| 6:01a | [Botany • 2020] Ophiorrhiza monsvictoriae (Rubiaceae, Rubioideae) • A New Species from Natma Taung (Mt.Victoria) National Park, Chin State, Myanmar
Abstract A new species, Ophiorrhiza monsvictoriae S.S.Zhou & L.D.Duan, discovered at Natma Taung (Mt.Victoria) National Park, Chin State, Myanmar, is described and illustrated. The new species is morphologically similar to O. dulongensis, but differs from the latter by its stipules broadly triangular, 2–4 mm long, inflorescence axillary, 1-flowered, bracts lanceolate to subulate, 1–2 mm long, puberulous, calyx pilose, 1–2 mm long, lobes and tube equal length, corolla narrowly funnelform, 15 mm long, puberulous outside. Keywords: NatmaTaung (Mt. Victoria) National Park, taxonomy, new taxon 
Ophiorrhiza monsvictoriae S.S.Zhou & L.D.Duan, sp. nov. Diagnosis: Ophiorrhiza monsvictoriae is similar to Ophiorrhiza dulongensis H. S. Lo (1990: 27), but differs from it by the principal veins raised on both sides of leaf, stipules broadly triangular, 2–4 mm long, inflorescences axillary, 1-flowered, peduncles puberulous, bracts lanceolate to subulate, 1–2 mm long, puberulous, calyx pilose, 1–2 mm long, lobes and tube equal in length, and corolla narrowly funnelform, 15 mm long, puberulous outside, see Table 1. Etymology: The new species was named after Mountain Victoria, Natma Taung National Park, Chin State, southwestern Myanmar, where it was discovered in a vast area of mountain forest. Distribution and habitat: Ophiorrhiza monsvictoriae is only known from the type locality. It is a terrestrial plant that grows in the floating soil on the stone in subtropical evergreen broad-leaved forest, which is dominated by Lithocarpus xylocarpus (Kurz) Markg. (Fagaceae).

| 6:04a | [Entomology • 2020] Philetus kitsi • A New Species of Philetus Melander (Diptera: Empididae) from the Yukon Territory, Canada
The Nearctic genus Philetus Melander, 1928 is a rarely collected group of empidid flies that contains two western species, namely P. memorandus Melander and P. schizophorus Melander. The genus was fully diagnosed by Cumming et al. (2016) with both known species redescribed and their distributions mapped. Here we describe a third species of Philetus from a single male collected recently in the Richardson Mountains of the Yukon Territory in Canada and provide a key to species based on male morphology. Terms used for adult structures follow those of Cumming & Wood (2017) and methods follow those outlined in Cumming et al. (2016).
Philetus kitsi sp. nov. Diagnosis. Philetus kitsi sp. nov. is characterized by male terminalia with elongate simple cercus connected to lengthened ventral subepandrial lobe with digitiform apex (Fig. 3) and thumb-like preapical medially-directed process (Fig. 5), large epandrial lobe with posteriorly hooked dorsal process, and hypandrium with dorsally prolonged narrow median apical process (Figs 3, 4). In addition, the longer more narrowly produced apex of the antennal postpedicel (similar to P. memorandus) separates this species from most specimens of P. schizophorus. Distribution and seasonal occurrence. Known from shrub tundra in the Richardson Mountains of the Yukon Territory, Canada (Fig. 2). The single known male was collected at the end of July. Etymology. This species is named in honour of our colleague, Dr. Joel H. Kits (CNC), who collected the only known specimen of this new species.  Jeffrey M. Cumming and Scott E. Brooks. 2020.
