The following five species are described as new: Manota clava sp. n. (Colombia), Manota multilobata sp. n. (Colombia), Manota perplexa sp. n. (Costa Rica), Manota setilobata sp. n. (Colombia) and Manota subaristata sp. n. (Colombia). In addition, new records for the following 11 species are presented: Manota acuminata Jaschhof & Hippa, 2005 (Costa Rica), Manota arenalensis Jaschhof & Hippa, 2005 (Costa Rica), Manota corcovado Jaschhof & Hippa, 2005 (Costa Rica), Manota costaricensis Jaschhof & Hippa, 2005 (Costa Rica), Manota diversiseta Jaschhof & Hippa, 2005 (Colombia, Brazilian Amazonia, Costa Rica), Manota minutula Hippa, Kurina & Sääksjärvi, 2017 (Brazilian Amazonia), Manota multisetosa Jaschhof & Hippa, 2005 (Costa Rica), Manota parva Jaschhof & Hippa, 2005 (Colombia, Costa Rica), Manota pisinna Hippa & Kurina, 2013 (Brazilian Amazonia), Manota spinosa Jaschhof & Hippa, 2005 (Colombia) and Manota squamulata Jaschhof & Hippa, 2005 (Costa Rica). Distribution patterns include (1) species known only locally in Costa Rica or Colombia, (2) distributions connecting Central America to west Andes lowlands, and (3) north-west Neotropical components, extending from Central America to Brazilian Amazonia. The possible biogeographical and taxonomical context of Manota species with a widespread distribution is considered.

The monophyletic subfamily Manotinae of Mycetophilidae is represented by four extant genera in the world fauna, but only Manota Williston (type species Manota defecta Williston) has almost cosmopolitan distribution, with the highest diversity in tropical areas (e.g.
The last 15 years revealed an explosion in the number of described Manota species. The number of species of the genus in the world increased from 28 (
The aim of this study is to increase the knowledge of the genus Manota in the Neotropical region by describing new species and by giving new records based on material collected in Colombia, Brazilian Amazonia, and Costa Rica.
The Colombian material was collected by Malaise traps within the framework of a collection project leaded by Dr. M. Sharkey (National Science Foundation Grant DEB-0205982; see also
All the material was initially stored in ethyl alcohol. In most cases, the hypopygium was detached from the specimen and macerated in warm 20% potassium hydroxide (KOH). Several specimens, especially those collected in Colombia, were faded after being more than a decade in alcohol. After macerating in KOH and washing in distilled water, the hypopygium was stained with Chlorazol Black and thereafter mounted in “Euparal” between two pieces of coverslip, which allowed a study from both sides under a compound microscope. These preparations are now attached to a normal microscope slides by two strips of adhesive tape across their edges and are easily detached when needed, together to the remainder of the body, which was not macerated, but dehydrated and mounted in “Euparal” under a coverslip.
The morphological terminology follows mainly

The setose laterotergite, non-setose anterior basalare, sternite 9 laterally free from gonocoxa, and gonocoxa without a remarkable posterolateral lobe group together Manota clava sp. n. with M. caribica Jaschhof & Hippa, 2005 (Costa Rica) and M. micula Hippa & Kurina, 2013 (Ecuador, Peru). All three species have also the sternite 9 posteriorly broadly concave and a similar aggregation of setae on plate-like lobe ventrally from dorsal medial margin of gonocoxa. Parastylar lobe is distinct between all three species: large, apically broadened with 3–5 posterior setae in M. clava, large, subtriangular with three posterior setae in M. micula and small, stout with 2–3 setae posteroapically in M. caribica. The gonostylus of M. clava is subrectangular and posterolaterally drawn out while it is oval or almost circular in case of the two other species. Manota clava and M. micula have the juxtagonostylar megasetae complex with transverse and leaf-like expansions, while they are simple and pointed in M. caribica.
The specific epithet is Latin, clava [club or mace], referring to the prominent club-shaped parastylar lobe, and is a noun used as in apposition.

Discussion. Manota multilobata sp. n. groups together with M. setilobata sp. n. by having the non-setose anterior basalare, non-setose laterotergite, indistinct or short posterolateral lobes of the gonocoxa, and the megasetae and aggregations of setae at the dorsal medial margin of the gonocoxa all placed far posteriorly. Both species have the obovate gonostylus, which is somewhat sunken into the gonocoxa, and have 4–5 strong apical and subapical setae deviating from other setae, similar arrangement of small setose lobes around juxtagonostylar setae, and sternite 9 basally fused with the gonocoxa. The species differ as follows: 1) in M. multilobata there are two finger-like lobes close together anteriorly from the juxtagonostylar megaseta, the more anterior one with one, the more posterior one with three strong setae (in M. setilobata there is a plate-like lobe anteriorly bearing one seta widely separated from a posterior group of several setae), 2) in M. multilobata posteriorly from the juxtagonostylar megasetae there is a finger-like lobe with one strong and one weak seta (in M. setilobata a flat lobe with numerous fine setae), 3) in M. multilobata the gonocoxa is drawn into a short and broad posterolateral lobe (in M. setilobata it is drawn into a short and narrow lobe), and 4) in M. multilobata sternite 9 has the posterior margin broadly v-shaped incised (in M. setilobata there is narrow and deep medial cleft).
The specific epithet is Latin, multilobata [many-lobed], referring to the setigerous lobes dorsally on the gonostylus (adjective).

Manota subaristata sp. n. is similar to M. aristata Hippa & Kurina, 2013 in having the dorsal juxtagonostylar megaseta with a long whip-like branch. Manota subaristata, however, has the megaseta subbasally geniculate, arising from a separate basal body, while it is basally straight and arising from apical half of the common basal body with the ventral juxtagonostylar seta in M. aristata. Manota subaristata has 3–4 strong setae on a finger-like setose lobe posteriorly from the juxtagonostylar megaseta, which are absent in M. aristata. By the latter character, the species resembles M. acutistylus Jaschhof & Hippa, 2005, but the megasetae at the dorsal medial margin of gonocoxa in M. subaristata are longer and there are two of them in the posterior group, not three as in M. acutistylus (see also the discussion for M. aristata in

A distribution map of the species described in this paper is depicted in Fig.
There are general patterns known for the Neotropical region (
The observed Manota distribution patterns show individual species with a considerably wide distribution, which fit in this larger pattern—named as North-west Neotropical (
Although the patterns sometimes are obvious, explanations can be more complex. Nominal species distributions that enclose areas of different endemism may correspond to: (1) secondary expansion of younger species with prior local distribution; (2) lack of response of older species to barriers that affected the younger groups; or (3) clades with undetected, cryptic species. This cannot be answered for the Manota species in question. A phylogeographic study would be useful to verify whether populations of these widespread species at the extremes of their distribution are beyond the threshold of genetic differentiation, often used to recognized separate species. This kind of problem of insect species is hard to distinguish using only morphological features, as they can involve also “hidden” molecular divergence. This aspect has been addressed in a number of recent papers (e.g.
