A new genus of minute stingless bees from Southeast Asia (Hymenoptera, Apidae).

A new genus of minute stingless bees (Meliponini: Hypotrigonina) is described from Southeast Asia. Ebaiotrigona Engel & Nguyen, gen. nov., is based on the type species Lisotrigonacarpenteri Engel, recorded from Vietnam, Thailand, Laos, Cambodia, and southern China. The species was previously considered an enigmatic member of Lisotrigona Moure, but is removed to a new genus based on its unique male terminalia that differs considerably from that of Lisotrigona and instead shares resemblances with Austroplebeia Moure, and the presence of yellow maculation (also similar to that of Austroplebeia). It is possible that Ebaiotrigona is the extant sister group of Austroplebeia, but this requires confirmation by future phylogenetic analyses. Based on available biological observations, Ebaiotrigonacarpenteri could not be confirmed as lachryphagous as is well documented from the tear-drinking species of Lisotrigona and Pariotrigona Moure.

Measuring the quality of early childhood education: Associations with children's development from a national study with the IMCEIC tool in Colombia.

National-level monitoring of quality of early childhood education (ECE) is key to achieving inclusive and equitable education. Most countries report structural quality while process characteristics are rarely observed at the national level. This study examined the associations between ECE and children's development in a middle-income country using data from a nationally representative sample of public centers serving Colombian children (N = 3163; M = 4.3 years, 50% girls; 42% Mestizo, 16% White, 15% Afro-Colombian, 4% Indigenous, 23% not reported). Descriptive findings evidenced low to moderate quality. Multilevel models showed several positive associations between structural and process quality and child outcomes. Results have implications for the existing literature and highlight the feasibility of quality monitoring in low- and middle-income countries.
