To expand content of the physical function domain of the Work Disability Functional Assessment Battery (WD-FAB), developed for the US Social Security Administration’s (SSA) disability determination process.

Newly developed questions were administered to 3,532 recent SSA applicants for work disability benefits and 2,025 US adults. Factor analyses and item response theory (IRT) methods were used to calibrate and link the new items to existing WD-FAB, and computer-adaptive test simulations were conducted.

Factor and IRT analyses supported integration of 44 new items into 3 existing WD-FAB scales and the addition of a new 11-item scale (Community Mobility). The final physical function domain consisting of: Basic Mobility (56 items), Upper Body Function (34 items), Fine Motor Function (45 items), and Community Mobility (11 items) demonstrated acceptable psychometric properties.

The WD-FAB offers an important tool for enhancement of work disability determination. The FAB could provide relevant information about work-related functioning for initial assessment of claimants, identifying denied applicants who may benefit from interventions to improve work and health outcomes; enhancing periodic review of work disability beneficiaries; and assessing outcomes for policies, programs and services targeting people with work disability.

We describe 22 new species in the genus Hyphantrophaga Townsend, 1892 (Diptera: Tachinidae) from Area de Conservacion Guanacaste (ACG) in north-western Costa Rica. All species were reared from an ongoing inventory of wild-caught caterpillars spanning a variety of families (Lepidoptera: Bombycidae, Crambidae, Depressariidae, Doidae, Erebidae, Euteliidae, Gelechiidae, Geometridae, Hedylidae, Hesperiidae, Immidae, Lasiocampidae, Limacodidae, Megalopygidae, Mimaloniidae, Noctuidae, Nolidae, Notodontidae, Nymphalidae, Papilionidae, Pieridae, Phiditiidae, Pterophoridae, Pyralidae, Riodinidae, Saturniidae, Sphingidae, Thyrididae, Tortricidae and Zygaenidae). We provide a morphological description of each species together with information on life history, molecular data and photographic documentation. In addition to the new species, we provide a redescription of the genus, as well as the redescription of three previously described species, which were also collected within ACG during this study: Hyphantrophaga angustata (van der Wulp), Hyphantrophaga myersi (Aldrich) and Hyphantrophaga virilis (Aldrich & Webber).

New information
The following 22 new species of Hyphantrophaga are described: Hyphantrophaga adrianguadamuzi Fleming & Wood sp. n., Hyphantrophaga albopilosa Fleming & Wood sp. n., Hyphantrophaga anacordobae Fleming & Wood sp. n., Hyphantrophaga calixtomoragai Fleming & Wood sp. n., Hyphantrophaga calva Fleming & Wood sp. n.., Hyphantrophaga ciriloumanai Fleming & Wood sp. n., Hyphantrophaga danausophaga Fleming & Wood sp. n., Hyphantrophaga diniamartinezae Fleming & Wood sp. n., Hyphantrophaga duniagarciae Fleming & Wood sp. n., Hyphantrophaga edwinapui Fleming & Wood sp. n., Hyphantrophaga eldaarayae Fleming & Wood sp. n., Hyphantrophaga eliethcantillanoe Fleming & Wood sp. n., Hyphantrophaga gilberthampiei Fleming & Wood sp. n., Hyphantrophaga guillermopereirai Fleming & Wood sp. n., Hyphantrophaga hazelcambroneroae Fleming & Wood sp. n., Hyphantrophaga luciariosae Fleming & Wood sp. n., Hyphantrophaga manuelriosi Fleming & Wood sp. n., Hyphantrophaga morphophaga Fleming & Wood sp. n., Hyphantrophaga nigricauda Fleming & Wood sp. n., Hyphantrophaga osvaldoespinozai Fleming & Wood sp. n., Hyphantrophaga pabloumanai Fleming & Wood sp. n. and Hyphantrophaga similis Fleming & Wood sp. n.

The following are proposed by Wood as new synonyms of Hyphantrophaga Townsend, 1892: Brachymasicera Townsend, 1911 syn. n., Ommasicera Townsend, 1911 syn. n., Ophirosturmia Townsend, 1911 syn. n., Patillalia Curran, 1934 syn. n. and Ypophaemyiops Townsend, 1935 syn. n.

The following nine new combinations are proposed as a result of the new synonymies: Hyphantrophaga adamsoni (Thompson, 1963), comb. n., Hyphantrophaga fasciata (Curran, 1934), comb. n., Hyphantrophaga glauca (Giglio-Tos, 1893), comb. n., Hyphantrophaga gowdeyi (Curran, 1926), comb. n., Hyphantrophaga myersi (Aldrich, 1933), comb. n., Hyphantrophaga nigripes (Townsend, 1928), comb. n., Hyphantrophaga optica (Schiner, 1868), comb. n., Hyphantrophaga polita (Townsend, 1911), comb. n., Hyphantrophaga subpolita (Townsend, 1912), comb. n.

A large number of structural determinations of compounds containing 2-hy­droxy-3,5-di­nitro­benzoic acid (I) and its various deprotonated forms, 2-hy­droxy-3,5-di­nitro­benzoate (II) or 2-carb­oxy-4,6-di­nitro­phenolate (III), are biased. The reason for the bias follows from incorrectly applied constraints or restraints on the bridging hydrogen, which is involved in the intra­molecular hydrogen bond between the neighbouring carb­oxy­lic/carboxyl­ate and oxo/hy­droxy groups. This hydrogen bond belongs to the category of resonance-assisted hydrogen bonds. The present article suggests corrections for the following structure determinations that have been published in Acta Crystallographica: DUJZAK, JEVNAA, LUDFUL, NUQVEB, QIQJAD, SAFGUD, SEDKET, TIYZIM, TUJPEV, VABZIJ, WADXOR, YAXPOE [refcodes are taken from the Cambridge Structural Database [CSD; Groom et al. (2016 ▸). Acta Cryst. B72, 171-179]. The structural features of the title mol­ecules in all the retrieved structures, together with structures that contain 3,5-di­nitro-2-oxidobenzoate (IV), are discussed. Attention is paid to the localization of the above-mentioned bridging hydrogen, which can be situated closer to the O atom of the carboxyl­ate/carb­oxy­lic group or that of the hy­droxy/oxo group. In some cases, it is disordered between the two O atoms. The position of the bridging hydrogen seems to be dependent on the pK a(base) although with exceptions. A stronger basicity enhances the probability of the presence of a phenolate (III). The present article examines the problem of the refinement of such a bridging hydrogen as well as that of the hydrogen atoms involved in the hy­droxy and primary and secondary amine groups. It appears that the best model, in many cases, is obtained by fixing the hydrogen-atom position found in the difference electron-density map while refining its isotropic displacement parameter.
