroni Urbani and De Andrade, 1994, and S.rogeri Emery, 1890) which are considered to be introduced to Hong Kong. A global review of the introduced Strumigenys species is presented. The taxonomic validity of S.feae and S.formosensis is discussed in light of new specimen measurements. New ecological information on the swarming periods of 11 species is presented on the basis of year-long sampling of aerial insects. Finally, the importance of our results within Southeast Asia and the need for future sampling efforts in the region is discussed.
